5. Which map projections do you use?
Answer N° Projections
A EPSG:4326, EPSG:42304
B D48/GK, D96/TM
C Mercator would like support for Orthographic
D EPSG:4326, EPSG: 23031
E EPSG:31467 (Gauss-Kruger zone 3), EPSG:4326 (World Geodetic System 1984)
F EPSG:4326, EPSG:54004, EPSG:900913
G EPSG:4326, PROJ4:"+proj=stere +lat_0=90 +lat_ts=60 +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378273 +b=6356889.449 +units=m +no_defs", PROJ4:+proj=stere +lat_0=90 +lat_ts=60 +lon_0=10 +k=1 +x_0=0 +y_0=0 +a=6378273 +b=6356889.449 +units=m +no_defs", PROJ4:+proj=stere +lat_0=90 +lat_ts=60 +lon_0=20 +k=1 +x_0=0 +y_0=0 +a=6378273 +b=6356889.449 +units=m +no_defs
H EPSG:4326, EPSG:28992. Radardata has a non-EPSG native projection, which is specified by PROJ4: namespace. Consequently the radarservice supports all many PROJ4 projections.

6. Have you encountered any problems with WMS in term of limits or ambiguities of the OGC standard, of performance, of product metadata definition... ? Please describe them and how you solved them.
Answer N° Answer
A Not with WMS per se, but with lack of metadata population in GetCapabilities and FGDC/ISO metadata, which can hinder discovery.
B No
C We would like to have also access control, such as the service can be monitored from where it is used. Is this available in WMS 1.3 ? We would like WMS to support time based access. is this available in WMS 1.3 ?
D We are looking for the best way to use the time variables, which are multiple in meteorology. We are also looking for some way to restrict the access to some layers. Both topics were discussed during the Reading meeting, but only the first one has some solutions
E meteorological time parameters (model-run, forecast-time). In our opinion this is the main drawback so far. Standardization is needed here. Those time-domain standards should be integrated into the OGC reference implementation (geoserver)
F OGC standard – BBOX interaction with the anti-meridian mentioned in 1.1.1 (albeit briefly). Not mentioned in 1.3.0. Performance issues – constantly. Will implement tiling and caching in front of WMS server in Autumn. Product metadata, some problems with update of model runs. If a model “partially” arrived i.e. a subset of expected parameters, the GetCapabilities would report a DIM_RUN available for all parameters. No DIM_FORECAST would then be available. Now supplied with software that can assess availability of each parameter.
G WMS standard issues: A single time dimension is insufficient for meteorological data, dynamic availability of data (list of timestamps of particular data available from the server), unable to filter/search Capabilities, unable to describe cross section coordinate systems. Technical: Poor performance, crash of MapServer over the polar region map requests, unable to read some NWM GRIB files.
H Specification of time and height dimensions. We use now the standard TIME dimension, which does not cover modelruns for example. Performance problems were encountered with large satellite swath products (not solved).
I Specification of time and height dimensions. Dynamic and potential avaibility in GetCapabilities. GetCapabilities layering, Balance Service URL - Layer - Dimensions. Ontology is necessary for keywords, DIMENSION parameters. Performance issue : Tiling and real time meteorological data
J A single time dimension is insufficient for meteorological data. Difficulty in specifying custom projection in request, issues with anti-meridian crossing data and Pacific-centered views.
K Time dimension, Spanning an area across international dateline e.g. Pacific Ocean, South hemisphere symbology -esp. wind barbs, WCS & OPeNDAP integration.
L Time dimension (model run time, forecast time), dealing with multiple vertical dimensions (sigma coordinates, height coordinates), can't specify units, finding an efficient way to handle styling
M Time dimension, ambiguities over what should be done with multiple image returns (composite? last one on top?), palettes (using ncWMS extensions)
N Handling time and height dimensions and some display issues with palettes and scales, most of them solved with ncWMS extensions
O Specification of elevation (when used with height expressed as pressure for instance) and time dimensions.
P No
Q We have two problems regarding dimensions
If a layer has multiple dimensions, it's assumed that all combinations of all dimensional values are available. A layer might have data for time=1990/2000/P1Y where elevation=0, but only 1996/2000/P1Y for elevations 500, 1000 or 2000. We have not found a way to express this dependency between time and elevation in the WMSCapabilities document. A current workaround is to define multiple layers, one where elevation=0 and one where elevation="500,1000,2000"
A layer might have several mutually exclusive dimensions. e.g. a layer might have data for 1000, 850 and 500hPa, and also for 0, 500 and 1000 meters above ground. In this case, the first dimension will be named "pressure" and the second will use "elevation". In this case, the client must include elevation=value OR dim_pressure=value in the GetMap request, but the standard requires the client to include both (unless one or both have defined default values). In this case too, the workaround is to define multiple layers, one for each available dimension

K To date, most of our effort has been to provide services to BOM's registered user community which includes defence and emergency management and local service providers. Effort has been in defining services, naming conventions, symbolization, automation, corporate buy in, support and governance. It is vital that we get a handle on standardisation of symbology and naming conventions if we are to provide global solutions.
While WMS has been great for providing visualization, clients also need to undertake analysis and hence require data via WFS or WCS (which needs more development).
There also needs to be integration between the OPeNDAP / NetCDF and OGC environment. Note that our MapServer environment which is coupled to our Service Information Management System has been an effective solution for the registered user community. We are now using the MapServer and tile cache as a backend to OpenLayers to provide a public view tool. This system is currently being trialled internally
There has been a lot of work recently with GeoServer esp. since the release of 1.7. We will be reviewing GeoServer 2.0 once released and will be happy to share results. Note we currently run GeoServer 1.6 for community schema web services. Recently discussed with GeoServer developers with regard to applications schemas, virtualization (good for non raster data), scripting (now available), web processing service (for integrating and automating business intelligence), SOS and TML (for sensor data feeds), WMS tile server spec (for dealing with n dimensional data), symbology (true type fonts and others), security and performance (comparison with MapServer-which leapfrogs but the two communities are working together) all of which seem very positive.
L This is a big area including many data types. We should look for quick wins and low-hanging fruit
M Mainly interested in dealing with areas of ambiguity or increasing the control over output, but without compromising the ease of use of WMS. For more complex usage, we'd rather switch to another protocol (e.g. WCS/WFS) than change WMS
