Convert & Reproject Your Coordinates Online
Import CSV, TXT, XYZ, or PTS files. Instantly convert coordinates across 10,000+ local EPSG geodetic projection systems.
Drag and drop your CSV / TXT file to reproject
or click to browse your files (.csv, .txt, .xyz, .pts)
CSV Import Options
The character that separates your X, Y, Z coordinates.
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."

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.
