Climate Scenarios Service Description
The Lifemapper Climate Scenarios Service allows users to get a
scenario or list scenarios that fit desired criteria.
Each scenario is a collection of related environmental layers.
The relationship between the layers is usually defined by a time
period for which the environmental layers are applicable, the
organization that created the scenario, and if it is a future
scenario, the prediction of the environmental scenario. This
predicted scenario could be one which the impact of humans
continues growing at the current rate, reduces, or remains
constant and really anything else along that range.
Getting a List of Scenarios
If you call
http://lifemapper.org/services/lm2/scenarios/xml with an
HTTP GET request, a list of available scenarios will be
returned.
The items returned in this list can be filtered using a number of
url parameters. A full list of the available filter parameters
can be found in the
Lifemapper web services WADL document. You can get an idea
of how the parameters work by visiting the
listing service with
a web browser. A form will be presented at the top of the page
that will allow you to filter the results as well as display the
filters used to generate that page of results.
A common way to use this service is to lookup which scenarios
are compatible. This is particularly useful when you have
determined what scenario you want to use to create a model and
want to find out what scenarios you can then project that model
on to. For this example, we will use the scenario with id 13 as
our model scenario. We would then use the
"matchingScenario" parameter to find out what
scenarios we can use for projections. The resulting url will
be:
http://lifemapper.org/services/lm2/scenarios/xml?matchingScenario=13
.
Another way this service can be used is to determine which
scenarios are current vs. future. For that we need to use
the "keyword" parameter. Current environmental
scenarios use the keyword "observed" while future
scenarios use the keyword "predicted". This url will
return all of the observed scenarios:
http://lifemapper.org/services/lm2/scenarios/xml?keyword=observed
.
while this url will return predicted future scenarios:
http://lifemapper.org/services/lm2/scenarios/xml?keyword=predicted
.
The list of scenarios is available in a variety of formats.
These formats do not contain the actual scenario data, just
metadata about them.
Formats available:
Getting an Individual Scenario
You will need the scenario id number to return an individual
scenario. You can browse the list of scenarios to find the
scenario you would like, and just click the link.
