>>> Lionel Roubeyrie <[EMAIL PROTECTED]> 07/23/08 9:37 AM >>> I want to "convert" a filled contours map generated with Basemap (example here : http://imagebin.ca/view/3nYnN3.html) to a polygon shapefile (vector).
After multiple tests, I can retrieve the polygons points coordinates via matplotlib.Patch and save them in a shp file. Now I have troubles with "real" coordinates and meta-datas, but nothing impossible :-) >>> Hi, If you're after a 'quick and dirty' solution. As I understand it a KML file can be used to specify the Latitude and Longitude extent of a raster image (See 'Ground Overlays' at http://code.google.com/apis/kml/documentation/kml_tut.html). If you can accept some distortion of the text on your image (should be small with a small region) and can work out the size of each pixel in degrees of lat and lon, then all you need to do is write a simple text file to specify where Google Earth should display your Basemap contour map. What you're doing does sound more elegant, but more complex.
