support dimension (time) for WMTS 1.0.0

[murdav]

Dear All,

Following http://portal.opengeospatial.org/files/?artifact_id=35326 there is the possibility to have the dimension, page 22 Table 9 — Parts of Dimension data structure.

e.g.

<Style isDefault="true">
  <ows:Title xml:lang="en">default</ows:Title>
  <ows:Identifier>default</ows:Identifier>
</Style>
<Format>image/png</Format>
<Dimension>
  <ows:Identifier>time</ows:Identifier>
  <ows:UOM>ISO8601</ows:UOM>
  <Default>2017-05-16</Default>
  <Current>false</Current>
  <Value>2015-07-30/2017-05-16/P1D</Value>
</Dimension>

A getcapabilities example could be:

https://gibs-b.earthdata.nasa.gov/wmts/epsg4326/best/wmts.cgi?Service=WMTS&Request=getcapabilities&Version=1.0.0

If there is no program to support it, I can have a look at it.

@tomkralidis the issue is that the WMS-T has a different structure (page 53, 06-042_OpenGIS_Web_Map_Service_WMS_Implementation_Specification.pdf), could you give me a bit of help, maybe some points of start?

Thanks,

D

@murdav looking at http://schemas.opengis.net/wmts/1.0/wmtsGetCapabilities_response.xsd, wmts:Dimension occurs 0..n times in a given Layer element.

I would create a dimensions property which is a list of each dimension with the appropriate properties, starting at around https://github.com/geopython/OWSLib/blob/master/owslib/wmts.py#L773. The wmts:Value property being a list of values.

Thanks for this!
Further question, I didn't find how I can run OWSLib tests before pulling the request from my fork to master. I got some minor errors (like field title has changed the value) that I can easily update.
Is it possible to run the tests locally, if so, how?

@murdav you can run the tests with py.test (see how Travis does it in https://github.com/geopython/OWSLib/blob/master/.travis.yml#L17). Note you can also run tests on single doctest files.

+1 for this feature request!

Feature is implemented in #904 and for now can be used from a fork https://github.com/lubojr/OWSLib/tree/368-wmts-dimensions-support if anyone needs it before this gets merged to master.

Thanks @lubojr. Merged.
