Convert Decimal Degrees, DMS, Gradians (gon), Radians, NATO/Warsaw mils, and Quadrant Bearings, balance closed loops via the Bowditch Compass Rule, and verify Qibla bearings using both ellipsoidal geodesics and sun-shadow times.

GIS, Surveying & CAD Studios — frequently asked questions

Are survey CSV, KML/KMZ, or AutoCAD DXF files uploaded to a server?
No. Every coordinate transformation, KMZ archive extraction, geometry simplification, and AutoCAD R12 DXF generation runs locally in browser JavaScript with zero server uploads, logins, or credit limits.
How accurate are projected datum transformations and web-map measurements?
Ellipsoidal distances and bearings use Vincenty's WGS84 geodesic formulas (sub-millimeter computational accuracy) and authalic spherical surface areas. Datum transformations use published PROJ4 Helmert 3/7-parameter shifts (~1–5 m regional accuracy); for legal cadastral boundaries or millimeter-grade stakeout, always verify against official national NTv2 distortion grids and local GNSS control monuments.
Which CAD applications open the generated DXF files?
All exported drawings conform to the ASCII AutoCAD Release 12 (AC1009) specification with explicit $EXTMIN/$EXTMAX bounding extents, $INSUNITS, $PDMODE/$PDSIZE point display headers, and typed layers, opening cleanly in AutoCAD, Civil 3D, BricsCAD, DraftSight, LibreCAD, and QGIS.
Can I unpack compressed Google Earth .kmz archives directly?
Yes. Both the Interactive Map Studio and the GIS File Converter Studio decompress .kmz ZIP archives directly in memory using JSZip and parse the embedded doc.kml without external archive utilities.
