Hike

Hike is an open-source GPS Maemo application for Nokia N800/N810 internet tablet. Its purpose is to display the picture of a paper map and your GPS position on top of it. It's a useful alternative to more ambitious navigation GPS applications where good digital maps aren't readily available, such as hiking paths or exotic places.

The picture of the map is obtained typically with a digital camera. Choose a large focal length and have the map perpendicular to the view direction, so that parallel lines on the map remain parallel on its picture. Choose a low JPEG quality to have a file not too large (a few hundred kilobytes are fine, more could force you to quit other applications). Rotations and scale discrepancies along x and y axis are taken care of.

The position mapping from GPS (latitude/longitude) to picture is based on at least two "calibration points". If you know the latitude and longitude of points which can be specified on the map picture, you can enter them numerically in decimal degrees or degree/minute/second; otherwise, you can use your GPS position as you walk. Calibration points should define an area as broad as possible.

Features overview

Hike has the following features:

• Can load any jpeg or png image
• Stores calibration points in a file with a .cal suffix associated with the image file
• Remembers the last map image and loads it at startup
• Displays the GPS position and altitude, in normal view or full screen mode
• Choice between metric and imperial units, and decimal or deg/min/sec angles
• Can record tracks where fluctuations are smoothed out and save them in GPX format
• Detailed GPS information with estimated position uncertainties
