Go outside on a mapping expedition! Turn your Palm or Visor into a portable surveying instrument with the power of a computer. How high is that tree, mountain, building? How high did the model rocket fly? How far is it across the river, lake, canyon? What's the distance between those places on opposite sides of that hill? Does the altitude and azimuth of that star match the altitude given for Vega in a planetarium program? All of these can be done in the field. 

Export the data records to memos in CSV format and input them into a PC spreadsheet such as Microsoft Excel.  Use the data with a protractor and ruler to create maps on your own of the areas. Participate or compete in fun and educational activities in cartography. 

Expedition ES requires only a string to take altitude and azimuth measurements (remember the old protractor altitude finder in school?). The altitude is the vertical angle from your present position to the top of another object or waypoint. The azimuth is the horizontal angle between a waypoint and another reference waypoint, taken from your present position. A loop at one end of the string can hold the stylus (or keys, etc.) for weighting for altitude. The other end can either be held against the left edge with a finger, or for convenience it can be taped and the pivot point calibrated. A waypoint/object is aligned with an edge of the device or display. After the string lies at the vertical or horizontal angle, the string is held and then pressed against the display to compute the angle. Sighting edges can be selected for up/down altitudes and 360-degree azimuths, and multiple data records are averaged for the internal calculations. 

Expedition ES provides the following features: 

• Up to 32 user-named mapping waypoints.
• Altitude measurements between waypoints.
• Azimuth measurements between waypoints.
• Distance entries between waypoints.
• Data record management. Data export in CSV format.
• Height calculations of objects based on data records. Scaled graphical display of results. User-defined measurement height automatically added.
• Distance calculations of inaccessible waypoints based on data records (Registered Version). Scaled graphical display of triangulation with layers.
• Entries and graphical displays in English and metric units. User-defined Step lengths.
• Altitude and Azimuth measurements taken either with a loose string or with a string taped at a calibrated pivot point.
• Written in Quartus Forth--compact, fast!
• Detailed user manual with engaging activities.
• Reasonable cost for Registered Version ($5)
