A lightweight viewer for geophysical grids. GeoTIFF, ER Mapper (open the .ers with its data file) and Geosoft .grd grids (with their .grd.xml for the coordinate system) are decoded in your browser and never uploaded. Every display control works on the original numeric values; nothing is written back to the data.
Read the user guide Opens in a new tab, so your grids stay open here.
Lightbox saves your work as you go and keeps your last few sessions in this browser, grids included, so you can pick up where you left off.

It goes to My Layers in your NextMaps account, where you can rename or delete it. The map draws plain coloured lines, so fault and fold symbols stay here. Only the lines and polygons are sent, never your grids.
Sending your interpretation to the map, to see it over the tenements, is part of NextMaps Premium.
