Built for Field Professionals

The preferred converter of expert land surveyors

Go from the field to the final plan without any technical friction.

AutoCAD DXF & SCR Plans

Instant generation of 2D/3D DXF files and SCR/LISP scripts. 100% compatible with AutoCAD, Covadis, Mensura, and QGIS.

Map Locator & Auto-EPSG

Enter any X, Y coordinates: TopoTeam automatically identifies matching projection systems (Lambert 93, CC, UTM, Merchich, Voirol...) and pinpoints the location on satellite map.

10,000+ EPSG Reprojection

Convert point files (CSV, KML, DXF) across 10,000+ global geodetic projection systems using native Proj4 engine.

Bidirectional DXF & KML

Export to KML/KMZ for Google Earth and extract raw CSV point listings directly from any DXF drawing in one click.

Geoid Models & Orthometric Z

Convert ellipsoidal GNSS Z heights to orthometric elevations using official geoid grids (RAF20, RAC09, EGM96).

Interactive Viewer & Measurements

Inspect points in real time on 2D or satellite maps, adjust text scaling, and take distance measurements before exporting.

Custom Layers & Field Codes

Automatic layer creation per field code with full customization of colors, symbols (cross, circle, combo), and attributes.

100% Confidential Local Processing

100% local processing performed directly inside your browser. No topographic survey or confidential data is transmitted to external servers.

Multi-Format & Total Station Support

Full support for CSV, TXT, XYZ, PTS, KML, KMZ, and DXF files from total stations (Leica, Trimble, Topcon), RTK GPS, and LIDAR Drones.

"TopoTeam saves me at least 30 minutes per as-built file. No need to fight with complex AutoCAD scripts: I drag my file, configure my layers visually, and the DXF opens perfectly."

Frequently Asked Questions (FAQ)

Everything you need to know about converting your field surveys.

Which professions is TopoTeam designed for?
TopoTeam is designed for all field measurement and CAD drawing professionals: Licensed Surveyors, Topographic Technicians, Civil Engineers, Architects, Drone/LIDAR Pilots, and GIS Cartographers.
How does the coordinate conversion and KML/DXF support work?
You can drag and drop coordinate lists (CSV, TXT), Google Earth files (KML), or AutoCAD drawings (DXF). TopoTeam parses them in real time to generate AutoCAD drawings, extract coordinates to CSV, or reproject point lists locally.
Are my field data confidential?
100% Yes. Data processing is entirely done locally in your web browser. No field points are sent or stored on an external server.
Which CAD / drafting software are compatible?
The generated DXF files comply with Autodesk specifications and are compatible with AutoCAD, Covadis, Mensura, MicroStation, QGIS, ZwCAD, BricsCAD, and DraftSight.
Which projection systems (CRS / EPSG) are supported?
TopoTeam supports all global projection systems. In addition to pre-configured options (Lambert 93, CC42 to CC50, NTF Lambert II, UTM, WGS84, Lambert 72, MN95, NAD83, Merchich...), you can search and load absolutely any global EPSG code (over 10,000 systems supported) using our integrated search tool.
Is the tool free without registration?
Absolutely. TopoTeam is freely accessible online without any required account creation or prior installation.

How to batch reproject coordinate systems?

What is an EPSG code?

An EPSG code is a unique identifier used to specify a coordinate reference system (CRS). It helps GIS and surveying software precisely locate coordinate data on the Earth's surface.

How do I convert coordinates between different EPSG systems?

Simply upload your CSV file with your coordinates. Select your source EPSG system (e.g., WGS84 - EPSG:4326) and your target EPSG system (e.g., UTM Zone 31N - EPSG:32631). Our tool uses precise mathematical transformations (Proj4) to batch convert your entire file instantly.
