Yeah, I was trying to get a locally stored image to display but obviously unsuccessfully.

Responding to suspicious changes about 1 month ago

Mapbox mappers complaining about "suspicious changes"?

Oh, the hypocrisy.

Mapbox needs to concentrate on improving their own editing before criticizing others. I've spent far to much of my OSM time contacting them about their dubious edits.

Why not join in on the community forum so you can ask for yourself & so find solutions to your queries on this collaborative project?

Please have a read of this:

https://lists.openstreetmap.org/pipermail/talk/2016-August/076596.html

Specifically:

"Is geospacial mathematics is resource intensive?"

"Not at all. Nominatim happily processes boundaries and always prefers it over any other hierarchy information."

"As soon as there are boundaries, multiple candidates don't happen anymore, so that is_in:* is ignored for all practical purposes."

"Yes, if possible always draw boundaries. They are more precise and easier to maintain. is_in is unnecessary."

Regarding "doing no harm" please read this post regarding your ref:hectare tag: https://lists.openstreetmap.org/pipermail/talk-gb/2016-August/019076.html

Hi

  1. Computers are very good at geospacial mathematics

  2. Where does it say Nominatum uses is_in rather than boundaries?

Similar to your assertion that boundaries shouldn't be be attached to other entities because they might change, boundary lines often get amended. Using the hard coded is_in tags means the entity will become inaccurate.

Hi Alex

is_in:* is redundant when boundary=* is used. OSM is geospacial. Mathematics can be used to determine if one area is within another.

Potlatch 2: quickly move from task to task 9 months ago

Ah, don't worry, I forgot that Overpass, for some reason, converts OSM to Geojson differently depending on whether the Turbo site or osmtogeojson is used. I deleted the unnecessary nodes & it works fine.

Thanks for a great utility.

PS woops. How do I post prettified code here?

Potlatch 2: quickly move from task to task 9 months ago

Hi Thanks for this. Looks like it could be useful, except:

of geojson file { "type": "Feature", "id": "node/-631", "properties": { "type": "node", "id": "-631", "tags": { "name": "Keynsham Masonic Hall", "addr:postcode": "BS31 1SR", "businesstype": "Other catering premises", "addrline1": "99 Bath Road", "addrline2": "Keynsham", "addrline3": "Bristol", "addrline4": "Bath And North East Somerset", "addr:housenumber": "99", "addr:street": "Bath Road", "fhrs:rating": "5", "fhrs:authority": "Bath and North East Somerset", "fhrs:id": "205662", "fhrs:inspectiondate": "2012-06-18" }, "relations": [], "meta": {} }, "geometry": { "type": "Point", "coordinates": [ -2.485158, 51.412579 ] } },

It jumps between locations, but doesn't display the name tag: Task dialog

Any ideas?

It's a shame you've detailed what you think is there just to make it look pretty instead of what's actually there on the ground.
