Georeferenced Topographic Plan Creation

Project Description I am looking for an experienced GIS, surveying, LiDAR, and point cloud processing specialist to convert a cleaned point cloud and GPS survey data into a fully georeferenced topographic dataset suitable for engineering, construction planning, and quantity take-off workflows. I will provide: Cleaned point cloud data (LAS, LAZ, E57, RCP, RCS or similar format); GPS/RTK survey observations and control points; Coordinate reference information. All deliverables must be referenced to the supplied WGS 84 coordinate system and maintain full geospatial accuracy throughout the project. Scope of Work The successful freelancer will be required to: Georeference and validate the point cloud using the supplied GPS control points; Verify registration accuracy and coordinate consistency; Extract the ground surface and generate a Digital Terrain Model (DTM/TIN); Generate contour lines and terrain breaklines; Extract spot elevations and topographic points with full X, Y and Z coordinates; Classify and vectorize all relevant visible features; Produce both GIS and CAD deliverables ready for professional use. Feature Extraction Requirements The following visible elements must be identified and represented wherever present in the point cloud: Buildings and structures; Boundary walls and retaining walls; Fences; Roads and access tracks; Pavements and curbs; Trees and vegetation; Utility poles; Manholes and inspection chambers; Drainage features; Terrain breaklines; Stairs and ramps; Level changes and embankments; Any other relevant site feature visible within the survey. 2D and 3D Deliverables All extracted features must be provided in: 2D planimetric representation; 3D representation with elevation (Z) values where applicable. I require a complete GIS dataset containing true three-dimensional geometry and coordinates. Required Deliverables A single DWG file fully compatible with AutoCAD Civil 3D. GIS files in SHP or GeoPackage format. 3D point dataset containing X, Y and Z coordinates. Digital Terrain Model (DTM/TIN). Contour lines. Spot elevation points. Layered CAD drawing with logical organization of all extracted features. All features represented in both 2D and 3D formats. Quality Requirements The final work will be reviewed based on: Accuracy against supplied GPS control points; Correct georeferencing and preservation of WGS 84 coordinates; Consistency and quality of contours; Absence of spikes, voids, and terrain anomalies; Proper feature classification; Clean layer structure and Civil 3D compatibility. Preferred Software Please indicate your experience with software such as: Leica Cyclone CloudCompare Trimble Business Center Autodesk ReCap Autodesk Civil 3D ArcGIS QGIS or equivalent professional surveying and GIS platforms. When Applying Please provide: Examples of similar projects; Software and workflow you intend to use; Estimated completion time; Fixed-price quotation. The objective is to obtain a professional survey-grade GIS and CAD deliverable equivalent to a detailed topographic survey, fully usable for engineering design, earthworks calculations, construction planning, and quantity take-offs.
