| - | In this sample, we are going to show you a popular way to query with the mapping and GIS application is by distance. We can get all features it was in giving distance of giving point. Usually, you can use other features such as polygons airlines to distance careers as well. | + | 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. |

| - | In this sample, we are showing how query all features data, here we are showing a grid representation of all the countries of the world, and if we click on one of these magnifier we can actually zoom into that country. | + | 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. |

| - | In this sample we are going to show you how query feature by click on the map. at the same time we get the data of feature by your clicked. | + | 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. |

| - | In this sample, we unlocked allow the power of SQL to allow you to write custom queries against your data sources. So here we wrote a SQL query to return any countries that are landlocked and when that we have API is with the Map Suite at I’d executed SQL return any results. And here we are highlighting those countries on the map. | + | 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. |
