Lab 10 (SB Assignment)


The lab went quite well up until I tried to import some road and water shapefiles from Tiger Census information. The layers wouldn't align with the parcel data even after reprojecting them to match projection/coorindate systems with the parcel data. I'm not sure why this kept happening, so I left those layers out of the map. Besides the projection issues (if thats what it was), everything went smoothly.

Week 9 Post


Q1: Which tool did you use? Was there any noticeable difference between its results and the results from the instruction? I tried using the intersect tool. It seemed to work in the exact same way. It combined the features that overlayed the same areas, and it also included the same options for dissolving, joining attributes, etc.. I did not notice any difference between the two results.

Q2: Which tool did you use here? Why? I used the 'erase' tool. It simply cut out the area of the buffers that were overlaying the conservation areas. I used this tool due to its simplicity and efficiency.

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 found 79 features in this layer. Largest area: 7765034 Smallest area: 748
