A native desktop GIS built for geoscientists working with subsurface and surface data. Bring in your rasters, vectors, grids, and well data — then explore, analyze, and visualize them, entirely on your own machine. No cloud. No latency. No compromise.
Drop a grid on the map and it renders with a sensible color ramp, contours, and a legend — no fiddling required. Hillshade, transparency, and ramp choices are a click away.
Layers stack the way you think about them: wells over grids over basemaps, reordered by drag, toggled at will.
The Identify tool reads through every visible layer at the point you click — well attributes, grid values, feature properties — and lays them out in one place.
Found what you were looking for? Zoom to it and keep moving.
Click out a path or a polygon and read off distance, bearing, and area as you go. Snap to vertices when precision matters; switch units without re-measuring.
Real projects arrive in a mix of coordinate systems — NAD27 shapefiles from one vintage, WGS 84 exports from another. Meridian keeps a full EPSG library with search and favorites, tracks the CRS of every layer, and reprojects on the fly so everything lines up on the map.
A real desktop application for Windows, macOS, and Linux. Your data never leaves your machine, and the whole project lives in a single file you can copy, archive, or share.
Analysis operations always produce new layers — your source data is never modified. Every derived grid remembers where it came from and how it was made.
Reads the formats geoscientists actually have — from modern GeoTIFFs to legacy gridding packages — and grows with optional domain modules for petroleum, geothermal, and carbon capture.
Meridian GIS is a standalone product with optional domain modules. Start with the base. Add domains when you need them.
