SuperGeo Technologies will release SuperPad 3.0 Beta in April of 2009. SuperPad 3.0 is developed by the brand new operating core-SuperGIS Mobile Engine 3.0, which features with more powerful functions, speedy operation and more user-friendly manipulation. Moreover, users are also able to develop their own plug-in extensions, such as the self-defined layer format, symbols, GPS Protocol or toolbar buttons with SuperPad 3.0. Therefore, SuperPad3, providing a wider application and more flexibility for function usage, can be seen as the best choice of the mobile GIS software.
