Irfan GIS Portfolio

A comprehensive showcase of large-scale Geospatial and Civil Engineering projects. This portfolio highlights my expertise in maintaining 99.89% data accuracy across massive datasets, including the management of 200,000+ land parcels for the AP Resurvey project.

Key Technical Competencies:

GIS/CAD: ArcGIS Pro, QGIS, AutoCAD, Civil 3D.

Engineering: M.Tech in Structural Engineering with a focus on infrastructure assets.

Operations: End-to-end project management, from drone data processing to final database delivery.

Bridging the gap between high-precision mapping and structural integrity.

8. Strategic Roadmap: HMDA 3D Digital Twin DIRECT APPLICATION OF SME EXPERTISE TO THETCURREGION LiDAR &Ground Truth I will utilize 8 years of CORS-RTK expe- rience to ensure that the LiDAR point clouds match the physical ground real- ity exactly. By establishing high-precision Ground Control Points (GCPs), we will eliminate the vertical and horizontal drift that typically affects large-scale urban mod- els. High-Fidelity Modeling Applying Structural Engineering logic to Level of Detail (LoD) building extraction. I will oversee the mathematical snap- ping of building vertices to the 6th decimal place, ensuring that the 3D semantic layers are consistent, non- overlapping, and survey-accurate for the master database. Scrum Framework I will manage the TCUR map- ping program using tile-based production Sprints. This Agile approach will facili- tate a 20% increase in through- put while maintaining rigorous QA/QC gates for every tile be- fore final integration. www.IrfanMaps.com SHAIK MOHAMMAD IRFAN | GIS SME | HMDA 3D DIGITAL TWIN 08 / 08 MORE AT:
