Greetings,

Is there an easy way to use this data in QGIS (with terrain profile plugin) with access via api?


I have it kinda working after downloading the geotiff file for a particular area and then loading each tiff tile as a separate layer.

It would be nicer if it could work the same way as imagery layer uses WMTS layer.

Hi Eliot,

I'm not seeing that layer available in the LINZ data service WMS layer-list.

I'd suggest to download the GeoTIFFs you need then link them together
into a single virtual
raster using GDAL's "gdalbuildvrt" tool (it's awesome), then generate
your profile from that
combined virtual-map.

Alternatively you might try downloading SRTM (~90m res) tiles or Otago
School of Surveying's
national DEM GeoTIFF tiles from Koordinates (~15m res), as maybe you
can do all you need
to within a single GeoTIFF tile in those cases.

(or maybe someone else besides LINZ has already set up a WMS server
containing one these?
there'll be an international WMS server which provides all the SRTM
tiles somewhere out there
on the 'net for sure)


regards,
Hamish
