Spring Break Lab

This lab was fairly easy. It took longer than it should have because of the server.

Week 9

Q1: I used the intersect tool. The output was exactly the same as the union tool's output.

Q2: I used the erase tool because I needed to exclude (erase) the conservation areas from the buffers union layer.

Q3: There are 79 features. Largest: 7765034.49 Sq. Meters, Smallest: 748.11 Sq. Meters

Week 7

I made this assignment harder than it was. For some reason forgot pretty much every step in digitizing, so I had to go back to the ESRI site and read the lessons over again.

Week 6

This map shows two UWF raster images that were georeferenced according to the roads and building layers. I did not have any problems with the lab until the end when I needed to clip off the roads and buildings that were outside the raster image. I ended up deleting them with the editing tool. The line dividing the two images is quite obvious. I don't know how to fix that without messing something else up in the process!

This map shows the DEM, DOQQ and DRG raster files for three Putnam county quadrangles. This map is projected in Transverse Mercator except for the DEM raster. It is "on-the-fly." I made many attempts to get this file to project correctly. It never worked. I probably spent 20 hours trying to get this thing right!

This map of Putnam county shows the major land cover, and invasive plant species. I encountered no problems with making this map. It took a long time to make because it was very slow in loading each layer. The projected coordinate system I used was Albers Conical Equal Area.

Here is the first map of my assigned county. This map displays public parks, major highways, hydrology, and cities of Putnam county, Forida. Finding data for this map was not too hard. I did find a couple data layers that had errors in them, I believe. The only other problem I had was the amount of time it took. Sometimes clipping took 15+ minutes. Then when I cancelled the clipping, the program froze up and I lost everything I did not save. I think certain times of the day (around 8 pm specifically) more people are using the network and it is much slower than usual. Today I had no problems with the speed of the program. The Projected coordinate system I used was Albers Conical Equal Area.
