MappSmith — River builder

• Are roads shown for rivers outside the US, Canada, the UK, Australia and New Zealand?

  Water and contour lines show everywhere. Roads and woods come from our own map, which covers the US, Canada, the UK & Ireland, Australia and New Zealand, so a river in any other country shows its banks and contours with no roads.

• Can I turn pieces and marks off?

  Yes, all of them. Under Details, every layer can be switched off: the water sheet, the raised plaque, the frame, tributaries, other lakes and ponds, contour lines, roads, local streets and woods. So can every mark: rapids, put-ins and ramps, bridges, dams and falls, fishing spots, towns, their na...

• Can I use my own float or paddle from a GPS file?

  Yes. Under River, choose GPS file and drop in a GPX, TCX, KML or GeoJSON file from your watch or app. The file is read in your browser and never uploaded. Your track becomes the stretch, the builder finds the river under it, and the date of the trip fills in the line under the name.

• How do I make a river map?

  In the Layers panel, set Product to "River". The river builder opens. River: tap a famous stretch, search any river by name, or drop in a GPS file of your float. Stretch (for a river found by name): drag the two handles along the river, or pick the ends by town, ramp or dam. Look: choose River i...

• How wide is the river on the board?

  Wide enough to read across a room: a blue ribbon about 2% of the board's short side (Wide, Medium or Fine, or set it exactly under Fine tuning). Where the riverbanks are mapped and wider than that, the river shows its real banks, so wide pools, braids and the lakes it runs through keep their shap...

• What do the five looks give me?

  River inset: the land in wood with the river cut out of it and a blue acrylic (or painted) sheet underneath showing through, roads and contours engraved on the banks, and a raised plaque. River raised: a wood board with the river standing on it as one blue piece, tributaries and all, and the pin ...

• Where do the rapids, put-ins and bridges come from?

  From OpenStreetMap: rapids (with their whitewater grade where it is mapped, shown as Class III and so on), slipways, canoe put-ins and take-outs, fishing access sites, bridges where they cross the river, dams, weirs and falls. Some rivers are mapped in great detail and some hardly at all. The bui...

• Which rivers can I find?

  Any named river on OpenStreetMap, worldwide. Rivers are long, so after you pick one you choose the stretch: drag the green and red handles along it, or pick its ends from the towns, boat ramps, put-ins and dams along the river. The famous stretches (the Madison from Quake Lake to Ennis, Paradise ...
