About

Project Overview I am developing an outdoor/off-grid mobile mapping app for New Zealand and need a GIS specialist to prepare a complete set of NZ recreation, conservation, access, and terrain layers. This project involves sourcing official datasets (DOC, LINZ, Herenga ā Nuku, GWRC, etc.), cleaning and simplifying the geometry, reprojecting to EPSG:3857, and exporting the final datasets as GeoJSON and MBTiles suitable for mobile offline use (MapLibre/Flutter). What You Will Deliver A structured folder containing the following processed datasets: DOC Layers DOC huts (points) DOC campsites (points) DOC walking tracks DOC roads DOC permitted boundaries DOC restricted boundaries Conservation Layers Public Conservation Land (PCL) boundaries Wilderness areas NZ Memorials Register Access / Recreation Fishing access Hunting access Public Road Parcels (LINZ) Trails Te Araroa Trail (full NZ route) Mountain biking tracks (DOC + regional) Walking access tracks (Herenga ā Nuku) Regional GWRC hunting blocks Risk ATES (Avalanche Terrain Exposure Scale) zones Technical Requirements Reproject all layers to EPSG:3857 (Web Mercator) Clean attributes (keep only essential fields) Simplify geometry for mobile performance Export format: Points/lines → GeoJSON Large polygons → MBTiles (vector tiles preferred) Ensure layers align with LINZ Topo50 base map Provide metadata including: Source URLs Licensing (LINZ and DOC CC-BY 4.0) Processing notes Folder Structure Required You will deliver files in this exact structure: MapLayers/ DOC/ Conservation/ Access/ Trails/ Regional/ Metadata/ layer_manifest.json Metadata should include: LICENSES.md SOURCES.md ATTRIBUTION.txt LAYER_INDEX.json Verification Requirements No geometry errors (NULL shapes, self-intersections) All files open cleanly in QGIS MBTiles render properly in a tile viewer All layers correctly clipped to NZ Simplified geometry suitable for mobile offline use Screenshots of layer alignment (e.g., huts/tracks on Topo50 basemap) Your Application Should Include Your experience with QGIS, LINZ, or DOC datasets Examples of similar GIS/MBTiles work Confirmation you can deliver all layers + metadata Your fixed price and estimated timeline Your availability to start immediately Timeline 5–10 days.
