Lab 12: Vector Overlay and Geoprocessing1. Refresh the concepts learned in class reading Chapter 10 from \u201cMastering ArcGIS\u201d by Maribeth Price.<\/p>\n
2. Work through the Teaching Tutorial (up step 40) to learn how to do the different overlay operations, buffers. The sections on \u201cWorking with slivers\u201d and \u201cGeoprocessing with Model Builder\u201d are optional but highly recommended. Model builder is similar to the Macro Modeler within IDRISI and facilitates the analysis within ArcGIS.<\/p>\n
3. Do the Exercises section and answer the 10 questions (1 point each).<\/p>\n
1. The Madison Limestone is an important aquifer. Citizens are concerned about gas or chemical
\ntrucks overturning on roads and causing contamination. What is the total length of roads
\ncrossing the Madison, in kilometers
\n2. The infiltration rate of the geological substrate is a strong factor in evaluating the spill hazards
\nfor roads. Create a map of all the roads based on the infiltration capacity of the geology, using
\nappropriate symbols to indicate hazard. Capture your map.
\n3. The use of a road is another factor in evaluating spill hazards. Create a new field in the roads
\nfeature class with a hazard rating of 3 for primary roads, 2 for secondary roads, and 1 for
\nprimitive roads. Create a map and capture it.
\n4. Now create new field for a hazard index based on both infiltration and use, adding them
\ntogether. What is the range of values for the index Create a map of the roads based on the
\nhazard index. Capture the map.
\n5. Rangeland can cause significant impacts on surface water quality. Using the lulc and
\nwsheds2b feature classes, create a table showing the area of rangeland in each watershed.
\n(Include both herbaceous and mixed rangeland categories.)
\n6. Areas that are within 300 meters of both streams and primitive roads are the most popular
\nplaces for fishing. Create a map showing these areas. Capture your map.
\n7. The fishing areas in #6 should be restricted to areas within the national forest (OWNER =
\n\u2018NFS\u2019 in the vegetation feature class). Create a revised map showing the public access fishing
\nareas in green and the private fishing areas in red. Capture your map.
\n8. You need a feature class that shows polygons based only on infiltration and only within the
\nwshds2b area. Symbolize this layer based on infiltration. Capture your map.
\n9. The Forest Service is concerned about septic systems contaminating the Madison Limestone.
\nCreate a map showing private land (OWNER = PVT in the Vegetation layer) on the Madison.
\nCapture the map.
\n10. The Forest Service is considering adopting a policy to not cut timber within 200 meters of a
\nprimary road (TYPE = P). Assuming that cutting timber includes all SSTAGE96 LIKE \u20184*\u2019,
\ndetermine the total area in square kilometers lost to harvesting if this policy were adopted.
\nCapture a map showing the off-limits areas
\n4. Optional: Solve the Challenge Problem. Do it just for fun or if you need a reward, 0.5 points will be added to your lowest lab.<\/p>\n","protected":false},"excerpt":{"rendered":"
