2. Course Overview

GEOG 861: The Earth is Round and Maps are Flat: Spatial Reference Systems for GIS

This class cultivates a working knowledge of geodetic datums, map projections, and grid systems that professionals need to process geospatial data effectively for mapping and analysis.
Prerequisites: GEOG 484 or permission of the instructor.

This course discusses three fundamental mapping topics: geodetic datums, map projections, and grid systems.

2.1. Geodetic Datums

Generally speaking, a geodetic datum is a mathematical model that describes Earth’s size and shape. More specifically, a geodetic datum... 

  1. is a set of constants specifying the coordinate system used for geodetic control
  2. is combined with the coordinate system and the set of all points and lines whose coordinates, lengths, and directions have been determined by measurement and calculation and applied to Earth's surface

The first definition is realized, for example, by specifying an ellipsoid and associated origin and orientation information. This definition represents an idealization of a geodetic datum - not attached to Earth's surface . The second definition, which is prevalent in mapping and charting, is realized, for example, by specification of ellipsoid, origin, and orientation in combination with a self-consistent set of observed reference coordinates. This second definition expresses the realization of a geodetic datum by attaching it to Earth's surface thus making it useable. Geodetic datums are important to many applications such as surveying, mapping, and navigation as different datums each provide positions and heights with varied accuracies. Geometric datums (historically referred to as horizontal datums)accurately set the origin of Earth’s latitude and longitude network (providing horizontal control). Geopotential datums (historically called vertical datums) set the origin for heights (providing vertical control). Geometric datums can be divided into those that quantify local and global geographic extents. Local geometric datums such as the North American Datum of 1927 (NAD27) were developed to accurately represent localized areas (i.e., North America). Other geometric datums such as the World Geodetic Survey of 1984 (WGS84) were developed to accurately represent the entire world. Hundreds of geometric datums have been developed, each trying to model Earth’s size and shape more accurately than another. Using the wrong datum for a geographic location can lead to considerable error in horizontal coordinate accuracies. Geopotential datums have been developed to model heights across Earth's surface. Generally, three types of datums have been developed establishing control for heights. For example, tidal variations measured over a set time period are called tidal datums, orthomertic datums are based on Earth's gravity, and ellipsoid datums report ellipsoid heights. Geopotential datums define exact heights and are important in mapping activities such as flood plain mapping. If you work with spatial data, you need to be aware of differences in positioning and heights that geometric and geopotential datums provide and how those differences will impact your mapping activities.

2.2. Map Projections

Map projections are mathematical formulae by which geographical coordinates representing positions on Earth (i.e., latitude and longitude) that are transformed to 2D plane coordinates and represent locations on two-dimensional maps. A natural consequence of the projection process is distortion. No map is an error-free representation of Earth’s two-dimensional curved surface. Distortion can negatively impact various kinds of measurement tasks that are carried out on a map. Knowledge of distortion patterns on a map is important to understand so that distortion can be mitigated over the mapped area leading to accurate map analysis. Map projection formulae are implemented as algorithms in geographic information systems (GIS), image processing, and other kinds of mapping and analysis software. Although many types of map projections are available, only certain types are well suited to any given mapping or analysis task. There is no best map projection and selecting a map projection involves compromises and trade-offs. Furthermore, since GIS often involves merging multiple datasets, each of which is likely to be the product of a different projection, GIS professionals need to be knowledgeable about this specialized topic.

There is often confusion between the role of a map projection versus a geodetic datum. Essentially, a geodetic datum provides accurate positions and heights. A map projection has no mechanism to provide geodetic control. Rather, a map projection simply arranges lines of latitude and longitude on a plane. For example, regardless of the map projection chosen to make a map, a point on the map with a latitude of 40°N will always represent 40°N. However, depending on the chosen geodetic datum, a point on Earth's surface (the center of the Washington Monument) will have different coordinate values. For example, Table 1 shows the various latitude values of Washington Monument according to three different geodetic datums.

TABLE 1. Latitude values for the Washington Monument, Washington D.C. (values obtained from NCAT)
WGS 1984 NAD 1927 NAD 1983(1986)

38.889484

(38° 53' 22.1424''N)

38.8893727401

(38° 53′ 21.74186″ N)

38.8894839194

(38° 53′ 22.14211″ N)

2.3. Grid Systems

Grid systems are Cartesian coordinate systems that are overlaid on top of an existing map projection. The purpose of a grid system is to simplify measurement tasks carried out on maps such as distance, angles, and direction. One of the more commonly used grid systems that provide worldwide coverage is the Universal Transverse Mercator or UTM. By carefully choosing a map projection and specifying the projection parameters, distortion throughout the mapped area can be minimized. This process leads to the employment of a suitable grid system that will result in achieving certain accuracy levels of measurement. Grid systems are usually associated with large scale mapping activities.  Thus, GIS users need to be familiar with the development of a grid system, the underlying distortion from the map projection, and how measurement accuracy can be assessed when using a grid system.

The course will be divided into 10 weeks. This course requires a minimum of 10-12 hours of student activity each week.

What will be expected of you?

Like any graduate-level course, you will be challenged to move beyond the knowledge and skills that you bring to the class. This is a three (3)-credit course, you should expect to be busy; as a rough estimate, you should allow at least 10-12 hours per week for class assignments. Included in the 10-12 hours each week is time to complete projects and related activities. The concepts in this class are challenging. Yes, there will be math involved. You'll be glad to know that you don't have to show up for class at a certain time! To avoid late penalties, you need to complete every assignment before the published deadline.

During the term, I encourage everyone to use the class discussion forums or email to help each other find relevant materials, learn about map projections, and complete each assignment. I can always be contacted via class email and will check my account daily during the week (and typically at least once each weekend). If I am traveling, I may check somewhat less frequently, but I will alert you of this beforehand.

My colleagues and I have worked hard to make this the most effective and convenient educational experience possible. How much and how well you learn is ultimately up to you. You will succeed if you are diligent about keeping up with the class schedule and if you take advantage of opportunities to communicate with me, as well as with your fellow students.

For a more detailed look at what will be covered in each lesson, as well as due dates for our assignments and activities, please refer to the semester-specific course schedule that is part of this syllabus (see "Course Schedule").


3. Course Goals

GEOG 861 will provide students with an understanding of the concepts, terminology, and processes that will be useful in manipulating and handling datums, map projections, and coordinate systems.

At the successful completion of this course, students should be able to:

  • learn the often complex terminology that is associated with geodetic datums, map projections, and grid systems
  • use that terminology to modify and adjust geodetic datum, map projection, and grid system parameters for specific mapping purpose outcomes
  • contrast the differences between a geometric and geopotential datum and the characteristics that define each
  • explain why a specific geodetic datum, map projection, and grid system was adopted for various mapping situations in the GIS environment
  • understand how to weave through the often complex GIS environment’s interface when specifying geodetic datum, map projection, and grid system parameters
  • understand what impacts will occur as map projection parameters and geodetic datum definitions are modified for a specific coordinate system
  • transform datasets from one geodetic datum to another geodetic datum
  • perform a coordinate conversion from one map projection into a different map projection
  • integrate disparate geodetic datums, map projections, and grid systems into a GIS environment, paying particular attention to the processes involved in aligning all datasets into a single coordinate system definition
  • explain the mathematical processes involved in coordinate conversions and geodetic datum transformations

    Educational objectives for each lesson are listed in the Course Schedule.

4. Required Course Materials

In order to take this course, you need to have the required course materials and an active Penn State Access Account user ID and password (used to access the online course resources). If you have any questions about obtaining or activating your Penn State Access Account, please contact the Outreach Helpdesk.

  • ArcGIS Pro: For many of the assignments, you will be using ArcGIS Pro. You should be running version 2.7 or later. If you need to upgrade to the latest version you should visit the Frequently Asked Questions for the GIS Certificate and MGIS Degree Programs.
  • Geocart: In addition to using ArcGIS Pro, you will use map projection software package called Geocart. You will need to acquire Geocart for this course. The software is available online at the Geocart website. There are two software options for you.
    • The "Demo" version offers the full capabilities needed for the lessons in this class. Of course, the benefit of this version is that it is free. We all like free stuff. The one issue you will have to put up with is the output will have a "Demo Version" watermark on all images.
    • If you would like to explore purchasing options, look under the Purchase tab. There are several different versions of Geocart. The "Limited Student" option is available for $100.00 USD. The main difference between the various versions is the included geographic databases. For our purposes in this class, you can select the Limited Student License that provides all of the map projection functionality found with the Professional License, but without the extensive geographic databases. You will use this software for a considerable portion of the course, and is designed to supplement map projection functionality that is not present with ArcGIS Pro’s coordinate systems tools.

Required Reading

Sickle, Jan Van. 2010. Basic GIS Coordinates. 3rd edition. Boca Raton, Florida: CRC Press (ISBN: 9781498774628).

This is the third edition of a very accessible text covering the fundamental topics covered in this class. Gives a very understandable perspective on the same topics covered in this class, using a minimal amount of mathematics. Highly recommended!

Recommended Readings

Note that the concept galleries used in this course are just that - they present the general concepts on the different course topics. Surprisingly, there are few books that cover all three of the course topics in any depth. I have listed my top ten references that I have read and thus recommend to further your understanding of these topics. They are presented in no particular order. 

1. Iliffe, Jonathan, and Lott, Roger. 2008. Datums and Map Projections for Remote Sensing, GIS, and Surveying. 2nd edition. Dunbeath Caithness, Scotland: Whittles Publishing (also available through CRC Press). (ISBN: 9781420070415).

While dated in its publication, this is a much improved second edition. The first edition was a bit muddy and thin, but the second edition is greatly improved and is also highly recommended as it adequately covers both datums and map projections. This text nicely dovetails the topical coverage of GEOG 861. This text balances mathematical treatments with discussions.

2. Meyer, Thomas. 2010. Introduction to Geometrical and Physical Geodesy: Foundations of Geomatics. ESRI Press, Redlands, CA (ISBN: 9781589482159).

This text presents the foundations of geodetic datums and map projections. There is ample detailed coverage in this text regarding physical geodesy (e.g., gravity, height, and tides) and how these elements are incorporated into vertical datums. This text is more mathematically inclined than the other books that follow - but don't let that scare you. This book has a lot of useful information that you will not find elsewhere in a convenient accessible place. There is a rather light treatment of map projections, and for that matter, the previous book on this list is recommended for that topic. 

3. Torge, Wolfgang and Müller, Jurgen. 2012. Geodesy. 4th edition. De Gruyter. Berlin. (ISBN: 9783110207187).

If you want to get deep into the mathematical "weeds" about geodesy, then this will be an informative book for your library. The intellectually dense text provides a substantial reading on physical geodesy with particular emphasis on gravity and how gravity defines Earth's shape and is consequentially integrated into GNSS. 

4. Lu, Zhiping, Qu, Yunying, and Qiao, Shubo. 2014. Geodesy: Introduction to Geodetic Datum and Geodetic Systems.  Springer (ISBN: 9783642412448).

A more recent text on geometric and geopotential datums. This text really dives into the mathematics of geodetic datums. Presents solid treatments of geometric and geopotential datums. 

5. Maher, Margaret. 2010. Lining up Data in ArcGIS: A Guide to Map Projections. 3rd edition. Redlands, California: ESRI Press (ISBN: 9781589485204).

This text explains in plain English how to manipulate coordinate systems in ArcGIS. This is not an in-depth discussion of map projections, datums, and grid systems. Rather, this text offers basic guidance on how to deal with the more common problems you are likely to encounter when dealing with datums, map projections, grid systems, and CAD files in ArcGIS Pro. For example, one of the common problems addressed in this text is that "my shapefiles don't align." Be cautioned that this is not a reference book intending to teach you about the above concepts. While there are some cursory explanations and discussions, the main focus of this text is to address ways to solve common coordinate system problems.

6. Flacke, Werner and Kraus, Birgit. 2005. Working with Projections and Datum Transformations in ArcGIS: Theory and Practical Examples. Norden, Germany: Points Verlag (ISBN: 3980846350).

This book is a bit dated (it applies to ArcMap version 8.x). However, this text is not for the novice; but if you have a reasonable understanding of datums, map projections, and coordinate systems and how ArcGIS Pro employs them, then this text will help build on your understanding considerably. Even though the text was designed for version 8.x, most of the coordinate system processes and concepts have changed little in ArcGIS Pro since its publication. If you do much in the way of programming and customization map projection processes, the closing chapters of this book will surely expand your horizons.

7. Snyder, John. 1987. Map Projections: A Working Manual. United States Geological Survey. Washington D.C. 

SImply, the bible on map projections. Includes derivation of dozens of map projections in both spherical and ellipsoidal forms. The appendix includes complete worked examples for every projection formula referenced in the book. Also includes a short narrative history of each projection. The entire book is available as a freely downloadable PDF. Has a short chapter on datums at the start of the text.

8. Hooijberg, Maarten. 2008. Geometrical Geodesy: Using Information and Computer Technology. Springer Berlin, Heidelberg (ISBN: 9783540254492).

The first half of the book is relevant to this course and provides a considerable range of topics dealing with geometric and geopotential datums. Chatper 3 provides a good read on how the figure of the Earth is defined. 

9. Kessler, Fritz. and Battersby, Sarah. 2019. Working with Projections: A Guide to their Selection.  CRC Press, Boca Raton, FL. (ISBN 9781138304987).

If you want to learn more about the rationale for selecting one projection over another, this book will help in that respect. The book breaks down spatial data into its component parts and cartographic symbolization methods, and then carefully aligns specific map projections with that data. As part of the discussion on selecting a map projection, the book considers how map readers' cognitive issues play a role in the choice of map projections. The appendix includes area, angular, linear scale, and overall distortion diagrams for dozens of map projections.

10. The journal Journal of Geodesy is a peer-reviewed publication focusing on various aspects of geodesy. Published since 1976, the journal includes a historical archive of articles that range from very complex mathematical treatments of geodesy topics to more digestible presentations.

Course Copyright

All course materials students receive or to which students have online access are protected by copyright laws. Students may use course materials and make copies for their own use as needed, but unauthorized distribution and/or uploading of materials without the instructor’s express permission is strictly prohibited. University Policy AD 40, the University Policy Recording of Classroom Activities and Note Taking Services addresses this issue. Students who engage in the unauthorized distribution of copyrighted materials may be held in violation of the University’s Code of Conduct, and/or liable under Federal and State laws.

For example, uploading completed labs, homework, or other assignments to any study site constitutes a violation of this policy.

Accommodations for Students with Disabilities

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Office for Student Disability Resources website provides contact information for Campus Disability Coordinators at every Penn State campus. For further information, please visit the Office for Student Disability Resources website.

In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled. You will participate in an intake interview and provide documentation. See documentation guidelines at Applying for Services from Student Disability Resources. If the documentation supports your request for reasonable accommodations, your campus’s disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early in your courses as possible. You must follow this process for every semester that you request accommodations.

Change in Normal Campus Operations

In case of weather-related delays or other emergency campus disruptions or closures at the University, this online course will proceed as planned. Your instructor will inform you if there are any extenuating circumstances regarding content or activity due dates in the course due to these delays or closures. If you are affected by a weather-related emergency, please contact your instructor at the earliest possible time to make special arrangements.

Reporting Educational Equity Concerns

Penn State takes great pride in fostering a diverse and inclusive environment for students, faculty, and staff. Acts of intolerance, discrimination, or harassment due to age, ancestry, color, disability, gender, gender identity, national origin, race, religious belief, sexual orientation, or veteran status are not tolerated (Policy AD29 Statement on Intolerance) and can be reported through Educational Equity via Report Bias.

Counseling and Psychological Services

Many students at Penn State face personal challenges or have psychological needs that may interfere with their academic progress, social development, or emotional well-being.  The university offers a variety of confidential services to help you through difficult times, including individual and group counseling, crisis intervention, consultations, online chats, and mental health screenings.  These services are provided by staff who welcome all students and embrace a philosophy respectful of clients’ cultural and religious backgrounds, and sensitive to differences in race, ability, gender identity, and sexual orientation.  Services include the following:

Counseling and Psychological Services at University Park  (CAPS): 814-863-0395
Counseling Services at Commonwealth Campuses
Penn State Crisis Line (24 hours/7 days/week): 877-229-6400
Crisis Text Line (24 hours/7 days/week): Text LIONS to 741741

Military Personnel

Veterans and currently serving military personnel and/or spouses with unique circumstances (e.g., upcoming deployments, drill/duty requirements, disabilities, VA appointments, etc.) are welcome and encouraged to communicate these, in advance if possible, to the instructor in the case that special arrangements need to be made.

Connect Online with Caution

Penn State is committed to educational access for all. Our students come from all walks of life and have diverse life experiences. As with any other online community, the lack of physical interaction in an online classroom can create a false sense of anonymity and security. While one can make new friends online, digital relationships can also be misleading. Good judgment and decision-making are critical when choosing to disclose personal information to others whom you do not know.

Deferred Grades

If you are prevented from completing this course within the prescribed amount of time for reasons that are beyond your control, it is possible to have the grade deferred with the concurrence of the instructor, following Penn State Deferred Grade Policy 48-40. To seek a deferred grade, you must submit a written request (by e-mail or U.S. post) to the instructor describing the reason(s) for the request. Non-emergency permission for filing a deferred grade must be requested before the beginning of the final examination period.  It is up to the instructor to determine whether or not you will be permitted to receive a deferred grade. If permission is granted, you will work with the instructor to establish a communication plan and a clear schedule for completion within policy.  If, for any reason, the coursework for the deferred grade is not complete by the assigned time, a grade of "F" will be automatically entered on your transcript.

Attendance

This course will be conducted entirely online. There will be no set class meeting times, but you will be required to complete weekly assignments with specific due dates. Many of the assignments are open for multiple days, so it is your responsibility to complete the work early if you plan to travel or participate in national holidays, religious observances or University approved activities.

If you need to request an exception due to a personal or medical emergency, contact the instructor directly as soon as you are able. Such requests will be considered on a case-by-case basis.

Diversity, Inclusion, and Respect

Penn State is “committed to creating an educational environment which is free from intolerance directed toward individuals or groups and strives to create and maintain an environment that fosters respect for others” as stated in Policy AD29 Statement on Intolerance. All members of this class are expected to contribute to a respectful, welcoming, and inclusive environment and to interact with civility.
