Hello Michael,<br><br>
Thanks for your reply.<br><br>
<font face="Arial, Helvetica">So you are confirming that downloading OSM
data through JSOM is a waste of time? I wish I had known this
earlier. I was advised that it would download all of Nepal but that
doesn't seem to be the case.<br><br>
I tried the open street map data link that you provided. It shows
some promise but I haven't looked at the data yet. [Just looked at
some of those shapefiles, they do load and display in QGIS.
However, when I tried to change the symbology for the helipads, they all
disappeared. WTF?]<br><br>
I also stumbled upon the HOT Export site. It is very convoluted but
also shows promise once one figures out the myriad of options.
Creating presets would be helped enormously if there were drop-down lists
for the keys and their values. My last attempt here failed,
probably due to bad capitalization or some such. It looks like a
dog's breakfast.<br><br>
Now I see your reference to Overpass Turbo, hopefully not another blind
alley. Simply downloading data in OSM is anything but
streamlined. The key/value concept seems to complicate things
considerably. What is the benefit of that system?<br><br>
I have fired up Overpass Turbo. Used the wizard to create and run a
query but the export options only offers some less than useful
choices. GPX and KML files are of limited use in a GIS and I don't
recognize any of the other files. The geojson file was only
recognized by QGIS but it would not display.<br><br>
Then I tried the KML and GPX files. I'm QGIS the KML file was
listed but not accepted for viewing; the GPX layers were accepted but
would not display. In JSON the KML file was not recognized and GPX
file would not display.<br><br>
If I recall correctly, the option to send the query results directly to
JSON failed also.<br><br>
This is a huge amount of trial and error with very little, almost
nothing, to show for two late nights. I appreciate everyone's
attempt to help, and have read many wiki pages but she's all
uphill.<br><br>
My intention is very simple -<br>

<font face="Arial, Helvetica">download a shapefile of the Nepal task
tiles<br>

<dd><font face="Symbol">·<x-tab>

<font face="Arial, Helvetica">download a shapefile of the potential and
actual helipads [this might have been achieved with the Hot Export, the
many attempts are all blurring together now]<br>
</font>
<dd><font face="Symbol">·<x-tab>
</x-tab></font>
<font face="Arial, Helvetica">possibly download a shapefile of other
features<br><br>
</dl>If someone can outline a GUARANTEED process to achieve that I would
be most appreciative. In most GIS environments, these are everyday
activities accomplished with a few mouse clicks. In many years, I
don't think I have ever seen such a complex mishmash of GIS
tools.<br><br>
<x-tab> </x-tab>Thanks
very much, 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>

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>
