Using Google Fusion Wizard, I was able to combine the point layer of the schools and the polygon layer of the watershed together. I will have to play around with the colors of the points as well as the watershed for my final map. I would also like to be able to show the schools in the watershed alone and take out the other schools. But the map below is starting to look more to how I would like my final map to look like.
Now that I can add layers to point maps, I would like to add more to my final map. For example, it would be nice to include boundary lines of the municipalities, parks/nature centers/libraries, impaired water systems, etc. My next step is to search for other shape files with the above details in either the Trinity GIS folders or by downloading them.
