Functions in NicheA

  • Create a background cloud (BC)

    • You can use an existing BC configuration to create a BC, or draw a BC with two or three environmental variables directly.

  • Create a virtual N

    • Generate a new N by an ellipsoid, polyhedron from background cloud or another N.

    There are several ways to create a N. This section shows how to generate a N via create an ellipse/ellipsoid in 2D or 3D space. The following sections shows how to generate a N via other functions.

  • Generate N(s) from occurrences

  • Generate N(s) from MVE

  • N attributes

  • Quantify niche overlap

  • Design barriers

  • Principal Component Analysis

  • Raster conversion

  • Threshold calculator

  • Export N to ENM

  • Occurrence statistics

  • Virtual species - parameter

  • Variables statistics

  • Read data from multiply raster files

    • Read values from a group of layers with fixed longitude and latitude coordinates.

  • Variable normalization/standardization

  • Set NoData value

    • Reset the GeoTIFF file’s NO DATA value.

  • Convert points to raster

    • Convert a CSV file with longitude and latitude list to a raster file.

  • Calculate AUC value of partial-area ROC approaches

  • Calculate AIC/BIC value

  • Change the range of ENM's result
