I have a question on the way Maemo Mapper calculates the speed displayed in the upper left corner. I remember seeing a post that Maemo Mapper does not consider altitude in its calculations. I assume this means that speed is calculated for horizontal distances between gps readings. Does this mean that the speed Maemo Mapper reports when traveling on an incline is less than actual speed due to the angle? I travel in mountainous areas and was curious, not that there is any problem.

Thanks
