Re: [OSM-talk] Examples of good paid mapping?

[Oleksiy Muzalyev]

Good morning,

I agree that the existing tags are to be used. And they should be used 
correctly, as it's described in the wiki. It is applicable not only to 
professional but also to hobby mapping.


I think that it makes sense to survey objects before mapping by 
physically visiting them. During a survey one can record the GPS traces 
around the object of interest. It could be done with a dedicated GPS unit.


A modern GPS unit is capable to record traces for 24+ hours without 
interruption. So even the approaching roads (or railroads) could be 
traced. Having these traces in a map editor will let us see that the 
satellite images are aligned correctly, or to see if the satellite 
imagery outdated and what is not on it yet.


It is also possible to make some ground and aerial (oblique & vertical) 
HD  photos of the object from different angles during survey. And not 
only of the building itself, but also of other POIs around such as say 
bus or tram stops.


Having the photos from the survey would allow to add later the building 
levels, opening hours, bus stops names, etc. It is possible to upload 
the best selected photos to the Wikimedia or Flickr (after blurring 
vehicle registration plates and faces on them for privacy) and publish 
the corresponding links on the OSM map, so that other mappers can use 
these images too. Before uploading photos, the GPS coordinates can be 
added to them automatically from the recorded GPS trace.


Another big survey topic is the elevation [1]. Human settlements are 
usually located near water. It could be of interest to know if an object 
is above or below the water level of a nearby sea, lake, or river, since 
the risk of flood could be evaluated. However, measuring an elevation 
with an altimeter [2] is not as simple as it sounds, but it is doable.


My point is that the good mapping, both amateur and professional, could 
involve not only mapping via the satellite imagery, but also the 
on-the-ground surveys using such modern tools as the dedicated GPS 
units, ultra-light quad-copters, portable HD photo-cameras, altimeters, 
etc. Sometimes it is not possible to understand from the vertical 
satellite image, seeing only the rectangle of the roof and the shadow, 
what the object is exactly, how many levels it has, what additional 
features or services it contains. Besides, the satellite imagery in some 
areas could be outdated or misaligned, and a survey also helps to 
understand to what degree, so that we use it properly.

Have a good day!

How to be successful:

В Listen to osm experts/community and not fight against them

Use existing tags on the wiki, don't invent your own

Verify data accuracy as muchВ as you can, not dump data

When merging data, verify if data is older than yours, locals usually 
have a better sense of what buildings/pois have been demolished/exist

Except that - because they do it right - they will of course have
documented their work on the wiki.

Exactly. When companies do it right nobody knows they’re doing it.

Most companies are doing well, and get along well, we just only hear about the 
problems. So it’s probably not this or that company to highlight, but 
particular mapping projects that illustrate well how it’s done.

Great question, Michał!

I've been paid by clients to both map in OSM (so the database is consistent 
with my client's expectations at the same time it is "correct" according to OSM 
community standards) and using OSM to make a map (a map product that was 
included in a published book, for example).

I'm 100% in agreement with James:  listening to the greater OSM community 
(along WITH your client's needs) is paramount, lest your edits get redacted.  
Use existing tags:  reading wiki and sampling existing data with taginfo or 
Overpass Turbo queries can go a long distance at researching "what is" in OSM 
(perhaps rather than what you might "wish to be").  If what you do can be 
considered an import or entering new data (most paid gigs are exactly that, 
while some smaller set improve existing data), DO verify accuracy on existing 
data to the greatest extent practical, best to do so both before and after your 
work.  Actively seek and implement high quality (top-level precision, 
thoughtful, careful, community-accepted accuracy in tagging, keeping any 
required / expected communication or status reporting frequently updated...) 
throughout the project.

Small consultancies like mine that do "paid mapping" might not seem an obvious 
best source to ask this, but as our answers resonate with "excellent work, pays 
attention to quality..." we really do "lead by example," however minor our 
efforts may seem.  Bigger companies and tech giants that use or intend to use 
OSM:  please respect our community (and its standards and practices) first and 
foremost.  You are welcome — though, everybody appreciates respect.  As is true 
in many endeavors, it takes a long time and is challenging to build up a good 
reputation, which is easily harmed by foolish, anti-community blunders, so 
avoid these!  Finally, when in doubt, seek consensus:  plenty of community 
wants to help make a better map, but only with agreement does that happen.

[OSM-talk] Examples of good paid mapping?

[Michał Brzozowski]

Hi all,
Do we have any examples of companies that do paid mapping (preferably at
scale) and do it right?
Maybe leading by example will help other mapping teams get along better
with local OSM communities?
