Hi,
I have a .txt file which contains latitude,longitude,radius values
seperated by a delimiter say ';'. I have to mark these points on map and
draw circle with corresponding radius given in .txt file. I kindly request
anyone to help me out how to carry on this task. The main issue in drawing
circles is that radius has to be read from .txt file. It will be great full
if I can get the code for the same.
You can connect to a text file using OGR. I don't remember the syntax,
but little bit of Google-ing, and you should be able to find the pages
that describe how to do this. OGR (I think it is some kind of virtual
driver) will help you draw points, and you can read the radius to draw
the circles. A little bit of programming will be required.
