Broken linear reclassification model
This is a model type which applies a reclassification on one map using a broken linear curve.
Classification model (single grid)
This a model type which applies a reclassification on one map using a classification table. For example, all values of the input map between 0 and 1 will be 0 in the result map, all values from 1 to 5 will be 0.5 and all values larger then 5 will be 1 in the result map.
Classification model (multiple grids)
This is a model type which performs a reclassification with more then one map as input using a classification table. For example a result map has to calculated taking into account the values of several maps. For example, if map1 has a cellvalue between 0 and 1 and map2 has a value of 10 then in the result map the cell should get the value 100.
Direct effects
These are is for example: the grazing by birds or land use management by mowing.

Indirect effects
These are all the effects via the environmental conditions.Environmental conditions
Folder
A Folder This is used to structure your own project to your wishes. A folder can contain others folder or a group of scenarios. For example you can use a folder to structure you scenarios for different areas. This could be a folder including scenarios and models for the lake IJsselmeer and one for the Waddensea.
Formulas
These which can be used in the Formula-based calculation are all the PCRaster functions. This varies from a simple abstraction and multiplication to more complex neighborhood functions. Additional functions of PCRaster can be found here
Formula-based calculation model
This is a model type which allows you to operate math, multivariate and neigborhoud functions on one or multiple grids. It also allows you to make queries (using the 'if-then-else' function).
Map contents Anchor
This can be used to view maps, compare values of multiple layers of maps and view and edit legends of maps. It is also possible to add a background map.

PCRaster
This is the map calculation tool used by HABITAT. PCRaster is developed by PCRaster Environmental Software/Faculty of Geographical Sciences, Utrecht University (Copyright ©1987-2003). PCRaster can be obtained from www.pcraster.nl.

Reclassification
This is a map operations that takes input cell values and replaces them with new output cell values. For example, assigning a value of 1 to cells that have values of 1 to 50, 2 to cells that range from 51 to 100 and so on.
Response curves

The measured or modelled dose or conditions is generally plotted on the X axis and the response (habitat suitability, costs, damage) is plotted on the Y axis.
