Web Map Service (WMS)

Time and Elevation

Time/elevation for vectors

● Single time (instant) support● Interval validity support by selecting two

attributes● "Current" time always up to date

● Currently investigating integration with measured geometries and dimension based slicing

Time/elevation for rasters

● Image mosaic with time/elevation attributes in the tile index

● Tile index in shapefile or database● Automatic extraction of time/elevation

from file names via regular expressions

Time and Elevation

...&request=GetMap &time=2001-08-01T18:00:00Z/2001-09-01T00:00:00Z

But... why limit animations to just to time and elevation?

Web Feature Service (WFS)

WFS 2.0

...&request=GetFeature&startIndex=5&count=6&...

Paging

WFS 2.0

<wfs:CreateStoredQuery> <wfs:StoredQueryDefinition id='bbox'> <wfs:Parameter name='AreaOfInterest' type='gml:Polygon'/> <wfs:QueryExpressionText returnFeatureTypes='topp:states'> <wfs:Query typeNames='topp:states'> <fes:Filter> <fes:BBOX> <fes:ValueReference>the_geom</fes:ValueReference> <gml:Envelope> <gml:lowerCorner>${x1} ${y1}</gml:lowerCorner> <gml:upperCorner>${x2} ${y2}</gml:upperCorner> </gml:Envelope> </fes:BBOX> </fes:Within> </fes:Filter> </wfs:Query> </wfs:QueryExpressionText> </wfs:StoredQueryDefinition> </wfs:CreateStoredQuery>

Stored Queries

...&request=GetFeature&storedQueryId=bbox &x1=-180&y1=-90&x2=180&y2=90

WFS 2.0

<fes:Filter> <fes:PropertyIsEqualTo> <fes:Function name="strMatches"> <fes:ValueReference>name</fes:ValueReference> <fes:Literal>name-f002</fes:Literal> </fes:Function> <fes:Literal>true</fes:Literal> </PropertyIsEqualTo></fes:Filter>

Extended Operators

<fes:Filter> <foo:strMatches> <fes:ValueReference>name</fes:ValueReference> <fes:Literal>name-f002</fes:Literal> </foo:strMatches> </fes:Filter>

Referencing

NTv2 and NADCon support● Support for high accuracy datum

changes based on datum shift grids● Error down from 4m (if you're lucky) to

few centimeters

○ NTV2: canadian grid shift standard, used in Europe and Australia too

○ NADCon: american grid shift standard

● Support for official EPSG grid files● Ability to add your own custom ones

(work in progress)

Reprojection console

● Reproject single point or geometries● Check what exact transformation is

being used

Un-referenced data

● Serve unreferenced data:○ CAD data (floor plans and the like)○ large photos

● Made up new code to handle such data: EPSG:404000

Data access

Database level security

WFS sorting and paging

● Available in all WFS versions (in 1.0 and 1.1 as a vendor param, startIndex/maxFeatures)

● Native, most efficient in spatial databases● Emulated in all other data sources

(suitable for smaller data sets)

New experimental OGR store

● OGR: rich set of readable formats● Does not need special bridge libraries

(uses BridJ to connect to native lib)● Slower performance than native Java

formats, suitable for smaller data sets

Image collection store

● Publish collection of non georeferenced images via WMS (eventually time varying)

● List and search provided off band as a separate tool

● One layer, select image with CQL_FILTER
