Lesson Data

This section provides links to download the Lesson 7 data along with reference information about each dataset (metadata). Briefly review the information below so you have a general idea of the data we will use in this lesson.

Lesson 7 Data Download:

Note: You should not complete this activity until you have read through all of the pages in Lesson 7. See the Lesson 7 Checklist for further information.

Create a new folder in your GEOG487 folder called "Lesson7." Download a zip file of the Lesson 7 Data and save it in your "Lesson7" folder. Extract the zip file and view the contents. Information about all datasets used in the lesson is provided below:


Publicly Available Data:

Base Map:

  • Source: Esri Resource Center (see Lesson 2 for more details about this site)
  • Service Names: Imagery Hybrid
  • Within ArcGIS, go to the Map tab within the Layer group and click on the Basemap (select Imagery Hybrid from dropdown menu).

Private Data (Located Inside the Lesson7 Data Folder):

The starting data for this lesson is contained in a geodatabase called Lesson7.gdb. Geodatabases are a convenient way to keep all of your project data organized in one place. You may want to read about geodatabases in the online help provided by Esri if you are not familiar with this data format.

  • Study_Boundary: The study site is located in Southeastern Cameroon. It encompasses land management units designated for conservation and logging.
  • Roads07: Road centerlines digitized from 2007 Landsat images.
  • Roads01: Road centerlines digitized from 2001 Landsat images.

The roads and study boundary were created by customizing portions of the "Interactive Forestry Atlas of Cameroon" for our study area. The original data was created by the World Resources Institute - Global Forest Watch (GWF), a nongovernmental organization (NGO) focused on environmental issues. They regularly produce reports and data about the state of forests and logging in Central Africa (among other locations). Part of their work involves the creation of GIS datasets to assist forest managers.
