...layers and I need a clear, data-driven picture of how land use patterns emerge across the study area. The core objective is to identify spatial relationships rather than predict future change, so the work will centre on exploratory spatial analysis and compelling map visualisation. Here is what I expect: • Clean, well-documented GIS processing of the raw geographic data I provide (Shapefile or GeoJSON). • Pattern-detection techniques applied—hot-spot analysis, kernel density, or other methods you find appropriate—so the resulting outputs highlight significant clusters and gaps in land use. • A polished map series (static PNG/PDF and an optional interactive web map if feasible) that communicates the findings to a non-technical audience at a glance....

...I need the municipal zoning boundaries digitized for several cities. For each city, I will provide the official zoning plan PDF (published by the municipality). Your job is to georeference each PDF and trace all the zoning polygons, then export the result as a GeoJSON file (CRS: EPSG:4326 / WGS84). You do not need me to provide coordinates — all cities are real, well-known municipalities in Québec and can be geolocated independently using OpenStreetMap, Google Maps, or Quebec government cadastral data. Deliverable per city: A GeoJSON file with one polygon per zone, where each polygon has two attributes: zone — the exact zone code from the map (e.g. H-308, C-125, I-405) nom — the zone category (e.g. Résidentielle, Commerciale, Industrielle, ...

...the relevant Districts appear, then Talukas, Villages and finally the exact Survey Number. When the final number is chosen, the system should render a map view and auto-generate a printable, shareable report mimicking the layout and level of detail shown on landreport.in. Besides simply viewing the data, users must be able to work with common GIS files. The app should let them: • import KML, GeoJSON, Shapefile (SHP) and GPX • export the selected survey polygon back out to the same formats On the map itself they should have measurement and editing utilities: draw a line, polygon or path, move or reshape it on the fly, and read real-time lengths and areas. I’m happy with any robust mapping stack—Leaflet, Mapbox GL, OpenLayers or an equivalent—as lo...

I have two georeferenced GeoJSON layers and need them joined by location in ArcGIS using arcpy. The join must follow the Intersect rule—any overlap between features should merge their attributes. The end product I’m after is a single, clean georeferenced dataset that I can drop straight back into my mapping workflow. Here’s what I need from you: • An arcpy script (suitable for ArcGIS Pro or ArcMap 10.x) that reads the two GeoJSON inputs, performs the intersect-based Spatial Join, and writes out the new dataset. • Clear, inline comments so I can tweak field mappings later on. • A brief run-through in the script header or a separate README explaining required libraries, how to execute the code, and where the output will appear. If the la...
I need a clean, lightweight way to display country borders in my existing CesiumJS scene. The goal is a simple visualization: solid-line outlines that sit accurately on the globe with no tooltips or click actions—just clear, precise borders that render efficiently. You can work from a reliable GeoJSON or TopoJSON dataset, or fetch borders through an open-source tileset if that keeps the bundle smaller. Whichever source you choose, please handle the projection and height reference so the outlines hug the terrain correctly without z-fighting. Deliverables • A short, commented JavaScript module (ES6) that plugs into a standard Cesium viewer instance and loads the borders. • Styling set to solid lines, with an easily adjustable color and width parameter. • A...

The detector has to work at desert scale, so please build it with an established computer-vision framework (e.g., TensorFlow, PyTorch, YOLO, or a similarly robust model) and output the findings in both human-readable (an image with bounding boxes or a simple web map) and machine-readable form (CSV/GeoJSON with lat/long, time stamp, confidence score). Once I apply the tool to a new location and receive a list of car and truck pictures and coordinates automatically reflected on the map, no manual clicks—I’ll consider the project complete....

...receive tax parcel numbers for each county. What I care about most is rock-solid boundary delineation—nothing approximate or generalized. Each parcel line must register cleanly when overlaid on the raw imagery, standing up to a surveyor’s eye. Wherever imagery gaps appear, I expect you to flag them rather than fill them with guesswork. Deliverables (all required): • A GIS-ready layer (Shapefile or GeoJSON) containing every parcel polygon, snapped and topologically clean • An accompanying metadata file that documents methods, imagery dates, and any control points used • A brief QA/QC report listing checks run, error rates, and any parcels that need follow-up ground verification Acceptance criteria: • Parcel boundaries align to visible physica...

I have a sizable environmental dataset that needs spatial analysis and clear, actionable insights. The files are already organized, but I’m flexible on format—if you prefer Shapefiles, GeoJSON, or even CSV, I can supply the data in whichever structure lets you work most efficiently. Here’s what I’m after: • A thorough spatial analysis that highlights key environmental patterns, anomalies, or correlations. • Visual outputs—maps, charts, or dashboards—that make the findings easy to present to non-technical stakeholders. • A short written summary explaining your methodology, the tools you used (ArcGIS, QGIS, Python/GeoPandas, etc.), and any recommendations that arise from the results. If additional preprocessing or data cleaning ...
