List of types

SimpleSDMLayers.SDMLayer Type
julia
SDMLayer{T}

Defines a layer of geospatial information.

The type has two data fields:

  • grid: a Matrix of type T

  • indices: a BitMatrix to see which positions are valued

Each row in the grid field represents a slice of the raster of equal northing, i.e. the information is laid out in the matrix as it would be represented on a map once displayed. Similarly, columns have the same easting.

The geospatial information is represented by three positional fields:

  • x and y: two tuples, indicating the coordinates of the corners alongside the x and y dimensions (e.g. easting/northing) - the default values are (-180., 180.) and (-90., 90.), which represents the entire surface of the globe in WGS84

  • crs: any String representation of the CRS which can be handled by Proj.jl - the default is "+proj=longlat +datum=WGS84 +no_defs", which represents a latitude/longitude coordinate system
