Re: [HOT] QGIS and OSM and..
Hello Phil Michael, Thanks for the quick reply, my apologies for not seeing the KML file you attached. It opens fine in Manifold but only has text comments so querying for helipad is difficult. However, just did that and got 17 possible and probable helipads from the 1444 records. How many tiles does that represent do you think? I just noticed that you indicate around 1400 potential helipad sites. However, only 17 are flagged as such and 1401 have no information in them whatsoever. None of them have any key/value attributes, how were these records actually generated? Can I assume that they are either aeroway/helipad or leisure/common? It would be nice to know which is which. Have any been validated and how is that shown? Sorry for all the questions but the pedigree for this file seems a bit sketchy. Thanks for your comments. You may be right about QGIS, I'm not that familiar with it but I know that it happily opens many of my local shapefiles with no issues. Yes, JOSM was running under remote control but the transfer of data from turbo failed with cryptic error messages. My intent, actually suggested by someone else from OSM, is to inspect existing helipad candidates, and possibly find more, using the better reconnaissance capabilities inherent in Google Earth. I think it would be important to have the tile grid boundaries for that. Anyway, this may or may not be a good idea but I thought it showed promise. I will overlay your file on Google Earth tomorrow and let you know how things look. It may not be right away as I am well behind on other things now. Thanks again to all, Cheers . . . . . . . .

In many years, I don't think I have ever seen such a complex mishmash of GIS tools. Yep, each set of tools and software have their uses, foibles and learning curve - personally I use Mapinfo, QGIS, FME, OSM, JOSM Editor, ID Editor, Google Earth, Oziexplorer, Mapsource, Basecamp and occasionally even ESRI products (even Manifold years ago!).

Hi Springfield, Alas, any import of edited data is beyond my current skill set. I am very much a beginner at HOT / OSM digitising. You will need to refer back to others in HOT for further advice before proceeding. More than happy to get the aeroway export for you. standby Cheers - Phil, On the road with his iPad On 11 May 2015, at 7:04 pm, Springfield Harrison stellar...@gmail.com wrote: Hi Phil, Right, thanks for the update. Introducing yet another data-entry method is certainly not ideal but the perspective view in GE is certainly a great help. I've edited 15 targets so far directly in GE and saved them as a different file. This file loads back into Manifold very well and, when done, I can synthesize a few extra fields of information about each helipad. Currently, I'm coding them 1, 2, 3 and adding altitude and comments. Code 1 is Good, 2 is probably OK, 3 is rejected as built-up, too small, off level, etc. I'm fairly confident with the coding so far, some ground truthng would be good. Progress is reasonably quick but there are over 1400. I now see that some of the OSM fields do not show up when the KML lands in Manifold but they are visible in GE itself. We should probably check the aeroway = helipad targets also. Really hard to assess these from purely an overhead view. I always in/zoom out, spin around and get a low level, oblique view before feeling confident. If there are tourist photos, that is also a great help. If there is any doubt about size or surface, I give it a 2. Maybe the re-integration can utilize the OSM-ID to separate the new material from the verified (relate the two tables). Perhaps some of this detail should be sorted out before I press on much further. Not sure how much time I can give this, but if it looks to be useful I will try to carry on. I've attached the edited file for your perusal. Thanks for your help, Done for now, Cheers . . . . . . . .

Re: [HOT] QGIS and OSM and..
Overpass queries offer great possibilities to extract layers of data directly
in QGIS or JOSM.
But you need to know how to write the queries. You should connect to the Live
#hot irc channel and discuss with experienced HOT contributors.
https://kiwiirc.com/client/irc.oftc.net/hot
They will provide you some examples and explain the plugins to add either to
QGIS or JOSM.

I just right now wanted to save the changes (nearly 200 buildings, now I know why one should do it earlier...) and get a message You are just to delete 466 elements, are you sure? Surely I not want to delete these ones but also I want to save my 200 buildings... Sonmeone here who knows what I did or what I can do now? Its again task 1018, #2777.

To me the unsquared buildings are not a major issue in Nepal. Within a tile a JOSM user can select buildings, then select an unsquared one remember the user select buildings once more then square all the buildings for that user in one keystroke. As a beginner I suggest you dont correct odd areas, let someone else do the dirty deed, it saves having upset users and sometimes its just a matter of someone forgetting to tag it and often an experienced mapper can glance at it and give it a tag. Paths and tracks unless its very clear I stay away from these in Nepal and Im fairly experienced. There are a number of terraces, the land can be quite steep so even though two ends of a path may look close together reality is its a long drop between the two. For the moment Id just add buildings, if you can manage to use JOSM and the building_tool plugin, youll need the remote control plugin as well youll find its very easy to use and produces squared buildings correctly tagged and we have a lot of buildings to add.

Re: [HOT] Worried about task 1018
Barbara, Sounds like you should determine what those 466 deleted elements were before saving your changeset. Which editor are you using? If you're using JOSM you can save your changes to a temporary file (File Save as) to give yourself time to sort things out. If necessary you could abandon your changes (so as not to accidentally delete 466 elements) and use the local temporary saved file to check your work as you re-do the buildings for that tile.

Re: [HOT] Worried about task 1018
Barbara, Go ahead and upload. Each rectangular buildings is 4 corners (nodes) and a connecting way. Removing one building is at least 5 elements. Worse case scenario is you upload and realise that you've made it worse and have to ask for a revert by someone. I think that the need for a revert is very unlikely. Hope this is in time.

Re: [HOT] landslides and imagery
Well I think I'm rapidly approaching the end of the window I had to work with this and figure out how to add it to osm, if anyone else wants to try, go for it. In the meantime, I just figured out how to turn it into a kml, it contains sites in addition to those mapped by British Geological Survey, Durham University, ICIMOD, NASA-JPL, Univ. of Arizona -- though one coincides: theirs: 20150508_hazard_db:FID 120 this eq_kml_shp:id -80 and eq_kml_shp:id -81.

So existing landslides can remain very dangerous for a considerable period of time. The 1 km runout, (or deposit keeping with the tagging scheme I proposed area = deposit) was not extraordinary based on volume of material, however it was extraordinary relative to most peoples' perceptions -- I doubt anyone seriously considered that a hillside that low and distant could be an active risk to an area as far away as the main highway corridor.

I'm just thinking that with aftershocks and general instability, many of these new features are still sorting themselves out and traveling downhill. Can DG or Bing make stereo pairs available? Likely a long shot, but thought I would ask. Cheers . . . . . . . .

I've mapped several dozen of these so far. In my next email, I'll cover why you won't find them in osm... yet. For this one, I'd like to stick to post quake imagery and some of its quirks. There is an inhabited hillside that had numerous landslides, some predate the quake, but most are presumably related. So far I've mapped about half of them, those that are largest or appear to threaten buildings and pathways. There is Digital Globe imagery available from May 3 and May 8. It looks like QGIS easily operates with more than one coordinate system at a time. The center of a large boulder in the May 3 imagery (Longitude, Latitude; WGS84 EPSG:3857 x,y) is at 85.85659,27.83609;9557511.789,3228324.329, in the May 8 imagery it is at 85.85669,27.83656;9557522.728,3228382.865. Mind you, this is not a complaint, rather it is a concrete example of the variability with this recent imagery.  A more extreme example is a slide that appeared to be partially blocking a stream in the May 3 imagery 85.90258,27.87818;9562631.312, 3233623.303; -- it was completely obscured by a hillside in the May 8 imagery (probably taken from a more northerly or northwesterly vantage point.)Â
Re: [HOT] Again task 1088
Hi Barbara, I know you already have your question worked out, but I thought I would just follow up on the list to hopefully catch someone's attention. The NE portion of the task square in question: http://tasks.hotosm.org/project/1018#task/2777 Really could use the hand of someone who has a lot of experience mapping dense city areas. Personally I would use JOSM tools plugin Replace Geometry feature and maybe just do some parts from scratch, not losing the any of the locally supplied data. Here is how I usually do that: https://www.youtube.com/watch?v=Kv5AOmX8M9g Again, an experienced mapper will really help out by taking on fixing this small city up so we can get that task square marked done :) Cheers, Blake On 5/11/2015 11:20 PM, Barbara Figge wrote: Oh.

Hello Phil, But it sounds as if you have heaps of experience with many GIS tools. Anyway, I will need to find out if there is any appetite for this new process to verify helipads. Not sure there is an official route for this or if I just send out more e-mails and see if anyone bites. Thanks Phil, Cheers . . . . . . . .
