Dear list,<br>
<br>
Please see in attached image what I am aiming to achieve with GDAL.<br>
The tool creating it is here, but I don't have arcgis:<br>
<a href="http://resources.arcgis.com/fr/gallery/file/geoprocessing/details?entryID=1FECB539-1422-2418-7FE1-77F9D088402D" target="_blank">http://resources.arcgis.com/fr/gallery/file/geoprocessing/details?entryID=1FECB539-1422-2418-7FE1-77F9D088402D</a><br>
<br>
The input is a set of points and a fixed grid (10x10km).<br>
The output a subset of the grid based on the points with the cells<br>
interlinked by some logic.<br>
<br>
My idea (probably not optimal):<br>
- convert the points to gridcell centroids<br>
- draw a line between the point and its neighbours<br>
- if the distance is inferior to a certain value -> intersect the line with<br>
the grid and keep the intersected cells<br>
- result: assemble resulting cells and export<br>
<br>
Not being a spatial expert, I'm not sure though this is the good way. Could<br>
you have a look and perhaps give me a few hints?<br>
<br>
Thanks a lot!<br>
<br>
Kevin<br>
