Add your own sites and routes

Import a CSV, GeoJSON, KML, KMZ, GPX or zipped Shapefile; what happens to it.

What you get: Your facilities, routes or areas drawn on the map, and checked against hazards while the map is open.

Before you start

  • A file of your locations. For points, the simplest is a CSV with a header row: name, lat, lon are required; id, type, status, owner and updated_at are optional. Download a sample CSV (three made-up sites).
  • No account is needed to import. Plan limits on tracked sites are described on Plans.

Steps

  1. Choose File → "Import data…" and pick the file. The file is read in this browser; nothing is uploaded.
  2. A CSV of points becomes "Your data" sites; other formats become a layer of their own, named after the file.
  3. Find them in the "Your data" section of the "LAYERS" panel. Each imported layer lists how many features it holds and anything it could not use.
  4. Click an imported feature to see its own attributes.

What success looks like

Your sites appear, drawn violet with a long dash and hollow: the mark for something you supplied rather than something a feed observed.

Limits to know

  • A row with no usable coordinate is dropped and counted, never placed at 0,0. A Shapefile in a projected coordinate system is refused rather than drawn in the wrong place.
  • Imported data is saved in this browser. When you are signed in, your imported sites are also kept on your account and follow you to another browser.
  • Imported data never travels in a share link.

If something is wrong

"No valid rows … Required columns: name, lat, lon."
Check the header row spells the columns exactly (latitude and longitude are accepted too) and that each row has a name and numeric coordinates.
My sites are in the ocean off Africa.
The coordinates were read as 0. Check for empty or text cells in lat and lon.
