Re: [Geotools-gt2-users] Failed to execute request to WMTS

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>

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"; xlink:role="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"; xlink:role="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. Geotools is tolerant elsewhere, so it could certainly be a place for a little flexibility. Not sure how to handle it though. 

Best regards,

Height is in pixels and is an integer value so your value of 85.5 is a problem, your code example doesn't show how you are generating the size request but I would expect a height/width of 255 or 512 for a WMTS request. It's possible that the GeoTools WMTS code doesn't understand the TIME dimension or the value RESTful as an encoding, you'll need to turn the logging level up to find out exactly why that URL is being used.

    Hello GeoTools community,
    I'm new to GeoTools. Currently I'm trying to establish a
    connection to a WMTS. I followed the instructions in the WMTS —
    GeoTools 28-SNAPSHOT User Guide
    
<https://docs.geotools.org/stable/userguide/extension/wmts/index.html#wmtstileservice>.
    Unfortunately the request to the WMTS failes.
    *Here are my system information:*
    GeoTools version 28-SNAPSHOT (built from
    r175672287370cf2c54eb30f2bbaa04f743835523)
    Java version: 17.0.4.1
    Operating system: Windows 10 10.0
    GeoTools jars on classpath:
    I use Maven. My pom.xml is pretty much the one from the
    quickstart tutorial but of course I added the gt-wmts dependency.
    *Here is my error message:*

            URL url = null;

            } catch (ServiceException e) {
              // The server returned a ServiceException (unusual in
    this case)
            } catch (SAXException e) {
              // Unable to parse the response from the server
              // For example, the capabilities it returned was not valid
            }

     System.out.println(wmts.getCapabilities().getService().getName());
        }
    }

    I tried different servers. I get a response to a manual request
    from all of them.
    It would be very much appreciated if anyone has a solution or a
    hint for me.
    Thanks in advance,
    Daniel
