In our first week we were asked to create a map using basic GIS tools and views. We added data in ArcMap and used tools to create a map showing countries by population:
This week we used and learned about buffering, overlay, and union of vector and raster data. We also learned to write script in arcpy-It took me a couple of errors before I got it completely right but it is a very useful tool if you have multiple items that need to be ran because for one being able to copy and paste and being able to adjust little bits of information in the script. Though we just learned the basics of buffer and overlay I look forward to delving deeper into the capability of these tools.
This week in data search we were to collect our own data and project it into a single projection to be used in a map. I was assigned Nassau County and collected a DOQQ (the NE region) a DEM and five vector layers to be used. I chose to re-project layers into the same projection changing the "03" designation of North into "01" East as that was the quadrant I was using. I ran into some problems with some layers showing through and finding land that was not township range in the data base provided but for the lack of time had to submit what I had.
