Hello Michael,<br><br>
<x-tab> </x-tab>Further
investigation using shapefiles that I believe were derived from the Hot
Export system, I inspected these in my own GIS, Manifold GIS:
<ul>
<li>"planet_OSM line, point, roads" shapefiles contain
key/value attributes but do not project at all; projection information
from the PRJ file copied below. It appears to be a custom
projection that I would have to hardwire into Manifold.
<li>"latest" shapefiles projected and displayed correctly but
appeared to have just basic civil map information, nothing OSM related it
would appear
</ul><x-tab> </x-tab>So,
sorry to report that nothing useful has come from all this OSM data
download thrashing. I'm willing to press on if someone has a
guaranteed recipe, but my energy and enthusiasm for further
experimentation is pretty well finished. OSM data dissemination is
significantly inhibited by a plethora of file types and poorly connected
tools, in my opinion. After two or three very late nights I have 0
bytes of useful information.<br><br>
<x-tab> </x-tab>This is
unfortunate because there is huge potential in extending the utility of
all this laboriously generated information. I was especially
looking forward to reviewing and possibly improving upon the helipad
information. As Pierre has noted, with so many displaced survivors
living in very difficult circumstances, and with the monsoon approaching,
reliable helicopter access will probably become even more
important. In bad weather in the mountains, roaming around in a
helicopter to find a landing spot is not fun and one's first inclination
is to stay in the tent. However, if helipad destinations are
accurately mapped, pilots will be more willing to try a trip in dodgy
weather if they have a good idea of where they are going.<br><br>

</x-tab>Thanks again for
your help and patience, Cheers . . . . . . . . Spring Harrison<br><br>

I am afraid but this is standard behavior in any editor. Basically this
is not the way to go if you actually want to download OSM data for
consumption.<br><br>

Is it not possible to simply get a shapefile<br>

If you actually want a shapefile for all of Nepal I would recommend using
one of the available downloads listed on
<a href="https://wiki.openstreetmap.org/wiki/2015_Nepal_earthquake#Exporting_OpenStreetMap_data" eudora="autourl">
https://wiki.openstreetmap.org/wiki/2015_Nepal_earthquake#Exporting_OpenStreetMap_data</a>
<br><br>
But if you are only interested in some feature you should have a look at
Overpass Turbo. This allows to download filtered results.
<a href="http://overpass-turbo.eu/s/9hb" eudora="autourl">
http://overpass-turbo.eu/s/9hb</a> is a sample query for aeroway=helipad
in the area showed in the map. But unfortunately this will not yield
shapefiles. Also the query language requires to go through some learning
curve if you want to create a bit more complex queries.<br><br>
