I have a Cerulean ROV Locator MkII on my Blue ROV2 and a gps puck topside. I use sonarview to see my topside location and the location of the ROV below but I usually work in open water where the default tiles tell me nothing. I work for a marine habitat mapping group and we have many rasters (bathymetry, backscatter, substrate models, etc.) that would make a great base map to use in SonarView so I can see my position relative to the features I am targeting for video transect surveys. Is there any way to load my own geotiffs into wither SonarView or Cockpit?

Hi @koehler, welcome to the forum 🙂

[GeoTIFF support for Cockpit is under active review](https://github.com/bluerobotics/cockpit/pull/2783) - you’re welcome to help test if you’d like to (either directly, or by providing some example files for us to confirm load properly+smoothly)!

I’m not particularly experienced with SonarView, but from [searching the docs](https://docs.ceruleansonar.com/c/sonarview?q=GeoTIFF) there seems to be support for _exporting_ GeoTIFF files, but not for importing them as part of the base map.

Hello Eliot,

Thanks for your quick response! Since your reply I saw that this functionality was merged to the latest main branch of Cockpit so I downloaded it and the Geotiff import and display worked perfectly. This will be a huge help to us as we attempt to survey a variety of seafloor features. I’ll post again once I have my layers loaded into Cockpit with nicer symbology to deomnstrate this new utility.
