I am trying to implement a terrain from Berlin with data (TIFF format) from the geoportal of the state of Berlin, but i get this error from the heron component: "1. Solution exception:Cannot find coordinate operations from ENGCRS["unnamed",EDATUM[""],CS[Cartesian,2],AXIS["easting",east,ORDER[1],LENGTHUNIT["unknown",1]],AXIS["northing",north,ORDER[2],LENGTHUNIT["unknown",1]]]' to EPSG:25833’.
Hi @Rafaelo_Xhangolli ,
Can you post a link to the source of the TIFF file so I can help troubleshoot? The “unknown” text in the coordinate system description is likely the issue.

Hey @Brian_Washburn,
thank you for your response. The link to the source is this: Geodatensuche
I thank you for your help and looking forward to hearing back from you.

Hi @Rafaelo_Xhangolli
It appears the terrain tile you are referencing (dgm1_33409_5652_1_sn.tif) is outside of your boundary. There are actually the corners of four terrain tiles intersecting within the boundary:
dgm1_33410_5653_1_sn.tif
dgm1_33411_5653_1_sn.tif
dgm1_33411_5652_1_sn.tif
dgm1_33410_5652_1_sn.tif
Try downloading those and merging them in QGIS, then use this merged tif with ImportTopo. I plan to add a raster merging component to Heron soon, but for now it’ll need to be done outside. Ideally, the data source would provide an ArcGIS REST service like the USGS 3DEP service or a WMS service so you could just query whatever boundary you want and wouldn’t need to stitch tiles together.

I am having issues with generating contour lines and a mesh. It gives me an error that “One or more boundaries are outside of the bounds…” I tried change the size of the rectangle, but nothing changes. Any advice?
I’m very new to this, so I’m not sure what that is, but I did figure it out. It started to work when I unchecked clip topography to boundary. Thank you!
