Re: [HOT] Vanuata Islands, Pam Cyclone
We have a wiki page for Vanuatu so I've added details to that and links to the TM projects on there http://wiki.openstreetmap.org/wiki/Vanuatu For your second TM project, Pierre, I've tweaked the description to say that Bing is only available at hi-res on the northernmost squares.(Bing coverage map: http://ant.dev.openstreetmap.org/bingimageanalyzer/?lat=-15.587324766473579lon=168.431396484375zoom=9l=bing ) We can spot any roads and settlements but in most squares there's none of this. There is a fair bit of work we could do in Vanuatu on coastline refinements (lots of coarse PGS data) adding of missing natural=beach areas, and rivers. Not very important data, but it aids navigation. To decrease the chance of edit conflicts on coastlines I've split some of them into smaller ways. Could do more of this. When doing this with a fresh island, they are often in as a single way which also carries a place=island and name tag. That needs converting to a multipolygon.

Yes Rafael quite sad. With these unconnected villages, it is important to locate them and identify helicopter landing space. But with dense forests, it is hard sometimes to spot houses.

And before giving the relay to others Thanks all for this fantastic response In less then 8 hours, 80% of TM job 943 is completed and 25% of TM job 944.http://tasks.hotosm.org/project/943http://tasks.hotosm.org/project/944 We still have fragmented infos from Vanuata. For this Class 5 cyclone (highest level), as powerful as the Haiyan Typhoon in Philippines, winds over 330 km/h and waves over 7 meters high have been reported (France Tv). From Vanuatu, Australian Red Cross workers have tweeted unbelievable destruction. Whole villages have been flattened. Baldwin Lonsdale, the president of Vanuatu, assisting at the Sendai, Japan conference, appealed to the international community to support the Vanuatu population in response to such a calaminity. This 800 km long archipel have a population of 270,000 persons spread in a multitude of islands. A first report from UNICEF reports 44 deaths in the Penama province (33,000 people). Going further south, the cyclone passed closer to Port Vila then was expected. More then 2,000 people took refuge in shelters. Note that with the communication cuts, it can take days before we have an exact picture of this disaster. more infoshttp://www.stuff.co.nz/world/south-pacific/67366444/Cyclone-Pam-hits-Vanuatu-Death-tally-begins Pierre ___ HOT mailing list HOT@openstreetmap.org https://lists.openstreetmap.org/listinfo/hot

I've noticed some variation between the mappers when validating. Could we also have a guideline on huts? I've seen them mapped as a single point and as a circle. In JOSM its very quick to copy and paste a hut but that does mean slight variations in size are not mapped correctly. The other issue would be isolated buildings, I tend to map the building rather than tag it landuse=residential again a guideline would be useful.

Re: [HOT] West African HOT Mapping Tips
Hi John, We have talked about making them more widely available and we do include them in some of the W. Africa instructions or pass them out to mappers individually, sometimes as part of validation feedback. I have a short list of revisions is partly why I have not moved them out from my personal page yet in the wiki and called them done As to the huts: It can go either way, but it is my understanding we usually try and map the building footprints as it provides just a little bit more data, approximate size and can help when working physically on ground for orienting yourself a little better than just a point on a map. But it is up to the project manager to determine what data they need v. how fast it can be generated. In one circumstance just getting a building count and structures represented on the map quickly could be a lot more important than whatever else we gain by an actual building footprint. And sometimes the circumstances of mapping affecting things. If you are working in the field on a smart phone collecting building locations off line and entering data for each building, outlines would be impossible. As to drawing the huts quickly, you might already know these things in JOSM, but just in case: When you copy/paste, where you hold the cursor will be the center of the pasted object. So hold your mouse pointer directly in the center of the hut to paste. Then with the newly pasted building selected, hold control-alt keys down and you can resize the object you just pasted based on the center of the pasted object. That lets you quickly get the pasted hut the correct size.

Re: [HOT] West African HOT Mapping Tips
Hi Severin, I can share all the originals ( I think/hope I still have them ). That was my main mistake, the text on the images making the translation difficult. It was a process and you can see in later items the text came out of the images and went into the caption to make translation easier. That is also the style Nick has implemented in LearnOSM: Numbered arrows for detail and clarity in the illustration, and then text explaining the details of the illustration and they look great. As to the videos: I also have a few of those, not silent unfortunately :) But I have recently thought about doing short animated gif illustrations and passed around the Training WG email list a few tools that do that well. Here is an example of tutorial with animated gifs that used something like the tools I passed around to the Training WG. This example is busy ... maybe a bit too crowded for all the activity on the page, but gives a good idea of what someone can do with short animations for tutorials. Laid out better like Mikel's example of Bangladesh mapping and it could be very educational and low bandwidth. https://www.mapbox.com/blog/mapillary-mapping/ Cheers, Blake On 3/14/2015 2:05 PM, Severin Menard wrote: Hi Blake, This is a great tuto, would it be possible to share the original pics for translations?

Re: [HOT] open geology map
Sander, I agree with most of your points and would like to add that surface geology is a highly specialized field requiring a great deal of expertise. I'm a geology buff myself, and there is no way I would attempt to map that. Also, there often is strong disagreement among geology professionals about the nature and dating of rock units, disagreements that make some of our set-tos about how to code sound trivial. Also, there generally is a lot of local information about landslides and tsunami risk, courtesy of the USGS, though sometimes it is ignored. In Los Angeles, tsunami-prone areas are signed along major roads, as are the areas subject to debris flows. The recent deadly landslide in Oregon was in an area known to experience landslides, but apparently the risk was not widely publicized. Tsunami risk, perhaps, could work as an overlay, and I believe that data is available from the USGS.

As such, OSM contains no height or slope data (apart from the elevation of some peaks), but leaves this to professionals (such as the NASA). It isn't so hard to extract a general slope from good precision elevation data, so there's no point in including it directly in OSM data (with the right preprocessor, it can get rendered on the map anyway).

But sadly, there's no crowd around there, so the most we would be able to do is some mapping from aerial pictures. This shouldn't hinder you from starting the project, but you shouldn't have very high expectations from it.

You describe them (anything from field IDs like greenish rock #2 to detailed technical descriptions) and give them proper names (e.g. the Tunbridge Wells Sand Formation). Having mapped the boundaries between different rock types, you can also trace faults and the line of folds in the rocks. These all obviously exist in 3-D, but are usually represented on 2-D maps. Just mapping the 2-D trace is enough for many purposes. OPTIONAL EXTRA 3-D
Re: [HOT] Vanuata Islands, Pam Cyclone
This is a category 5 Cyclone, the highest category and many deaths reported. ReliefWeb map, March 13, shows that the Islands south of Port Vila should have been the more affected. http://www.static.reliefweb.int/map/vanuatu/vanuatu-tropical-cyclone-pam-13-march-2015 I see two islands of about 30 km x 30 km and smaller islands.

Re: [HOT] open geology map
So probably the best place for it would be a separate database that could be combined with OSM data. There is no reason why it couldn't use OSM format and tools such as JOSM though. I worked in a library for a while and we had a theory that if you asked five classifiers how to classify a book you'd get six different answers.

I'm a geology buff myself, and there is no way I would attempt to map that. Also, there often is strong disagreement among geology professionals about the nature and dating of rock units, disagreements that make some of our set-tos about how to code sound trivial. Also, there generally is a lot of local information about landslides and tsunami risk, courtesy of the USGS, though sometimes it is ignored. In Los Angeles, tsunami-prone areas are signed along major roads, as are the areas subject to debris flows.

Re: [HOT] Vanuata Islands, Pam Cyclone
The communications are cut with the Vunuatu Archipel. From the information I gathered, I prepared a task wihth the islands that seems more severely hit. I invite you to map these rapidly as Red Cross and other prepare to deploy. We will creat other tasks if necessary when more information is available. We want to mark roads, residential areas, possible shelters, helicopter landing, communication towers.
