Types

type Raster

type Raster struct {
	Names  map[string]*Taxon // a map of name (in lower caps) to taxon
	Fields int               // number of fields in the raster bitfield
	Pixel  map[int]int       // map of pixel:bit
	Cols   int               // number of columns
	Fill   int               // fill of the raster
	Resol  float64           // resolution of the raster
}

A Raster is a rasterized data set.

Rasterize creates a new raster from a given dataset.

func (*Raster) Taxon

func (r *Raster) Taxon(name string) *Taxon

Taxon returns a taxon for a given name.

type Taxon

type Taxon struct {
	Name string
