Week 9 Vector Analysis II

The lab was to create buffer polygons based on criteria using 3 different polygon layers, then determine where these buffer areas intersected. We created areas for potential campsites that were within 300 meters of existing roadways, within 150 meters of lakes, and within 500 meters of rivers. We were also asked to exclude areas that were considered conservation areas. The answers to the following questions:

1, I used the intersect tool - intersecting the road buffer and the water buffer files. I did not find any difference between the two.

2. I used the erase tool to exclude areas that fell into the conservation areas since as campgrounds could not fall into those areas.

3. I ended up with 79 separate polygons. Acreage of the largest feature was 1918.77, acreage of the smallest feature was 0.18.

Extra Credit GIS 4043

The extra credit exercise we were given involved bringing in data and joining to our attribute table as a way of analysizing outside data within GIS. We were to locate and symbolize the four largest landowners in Gulf County, Florida. This was done with data from the Florida Department of Revenue. In order to join tables with a shapefile - you need to have some common field. The field names do not need to be identical but they do need to hold the same data. This was a fun and quick exercise.

Week 7 Data Editing

We created an ArcMap. We created a new shapefile. We digitized features from aerial photos - creating, correcting, and snapping.
