G-PhysicsPlanner map-based survey planning

Draw a survey area or line once, plan any geophysical method on it, and export a field-ready KMZ / GPX / CSV / DXF.

Magnetic · Gravity · GPR · Seismic refraction / MASW · ERT — all in one shared map workspace.

Shared survey area / line

WGS84 decimal degrees. For UTM coordinates, use the CRS-aware paste input below.

Line length: start drawing or enter endpoints.

Import KML / GeoJSON
Draw or paste a survey area / line to begin.

Magnetic grid parameters

Magnetic — quick estimate

Gravity grid parameters

Gravity — quick estimate

GPR grid parameters

GPR grids are continuous (no discrete stations). Swath count = number of clipped lines.

GPR hyperbola velocity analyzer

Upload a radargram, then click the apex and two points on the hyperbola arms.

Seismic / MASW spread

Draw one or more straight lines on the map (Line tool), then configure the spread.
 

Inline shots are equally spaced inside the active spread. End shots lie at the first and last geophones. Off-end shots extend along the first/last line segment; verify access in the field. For MASW, set inline and end shots to zero if only forward/reverse off-end records are required.

Refraction / MASW geometry

MASW depth estimate

ERT electrode layout

Draw one or more straight lines on the map (Line tool). Long lines auto-split into roll-along segments (25% overlap).
