Step characteristics on raster maps (Mathieu Basille)
Dear Arnaud, This is actually on my todo list, a test with the polygon approach, although I'm not sure how to start to "polygonize" the segments... But in the end, that would allow a performance comparison with different approaches (and that would also allow the calculation of the characteristics of buffers around the segments, which might be interesting for us, too). Thanks for the suggestion, Mathieu. Le 03/10/2010 10:04, Arnaud Mosnier a ?crit :
Hi Mathieu, An easy workaround could be to convert each segment to a polygon doing a very small buffer around each segment then use the overlay method to obtain info in each of these polygon. Arnaud
