Restoring OpenStreetMapLayer Functionality in ThinkGeo UI

Are you using the ThinkGeo UI OpenStreetMapLayer in your application and experiencing problems with map tiles not loading? This may be due to recent changes on OpenStreetMap’s side in which they are more strictly enforcing their Tile Usage Policy. This policy requires (among other things) that any application consuming tiles from OpenStreetMap’s servers must identify itself with a valid HTTP User-Agent. By default, ThinkGeo’s OpenStreetMapLayer does not specify a User-Agent, but you can (and should) set one yourself.

No matter which edition of ThinkGeo UI you are using, you can specify your own User-Agent on each tile request by handling the OpenStreetMapLayer’s SendingWebRequest event. Continue reading

Map Suite Supports 3D Buildings

Do you have shapefiles with building height information or have an application in which you’d like to display building heights? Map Suite now offers new APIs that allows developers to display elevation information from shapefiles as well as the OpenStreetMap (OSM) Building data across mobile, web, and desktop apps. This can help developers make their maps more visually appealing depending on the application. New samples available via GitHub have been prepared to help you get started quickly:

Mobile:
Display 3D buildings using shapefile on Android (GitHub Sample)
Display 3D buildings using shapefile on iOS (GitHub Sample)

Desktop
Display OSM Buildings using WPF (GitHub Sample)
Display 3D buildings using shapefile on WPF (GitHub Sample)
Display 3D buildings using shapefile on WinForms (GitHub Sample)

Web
Display OSM Buildings using WebAPI (GitHub Sample)

Map Suite UI controls enables developers to build amazing GIS and mapping applications across the web, desktop and mobile platforms. Continue reading

Using OpenStreetMap Data in Your Application

When it comes to GIS one of the biggest hurdles usually involves mapping data. Data comes in many forms, formats, licensing options from a variety of providers. Premium providers can be cost prohibitive and have strict licensing policies. The good news is the growth of OpenStreetMap.

In case you aren’t familiar with OpenStreetMap, it’s a giant crowd-sourced database of free geographic data built by users all around the world. You can even add or correct data in OpenStreetMap yourself — and if you do, it will appear on OpenStreetMap as well as under ThinkGeo’s World Map Kit Online within a couple of hours.
