Hello OPM community!

I am a geography/GIS college student who is taking a class in web mapping. I stumbled across your [Mars basemap](https://www.openplanetary.org/opm-basemaps/opm-mars-basemap-v0-2) and thought it would be perfect to use for a fun term project.

However, I’ve been unable to locate the line data for the topography contours. The link provided doesn’t seem to be functional.

If someone knows where this data is located, I would be very appreciative!

Hi @nick-cramer11,

Welcome on the OpenPlanetary forum.

I believe the planetary datasets distributed by carto are located [here](https://openplanetary.carto.com/u/opmbuilder/datasets).

Do you mind checking if this solves your issue?  
Thanks!

Thank you! This dataset list is exactly what I was looking for. The link still is not working on the original page for the Mars basemap, but now I have the data.

Have a lovely day!
