Executive Summary · Sovereign Geospatial AI · July 2026

Own the imagery. Own the models. Own the answers.

One desktop-sized NVIDIA DGX Spark delivers aerial-imagery AI, feature extraction, and an autonomous agent — running entirely on-premises, on open-weight models and public data. After setup, it works with the network cable unplugged: no cloud GPU bills, no metered API calls, no data leaving the building.

What it does

Serves 3-inch aerial imagery of the Denver region (DRAPP 2022) from local Cloud-Optimized GeoTIFF — sub-second map tiles, no external host.
Extracts features by plain-English prompt — “swimming pool,” “solar panel,” “roofline” — using open-weight SAM-family vision models accelerated by the NVIDIA GB10 Grace Blackwell Superchip.
Reasons and orchestrates locally with a Qwen language model driving the Hermes agent: ask questions, get maps, reports, and datasets back.
Improves with free labels — DRCOG's professionally digitized roofprints and pavement data train production-grade extractors at zero data cost.

What it retires

AWS EC2 GPU instance for imagery segmentation — recurring spend eliminated.
Hosted LLM API usage for agent reasoning — replaced by local open weights.
External imagery hosting and per-request map service dependencies.
Data-residency risk — client imagery and derived features never transit a third-party cloud.

Why now

DRAPP 2022 imagery just became publicly downloadable (superseded by the 2024 flight).
NVIDIA DGX Spark puts 128 GB of unified memory and 4 TB of SSD in a desk-sized AI workstation for the first time at $4,800.

Delivered turnkey

One-time · Install, setup & training — $2,950 one-time
Server provisioning (Ubuntu, full stack deployment), private Tailscale network setup with secure remote access from your phones and desktops, Hermes agent configuration with chat and web interfaces, DRAPP imagery ingest and validation, and two live training sessions so your team runs it on day one.

Monthly · Support subscription — $295/mo · cancel anytime
Remote support and maintenance over Tailscale, security patches and model updates, imagery refresh when new DRAPP releases go public, extraction-pipeline tuning, and priority response. Your data still never leaves your building — support rides the same private network.

Recommendation: approve the NVIDIA DGX Spark build with turnkey install and training — first-year all-in ≈ $11,290 ($4,800 hardware + $2,950 setup + 12 months support). Payback against retired cloud spend is measured in months, not years.
