Study Guide for Final Exam

The following are just guidelines. The final exam may or may not have questions related the following items and is not limited to this list.

The final will follow the same format as the mid-term. Short answer questions for the most part. The exam is comprehensive, covering material from before and after the mid-term.

Here is a bulleted list of items from the material after the mid-term, including material that was covered before and after the mid-term:

Topographic analysis

• Elevation and elevation derived surface
• How slope and aspect are calculated
• Implications of cellsize with elevation, slope, aspect
• Source of DEM raster data: air photo, stereo pairs, contour lines, raster grid

Scale - this is a big one...

• Implications of scale for data analysis
• cellsize, scale of vector source data (e.g. the coastline example)
• scale, cellsize and data overlay/data integration

Grid manipulations

• Grid algebra, focal functions, zonal functions
• Topographic analysis

Data Transformations

• point to polygon (buffers, thiessen polygons)
• line to polygon

Data Integration

• Data overlay, vector overlay vs. raster overlay
• Land use/landcover change

GPS and GIS/RS Integration

• Error associated with GPS point locations
• Implications of overlaying GPS point data with raster data of different cell sizes
• Cell size and satellite data

Error

• Underlying all these concepts are questions of spatial and attribute error
• Thinking about the sources of error in spatial manipulations helps you understand the underlying concepts and is important for understanding the limitations of data and analysis
• Several times in class we discussed sources of error with different operations, the final exam will go through these same types of exercises
