The lesson addresses the two highlighted elements of the Structured Geospatial Analytic Method (SGAM):
The question, or analytical problem, should be viewed as an active two-way interface between the client requiring the information and the geospatial analyst supplying it. For effective analysis to occur, an intelligence question must be “analytic” which means four conditions are met:
- There must be at least one thing which needs to be explained.
- At least one plausible explanation must be posed.
- Counter-explanations are possible and analysis must include an investigation of alternative hypotheses.
- The hypotheses must be well-defined enough to allow us to gather evidence.
Before addressing the question, the analyst must have a base of knowledge. When dealing with a new and unfamiliar subject, the uncritical and relatively non-selective accumulation and review of geospatial information is an appropriate first step. This is a process of absorbing geospatial information, not analyzing it.
At the end of this lesson you will be able to:
- Identify a suitable analytic question.
- Evaluate the suitably of data and information available to the analyst.
The Course Roadmap is intended to help you understand where we are in the overall learning process and to place our dual case study and project focus into context.
The Course Roadmap highlights where students are within the course. For Lesson 4, read/skim the materials that are presented, and then participate in a dicussion forum regarding the quality of information of the DC Sniper materials.
Lesson 4 is one week in length. (See the Calendar in Canvas for specific due dates.) To finish this lesson, you must complete the activities listed below. You may find it useful to print this page out first so that you can follow along with the directions.
