I have imported my georeferenced jpg which I believe (on the basis of metadata in xmml file) to be in the NZGD2000 TM coordinate system.
Origin: 1.76759e+06,5.94938e+06 Pixel Size: 1.08167,-1.08182 No Data Value -32768 Data Type: GDT_Byte - Eight bit unsigned integer Pyramid overviews: Layer Spatial Reference System: +proj=tmerc +lat_0=0 +lon_0=173 +k=0.9996 +x_0=1600000 +y_0=10000000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs Layer Extent (layer original source projection): 1767594.1269140779040754,5946587.8368053492158651 : 1770700.6877073212526739,5949380.0231113545596600
the waypoint data layer from the GPS metadata:
General: Storage type of this layer: GPS eXchange file Source for this layer: /Volumes/GARMIN/Garmin/GPX/Waypoints_19-JAN-13.gpx?type=waypoint Geometry type of the features in this layer: Point The number of features in this layer: 8 Editing capabilities of this layer: Add Features, Delete Features, Change Attribute Values Extents: In layer spatial reference system units : xMin,yMin 174.891,-36.6086 : xMax,yMax 174.893,-36.6074 Layer Spatial Reference System: +proj=longlat +datum=WGS84 +no_defs
Clearly I need to convert the the GPS data to NZGD...
I first tried changing the coordinate system on GPS -- this displays the data on the GPS in correct coordinates but does not affect the exported data.
The import from GPS does not appear to allow one the specify any conversion.
I also tried changing the CRS of the layer but this does not appear to convert data just changes the interpretation of the existing coordinates.
Clearly I am missing something basic.
BTW using garmin's basecamp I was able to plot these points on google earth without problems so I know this is possible :)
