GeoKantar

GeoKantar is a surveying app for field work: coordinate transformations, calculations, survey and stakeout, parcel subdivision, PDF plan georeferencing and infrastructure mapping. Everything is in one place and works offline.

TOOLS

Coordinate Transformation
Single-point and batch transformation between more than 50 coordinate systems: Gauss-Krüger (zones 5, 6 and 7), MGI 1901 Balkans, the national grids of Serbia, Croatia, Bosnia and Herzegovina, Slovenia and North Macedonia, WGS84, UTM and US State Plane, with search by EPSG code. Recently used systems stay at the top of the list.

Area & Perimeter
Enter points manually, walk the boundary with GPS or draw on the map. Area, perimeter and side lengths update instantly, with export to KML, CSV and DXF.

COGO Calculator
Inverse, polar (radiation), line–line and distance–distance intersection, and area from coordinates.

Survey & Stakeout
GPS point capture with averaging, manual entry of known coordinates, and stakeout with compass and navigation to the point. Export to CSV and DXF.

Localization
Helmert calibration to control points, RMS and residuals to check accuracy, and grid/ground scale factor.

Parcel Subdivision
Import a parcel from DXF, CSV, GeoJSON, KML or SHP and split it by number of parts, area, frontage or road access, or draw the split line yourself. Export the parts to DXF and CSV.

PDF Underlay
Load a cadastral plan, site plan or design drawing from PDF and georeference it with control points or a known scale. Draw points, lines and polygons with snapping to drawing corners, or detect them automatically from a vector PDF. Export to DXF, CSV, KML, GeoJSON and an image with a world file for AutoCAD, Civil 3D and QGIS.

Leveling
Enter the starting height and stations; height differences and point elevations are calculated automatically, with export to CSV.

DXF to KML/KMZ
Convert DXF drawings for viewing in Google Earth, with parcel areas in m², dunams and hectares.

Infrastructure
Map infrastructure on a satellite map: sewers, water supply, electrical installations and street lighting. Points, lines, photos and a professional DXF export with 13+ layers.
