For example, let’s say you want to find the number of gas stations that are within a given distance from your location. Distance querying can help you answer such questions.

Map Suite offers a couple different Distance Query APIs to help you build your application including:

• GetFeaturesNearestTo – finds the nearest feature from your location. Continue reading
