Jose Catala Posted June 29, 2023 Share Posted June 29, 2023 How to use maps in spotfire which are not EPSG:3857 (cylindrical projection)? Link to comment Share on other sites More sharing options...
Jose Catala Posted June 29, 2023 Author Share Posted June 29, 2023 Hi,I have loaded a TMS (Tile Map Service) of the north pole region (from Artic Web Map Tiles) into Spotfire. It is a map in Coordinate Reference System EPSG:3573.The map is properly displayed in Spotfire, but only if Map Chart Properties / Appearance / Coordiante reference System is set to EPSG:3857 (WGS84 Pseudo Mercator). If I set the CRS to be EPSG:3573 (North Pole LAEA Canada), then the Map is not displayed and the message " 'TMS Layer' can only be shown in the coordinate reference system 'EPSG:3857' " is displayed.I tried to leave the Map (TMS) in EPSG:3857, which is the only option allowing it to be displayed and then to set EPSG:3573 for the marker layer (from a table with latitude and longitude values), but the marker layer is not properly displayed.Any clues on how to proceed in order to plot a marker layer into a Map which is not in EPSG:3857 coordinates (cylindrical projection)? How should we proceed in order to enter a map in another type of reference system (e.g. via TMS) and then to display the marker layer properly??

Fredrik Rosell Posted June 30, 2023 Share Posted June 30, 2023 Hello Jose,There is an existing idea for this in the TIBCO Ideas Portal:Enhancement for TMS layer in Spotfirehttps://ideas.tibco.com/ideas/TS-I-5512A suggestion there was to use WMS layer instead.I have alerted people with a great amount of knowledge about maps about your inquiry. Hopefully one of them will have some good suggestions for you. Link to comment Share on other sites More sharing options...
Arnaud Varin Posted July 3, 2023 Share Posted July 3, 2023 Hello Jose,I confirm. TMS Layers in Spotfire map charts only support EPSG:3857 coordinate system. This is a limitation in Spotfire, and as Fredrik mentioned, there is an existing enhancement idea in the Ideas portal that I encourage you to vote for.You are able to display the TMS Layer (EPSG:3573) but the coordinate system is not correct (EPSG:3857). Therefore the problem is not on the marker layer (which should translate well either to EPSG:3857 or EPSG:3573), but on the TMS Layer side which only renders in EPSG:3857.Unfortunately I don't have a great suggestion for you at the moment. Best suggestion is to use a WMS Layer (we support different coordinate systems for WMS). I'm hoping the service you're using is available as WMS or you can find alternative services as WMS providing similar map. Link to comment Share on other sites More sharing options...
Jose Catala Posted July 10, 2023 Author Share Posted July 10, 2023 Thank you very much for your answers. It worked perfectly with WMS!TMS improvement idea voted!Regards,Jose Link to comment Share on other sites More sharing options...
