Hi All,
I am writing a feature that will rely on geo:distance to give me the distance
between two points of latitude and longitude.
I am a total n00b to GIS and GML so I may have messed this up, but based on a
bit of research to figure out how to define the coordinate system and based on
the example query from the BaseX docs I came up with the following query as a
test:
import module namespace geo = "http://expath.org/ns/geo";;
declare namespace gml='http://www.opengis.net/gml';
let $vancouver := <gml:Point srsDimension="2"
srsName="http://www.opengis.net/def/crs/EPSG/0/4326";>
<gml:pos>49.40 -123.26</gml:pos>
</gml:Point>
let $seattle := <gml:Point srsDimension="2"
srsName="http://www.opengis.net/def/crs/EPSG/0/4326";>
<gml:pos>47.68 -122.37</gml:pos>
</gml:Point>
return geo:distance($vancouver, $seattle)
I have this in a file and am trying to execute it from the CLI with: 'RUN
[/path/to/file]'
It pukes with this error:
Stopped at [/path/to/file], 12/21:
[GEO:GEO0002] java.lang.NullPointerException
I am running off of the zip distribution of BaseX so I believe the geo module
should be included.
Any guidance would be greatly appreciated.
Best,
-Jesse_______________________________________________
