Development of a Georeferenced Topographic Map

We are seeking an experienced GIS, surveying, LiDAR, and point cloud processing professional to transform a cleaned point cloud dataset and GPS/RTK survey information into a fully georeferenced topographic model suitable for engineering design, construction planning, earthworks analysis, and quantity estimation. The selected specialist will receive cleaned point cloud files (LAS, LAZ, E57, RCP, RCS, or similar formats), GPS/RTK control data, and coordinate system information. All outputs must be accurately referenced to the provided WGS 84 coordinate framework while preserving spatial integrity and survey-grade accuracy. Scope of Services The successful candidate will be responsible for: Georeferencing the point cloud using supplied GPS/RTK control points. Validating registration quality and coordinate accuracy. Verifying alignment consistency throughout the dataset. Extracting the bare-earth surface and generating a Digital Terrain Model (DTM/TIN). Producing contour lines and terrain breaklines. Extracting spot elevation points with complete X, Y, and Z coordinates. Classifying and digitizing visible site features. Preparing professional GIS and CAD deliverables ready for engineering applications. Feature Extraction Requirements Where visible within the dataset, the following features should be identified, classified, and represented: Buildings and associated structures Boundary and retaining walls Fencing Roads, driveways, and access routes Pavements, sidewalks, and curbs Trees and vegetation Utility poles and related infrastructure Manholes and inspection chambers Drainage systems and channels Terrain breaklines Stairs, ramps, and access structures Embankments and grade transitions Any additional site features identifiable within the survey area 2D and 3D Data Requirements All extracted elements must be delivered in both: 2D planimetric format 3D format incorporating elevation attributes where applicable The final GIS dataset must contain accurate three-dimensional geometry with associated coordinate information. Required Deliverables The completed project should include: A consolidated DWG file fully compatible with AutoCAD Civil 3D GIS deliverables in SHP and/or GeoPackage format A 3D point dataset containing X, Y, and Z coordinates Digital Terrain Model (DTM/TIN) Contour mapping Spot elevation points Layer-organized CAD drawings with clear feature categorization Both 2D and 3D representations of all mapped features Quality Standards Deliverables will be assessed based on: Accuracy relative to supplied GPS control data Correct implementation of the WGS 84 coordinate system Consistency and quality of generated contours Elimination of spikes, gaps, and terrain irregularities Accurate feature extraction and classification Logical layer organization and full Civil 3D compatibility Preferred Software Experience Applicants should specify their proficiency with one or more of the following platforms: Leica Cyclone CloudCompare Trimble Business Center Autodesk ReCap Autodesk Civil 3D ArcGIS QGIS Equivalent professional surveying, GIS, and point cloud processing software will also be considered. Application Requirements Interested candidates should include: Examples of comparable projects completed previously A brief description of the proposed workflow and software tools Estimated project duration Fixed-price quotation Project Goal The objective is to obtain a survey-grade GIS and CAD dataset comparable to a detailed topographic survey, providing reliable information for engineering design, earthworks computation, construction planning, and quantity take-off applications.
