Be able to show a map of ticks / ascents / routes (any facet filter) eg embed on profile

[brendanheywood]

Could be recent ticks or perhaps easier to implement a marker for every crag climbed at with bigger equals more ticks

We currently have the Notable Ascent by crag table, which is good but loses so much info. What we want is a simple glance which show all the places in the world that a climber has ticked at, and show both the volume and difficulty of climbing they have ticked there.

Because this is potentially going to have lots of dots of color around the place, I'm thinking of making this a static grey scale map so the colored markers are more prominent. This also avoid loading google maps and will result in a much more performant page. It will also be easier to responsive and useful and smaller size. If you click on it you get taken to a facet page with more details but that's out of scope here.

• [ ] static world map, responsive svg
• [ ] pass in an array of records, each with a zindex, a color, and size
• [ ] if there are 2 crags each with 20 easy (green ticks) and 10 hard (red) ticks, then there will be two green circles with smaller red circles inside them. If the green circles overlap, the red one sit on top. ie green will never overlap red.
• [ ] the visual size of the circle isn't perfectly linear. The radius of each circle is the cumulative square root of each layer. ie if one circle is just 100 green ticks, then the radius could be 10 (10 * 10 = 100). But if there are 50 green ticks and 50 red ticks, the total circle size starts at root(50 + 50) = 10, green = 10, but then the red circle is root(50) = ~7 on top. Also there is a minimum size to every dot, probably just a fixed addition to the radius to make small ticks more visible. This won't really visually affect large dots.
• [ ] this same template should be able to be use in different contexts, ie on the home page showing crags around the world
• [ ] I think the data should be simplified in some regard first, or possibly the template can normalized the data, so that two very close crags will be merged. This won't be a full on clustering algorithm, just rounding the lat / longs to a fixed low precision.
• [ ] optionally show a number in the circle. This could be the total number of ticks / routes / photos etc
• [ ] it will be in the same Mercator projection as google maps which makes the maths easy, but we will aggressively crop out the north and south regions

Probably use this as a base:

Even thought this particular map will be static, I want to have the algorithm for circles sizes well documents as I'll also use it in the clustering algorithm when we redo the dynamic google maps.

Template data should be a simply format that we can reuse for ticks / routes / photos or whatever.

[
  [id: 12345, lat: 123.233,  long, -180.234, values: [0, 10, 15, 1, 0],
  [id, 23456, lat: 103.138,  long, -182.531, values: [0, 12,  9, 4, 0],
]

In this case the 5 values will correspond to the 5 grade bands, but in other contexts there may only be a single band. The colors to be used will be in provided in the calling template.

Wow, that's quite an old issue.

Underlying data source would be a new crag based summary facet https://github.com/theCrag/website/issues/2120

The second piece and even more important feature for a user like me (living in Switzerland and thus with >100 crags with a 2h radius) is to explore crags that meet some of my basic climbing requirements (similar to the example above). I couldn't find such function. I can search and get results in the country/region but then when I want to see where all the different crags that meet my criteria on the map I can't. The search seems to get even discarded when switching from search to map (see pain point described above). This makes finding a crag that meets both some route and geographic characteristic quite impractical for people that have a wide choice of crags.

Displaying the map of your own ascents is a nice gimmick - but it doesn't have that much value. There is no real need to come back for the ascent map frequently once you have seen it.

Having the same kind of map view for your search results would be a game-changer, though. Ideally, it would be possible to combine route and area search in one query, e.g

Show me all crags/routes with orientation north that are kid-friendly where there is sport-climbing up to grade 6c.
