I need a polished, professional PowerPoint deck created as quickly as possible. The slides will showcase and clearly explain the following focus areas: QGIS workflows, remote-sensing techniques, GIS mapping principles, technical report writing standards, accurate data-entry practices, and a brief look at basic Python scripts that tie these pieces together. The narrative should be concise yet visually engaging—think clean layouts, relevant icons or screenshots (especially from QGIS), and infographics that make spatial data concepts easy to grasp for a professional audience. I’ll supply any raw figures, maps, or text snippets you request; you handle structure, design, and the final storytelling flow. Please respond only if you can deliver fast and have solid, demonstrable exper...

I am close to submitting a research article to the Journal of Degraded and Mining Lands Management (Q3, Scopus) and need a seasoned editor who has already worked with geography or remote-sensing journals. The study tracks sebkha dynamics amid rapid urban expansion on the Al-Khafji coastal plain, using NDWI and MNDWI as core indices. What I need from you • Strengthen the overall scientific writing—clarity, logical flow and a polished academic tone. • Give extra attention to the Discussion and Conclusion, sharpening the argument and tightening data interpretation so the take-home messages are unambiguous. • Smooth out any lingering AI-generated phrasing; the narrative must read naturally and professionally. • Format the entire manuscript (text, citations,...

We are looking for an experienced GIS and remote sensing specialist to generate a high-quality topographic map from LiDAR data. The freelancer should be able to process the point cloud data, create digital elevation models (DEM/DTM), and generate accurate contour lines. Please provide examples of your previous topographic mapping projects.

I’ll provide raw LiDAR point-clouds and need you to turn them into presentation-ready topographic products—fast and flawless. Your workflow will start in Global Mapper (your stated preference) to import and classify the clouds, then continue through DEM generation, contour extraction, hillshade creation, and optional 3-D scene building. I review spot elevations against ground-control before sign-off, so accuracy down to the decimetre is essential. Deliver the first draft as soon as practicable; once I return comments, I expect a quick final turnaround. Deliverables • Clean DEM in GeoTIFF format • Contour lines (vector) • Hillshade raster • Lightweight 3-D model or scene file (any common format you support) • Print-quality PDF map and a fully...

I need a complete flood-risk zoning model for a single city, concentrating only on river flooding. I can supply you with several decades of historical flood records together with the hydrological series (stage, discharge and rainfall) that fed those events. What I do not yet have—and may need you to source or recommend—is the most suitable terrain surface for hydraulic computations. Here is what I am looking for: • Build and calibrate a hydraulic / hydrologic model (HEC-RAS, InfoWorks ICM, TUFLOW, or any tool you prefer) using the historical and hydrological datasets I will share. • Simulate at least the 10-, 50- and 100-year return periods, generating depth, velocity and extent rasters. • Translate those outputs into GIS-ready flood-risk zones (low / medium / ...
