Your saved depth datasets — uploaded, imported, or hand-traced. Reuse them on any map (they auto-apply by location), or share to the community pool so every mapx user can use them. Upload any depth format — GeoJSON, zipped shapefile, KML/KMZ, GeoPackage, DXF, GeoTIFF/DEM rasters, or sonar logs (.sl2/.sl3/.gpx/.csv). Any projection is handled.
