Budget: €250 – €750 EUR

roject Title:

3D Feature Extraction (30ha Landfill Site) from LiDAR (.LAZ) and Orthophoto
Project Description:

"I am looking for a GIS/Topography expert to extract 3D vector features for a 30-hectare Landfill / Waste Management site.

Data provided:

1 Point Cloud file (.LAZ).

1 High-resolution Orthophoto (GeoTIFF).

Deliverables:

A 3D DXF or DWG file containing the following features:

Top of embankments/ridges (Crêtes de talus / Cordon).

Bottom of embankments/toe of slopes (Pieds de talus).

Ditch flowlines (Fil d'eau des fossés).

Vegetation boundaries (Limits of bushes, shrubs, and forest areas).

Specific Technical Requirements:

Landfill context: The site is a waste disposal center. Accuracy on slopes and drainage is essential.

Precision on small relief: There are small earth embankments (cordon) approximately 30cm high. You must ensure the 3D polylines are accurately snapped to the ground points.

Vegetation limits: Please provide boundaries for forested areas and thick bushes.

Volume of work: The total area to be processed is approximately 30 hectares.

The lines must be continuous 3D polylines (with Z elevation).

Software preferred: Global Mapper, Civil 3D, or Carlson.

I will release the payment only after checking the 3D accuracy of the breaklines in AutoCAD.
