Re: [OSM-talk] Is it technically and legally possible to add the Open Location Code to the OSM search?
Probably it is done so that plus-codes are known to local actors? Perhaps, local conditions differ from European ones to the degree that it is difficult to comprehend without being part of local community?In any case, I actually tried once to pass a location over telephone by telling the coordinates. It was accepted as a joke. No surprise, since there are different formats, negative numbers, etc.Best regards,O.Sent from my Huawei Mobile Original Message Subject: Re: [OSM-talk] Is it technically and legally possible to add the Open Location Code to the OSM search?From: Michael Reichert To: Vao Matua CC: openstreetmap Hi,Am 2018-08-09 um 22:48 schrieb Vao Matua:> The Tanzania Development trust has calculated the Plus Code addresses for> 17 million building points in Tanzania and have added a sample village> (1800 points) as a test.> https://www.openstreetmap.org/changeset/59213224> > The Python code on Github works great to calculate Plus Codes.> > We did used these tags:> addr:pluscode:full (the 8+2 digit full Plus Code)> addr:pluscode:area (the first 4 digits of the full Plus Code which is a 1> degree by 1 degree lat long area)> addr:pluscode:local (the second 4 digits + last 2 digits which used with a> local name becomes the local address)There is no need for this data in OSM because the data can be retrievedautomatically from latitude and longitude (plain coordinates) which arealready assigned to anything which has a location on the planet.Adding Plus Code tags to OSM objects is as useful as adding latitude=*and longitude=* or any other coordinate system which can be calculatedfrom latitude and longitude.This import should be reverted.Best regardsMichael-- Per E-Mail kommuniziere ich bevorzugt GPG-verschlüsselt.

[OSM-talk] Is it technically and legally possible to add the Open Location Code to the OSM search?
Open Location Codes are also referred to as "plus codes". Since August 2015, Google Maps supports plus codes in their search engine. The algorithm is Open Source, licensed under the Apache License 2.0. and available on GitHub [1]. A plus code, can be generated at: https://plus.codes/ . It can be entered at the Google Maps search input box to find a location. A plus sign "+" is inserted in the code for recognition. It would be nice to have an interoperability. For example, a customer uses Google Map, but a dispatcher in a Call Center the OpenStreetMap. The OLC has got some interesting features: "Open Location Codes are derived from latitude and longitude coordinates, so they already exist everywhere. They are similar in length to a telephone number -- 849VCWC8+R9, for example -- but can often be shortened to only four or six digits when combined with a locality (CWC8+R9, Mountain View). Locations close to each other have similar codes. They can be encoded or decoded offline. The character set avoids similar looking characters, to reduce confusion and errors, and avoids vowels to make it unlikely that a code spells existing words.The Open Location Code is not case-sensitive, and can therefore be easily exchanged over the phone."

Re: [OSM-talk] Addressing systems (Was: Paper/Article about stagnation in OSM)
I understand what you mean and I share your view. I would like just to mention that the European civilization absorbed others' achievements massively.For example, corn ended for good famines in Europe. At the same time, it was the product of five thousand years selection effort by people of South America. Or Hindu-Arabic numerals, or coffee from Ethiopia, the list is very long.Perhaps, it is still possible to co-develop without interference. Perhaps, by creating the new open source address system, we get the feedback and improve our obsolete 18th century address system too.Best regards,OleksiySent from my Huawei Mobile___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Paper/Article about stagnation in OSM
Hi, I read the whole article. I agree with the author's main idea, - software development and implementation has got the invisible social undercurrents, which are as important as the technical issues. By the way, it is true for any human endeavor . Speaking of database structure, - I am thinking about creating a notion of an address. More than half of the planet population does not have addresses because streets do not have (and will never have) names, houses do not have numbers, etc. Besides, in some areas addresses are unstable due to various socioeconomic reasons. At the same time it is possible to create 208 billion of 8-letter unique quasi-words with 26 letters of English alphabet (26 in the power of 8 = 208827064576). Even more if numbers are included. It's enough for all dwellings on Earth. It is easy to transmit a 8 letter word via telephone with ICAO Phonetic Alphabet [1]. Then when we call in browser something like: osm.org/?address=hj3u878s or type the unique quasi-word into a search of of the OSM map: the distinctive geo-marker appears at the respective location with the additional information, such as entrance door code, apartment level, etc. There are several commercial projects which attempt to do something similar. And I realize that this approach may fail. However, the path to success is paved with failures. So at least it's worth giving it a try. However, most developers live in stable places where street names did not change from the 19th century. They may not realize that lack of addresses leads to situations where people cannot call police, firefighters, ambulance, etc. In fact they can call but cannot explain where they live. What consequently leads to the social issues such as appearance of alternative criminal "authorities", sub-quality healers, etc. [1] http://aviationknowledge.wikidot.com/aviation:nato-phonetic-alphabet Best regards, Oleksiy ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] the new icon for the Tag:amenity=bureau_de_change

[OSM-talk] the new icon for the Tag:amenity=bureau_de_change
As far as I understood the new icon for the amenity=bureau_de_change tag will be the one seen on this page: https://github.com/gravitystorm/openstreetmap-carto/pull/3301 It is an icon with the symbols of the US dollar and Euro. (there is still no icon at the wiki page: https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dbureau_de_change ) I suggest instead of an icon with the symbols of the US dollar and the Euro to use a generic icon. For example, similar to this one: https://thenounproject.com/term/currency-exchange/29456/ There are 180 currencies recognized as legal tender in the world [1]. I have nothing against USD and EUR, but why not to use a straightforward comprehensible generic icon, which covers all existing and future circulating currencies?

Re: [OSM-talk] finding drinking water with an Android app
I wrote a web application http://ausleuchtung.ch/travel_pack/ where one can select amenity=drinking_water from a drop-down list with icons, then click on the OSM map and the found drinking water will be show with the geo-markers also with the icon 10 km (or less) around the click. You can also click on the geo-markers to see the complete info and view the images from the Wikimedia 500 meters around the geo-marker. I usually use this web application well before a travel to see the info on the big 4K computer screen. And later, on the ground, I use a mobile app, already knowing what to expect. Best regards, O.

Any simple open source map displaying locations of some objects would also be great - it should be fairly simple to adapt. I know that there is a search function in MAPS.ME allowing to find drinking water, I am currently using it but this app has long startup time and search is really slow for some reason (even for cases that should be easy to index). I found https://github.com/icechen1/TakeABreak/blob/master/README.md - but it is not displaying any locations and Google maps used as a map display and on top of that licence seems to be missing so it is useless as a base for anything. There is a great "OSM peak finder" app, https://play.google.com/store/apps/details?id=eu.wuwer.osmpeakfinder=en_GB - but source code is not available. ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Remote Sensing / DOP / DIY people
Hi Simon, The well known German company Lufthansa Technik offers different training courses in the domain of drones [1], including the excellent basic free online course (Kostenlose Basisschulung). After this course one may try to pass an online exam and receive a certificate. I passed this exam, and here is how this certificate looks like [2]. There are certainly understandable limitations for unmanned aircraft usage for numerous good reasons. However, there are usually mechanisms of getting a permission for a certain flight mission. The authorities take into account the aircraft type, weight, characteristics, safety record, pilot's qualification, timing, purpose, etc. What is important to realize is that by doing a work in the airspace one becomes an integral part of the aviation. And there are certain rules in the aviation which are to be studied and followed. If there is a serious organized approach, I do not think that it is impossible that a silent electric mapping glider with the weight of 1 or 2 kilograms could be allowed to fly over urban areas at the altitude of about 100 meters early in the morning, from time to time. For those who know German language the Lufthansa Technik online training course would be a good starting point. I takes just several hours to complete.

Some are capable of cm accuracy but does OpenStreetMap benefit from this? I'd explicitly exclude the legal aspects. Yes - Its complicated. Actually in Germany it is really simple from a legal pov: you can't fly (in a practical sense of the word) anywhere that is remotely interesting for OSM. Unluckily: no smilies. Simon Its not the accuracy i am aiming for - in Germany at least in most areas have pretty good Aerials. The problem is that those images are from the public sector and it will take up to 5 years for them to be accessible/available. I am aiming for lower latency ;) You see a new development area and it'll take up to 5 years to be able to add houses etc. So it would be nice to take aerials every 6 Months of those areas and follow the build up of new houses.
