Meet the Team Behind GIS Mappers

A multidisciplinary team with 25+ years of experience across land survey, hydrography, bathymetry, GIS, drone mapping, LiDAR, CAD automation, software development and GeoSystems integration.

One integrated team

Field-proven surveyors, engineers and developers under one roof

The strength of GIS Mappers Group is its people. Our team combines decades of practical, on-site field survey experience with modern digital technologies — including GIS, CAD, AI, hydrographic systems, drone mapping, LiDAR, point clouds and software automation — so data captured in the field flows cleanly into the deliverables our clients depend on.

Surveyors, hydrographers, GIS analysts, CAD and software engineers and field crews work as a single connected unit across our three divisions: GIS Mappers (survey services), GIS Mappers Software (processing & automation) and GeoSystems (survey technology). The result is accountable, standards-led delivery from the first ground-control point to the final digital model.
