Hi, I've looked more into how to handle this irregular capabilities document within GeoTools, and found a solution that works without contacting NASA. It isn't the prettiest thing, but it works. The main point is to make a custom WMTSConfiguration that overrides the binding for positiveInteger.
I've made a gist of the solution, if anyone is interested. https://gist.github.com/roarbra/c676cdc933fe2c4880c9e17995e9516d <https://gist.github.com/roarbra/c676cdc933fe2c4880c9e17995e9516d> Best regards, Roar Brænden > 2. des. 2022 kl. 16:09 skrev Matthijs Laan via GeoTools-GT2-Users > <geotools-gt2-users@lists.sourceforge.net>: > > Looking further into this specific service, apparently this WMTS capabilities > document is generated by a Lua script that just copies the width and height > values from a YAML configuration file, without making sure the resulting > capabilities valid according to the WMTS schema. > > The Lua code is here: > https://github.com/nasa-gibs/onearth/blob/main/src/modules/gc_service/gc_service.lua#L514 > > <https://github.com/nasa-gibs/onearth/blob/main/src/modules/gc_service/gc_service.lua#L514> > > An example YAML file with a 85.5 height for a legend is here, among other > places: > https://github.com/nasa-gibs/onearth/blob/main/docker/sample_configs/layers/epsg4326/best/GEDI_ISS_L3_Elevation_Mean_Lowest_Mode_201904-202004.yaml#L43 > > <https://github.com/nasa-gibs/onearth/blob/main/docker/sample_configs/layers/epsg4326/best/GEDI_ISS_L3_Elevation_Mean_Lowest_Mode_201904-202004.yaml#L43> > > Maybe you can send an e-mail to supp...@earthdata.nasa.gov > <mailto:supp...@earthdata.nasa.gov> to ask them to change their YAML files to > use integer legend widths and heights or create an issue in their GitHub > repository. > > Matthijs > > On 02/12/2022 11.15, Matthijs Laan via GeoTools-GT2-Users wrote: >> XML Schema says Capabilities are invalid. >> >> <attribute name="width" type="positiveInteger"> >> <annotation> >> <documentation>Width (in pixels) of the legend >> image</documentation> >> </annotation> >> </attribute> >> <attribute name="height" type="positiveInteger"> >> <annotation> >> <documentation>Height (in pixels) of the legend >> image</documentation> >> </annotation> >> </attribute> >> >> Matthijs >> >> On 30/11/2022 15.55, Roar Brænden wrote: >>> Hi, >>> >>> It seems like this height=85.5 is coming from the capabilities document. >>> Here for instance: >>> >>> <Style isDefault="true"> >>> <ows:Title xml:lang="en">default</ows:Title> >>> <ows:Identifier>default</ows:Identifier> >>> <LegendURL width="378" >>> xlink:href="https://gibs.earthdata.nasa.gov/legends/AMSU_Brightness_Temp_H.svg >>> <https://gibs.earthdata.nasa.gov/legends/AMSU_Brightness_Temp_H.svg>" >>> xlink:role="http://earthdata.nasa.gov/gibs/legend-type/horizontal >>> <http://earthdata.nasa.gov/gibs/legend-type/horizontal>" height="85.5" >>> format="image/svg+xml" xlink:title="GIBS Color Map Legend: Horizontal" >>> xlink:type="simple"/> >>> <LegendURL width="135" >>> xlink:href="https://gibs.earthdata.nasa.gov/legends/AMSU_Brightness_Temp_V.svg >>> <https://gibs.earthdata.nasa.gov/legends/AMSU_Brightness_Temp_V.svg>" >>> xlink:role="http://earthdata.nasa.gov/gibs/legend-type/vertical >>> <http://earthdata.nasa.gov/gibs/legend-type/vertical>" height="288" >>> format="image/svg+xml" xlink:title="GIBS Color Map Legend: Vertical" >>> xlink:type="simple"/> >>> </Style> >>> >>> Haven't looked in the WMTS specification to see if that is against the >>> rules, but sure isn't anything the user could fix.
