Map, layers & boundaries

Changing the map type

1. Tap Layers in the bottom bar (on desktop web, the Layers button in the right-hand column).
2. At the top of the sheet, under Map Customization, swipe through the map types.
3. Tap one: Street, Terrain, Satellite, Lidar or Ocean.

The sheet closes and the map redraws. The map type is the background; every layer you have switched on — trails, boundaries, points of interest — draws on top of it and stays on when you switch.

Note: All five map types are free.

Turning layers on and off

Tap Layers. Below the map types, layers are grouped: Waterways, Trails, Boundaries, Points of Interest, Terrain and Overlays. Tap a group to open it, then use the switch beside a layer.

• The text on the right of each group — Off, 3 of 12, All on — tells you how many of its layers are showing without opening it.
• A Pro chip in place of the switch means the layer is part of Trailmonger Pro. Tapping it shows the plans.
• A signal icon marks a layer that is live and needs a connection, such as Active Fires or the Temperature Map.
• A greyed-out row means that layer’s data is not available right now.

Some layers show extra controls once they are on. Rivers & Streams lets you hide small or unnamed streams. Contour Lines has an interval, a line colour and an intensity. Cell Coverage lets you pick carriers. The Trails group has chips for trail type and a Hide unnamed trails option.

Seeing public land and other boundaries

Tap Layers and open the Boundaries group. Each kind of land is its own switch, so you can show only what you care about:

• US States and US Counties.
• BLM Lands, National Forests and Other Federal Lands (parks, refuges, military and so on).
• State Lands, Tribal Lands, and Local & Regional lands.
• Marine Protected Areas and Ski Area Boundaries.
• Hunting Units — when it is on, choose In view to show only the states on screen, or All states.
• Property Parcels, which is part of Pro.

Tap a hunting unit, a marine protected area or an active fire on the map to open its details.

Note: Being able to reach a piece of land on the map is not the same as being allowed on it. Check the managing agency’s rules before you go.

Property lines and owner details (Pro)

1. Tap Layers, open Boundaries, and switch on Property Parcels.
2. Zoom in until the lines appear, then tap a parcel.

The parcel card shows the owner (where the state publishes it), address, parcel number, size and location, with a View county record button where one is available. Use Save this place to keep it in your favorites.

Parcel data is not available everywhere yet. Outside the covered states, the map shows a notice listing where it is live.

Note: Searching for an address shows that property’s boundary and size on any plan. The owner name and parcel number are part of Pro.

The lines are the ones county assessors publish for mapping — a strong reference, not a legal survey. See how accurate the property lines are in the FAQ.

Checking the weather

Tap the Weather tile at the top right of the map. It shows conditions for the area in view, so move the map first if you want somewhere else.

• On every plan: today’s conditions, the hourly forecast, and the forecast discussion.
• With Pro: the extended daily forecast and live NOAA Doppler radar.

For weather drawn on the map itself, open Layers → Overlays and switch on Temperature Map or Active Fires. Both are free.

Note: If you do not see the Weather tile, open the menu, find Map display, and switch it on. Weather needs a connection.

Checking river flow

1. Make sure Rivers & Streams is on (Layers → Waterways).
2. Tap a river line on the map.

The sheet shows the nearest USGS gauge’s flow in cfs, gauge height and water temperature, with charts for the last 15 days. Tap the heart to keep the river in your favorites, where its current flow shows in the list.

Note: If there is no USGS gauge within 15 miles of where you tapped, the sheet says No Sensor Data. Flow data needs a connection.

Reading a trail’s details

Tap a trail line on the map. The sheet shows its distance, elevation gain and loss, difficulty, an elevation profile, and the average and steepest grade with the high and low points.

• The heart saves the trail to your favorites.
• The share button sends a link to the trail.
• Directions opens directions to it.
• Download Map opens Offline maps so you can save the area around it.

The coloured key on the map explains trail difficulty and type. If you have hidden it, switch Trail legend back on under Menu → Map display.

Measuring a distance or an area

1. Tap the ruler (distance) or the area tool at the lower right of the map.
2. Tap the map to add points — two or more for a distance, three or more for an area.
3. Read the result in the pill that appears. Undo removes the last point; Clear starts over.
4. Tap Save to name it and, if you like, put it in a folder.

Saved distances and areas live in Menu → My Data, where you can open, edit, export or delete them. You need to be signed in and online to save.

Choosing what sits on top of the map

Open the menu and find Map display. Each readout on the map has a switch there:

• Compass, Elevation readout, Scale bar, Weather, Tide readout and Regulations — the tiles at the top right. Use the arrows to change their order.
• Center crosshair and Center coordinates — a mark at the middle of the map and its latitude and longitude.
• Trail legend — the difficulty and trail-type key.

Tapping a tile opens more: the Compass tile opens My Location, Weather opens the forecast, and Regulations opens hunting and fishing regulation links for the state you are in.
