Comprehensive Makkah GIS Terrain Analysis

About the project

I need a full terrain-focused GIS study of the Makkah Region so I can fabricate an accurate 3D physical model later on. Please base the work primarily on Copernicus DEM, and feel free to blend in SRTM, ALOS World 3D, any available LiDAR tiles, plus Sentinel-2 or Landsat imagery where they help refine detail or colour a final render. QGIS or ArcGIS Pro are fine; Global Mapper, GDAL and Google Earth Pro can support intermediate steps. I’ll provide the exact AOI boundary once we start. From there, I expect the following discrete outputs, all properly georeferenced in the same projected coordinate system: • Area & perimeter calculations • Min, max, mean elevation and range • Contour set at custom intervals • Slope, aspect and hillshade rasters • Terrain Ruggedness Index (TRI) & Topographic Position Index (TPI) • Ridge, valley and peak layers • Watershed and drainage network, plus basic morphometrics • 3-D surface area measurement • Road gradients and elevation profiles if any roads fall inside the AOI • High-resolution 3-D visualisation (static image and exportable scene) • Complete GIS project package (layers, styles, metadata) • A concise, polished PDF report that walks through methods, maps and key statistics Acceptance criteria 1. Every raster at ≤30 m resolution, resampled consistently. 2. Vector outputs topologically clean and snapped. 3. Project file opens with no missing links; symbology preserved. 4. PDF clearly cites data sources and CRS. Let me know your preferred workflow and estimated turnaround, and I’ll supply the boundary shapefile so you can begin right away.
