AICADGIS - Web-Based CAD & GIS Editor

EPSG Coordinate Converter & Reprojection Tool

Seamlessly transform your spatial data between local CAD coordinates and real-world geographic reference systems. Easily reproject DXF, SHP, and GML files to standard EPSG codes like WGS84 (EPSG:4326) directly in your browser.

How to Reproject CAD Data to GIS (WGS84)

A common challenge in geomatic engineering is integrating legacy CAD site plans (which often use arbitrary, unreferenced local coordinates) into modern GIS platforms like QGIS or ArcGIS. Our web-based transformation engine allows you to assign a specific EPSG code to your incoming DXF or DWG files and accurately reproject the geometry to real-world coordinates.

Supported Coordinate Transformations

  • To WGS84 (EPSG:4326): Convert your local Cartesian vectors into the global standard for GPS data and web mapping.
  • Web Mercator (EPSG:3857): Instantly prepare your AutoCAD DXF files for overlay on Google Maps, OpenStreetMap, or Leaflet applications.
  • National Grids: Support for specific national UTM zones and localized grid systems critical for spatial address registration and land surveying.

Why Coordinate Systems Matter

Without a defined Spatial Reference System (SRS), a spatial polygon is just a shape floating in digital space. By assigning the correct EPSG code before exporting your data as a Shapefile or GML, you ensure that your boundaries, utility lines, and topographical points drop precisely where they belong on the globe.
