Great place to ask IMHO. These is a combination of a suggestion and a fish for an answer that tells me no work is needed. I don't know how widespread the audience is relative to your standards.
1) Consider someone with a local coordinate system establish with a total station or similar classical methods. No assumptions on orientation of axes, except up is up. Let's assume there are perhaps hundreds of points. Perhaps this is just a data collector dump and perhaps it is gama output. Further assume the person has absolute positions (lat/lon/HAE) probably via GPS RTK, and perhaps standard deviations. I want to be able to enter the correspondence, and compute a transformation that can be not only used in qgis but stored in a file to be used with proj/gdal. And, I want to store the corresponding points so that I can re-open, change some, and add some, without starting over. There is a geoscience plugin that mostly does this but it seemed awkward for reasons I don't remember this minute. 2) Similar, but assume someone has a survey plan with angles and distances, and somehow (in a new plugin or separate) converts them to a local system (because one can ~never assume the angles are true to any particular geodetic coordinate system). Given 1, this is about entering the angles/distances and turning it into a layer, I think. There is a cadastral plugin but it seems to be about taking a shape and producing documents, vs taking documents and producing a shape. 3) With RTK, one can take 30s, 60s, whatever position traces on a mark. Then one can average those. Multiple such observations over multiple days can then be combined to form an estimate for the mark. There are interesting questions here about finding the mark by being close, vs labeling, and not labeling is a faster workflow. I'm doing this manually but it would be cool to be more automated. _______________________________________________ QGIS-User mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
