Adding GIS to your apps with ArcGIS APIs
Guest post by Accadius Sabwa
On a daily basis, the average internet user accesses location based services at least once. This means that location based services are becoming important by the day in this “connected” lifestyle. Every now and then, you open a webpage and you see where an event is, where a building is, where an institution is on a map. Smartphones and tablets are becoming popular by the day, partly because of their ability to help us find the nearest place to have coffee or give you directions then navigate you to a place you don’t know. Have you ever taken a minute to imagine what goes on behind the map before it returns you position or draws you that route? All that is powered by a concept known GIS (Geographical information systems).
Ever wanted to build an application with location capabilities? Or include locational capabilities in your existing app? Here’s how.
As a developer, there are a number of API’s which can help you achieve this.
Let’s focus on ArcGIS open API’s as we attempt to put paper based and non-interactive maps behind us. They are mainly classified into the following categories.
These APIs helps you to build and embed interactive maps in your website. You can harness online services, GeoRSS and social media feeds, and tools and widgets to create custom web maps
The available web API’s are:
These APIs help you build easy to use applications that run on GPS enabled mobile gadgets that can:
- Display and navigate maps
- Find addresses and places
- Identify Locations and GIS features
- Query map layers and data
- Measure lines and areas
These APIs help you to create stand-alone apps to meets specific needs of a client.
In addition to the free and open API’s you get two additional features
