Scouting Public Land with Satellite & Topo Maps

Use satellite imagery, USGS topo and KML/GPX downloads to e-scout refuges and WPAs before you go.

Public-land hunting rewards the hunter who knows the ground before opening day. Every refuge, hunt unit and WPA page on WildlifeChase includes an interactive map with four basemaps and downloadable boundaries. Here's how to use them to e-scout like a pro.

The layers

  • USGS Topo — U.S. Geological Survey topographic basemap with contour lines, water, wetlands, roads and trails. Best for terrain: ridges, saddles, drainages and benches.
  • Satellite (USGS) — public-domain aerial imagery. Great for vegetation and water.
  • Satellite + labels (Esri) — high-resolution imagery with place names and roads.
  • Streets (OpenStreetMap) — road names and access routes for planning your drive.

Overlays show hunt units by status, FWS-owned land, the approved refuge boundary and private easements. Click anywhere on the map to get GPS coordinates and a "navigate here" link — handy for pinning a parking area.

What to look for

Waterfowl

  • Water that's actually holding this year — shallow sheet water and flooded timber show dark on satellite.
  • Sanctuary (closed) units next to open units: birds trade between them.
  • Grain fields within a few miles for field-hunting opportunities on adjacent land (with permission).

Deer and big game

  • Edges where timber meets grass, crop or marsh.
  • Funnels and pinch points: narrow strips of cover between water and open fields, creek crossings, saddles on topo.
  • Distance from roads and parking — the farther from easy access, the less pressure.

Upland birds

  • Dense grass and cattail edges on WPAs, especially near food plots or crop fields.
  • Shelterbelts and thermal cover for late-season pheasants.

Take the boundaries with you

Each refuge page offers KML, GPX and GeoJSON downloads; county pages offer KML/GPX for all WPAs in the county.

  • Google Earth (desktop or web): File → Import the KML to see units in 3D.
  • onX Hunt: import KML/GPX through the onX web map to add units as markups.
  • Gaia GPS / CalTopo: import KML, GPX or GeoJSON as a layer or folder.
  • Garmin handhelds: load the GPX waypoints with Garmin Explore or BaseCamp.

A 10-minute e-scouting checklist

  1. Confirm the unit is open for your species and dates.
  2. Check closed areas and private inholdings along your route.
  3. Find legal parking and access points; note gate and road closures.
  4. Mark two or three setups based on wind direction (check the 7-day forecast on the page).
  5. Save coordinates and download the KML/GPX.
  6. Check shooting hours for your date in the sun table.

Boundaries are digitized from official data but can be off by a few meters. Posted signs on the ground always take precedence.
