If the points in the GPS are a series of lat-longs - you can readily plot them on a graph-sheet assuming the x axis as longitude and y axis as latitude (since India is entirely north of the equator and east of the 0 meridian you can readily use the first quadrant). You can even use Excel plots and replace the background with an appropriately aligned image of a map (orthographic projection). Paths can be plotted with line plots. A small grid region of about 500 sq. km. near the equator is easily dealt with for a lot of applications with Cartesian approximation. best wishes Shyamal https://sites.google.com/site/birdspot/ (an example geographic visualization without a GIS) -- For more details about this list http://datameet.org/discussions/ --- You received this message because you are subscribed to the Google Groups "datameet" group.
