![]() To ensure that the points are regular and at. Lastly, I renamed it to “ETRS89/UTM 33N RW+3500000 Brandenburg” (it’s the first information right behind PROJCS[ ). The used software, Quantum GIS (QGIS), is a complex and powerful tool very helpful for the mentioned calculations that is widely used by professionals. The value 0.5 corresponds to the size of a raster pixel, which means that QGIS generates a point for each pixel. Secondly, I had to delete AUTHORITY to not confuse the algorithm … this was obviously not EPSG 25833 anymore. Notably “false_easting”,500000 became “false_easting”, 3500000 - representing the leading 3. Here, I copy- and pasted in the one from above and changed just few parameters. I navigated on the top navigation bar of QGIS to Settings opened Custom CRS ( Custom Projection) and created a new projection. So, I took the EPSG definition from here PROJCS],AUTHORITY],PRIMEM],UNIT],AUTHORITY],UNIT],PROJECTION,PARAMETER,PARAMETER,PARAMETER,PARAMETER,PARAMETER,AUTHORITY,AXIS,AXIS]Īnd used it to create a custom projection in QGIS. QGIS meaning is Quantum Geographic Information Systec and other full form of QGIS definition take part in below table. Therefore I had to create a custom projection. They’ve got this helpful page how to deal with the too high EAST value in a postgreSQL database, but I just wanted to take a quick look using QGIS and not import it into a database. Now, the dataset I received this time was polygon data. Actually, I might have been able to do that within QGIS with the table calculator? Not sure. The first data set I got was a point layer, so I simply created EAST and NORTH columns, exported the data, opened it in LibreOffice, calculated – 3000000 from the EAST column, re-imported everything in QGIS and it was fine. So if you use the “normal” EPSG 25388 (ETRS 89, UTM zone 33n) for Brandenburg you end up somewhere near the Caspian Sea with your data. For historic reasons, they have a system where the EAST coordinate has an added “3” in front. GIS applications enable users to create interactive queries (user-created searches), analyze spatial information, edit data in maps. (functioning as singular) physics statistics concerned with the distribution of a number of identical elementary particles, atoms, ions, or molecules among possible quantum states Collins English Dictionary. In my PhD I work with data from the Heritage Management Brandenburg, which is the Bundesland (state) “around” Berlin. Description: Quantum Geographic Information System (QGIS) is a cross-platform open source Geographic Information System (GIS) that integrates, stores, edits, analyzes, shares, and displays geographic information. Recently I had to tweak an EPSG definition in QGIS, because the data I received had a systematic error in the EAST coordinates.
