spatial query

In many of our other articles and resources about geographic information systems (GIS) and mapping for nonprofit organizations (NPOs), we focus more on the "NPO" than the "GIS" aspects: why should NPOs use GIS/mapping tools, how do these tools help fulfill nonprofit missions, when is it appropriate for NPOs to use these tools, what types of projects are other NPOs working on, etc.

In this article I'll be discussing some concepts squarely from the GIS/mapping side of the fence, but relax: we're going to keep it super simple and try to put in as many relevant community/NPO/NGO examples as we can :)
