For my project at work, I am trying to compare and contrast property information with points I have mapped (from my workplace)
Example: I have points with information on water samples, the results of their chemical testing, well depth and date sampled.
I have tax parcel polygons for each county (U.S.) and that table can tell me whether that property has a private or public well
I'm interested in finding what points are on properties that have a private or public well, or no well.
I was thinking of trying to make a thematic map for each, but it gets confusing fast. I was thinking of applying X color for private wells, Y color for public supply, and Z for none or other. After that, I was going to apply a range of low to high levels of toxicity for the chemical our workplace is investigating, that has 4 different colors.
Is there a less complicated way of comparing/contrasting polygon information with point information in two separate tables that can't be joined?
I am new to MapInfo, and have not had an easy time finding guidance on how to interact with the software. This is my first GIS software program that I've jumped into using, with just a few hours of training and a lot of trial and error.
