Week 9-Vector Analysis II

Lab 9-Potential Campground Sites

I thought this was a fun and interesting Lab.  It seemed that the operations of buffering and overlay have a lot of "real world" applications and it was educational learning the sequence to perform these tasks.  I had a few stumbles along the way but doing it a few times and a few different ways promoted more (hopefully!) understanding. 

Q1:  Which tool did you use? Was there any noticeable difference between it's results and the results from the instructions?

I used the intersect tool.  I did not notice any difference between its results and the results from using the union tool for this example.

Q2:  Which tool did you use here?  Why?

I used the Erase tool.  The erase tool was used to create a new feature class by removing portions of the buffer areas that were overlapped by the conservation areas.

Q3:  How many features are in this layer?  What is the area of the largest feature?  What is the area of the smallest feature? 

I counted 79 features in this layer.  The largest area polygon is 776,503 square meters.  The smallest area polygon is 748 square meters.

Spring Break Lab

Gulf County Largest Parcel Owners

I thought this was an interesting exercise.  After computing the data, I was sure I didn't do it correctly, as it said the St. Joseph Land & Dev. Co had 198,000 acres.  After reviewing some other Gulf County statistics, I saw that they did indeed own about 80% of the county.  The last two exercises has shown me the power of joining.  I also learned about the "create a layer from current selection".  Great tools.

Lab 7-Data Editing

Lab 7-Data Editing

I found that one of the buildings with a blue dot was not present in my data set so I went ahead and digitzed it. I had to refer back to the keystoke sequences in the ESRI-Module 5 exercise.  I obviously would need to have a lot more practice with this module to feel comfortable, but I think I got some of the basics.
