[HOT] Looking for tagging experts or Humanitarian Workers - Help needed
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello everyone, A farily long explanation below, to just see how you can help, just jump ahead to the end of the email. I am working on an ontology for OSM concepts and tags. An ontology is basically a set of true statements about some domain. These statements can then be read by a program called a 'reasoner' which takes the statements and tries to fill in extra 'inferences' from the statements to get a more complete picture of a domain. Finally, you can then query this model in different ways to answer various questions. For the OSM domain these statements are things like: * A building is a kind of structure * An airplane hangar is a kind of building * A Structure is a kind of real world entity * A building can be tagged with building=yes * An airplane hangar can be tagged with aeroway=hangar * Buildings are of high importance to firefighters Once these 4 statements have been entered into the ontology we can then ask it a question like What tags are of interest to firefighters? The model would then make the following chain of inferences to answer the question: * Since a building is of high importance to firefighters and a building can be tagged with building=yes, then the tag building=yes is of interest to firefighters. * Since an airplane hangar is also a building, and airplane hangars can be tagged with aeroway=hangar, then aeroway=hangar is of interest to firefighters. * Therefore both the tag building=yes and aeroway=hangar are important to firefighters because either of them could indicate a kind of building. Notice that in answering the question the reasoner was able to make several inferences that we didn't have to manually enter into the model. We don't have to manually curate a list of what is of interest to a police officer travelling on foot with a police dog because we can simply have lists of things like what is of interest to a person on foot and what is of interest to a person with a dog, etc, and then just tell the model how to combine them to make the list we are actually interested in. The model can also be used to document things like mispelled versions of tags, different schemes for tagging the same real world concept, and even things like tags entered in foreign languages if they exist in the database. It will therefore be very useful for things like designing stylesheets, writing validator rules, creating custom osm2pgsql schemas, creating routing rules, and so forth. So what do I need from the community to make this all happen? Although I can quite easily go through and enter this kind of information into the model myself, actually figuring out what to enter is a difficult process once you get past the obvious stuff like roads and buildings. What I need is the help of subject matter experts from many different fields to tell me what is important to them (humanitarian workers, first responders like police, fire, emt, etc, cartographers, people doing routing with OSM data, and so on). I need to know, what kinds of data are of interest to you and how much you rely on different parts of that data. I can then program that into the ontology and then use that information to make it easier for you to use the OSM data. To do this I am suggesting we all just meet on mumble as the more people we get involved in a conversation like this, the more information ends up coming out of it. The idea is to find all the little quirks in the OSM tagging system and the only way to do that is to get input from all the stakeholders. So please join mumble (instructions at the link below if you need them) and join the conversation. https://wiki.openstreetmap.org/wiki/Mumble I will be anytime during the day (US time) and I figured since today was a Sunday it might be a good day to get started. - -AndrewBuck -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTZlxzAAoJEK7RwIfxHSXbj7wP/17mO8Qipml9QfU/mauLlc5+ mQgxSp6klNtDY7nLy++YdR9WJAkd3yqmXJbKQWdqa7RcrTOQ/sf2tFOywF77NmV5 CaEBLjfXxX++MC1IMLuNRgRmvLdAS4J2Cs1mX2cRQmw3E763xPTb/1+FsmsfJHc1 nMGfNNfbNcDTJm3xSm4JrX3IA7a9SGe72qFTIA+BNGnKIPKn+Or72pk5tf77U9wN GESNgVoeWwfQyVE//KG4fx+R9R330ZbrLgUpEontOhjM3Q18rrbtkDzqKVyVfC8C KRi2ZD39+neAEVbALDI9RPp2GaiFKIL40OBRUy/nFUkb9R2Xs0RuMu59zh0fiAAP JEtlMcFpPYA67Ku7WM1LnoHZHtV3HNNMTxrA6lIFH36SfUthWoTunz88q+ASt9Fz cdn15WydJgzr7m7jF9x1lwCvEgOlmBeBZPKTFGTxrixeQza8TNUE4tfEitY2pfd+ WOdJQjyx6DFe09R+rqOfGy9y6fkdmdRNhfmo2TyJiUQDrdwsY+67D+q8V6vLlBlQ BC2tD+5Iy15jbg2bBtqkqaYxEDTVenWK2dKT9rM4uFz0jLqtRTJ1bNhpTYkf8Lw2 chgEXnP7188gaG2P/RnkVrg0nK/yaaXJEqi731+KhX9ZsGl9OdsdMVUnrfIkxw00 /zyze+8PveE8CSesdLUf =Jo5H -END PGP SIGNATURE- ___ HOT mailing list HOT@openstreetmap.org https://lists.openstreetmap.org/listinfo/hot
Re: [HOT] Looking for tagging experts or Humanitarian Workers - Help needed
Hi Andrew, This is great. I've been thinking lately that the Humanitarian Data Model needs a bit of a rework(1). Just meaning there is more information in the wiki then ends up used in most cases through projects. Building an ontology could potentially make it easier to digest. It can be hard sometimes at the moment for people to see the model and figure out how to use it.

[HOT] Tharparkar Drought in Sindh Province, Pakistan - Mapping to support Aid Deliveries
Dear All In support of the Drought Relief Efforts in The Tharparker Desert, the HOT Community has a Humanitarian Mapping Project (HMP) underway to map population areas, access roads and airfields as well as water sources and other critical information. The Tharparker region in Pakistan is the world's 18th largest desert and has been in a state of drought since late 2013. Recently more than 100 people have died as a result of the effects of the drought. The Pakistan Government has mobilized to assist this stricken area and this HMP will be useful to support relief efforts by agencies attempting to reach all the people in need. Full background information on the drought and mapping needs are on the HMP Wikihttp://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Team/Pakistan_Tharparkar_Drought Page and Tasking Manger job http://tasks.hotosm.org/job/479 exists for the area and is over 60% completed. Please help with mapping and validation so this task may be completed.
