I've been asked to do a project that maps the bathymetry of a quarry lake. It seems like I've seen a feature in QGIS that would help with this if I took a bunch of depth points in the lake. Any thoughts on where to find this? And how to do it? And there's not a chance this data could already exist somewhere from remote sensing, soil surveys, etc.? Thanks |

There is almost global bathymetry coverage, but I doubt it is precise enough for your quarry. Check this similar question for both the source and a pointer to GRASS (which can be used from QGIS) and a conversion option: How to use SRTM30 Plus data with QGIS? If you measure enough points, you could create contours normally. Check out this tutorial. |
