OpenStreetMap Data Quality Assurance Tool

askja's Issues

Region - paginate/group by subregion if too many

More than around 1000 settlements in a list is fairly cumbersome.

Settlements - naming quality

Publish a list of places with lowercase, UPPERCASE names.
Places that are in a similar area and carry same names (radius).
Places who are pretty much just "village" in different languages (Turkey examples)

Advanced tasking manager

Tailored to each user, per region.
If user has no experience in a tasking area, then present the guidelines in a more robust way, make it optional for an experienced contributor.
Tasks are broken into several areas:

1. draw road
2. classify road
3. draw only buildings
4. mark settlements with a point

Settlement - link to HOT task / MapCraft

If there is a task for the settlement in the HOT Task Manager then make it possible to add link.
Similarly for MapCraft?

Help regarding the project Quality Assurance tool for OpenStreetMap for gsoc 19

Hey,
I am interested in contributing to your project under OSM for gsoc 2019. I will be glad if you can guide me on how to proceed with contributing and submitting any evaluation test before going any further.

QA: Flag issue if sudden drop from green to red status

Generally a human is needed to flag something green.

If a settlement has buildings (yellow for automater, upgraded to green by human) but then on the next check has NO buildings then that needs to be flagged. There are possible reasons for it (earthquake, tsunami, volcano etc) but there could also be some vandalism behind that.

Similar for amenities, paths etc.

Data quality section

Lists the duplicate names, ALL CAPS, no names, non caps, digits etc.
Also show flagged settlements

QA - the squaring problem

There is a python script that downloads a requested bounding box from Overpass, checks for all 4 point buildings that are not square (different length of lines) and from that you can grep username.

Make a user friendly interface for it, for advanced mappers, compiling number of buildings in a particular area/district. Making it easy for adv. mapper to send a message to tell them about squaring shortcut in editors and to look over their work.

Allow sort or filter in Settlements page

Especially in larger lists, it might be practical to filter out places of a certain type. Might make it easier to filter out top priority tasks. Or maybe sort by default, so places with the biggest problems show up first.

Show value of icons onmouse over would be handy too.

Settlements - collection

Be able to create a collection of settlements, for example settlements that belong to a single HOT task or Missing Maps task.
Collection can be shared with others.

Mapillary API v2

Need to update to use Mapillary v2 API

POI musings

This requires a well defined area, it will work in places like Kópavogur or within its defined neighborhoods, counting POIs and types, like shops etc, cache it and count again later and track changes.

Another POI possibility would be to add a special tag to a POI, like osm_contact: [email protected] , then if the node has not been updated in a year send (bulk if many nodes with same osm_contact) a generated e-mail, listing the POI and links to them on the map and a uniquely generated link that allows them, in a simple interface, to update data.

For example:

• Marking it has closed
• Updating the address
• Fixing opening time

The interface could then either update the database in case of simple fixes (opening time), perhaps delete node if it closed.

If it has moved then we can try and do a lookup and present a pin on a map and ask "Is this the new location?", if not and we can't find new address then we put it on a microtask list that can be looked at, or put an OSM Note on it.

Task: 3d mapping

If a place has buildings mapped, without 3d tags (roof:shape for example) but has Mapillary images, point it out as a possible 3D mapping project.

Settlement - next and previous

Add a feature to each settlement that allows to navigate to previous and next settlement within subregion and/or region.

Mapillary API

Ask if any Mapillary image within 500 meters of settlement node.

Traverse through all Unknown (and No images as option) and mark Partial if an image is found or No if no image is found.

Settlement - comments

Enable comments on settlement pages, for example if there is a 3rd source of imagery - other than Bing and Mapbox.

Settlement - Wikidata and Wikipedia links

Publish Wikipedia link if one exists.
Link to Wikidata item - anything that can be pulled back from Wikidata?

Settlement - code red button

Show only if logged in. If pushed sets all currently unknown options to red status.

Please add the Philippines

Can you add my country? I will be happy to curate and manage it.

Settlements - update using bot - set to red or yellow

Read from overpass cache, update values for grey (option: red) (unknown, bad/no) icons.

Login window blank for some people

Popup for OSM Oauth login feature is blank for some people, loads slowly for others.

Replace with a button like login - requiring no popup.

Settlements - faster switching between regions

Search by co-ordinates

Be able to enter co-ordinates into search window (radio toggle between name/co-ordinates) and get list of nearest settlements.

Settlement - Favorites

A user can favorite a settlement and then gets notices on his user page (e-mail option?) when it has been updated. For example if it has bad imagery and sometime later it is updated with good imagery.

Settlement - changelog

Show last time changed, users that have modified evaluation

Settlement - flag for issues

For example if it seems to be a duplicate node, next to similar node.

User page - Browsable history by year/month/week/day

Maybe statistics per country, region, subregion as well

Imagery evaluation

Something similar to http://crowdmap.geog.uni-heidelberg.de/app/missing_maps/task/22425

Features:

• Pick countries
• Add keyboard shortcuts, 1-Good, 2-Partial, 3-Bad
• Be able to add place to favorites
• Show tiny overview, country with a pin?
• Add to frontpage

Settlements - filter by icon status

For example show only good imagery, decent imagery, bad imagery or unknown

User activity on front page

Too slow, SQL using too much time sorting and copying to tmp table

Switch to OAuth 2

Switch to OAuth 2 from HTTP Basic Auth and OAuth 1.0a. They are being deprecated.
See openstreetmap/operations#867

Note, api.openstreetmap.org API url currently can not do OAuth 2 handshake. See openstreetmap/operations#951 (comment)
You can split the www. base URL and api. API url. See osmlab/osm-auth#123 (comment)

Settlement - find closest settlements

Useful when evaluating imagery, to jump to nearest settlements.

Home village

Being able to mark a settlement as your home.
Be able to say if you know someone that lives in another village.
Not visible to the public, but able to say "1 contributor lives in this village".
Able to send a message to contributor in said village, anonymized?

Settlements - ask Overpass

Ask for highway, path, amenity, building, addr: within a 500m radius of settlement node.

Expand about page

The about page only shows icons used in the "farms/estates" project.

Settlements - provide a list of unnamed settlements, subregion, region and lat/lon

Making it easier for data QA people to dig up from local sources.
