When a location is successfully searched, it returns the following data:
We can use this data to show us where we get the information.
Based on these understandings, we have made our routines: main.qml

Before we can use the map software is very few, and a map package easily hundreds of M, also does not support GPS, no real-time road conditions, no satellite map, a year may not be updated once. Now the map function has been greatly enriched, the developer's project selectivity is also very large, the map which audience more useful? Developers do not do "Outman" to keep your project up to date with the times! Dev brings you to know.

Desktop Users implementing a distributed GIS: ArcGIS Desktop users can use arcgisdesktop applications (such as ArcMap or arccatalog) to connect to ArcGIS Server, and execute GIS server objects in ArcGIS Server for jobs, arcGIS Server allows them to scatter GIS processing programs (such as geocoding, map rendering, or geographic data processing ). ArcGIS Desktop Users can connect to ArcGIS Server in the local network and directly use GIS server object

The previous section briefly introduces how to obtain user locations and use longitude and latitude to represent locations. This section describes geographical encoding.
First, we need to know what is geocode
Concept:
Geographic code: it refers to the process of establishing the spatial coordinate relationship between statistical data or address information. It is called geographic code. c
