<br>difference between Oracle Spatial and PostGIS is the geodetic<br>coordinate support.<br><br>The CNES is very interested in adding this support into PostGIS, by<br>funding a project for that.<br><br>What would be, according to you, the efforts needed to integrate such
<br>a support into postgis, and not only some functions working on<br>spheroids ?<br><br>Would it require to define geodetic index, would it be possible to<br>switch to polar coordinate system when dealing with geocentric SRS,
<br>like Oracle does ?<br><br>Any clue would help us to define the steps necessary to integrate this<br>support, and the the time/effor it will take.<br><br>Thanks<br><br>Nicolas<br>_______________________________________________
