Locating GPS Coordinates on PDA

摘要

The purpose of our research is to find algorithms for loading large maps on PDA and place on them the geographical location given by latitude and longitude. C++ and C# programming languages have been used for implementation. It was elaborated a software which runs on PDA with Windows Mobile 2003 OS and implements algorithms for finding the coordinate on a map represented like a TIF image. The application must localize the coordinates known by longitude and latitude over a given image in TIF format which can represent a map with scale 1:200000 or 1:25000. The map headers contain information that refer to map limit. An algorithm that permits map synchronization when the value of current map is out of limit it was necessary.
