App Guide

Overview

The TrueTopo app is a web-based map focused on Alaska land intelligence. It runs in the browser with no installation. You can use it on desktop, tablet, or mobile. A PWA-capable version supports offline use for Pro subscribers.

The narrow rail on the left opens task panels. Relevant to billing:

Data — Summary of what’s on the map and catalog links
Basemaps — Base map only (topo, satellite, etc.)
Presets & layers — Quick presets and the data registry (layer toggles). Locked groups follow your expansion packs & pricing entitlements.

The right sidebar contains panels you can open and close. Each panel serves a specific purpose.

Panel	Purpose
Layers	Toggle map layers by group (mining, ownership, access, etc.)
Dashboard	Gold/silver prices, diesel, elevation at cursor, daylight, filing deadlines
Intelligence	Opportunity Score, prospectivity, access, legal status, recommendation
Analysis	Terrain tools, slope analysis (Pro), measurement, export
Tools	Route import (GPX/KML/GeoJSON), elevation profile
Settings	Basemap, theme, shortcuts, Pro features
Claim Portfolio	Watchlist and claim tools (Miner Kit)
Compliance	BLM/DNR compliance tracking (Miner Kit)
Field Log	Waypoints, photos, notes for fieldwork (Field Kit)

Some panels are gated by expansion kits or Pro. See Expansion packs & pricing and Account & Billing.

Basemaps

Choose a basemap to set the visual foundation of the map:

Topographic — Terrain with elevation shading
Satellite — Satellite imagery
Terrain — Shaded relief for slope context
Light / Dark — Minimal styling options

Basemaps are configurable in Settings or via the basemap selector.

Layer groups (90+ layers)

Layers are grouped by theme. Free (Base) layers include:

Group	Contents
Mining	State claims (active/pending/leasehold), federal claims, prospecting sites
Ownership	ANCSA conveyed/selected, Native allotments, federal/state/private, withdrawals
Reference	PLSS, recording districts, GNIS, Natural Earth
Environment	NHD hydrography, 3DEP elevation

Expansion packs and Pro add:

Group	Pack	Contents
Access	Access Pack	RS2477 trails, 17(b) easements, DOT roads
Easements	Easements Pack	DNR easements, BLM 17(b), land activity
Infrastructure	Infrastructure Pack	Power lines, pipeline, fiberoptic
Fish Pack	Fish Pack	ADF&G fish counts, USGS stream gauges
Mineral Intel	Mineral Intel Pack	MRDS, ARDF, geochemistry, geophysics, mineral belts
Geology	Mineral Intel Pack	Bedrock geology, faults
Aviation	Pro	Airstrips, runways, aerodromes
Marine	Pro	Coastal and marine layers
Discovery	Pro	LiDAR, satellite imagery layers

See Layers for detailed layer reference.

Tools

Route import and elevation profile

From the Tools panel, import a route file (GPX, KML, or GeoJSON). Supported sources include CalTopo, Garmin, onX, and other mapping tools. Select a route to compute an elevation profile (distance vs. elevation, gain/loss).

Measurement

Use measurement tools (when available) to measure distances and areas on the map.

Export

Export features to KML, GPX, or generate legal descriptions and filing packets for claims.

Opportunity Score

When you click a point on the map, the Intelligence panel computes an Opportunity Score:

Prospectivity (0–10) — Minerals, geology, nearby deposits, expired claims
Access (0–10) — Roads, trails, RS2477, 17(b) easements
Legal (0–10) — Land status, claim overlap, Native land

The overall score and recommendation (Stake / Investigate / Monitor / Avoid) help you decide quickly. All computation runs in your browser using live data from BLM, DNR, USGS, and DGGS.

Keyboard shortcuts

Common shortcuts (configurable in Settings):

Search — / or Cmd+K / Ctrl+K
Layers — L
Settings — , (comma)

Offline (Pro)

Pro subscribers can enable Offline Mode. The app downloads selected layers to IndexedDB and continues to work when there is no network connection. Essential for field use in remote Alaska.
