Hi, I have through my work received a document with the positions and references of all of Petrobras fixed installations, FPSO's, mono-buoys, and movable rigs. The source itself is with all certainty not open, though I have not contacted Petrobras E & P to ask for the data to be freed for OSM. I doubt that this data will be freed that easily.
The location of the movable rigs are not of much interest to a map, these change a little too often to be any point in putting on a map other than special interest maps, and Petrobras and all other oil companies produce their own maps for such purposes. On the other hand, I can over time derive the limit of oil fields from these maps, and also I can pinpoint all the fixed installations. This is information more of interest to the map. But how can I get the information in this source cleaned? Can I for example extract the WGS84 positions from AIS, radar plotting, optical bearings? What can be included from the sources when I have external data to rely on? The positions in the source are UTM and Aratu projection (I know it should be simple converting, but will not start until I know I can have the source cleaned) A _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
