Work through chapters 15 and 16 in the green book. They will go through the whole digitizing/editing/attributing process.
Finally, let's do a little digitizing exercise. Start by opening ArcMap and loading a couple of airphotos from the county. The photos can be found in the geog303\digitizing\ subdirectory. They are a couple of photos of Cle Elum. They aren't the highest quality, but they'll have to do. They are projected in NAD83, WA state plane south, feet. Be sure the photos are adjacent to each other - they are named based upon quad sheets. NOTE: while the files are projected, they are undefined. As always, copy the airphotos you want to your own drive before working!!!
Now, drop into ArcCatalog and make three blank shapefiles. File - new - shapefile. Make one a point file, one a line, and the third a polygon; name them appropriately and be sure to set the projection info to the same as the airphotos.
Load these three files into your ArcMap window and start a edit session.
Your job is to put data into the three shapefiles. For the polygon file, digitize a bunch (at least 15) of adjacent property polygons (take your best guess, taxes won't be based on these). Make sure the polygons are created by snapping them together as you did in the green book. For the line file, digitize the roads near your properties (at least 15 roads). For the point file, digitize the trees within your polygons (as many as there are. If there are no trees present, place 6 fantasty trees and note on your map that these are hallucinated. Finally, produce a final map that includes not only the base airphoto, but a title, legend, north arrow, your name, neatline, and your three data layers [point, line, and polygon]. Get this to Kristen for a final color print (as a pdf file).
Due date: 9 november. Worth 3 points.
