AGENDA copy:

2). Actions points from last meeting (some on main agenda):

9th OneGeology (Global) Technical Working Group Meeting 5th June 2013 2.30-5.30pm at A. P.Karpinsky Russian Geological Research Institute (FGUP "VSEGEI") 74, Sredny prospect, 199106, St. Petersburg, Russia, VSEGEI

AP1: It was confirmed that the Israeli survey has not been heard from regarding 1g since 2007. The secretariat will attempt to re-engage with this survey and others following the OneGeology Consortium stakeholders meeting in October 2013

by end of July approximately 50 GSO will be written to to request rejoining.. Focus in on organizations that can not afford to join as Principal members. See 'Governance' page on OneGeology.org.

AP2: BGS/BRGM/AZGS to finish GeoSciML _Portrayal cookbook and make the SLD query portrayal tool live in the production OneGeology client.

AP3: BGS to contact Belgium and get that service upgraded and to make the WMS cookbook explicitly point out this issue when recommending the half dozen projections to be declared by a WMS and so to work with this tool.
  • Note 1, by Belgium above it means Royal Museum for Central Africa (who host Rwanda-Burundi and DR Congo).
  • Note 2, the issue surrounds the fact that their GeoServer based service was declaring multiple SRS (the default for GeoServer) and it was thought that this was simply because they were using an older version of GeoServer (which they weren't).
James reports that problem is solved. Issue had to do with offered CRS. Issues were created by GetCapabilities documents listing thousands of offered CRS. Belgium service is now reporting only 6 CRS.

AP4: BGS to provide Francois with suitable datasets for him to create area specific backdrops wms’ for the problematic Arctic and Antarctic areas and BRGM to implement the multi-projection functionality such that it would be improved to analyse the declared SRS’ in the service level GetCapabilities list and if a non-declared projection was requested of a layer then that layer would be greyed out or similar (as is done with other such limitations in the portal) and the raw error message would therefore not be generated.

AP5: China Geological survey to publish OneGeology 1:1 Million WMS by summer 2014.

Tim reports that the PRC Geological Survey has deployed WMS for China at 1:1,000,000. Deploying in English and Chinese.

AP6: SEAMIC to progress discussions with Sudan and Angola.

Southeastern Africa Minerals Research Institute is buddying for multiple countries. E-mail this morning looks likely that the South African Geo Survey will become principal member and represent Africa for the board.

AP7: BRGM to implement the agreed GeoSciML 3.2 age and lithology queries with the existing statistics tool. BGS to provide exemplar test services for this.

on today' agenda.

3). Demonstration and review of GeoSciML -portrayal SLD query tool in the portal.

At 9:30. James Passmore takes screen to demo the SLD Query tool.

BRGM formally agree on September portal release that will reduce JavaScript loading of open layers. Should improve performance, and address problems with time out on loading.

Worked with US/Delaware service showing recoloring by CGI SimpleLithology Term. Tim reports the tool is working well. Still debugging why doesn't work with most of the ArcGIS services. may be related to post 10.0 ArcGIS server.

Christy Caudill reports 9 US state services + USA service are GeoSciML portrayal conformant and registered. 14 additional services are deployed from other states but not registered. People seem to be intimitdated by registration process.

Christy also prepared Checklist for registering; some items are USGIN specific. Tim proposed that this could be adopted (with adjustments) for use by OneGeology in general, and added as annex in cookbook. James pointed out that we need to rewrite cookbook. It has been accreting stuff at the end and is in danger of becoming incoherent. Christy suggested linking to the check list as a resource that people might find helpful. James agreed, pointed out that merging the two documents would be time consuming. Tim summarized--documentation is accurate, and many more services are almost to be deployed

Action ITEM. Christy to send James and Tim a copy of the checklist document for consideration on how to integrate with other documentation.

Ollie asked if anyone has solved the problem with ArcGIS server not allowing configuration of WFS response schema locations.

James reviewed Documentation for WMS profile currently accessible from OneGeology.org. Add some extra sections in WMS cookbook, Chapter 7 on GeoSciML -Portrayal WMS. Provides links to CGI age and Lithology dictionaries. Appendix K and L are about deploying GeoSciML portrayal with GeoServer and ArcGIS server.

ASIDE: have received from Sweden GeoServer WMS, WFS. Uses the OneGeology Europe connector, GeoSciML 2.1. Tomas Lindberg reported to Tim. James will register soon.

Review of documentation – ok to promote widely now? Relationship with USGIN cross-tile desired query. Refinements still needed in USGIN/AZGS hosted services to work with this tool? (only Delaware working today despite the fact tool now allows either ArcGIS or GeoServer /MapServer WMS’ to work). Discussion of imminent widening of potential services that will work with this tool e.g. South America?

4). Discussion of GeoSciML 3.2 query tool,

review including documentation – ready for wide promotion? When will the GeoSciML xml download option be added?

10:12 am

Marcus Sen demonstrate Query tool, against full GeoSciML v3.2 WFS. Full Statistics and Lithology Statistics buttons are enabled in the layer details window. Can select a particular lithology. Need to zoom in so have a relatively small number of polygons. Will allow lithology constraint AND age constraint based on CGI simpleLithology and ICS geologic time scale URIs. Query errored in demo; Marcus had to debug.

combines lithology with proportion; selects polys of unit with >= that proportion.

Cookbook 4 on OneGeology.org download pages describes how to set up service for GeoSciML3.2 that will work with this tool.

Have cookbook for 5 star service with Geoserver as well.

Action item: Francois will add button at bottom of statistics page to download the GeoSciML. GeoSciML include polygons that intersect the view frame.

Carlo pointed out that the lithology hierarchy can be difficult to navigate for some users. It would be a good feature to be able to search Lithology tree. Francois said it could be done, but will not be by septemberl

Discussion of the INSPIRE dictionary requirements in these WMS/WFS queries, the future joint publication of the exactmatch INSPIRE/CGI uri’s by the INSPIRE registry and the real funded possibility of a GeoSciML to INSPIRE schema ‘transformation tool’.

Discussion of performance requirements for GeoServer (for ERML?) and work from 1st July by CSIRO-Prth on such performance improvements.

CSIRO is starting today on improving performance. ERML 2.0 model testing; Francois has done some testing, reported results this A.M. GeoServer 2.5.1 version create ERML v2, and performance is OK with 100 features, is faster than before. CSIRO work is under auspices of AUSCOPE. JSON support, WFS paging with appSchema. Tim will discuss with Ben Caradoc - Davies, how to get GeoServer made into WFS v2.0 reference implementation. Deegree is currently the only WFS2.0 reference implemenation.

Sylvain noted that it is unfortunate that only Ben C-D is supporting the AppSchema extensions in GeoServer; need a more robut developer base. Time clarify: Ben C-D is only GeoServer Board Member promoting appSchema (others are in simple feature arena).

NOTED: It is in the interest of OneGeology, INSPIRE and Auscope that GeoServer board apply for OGC Reference implementation status for GeoServer /WFS2.0.

Action: Francois will continue to test performance with full database, and post issue to GeoServer if it is still not acceptable.

Minerals4U (European minerals data services) will be using Deegree for services. EuroGeosurveys project is already using Deegree for borehole data, was easier to continue using. Tim suggested to james P. that it would be good to revisit Deegree w.r.t. OGC services for BGS.

4a) Metadata:

Leah. Trying to integrate OG metdata harvest into USGIN catalog.

GetCapabilities does not have Title

~ 3/4 of records don't validate, can't harvest. 120 newer records do validate.

Elements in wrong order (metdataStandardName, version, DateTime); EX_Extent, elements in wrong order (northboundinglatitute...). Eric B. noted that the getRecordsREsponsse is using gml 3.1 namespace, so it must be a custom XML output.

Pascal and Agnes have been doing the metadata, Francois, Sylvain haven't been doing.

Ollie mentioned CGI is going to sponsor hackathon/for apps using OneGeology services.

ACTION: Leah will send list of issues to

5). Adding WCS services

to the OGC services offered by OneGeology for grids, model outputs, 2D slices of 3D models as requested by the OneGeology Board for BGS/BRGM to implement in 2014 (funded). BGS to report on success with WCS 2.0.1 services from GeoServer and proposed way of JavaScript incorporation of such WCS service layers within portal WMS service layers. Discussion with BRGM to take this to implementation. Francois please come to the meeting with suggested date of next major portal changes e.g. WCS support, serving your own projection backdrops with BRGM GeoServer etc.. Steering committee guidance from February meeting: start thinking 3-D, 4-D. How to move to being able to show surface, slices of models, models. This led to interest in Web coverage service. WCS. Remit of OneGeology has been rescoped from 'geologic maps' to 'Geologic Data'.

How to include WCS in portal.

John Laxton; EarthServer project (UK, BGS) to serve coverages. BGS is only working with WCS 2.0. PNG image from GRID. WCS can do grid extraction operations (ex. slice).

Example implemented in OpenLayers with a small amount of javascript.

EarthServer based of rasdaman. Still bit of issues with PNG. Tested GeoServer, MapServer and Rasdaman.

NetCDF is widely used; Australia is serving all geophysical data via THREDDS/NetCDF/WCS

Harvesting capabilities for WCS 2.0 into OneGeology catalog is currently in testing.

Tim D.: BGS -has maintenance contract with GeoCAT for GeoServer maintenance

mandated to test WCS support by Dec 31, 2014

for WCS in portal:

  • support Format=image/png
  • use same keywords ad for WMS
  • add 'One Geoogy WCS layers' to the map layers window.
  • WCS then added in layer switcher
  • no getFeatureInfo or legend. Can get data associated with a point.
  • can add WCS in WMC, but not clear if its possible in KML context.

ACTION: BGS to provide BRGM with example JavaScript for 'getInfo' tool for WCS layer.

BGS will produce data provide cookbook for WCS services using standard server software, and update portal documentation.

When BRGM deliver KML script, can modify so only does WMS 1.3.0. Currently finds a service, writes URL for WMS 1.1.1 into KML script. GoogleEarth now supports WMS1.3.0, so the KML script does not have to find a v1.1.1 WMS. Most servers and clients now support WMS 1.3.0. (discovery of GoogleEarth update discovered by INSPIRE portal; their KML tool only provides WMS1.3.0) WMS 1.3.0 is the version that corresponds to ISO WMS standard. (have to get GoogleEarth working in CRS84 ? WGS84??, or something like that; Ollie couldn't get it to work in the meeting, look at KML generated by OneGeology portal).

ACTION: James and Tim-- figure out how to document setting up WMS 1.3.0 so works with GoogleEarth (or what needs to be done on GoogleEarth side).

  • There is no real support for WMS 1.3.0 in Google Earth, however that doesn't mean that a WMS 1.3.0 only service can't be accessed in/by Google Earth. If you use the Google Earth tools to add a WMS as an image overlay, then what happens in essence is, [1] you specify a service end point, [2] Google sends a WMS 1.1.1 GetCapabilities request to the service to determine image formats supported etc, [3] you select the layer you want to use, [4] Google creates a 'link' that is in essence a GetMap request minus the bounding box request.[5] when you use Google Earth it is this 'link' that is used as the stem of all requests, and the bounding box is tacked on the end. Google Earth requires EPSG:4326 for WMS 1.1.1 requests and appends the bounding box coordinates in this order (remember there is a switch in the coordinate axes order for many coordinate reference systems between WMS 1.1.1 and WMS 1.3.0...) . So the question is therefore, how do you turn a WMS 1.1.1 GetMap request into WMS 1.3.0 GetMap request (sans bounding box), to satisfy the needs of Google Earth bounding box axes order, and the WMS 1.3.0 service? The answer is that you change the version number in the GetMap request to VERSION=1.3.0 and you change the SRS=EPSG:4326 parameter to CRS=CRS:84. An example kml file that adheres to these principles is illustrated below:

%CODE{language="xml"}% From online service (might not display) false false B4FFFFFF http://mapapps.bgs.ac.uk/arcgis/services/INSPIREWMS/Digmap/MapServer/WMSServer?TRANSPARENT=TRUE&CRS=CRS:84&VERSION=1.3.0&FORMAT=image/png&SERVICE=WMS&HEIGHT=1524&LAYERS=GBR.BGS.1:50k.Bedrock&REQUEST=GetMap&STYLES=&WIDTH=1524& onStop 1.0 60.849945 49.902759 2.412245 -8.300482

6). Discussion and review of portal multi-projection capability

New capatility in particular with respect to Arctic and Antarctic projections. There has been much testing and problems identified but it is nearly working – currently; relying on BGS served backdrops – is needed until BRGM have GeoServer in their stack and Antarctic not really needed from BGS as MapServer based and BRGM have the software plus data? Feedback from uses- recent problems identified by GEUS for their Greenland service will be discussed but they are very pleased it is there. Tests from Canada? New Zealand/Australia?

James Passmore demonstrate various projections now availalbe (6 in all): N polar, antarctic, web mercator, WGS84,

New Zealand Southern Victoria service is using EPSG 3031 projection, and it isn't displaying with the antarctic polar stereographic

For south polar base map, see if LIMA can be clipped to got north from S. Pole to 60S; Mark W. likes the Blue marble base map, source is US NSIDC.

ACTION: James will check that New Zealand S. Victoria service has been re-registered, and look into getting Blue Marble base for south polar region.

ACTION: BRGM will deploy base maps for N. Polar region using GeoServer

Arctic base maps originally used was coming from server (MapServer) that was incompatible with GeoServer -based services. Canada data doesn't display because they are using MapServer, and it doesn't correctly render polar regions. problem is when bounding box crosses N pole or get close to -180/180 boundary.

NOTED: GSC please plan to move OneGeology services from Groundwater server to a dedicated OneGeology service using GeoServer (or some other software that works in the polar regions)

Denmark noted problem. At northern end of Greenland, there is a registration error between the Bathymetry and the land area. in the Blue Marble base map image.

ACTION-(James) find a north polar region image base map that doesn't have these problems.

7). Further support for Group WMS services in portal

– report on past use e.g. CIS and possibly GEUS and future requirements raised by VSEGEI – proposed solution to be discussed.

Group WMS service: have hierarchical layers--layers that are composed of other layers. (somewhat unclear if idea that the individual layers are not independently controllable to turn on/off)

VSEGEI service-- multiple images as separate layers in a group. They have made a request to implement a 'secret' layer with tile polygons that correspond to legend images. Will hijack the 'getFeatureInfo' to return html with links to legend from this layer.

DECISION- Francois has some reservations about non-standard behavior, but no one has a better solution. VSEGEI should go ahead and implement and document the getFeatureInfo behavior in the abstract for the service.

current support for Group layers is hand crafted--GeoNetwork can't harvest the Capabilities document.

A group layer doesn't have a legendURL element in GetCapabilities XML schema.

Denmark is using WMTS behind a proxy; this is also causing problems for metadata harvest into GeoNetwork. This is apparently a different problem.

XML schema for 1.3.0 has a style/legendURL for group layers. problem must be in the implementations (MapServer?)

Lars, Marcus, Sylvan, James, Francois say goodnight. Invite Marcus to join on thursday for the transformation discussion. Sylvan will join about 7:30 his time.

8). ESRI_Redlands WFS 2.0 support

in core ArcGIS service – either Satish Sankaran (OGC manager) or Roberto Lucchi (ArcGIS for INSPIRE and WFS 2.0 interest) will join the meeting around 2pm Tucson/San Diego time by gotomeeting to discuss imminent beta release of core ArcGIS server WFS 2.0 capability – with view to supporting user configurable schemas such as GeoSciML 3.2, the onegeology software grant requirement. But if ArcGIS for INSPIRE now part of the onegeology grant from esri should we not be going back to the original aim to support both INSPIRE schema and Geosciml 3.2 schema for onegology in ArcGIS for INSPIRE?

10.3 release is supposed to include WFS 2.0 support as a core offering. No indication that it will do complex features.

By August when 10.3 beta is out, BGS has allocated staff time and a Virtual Machine to test ArcGIS 10.3 with WFS 2 , to see what is working well.

BGS is considering using Clemens' P. software stack for data deliver

Official ESRI contact for ESRI OneGeology grant system to get an ArcGIS license has been in Euorpe.

ESRI has added ArcGIS for INSPIRE to list of software available for the ESRI grants program.

The grant offer is about to be replaced with new grant offer, includes Desktop Advanced, ArcGIS online subscription (5 users 2500 service credits), one copy of ArcGIS server, ESRI Geoportal Server, ArcGIS for INSPIRE. To get have to contact local ESRI distributor, they go to Redlands, Redlands contacts Tim D. to see if provider is legit. Quantity of stuff seems abundant. ArcGIS online doesn't supprt WFS

ACTION item: Tim and Satish spoke by phone just before the meeting, and they will confer in late July by teleconference to discuss WFS 2.0 support in ArcGIS.

9). Production of OneGeology Newsletter

to cover the above developments and portal capabilities.

Production of newsletter end of July or August, following on the letter to surveys pinging people to participate. Need to get message out that Portrayals services add keyword

10). Progress with services

around the world e.g. China and imminent push to the missing '50' geological survey members of onegeology to serve data.

11). Discussion of South America OneGeology meeting

24th October Rio de Janeiro agenda – to include CGI dictionary harmonisation efforts? Encouragement of GeoSciML _Portrayal WMS? GeoSciML 3.2 WFS for querying in portal (Brazil was one of the earliest GeoSciML 2.0 providers) and of course strategy for getting the missing South American surveys to put up WMS services.

We propose the next meeting should be in Lisbon, Portugal, May 2015.

This committee proposes that the 2016 meeting should be in conjunction with the IGC August 2016, Cape Town.

12). AOB

Francois T.: publication of user content in portal in May, 2015, need to decide in September what we want to do exactly. Allow papers to be hosted/indexed in catalog

If Francois T. has extra time he will work on detailing out this problem and looking for a solution.
