I have been given a small project for plotting easting/northing coordinates read from a text file as a polygon. As I am very new to mapping in VB .net, I am looking for some examples or references on internet or any documentation or tutorials to understand how the mapping application works. I went through GMAP and found it very useful, but don't know if I can use it as GIS engine to plot the polygon on it. I don't need any background map/city information/country or anything related to googlemap etc. I only need a blank GIS engine to use it for plotting my own coordinates in VB .net (NOT in C#). Any reference or help will be highly appreciated.. Thanks in advance !!!
