Abstract

The purpose of our research is to find algorithms for loading large maps on PDA and place on it 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 refers to map limit. An algorithm that permits map synchronization when the value of current map is out of limit it was necessary.
