"Terrain analysis is my day job. I'm a U.S. Army geospatial analyst — I build slope, viewshed, and terrain suitability products daily, to standards where accuracy actually matters. I help clients answer ground questions: Where can this be built? What can be seen from here? Which route, parcel, or site makes sense? You get a clean, professional map or analysis package — clear layout, documented data sources, delivered in the format you need (PDF, GeoTIFF, shapefile, or GeoPackage). I also build boundary and census datasets for US location-data companies — sourcing official government boundaries, joining them to census figures on the correct geocodes, and running a full QC pass (geometry validity, zero orphan joins, national totals cross-checked against independent sources) before anything ships. Every delivery includes complete documentation and a peer-reviewable methods note. Five-star delivery record so far. What I work with: QGIS end-to-end (terrain analysis, spatial analysis, cartographic layout), GRASS and GDAL processing (slope, aspect, hillshade, viewshed, watershed), USGS 3DEP elevation data, and LiDAR-derived DEMs. Every analysis ships with a methods note stating exactly what the data does and doesn't support. US-based, deadline-driven, and precise — if something in your requirements is ambiguous, I'll ask before I build, not after."
