Description:

Map-tools software is a set of tools associated with Google Maps and also a coordinate converter. We can get mesurements (distance, length, area, altitude) , drawing with export to DXF or text files, import Text, DXF, KML files, display WGS84 (used by GPS system) coordinates and converted in the chosen coordinate system, for example: UTM, Lambert, RGF93, NAD83, NAD27, Mercator....

Legend:

X et Y : Plane projection coordinates;
h : ellipsoid height;
Long : Longitude;
Lat : Latitude;
dms : Degree Minute Secondes.


Instructions:

  • For GPS coordinates, select the WGS84 system.

  • To convert the angle unit of geographical coordinates Latitude-longitude (degree, minute seconds (dms), grad, radians), just use the angle units converter .

  • To be located, press ‘My location’ button.(the accuracy depends on the available positioning system)

  • To view the terrain, press the Map option, and then check Terrain.

  • To suggest other coordinate system, post message on the site's forum .

  • To calculate the length between 2 points, use the length command Distance and click on 2 points directly or on markers.

  • To calculate the length of a path, use the polyline command Polyligne to draw a polyline by clicking points directly or markers; after, press the validate button Polyligne or Polyligne or right-click over the object to terminate command; and click the polyline to display its length.
  • To calculate the area of a parcel, land or building; use the polygon command Polygone to draw a polygon by clicking points directly or markers; after, press the validate button Polyligne or Polyligne or right-click over;  and click on the polygon to display its area.

  • To removea polygon or a polyline, press delete button Polyligneand click on the object.

  • For your questions, comments and suggestions go to the site's forum .
