Lodeline

Lodeline shows USGS 3DEP LiDAR terrain and a plain terrain-favorability read for spots you care about. Snap a geotagged photo or drop a pin. Lodeline pulls bare-earth elevation for that location and scores how much the ground resembles classic collector terrain: drainages, benches, and low spots. That score is favorability, not a mineral detector. Lodeline never claims to find gold and never shows a dollar value of gold. ASK THE AI GEOLOGIST (LODELINE+) Drop a pin and get a field briefing grounded in public records: nearby historical mineral occurrences from USGS data, host-rock context, and drainage reads. Follow-up questions stay on the same spot. Lodeline+ is an optional auto-renewable subscription for server AI features. WHAT YOU GET FREE - Photo or pin to LiDAR terrain to favorability score - Contours, roads, public-land status, and the PLSS grid - Waypoints (up to 50), trips, GPS track recording, and a dig log - UTM/MGRS coordinates and a sun-legible dark map LODELINE PRO (ONE-TIME PURCHASE) - Historical mineral-occurrence overlay from USGS records - Active-claims check via official BLM records links - Offline packs for no-signal country - Elevation transect and unlimited waypoints LODELINE+ (OPTIONAL SUBSCRIPTION) AI Geologist and Area Intel run on our servers as Lodeline+, an optional subscription. Skip it and you still have a complete field toolkit. Lodeline Pro remains a separate one-time purchase. REAL SCIENCE. STRAIGHT ANSWERS. Lodeline scores terrain favorability from public government data and shows its work. Historical mineral records are history, not active claims or proof of gold: always verify land status and get permission before you dig. Your photos stay on your device unless you attach one to an AI message.
