Helpful Online Mapping Software
The city of KCMO and Johnson County, Kansas, both have great online mapping software. I use them often to measure lot sizes, and see a visual representation of the shape of a lot. Plus, it tells you who owns the property. These mapping sites can do much more than that, like show you school districts, parks, trails, and utilities. I keep these web addressed bookmarked for when I need them because I can never seem to find them easily.
