Map Suite WebAPI Edition supports multiple ways of how to query your map data layers. In this learning sample we will discuss some of the various querying tools.

Allows you to take one feature and see how they interrelate with other features. There are several different types of spatial querying: within, contains, disjoint, intersects, overlaps, and touching.

Another popular type of query in GIS applications is to query by distance. In this example we show you how to return countries within a given distance from a point.

This sample shows inner relation between tabular or feature data associated with each shape. In this sample we show a grid representation of each country in the world. When clicking on the result users are zoomed in to that specific country. This can be very helpful if you are using a data grid and want to be data driven or vice versa.

Users can also click on the map to find all features associated with what was clicked on. In this example we click on Brazil which returns all the attribute data associated with Brazil. This sample shows you how to use the map click event and how to query through the API.

This sample we use the power of SQL which allows users to write custom queries against their data sources. In this example we wrote a SQL query to return any countries that are landlocked. For the result we highlight each country that meets the criteria. This is another great way on how you can use the various querying APIs to analyze your data.
