Where To Look for Data

One of the initial stumbling blocks for Community Health Mappers post-workshop, is where to look for data. There is a lot of data available online. Most municipalities, counties and states will have some sort of GIS data portal. These are sites where publicly available mapping data can be downloaded and are best found with an internet search. Those are simply too numerous to list. However, the list below is a good starting point for commonly used national GIS datasets.
