Applications

Two applications, one project

Carte and MawCAD share your projects: what you survey on the map lands in the CAD in Lambert coordinates, layer by layer.

Carte

Survey and measure

Points, lines and parcels on satellite imagery, live X/Y in 32 coordinate systems, elevations, contour lines, long profiles and utility networks.

  • Morocco Lambert North, South, Sahara North and Sahara South
  • SRTM elevations, contour lines and point grids
  • Typed lines: roads, sewers, water, power, telecom
  • Your live position on the map

MawCAD

Draft and deliver

Free account

A complete surveying CAD: layers, snapping, dimensions, TIN and contours, profiles, earthworks, parcels and networks.

  • Your Carte drawing arrives in Lambert, ready to edit
  • TIN, contours, profiles and earthworks
  • Road alignments, networks, parcels, coordinate schedules
  • DXF, GeoJSON, Shapefile, LandXML and SVG export

The workflow

Three steps, nothing typed twice

  1. 1

    Survey in Carte

    Pick your Lambert zone, draw points, lines and parcels, type your networks, generate the contour lines.

  2. 2

    Open in MawCAD

    One click: points, lines, contours and networks arrive in projected coordinates, each on its own layer.

  3. 3

    Draft and export

    Complete the plan, compute areas and volumes, then export a DXF for the office.

Coverage

Built for the Maghreb and France

The four Morocco Lambert zones (Merchich), North and South Algeria, North and South Tunisia, Lambert-93 and the CC 9 zones, UTM 28 to 32 N: 32 systems, computed in your browser and checked against the EPSG registry.

Your position, live

One button shows you on the map while you survey. The position stays in your browser.

In the field

Free-licensed photographs — see the credits
Field work remains a matter of method: instrument set-up, repeated observations, a field book kept as you go.

Receiving and checking a point with a GNSS receiver: accuracy depends on the sky, the base and the quality of the observations.

The total station remains the reference instrument for precise stake-out: distance, angle, and control by back sight.

A photogrammetric flight is planned like a survey station: flight plan, image overlap and ground control points.
