Re: [HOT] Kindia Area - How to define an area with both habitat and proximity farming landuse ?
I also think that it would be important to define these activities, to find tags to describe them. I confirm that we often see these proximity farming activities around houses and it is hard to trace farming independently of housing. 2015-02-19 18:37 GMT+00:00 Pierre Béland pierz...@yahoo.fr: In rural areas of Africa, we often see areas with a mix of habitat and farming landuse. See for example https://www.openstreetmap.org/#map=16/10.40825/-12.15127 For job OSM Tasking Manager - #892 - Épidémie d'Ebola, Guinée, Préfecture de Kindia, Réseau routier et zones résidentielles http://tasks.hotosm.org/project/892, creating polygons around the houses, we often trace only part of this area, ignoring the proximity farming activity. I am opening this discussion to see if we could find a way to take into account this proximity farming. For example, we could trace a larger polygon that include both activity and use two tags two refer to this landuse. 1. landuse=residential 2. ???=proximity_farming? Any comment, propositions?

Re: [HOT] Canaan Haiti Mapping
Thanks for updating the links Emir and Blake. I'm still not used to the link structure of the new Task Manager. The sky was very very blue during our time mapping. In the next few weeks additional roads and paths will be completed and uploaded for Mapillary. We plan to revisit, using mapillary, a large portion of Canaan every three months or so and continue to improve the map.

[HOT] leisure=common (Helipad)
Project 892 task 23 is an example. The following question got sent to me probably because I've been validating merrily away. What is the minimum diameter for a Helipad (leisure=common)? Based on my own experience of visiting a remote Scottish Island the local football pitch, being smooth, level and firm enough was the designated helicopter landing place. I'm not sure that you can tell enough from satellite imagery that a certain bit of ground is smooth, level and firm enough to take the weight of a helicopter. However we seem to have a fair number of circular leisure=common areas tagged near fairly small villages. So can we flesh out a bit more of the requirements please and better identify what we should be looking for and mapping.

Re: [HOT] leisure=common (Helipad)
Hi John, It is actually a quite difficult thing to specify because the performance of helicopters varies dramatically. To explain .. Temperature and altitude play a very large role, basically the higer you are, the thinner the air, the less bite on the rotors. There is a measure called density altitude, which is where the temperature comes in, the hotter it is, the thinner the air = same issue as above The combination of the two is one of the most important things a pilot looks at There are very few helicopters that routinely take off vertically, generally they will rise to a hover then move forward in ground effect (which is like a cushion of air between the rotors and the ground). This actually allows heavier helicopters to take off without needing so much power for a vertical climb out, and which many cannot do for performance reasons and options if they have an engine failure. Weight is another very critical factor, but that is an operational matter we will never know anything about and is often driven by temperature and altitude issues as well. So the bottom line is not so much the actual space, it is the approach and departure paths that are the most critical. Some choppers can come right in and drop and depart vertically, say into a foot ball field surrounded by a stadium. However, I know the pilots would much prefer to have options for approach and departure that gives them a way in and out without having to climb vertically, and probably means that they can carry more in terms of payload, people, etc. Again, this is all very much dependent on the type of helicopter, some can do it, others not depending on their performance envelopes. If we map the buildings around any marked landing areas, then any pilot will know immediately he is dealing with obstacles and can plan his flight accordingly. Height of those building is a VERY useful piece of information, but one we are unlikely to be able to provide from Sat images The other thing we can do is map power lines, other buildings, and groups of trees around the LZ's to show possible approach and departure paths, this would be very useful information for mission planners and pilots Hope that helps Regards Mark Cupitt If we change the world, let it bear the mark of our intelligence See me on Open StreetMap https://www.openstreetmap.org/user/Mark_Cupitt On Thu, Feb 19, 2015 at 7:31 PM, john whelan jwhelan0...@gmail.com wrote: Project 892 task 23 is an example.

Re: [HOT] leisure=common (Helipad)
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 As Pierre has noted we map what is on the ground, not what how we think it should be mapped. If there is a common area then we tag it as such, if there is not then we should not 'invent' one that is close by simply for the purpose of having one. It is important to note, the reason I asked to have these mapped is that they _might_ be used as helipads, not that they must be. As Mark noted, the criteria for what is an acceptable landing site is something only a pilot can decide, and even then only for a specific helicopter and specific load. All we can do is tell them reasonable places to start looking, but it is for them to decide if any of the areas we marked are acceptable. I expect that they would try to review the area in imagery anyway or have someone confirm it on the ground before dispatching a helicopter there. Our data is not the final word, just something so that they have a starting place. As to the round areas, I have noticed several mappers doing this. Not sure if it is a newbie thing or what, but the area should not be mapped as round unless it is actually round. Otherwise we should be mapping the proper shape. - -AndrewBuck On 02/19/2015 08:16 AM, john whelan wrote: So the advice back to the mapper?

Re: [HOT] What is a hot activation?
Hi There was some work a while back to put more definition around the stages of Activation, and differentiate from HOT related activities or projects. http://wiki.openstreetmap.org/wiki/HOT_activation. There's lots done in the HOT community which doesn't go through the activation process, including the original Gaza effort back in 2009, which led to the formalizing of HOT. At the Board face to face in June, we made a priority to define a HOT project, broadly encompassing all kinds of activities taking place in the HOT community, even if not an official project or activation. In any case, I think there's more work to be done to make this clear and useful for us. I think the Activators Training and HOT Summit will be a great time to work on these. -Mikel * Mikel Maron * +14152835207 @mikel s:mikelmaron On Thursday, February 19, 2015 12:18 PM, Blake Girardot bgirar...@gmail.com wrote: Hi Fred, My responses are in line below.

Re: [HOT] What is a hot activation?
Accidentally only replied to Fred. Resending with everyone copied in. As someone that uses HOT resources a variety of ways for American Red Cross and Missing Maps I have a few opinions on your questions. First I really love the work done by you and others in Gaza as it really showed the growth of HOT and a reflection of lesson's learned from theHaiyan OSM Assessment http://americanredcross.github.io/OSM-Assessment. … *When we know that is an Hot activiation. For gaza it wasn’t an HOT activation, as we didn’t decide it.* Anytime you use the HOT Tasking Manager to organize volunteers and work the project becomes a HOT project. Even if in the situation of Gaza or any number of ARC or MSF or Missing Maps projects the requesting NGO supplies the majority of the volunteers through mapathons or social media calls the volunteers themselves are still HOT volunteers. In my opinion activations are different in that they have a HOT lead, typically an activation lead, shepherding the process as is the case for Ebola or Malawi floods or similar type disasters. The idea that HOT 'activates' is still one of the weirdest things about HOT. HOT has truly only 'activated' a few times over the past five years. The vast majority of the work, from my perspective, is similar to Gaza or the DRC or Dhaka. … *It was just an initiative as an OSM and HOT members done in a short period of time.* Whether the effort was short or long doesn't change the fact that the Gaza effort used the Tasking Manager to marshall volunteers and organize the work. … *Who can use this tasking manager : NGO, state, local OSM group, etc* The TM has policies in place for establishing new tasks and folks capable of creating tasks. I think the current system works pretty well of having seasoned HOT folks guide and mentor newer TM folks like myself until we gain enough experience to create our own tasks. … *Of course a real HOT activation can improve the communication/mobilization. , but according to the news at that time we just digitized as fast as we could. * I've learned a very important lesson during my time at ARC; communication about what you are doing and how you are doing it is almost as important as the work. Communicating and bragging like Mikel was doing about the Gaza mapping opens more doors, forms new partnerships, and validates the work that so many of us do. I suggest that when projects are complete that the creator of the project should share the outcomes and their experience with the project/activation through blog post on hotosm.org much like Pierre and Andrew do for activations. This allows the community to be informed and be aware of others activities. … *So how many big activation could we handle at the same time?* Great question. As HOT has gotten better at its work and NGOs adopt it more into our business process and workflows the frequency and expectations we put on HOT are only going to grow. It is really important that HOT grow with those expectations. This is one of the reasons you saw many organizations come together to improve the tasking manager. Its also a reason MSF and the Red Cross founded Missing Maps. It allows us to give back and strengthen HOT as a true partner.
