Can you create a nice looking map in layout and print it out? Can you define, project and reproject data? Can you incorporate raster and vector data in a GIS exercise? Can you perform a slope analysis using spatial analyst? Can you create a hill-shading model using spatial analyst? Can you create vector and raster-based queries to identify select areas on a map? Can you add data to a table using the table editor? Can you use the geoprocessing to clip, dissolve, merge data? Can you find and download gis data from web sites, convert and decompress the data? Can you use the editing tools to create and edit polygons? Can you employ heads-up digitizing to create your own shape files? Can you use image analyst to mosaic air photos? Can you use a photo / image base and create a shape file via digitizing? Do you know what the following files / data types are: *.e00, *.shp, *.grd, Mr. Sid, *.tif, *.jpg, *.tfw, *.sdw, *.zip, *.tar.z, DOQ, DRG, DEM Can you download and import a USGS DEM into an arcview / spatial analyst grid format? What’s the difference between an *.dem and *.grd file format? Can you manage *.zip and *.tar.gz files? Do you understand basic concepts of map algebra and what types of data it’s used on? Anticipate: 2-3 essay questions focusing on broad summaries of GIS, the types of applications it may be used for, the components of ArcMap specifically. GOAL OF FINAL EXAM: To test your ability to use
