Lifemapper Services lm2 A group of algorithm parameters are the values of the algorithm parameters used. /helpAlgoParams.shtml get post algoparams True http://lifemapper.org/services/lm2/algoparams An experiment is a grouping of a model and all projections built off of it. The Lifemapper pipeline generates experiments based on unmodeled taxa as well as models that are out of date. In addition, users can submit their own experiments with the parameters tuned to their liking. /helpExperiments.shtml get post experiments True http://lifemapper.org/services/lm2/experiments Environmental layers are raster data files representing some region of the world. Each cell in the layer is a measurement of the parameter associated with the layer (ex. average temperature). /helpLayers.shtml get layers True http://lifemapper.org/services/lm2/layers Models are rulesets created by applying an algorithm to a set of occurrence points over a scenario of environmental layers. There are several different algorithms that generate models in different ways. Some operate more quickly, such as Bioclim, and some can take quite a bit of time depending on algorithm parameters (GARP Best Subsets). /helpModels.shtml get models True http://lifemapper.org/services/lm2/models Occurrence sets are groups of occurrence points. They are generally all from the same species, but do not have to be. They should, however, be related enough that creating a model would make sense. For example, if you wanted to create a model of prey for a certain species, you could create an occurrence set of all of the points where any of those species occurred. /helpOccurrences.shtml get post occurrences True http://lifemapper.org/services/lm2/occurrences Each projection is an application of a model on a scenario. A model is a ruleset that is created by applying an algorithm to a group of occurrence points and a scenario. The resulting projection is a raster layer that can be used as an environmental layer in another model. /helpProjections.shtml get projections True http://lifemapper.org/services/lm2/projections 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 on that range. /helpScenarios.shtml get scenarios True http://lifemapper.org/services/lm2/scenarios
