About the heatmap / frequently asked questions

The data is currently from 11th September 2020 . The heatmap has records of 1342256 visited tiles.
Where does the data come from?
The data comes from VeloViewer. Specifically data is included in the heat map if
  • A rider's data is set to "public" in VeloViewer
  • A rider is on the max square or max cluster VeloViewer leaderboard for one of selected Strava clubs, including the RideEveryTile club.
  • The data was present on VeloViewer when the heatmap was last updated (approximately monthly)
This means that there *are* tiles that have been visited that are not shown as visited on the heatmap. Maybe you've visited some of them yourself? If so, please consider making your VeloViewer data public
How do I make my VeloViewer data public?
Log into VeloViewer and go to your update page. Click the "Show Options" button. Then click "Share my data with anyone". Then click "Save". Your name will now show up as a clickable link in any VeloViewer leaderboards. This makes it possible for RideEveryTile to access your list of visited tiles and add them to the global heatmap.

VeloViewer update page. Click the "Show Options" button and then make sure the "Share my data with anyone" box is ticked.

What does the heatmap show?
The amount of detail shown depends on the zoom level. At zoom level 12 or higher individual tiles are show. The fill colour of the tile and the outline colour of the tile will always match and shows how easy the tile is to visit. A dark green tile means at least five people have made a ride public that goes to the file. Light green means two to five people have visited. Yellow means just one person. An uncoloured tile means no-one has visited at all. The most "difficult" tiles of all are red - such tiles have been marked as "practically impossible" - meaning that the community collectively thinks there is no realistic way to get into the tile. "Red" tiles are typically enclosed in high security sites like military bases, airports or open cast mines.

If you zoom out, detail about each individual tile is lost and we show information in tile groups. For example at zoom level 10, information is grouped into 3x3 tiles. The fill colour of the tile shows information about the "hardest" tile in the group. So if tile is filled yellow, then at least one tile in the group has been visited by only person but there are no unvisited or impossible tiles. The outline colour of the tile shows information about the "easiest" tile. So a tile group with a dark green outline contains a tile that has been visited by lots of people. To find out information about that tile group, you need to zoom into that area.

Contributing information about a tile

Click on a tile. A textbox will appear on the left-hand side. You can type what you like in there and it will be added to the notes about the tile. Tiles with information are shown with a small red triangle in their corner.

Currently we are manually checking tiles before marking them as "impossible". Apparently marking things as impossible is a good way to ensure that someone goes there soon...
