Morgan's GIS Maps

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.

In projections part 2 we learned the difference between defining a projection and actually re-projecting a projection. I gathered quads from the labin's website and those I had to define the projection because when I looked in the ArcCatalog they had no existing spatial information. When obtaining county boundaries and major roads those files had to be re-projected as they already had a defined projection. My projections came out all in the specified coordinates but end map could have used a little more work.

In this week's lab exercise we learned about different coordinate projections and how to choose the most appropriate one to display the area we want to highlight most accurately. We created three different maps with a table showing county comparison by area in square miles.

This week we created map packages for sharing as well as troubleshoot errors that may arise. The information provided went more extensively into spatial reference and appropriate situation to use them as far as the area of the earth you may be working with. I created a Top 10 list of water-based Florida State Parks based on a  web sites criteria (I have not visited them all to be able to rank them) and provided url links to them all. I input all of the information into a excel spread sheet that could then be used in other applications. I developed the map a little further in both ArcGIS and ArcMap.
