3. Having added these parameters in the
LAYER METADATA
mapfile section,
the WMS
GetCapabilities
response should change. Now, the hotspots
layer definition includes the time dimension, defined by the
<Dimension>
and
<Extent>
elements. You will get a response as follows:
<Layer>
<Name>hotspots_time_series</Name>
<Title>World hotspots time
series</Title>
<Abstract>Active fire data detected by
NASA Earth Observing System Data and
Information System (EOSDIS)</Abstract>
<SRS>EPSG:4326 EPSG:3857</SRS>
<LatLonBoundingBox minx="-180"
miny="-90" maxx="180" maxy="90" />
<BoundingBox SRS="EPSG:4326"
minx="-180" miny="-90" maxx="180"
maxy="90" />
<Layer queryable="1">
<Name>hotspots</Name>
<Title>World hotspots time
series</Title>
<Dimension name="time"
units="ISO8601"/>
<Extent name="time"
default="2011-10-01"
nearestValue="0">2000-01-01/
2020-12-31</Extent>
</Layer>
</Layer>
4. You can finally test the WMS service with time support. You only need to
remember to add the
TIME
parameter in the
GetMap
request (otherwise,
GetMap
willfilteroutthedatausingthedefaultdate,whichis
2011-10-01
,
in this example) by using this URL:
