This is a great 3D GIS (Geographic Information System) data file viewer. It supports the most popular spatial data formats including ESRI shapefile (shp and shx) and AutoDesk dxf. They are native formats for ArcGIS (ArcEdit, ArcView, etc.) and AutoCAD. Even if you are using GIS systems which don't directly use SHP or DXF file, for instance, MapInfo, it is not difficult to convert your data model into either shp or dxf format. With help of this app, you can take your GIS data files with you no matter where you are, at home or traveling abroad, and view them with your phone (or tablet) in any way you want.The app provides many 3D features including rotating model with finger movement, zooming in/out, changing color, etc. You can also load multiple files together.Data files can be added to the app's external storage folder called 'afanche'. Just connect your phone (or tablet) with a PC and copy your 3D models to the 'afanche' folder of the device. After that, you can use the app to load the models you saved in the directory. If you have files in system 'download' folder or any other folder of your device, you can use the app to find and open them as well.
