Calc Destination Map

Description

This functor calculates destination cells taking into account some measure of attraction, as depicted on an attractiveness map. Non-null value cells represent selected destination cells.

Inputs

Name	Type	Description
Attraction	Map	Attractiveness map. Values equal to or less than zero will be ignored.
Horizontal Quadrants	Positive Int	Number of horizontal segments into which the attractiveness map is divided.
Vertical Quadrants	Positive Int	Number of vertical segments into which the attractiveness map is divided.

Optional Inputs

Name	Type	Description	Default Value
Minimum Distance Between Destinations	Non Negative Int	Minimum distance buffer between adjacent destinations, in meters, is used as a constraint to impede the selection of additional destinations within this buffer.	0
Maximum Attempts Per Destinations	Positive Int	Maximum number of draws realized in order to pinpoint a valid destination.	15
Destinations Per Quadrant	Non Negative Int	Maximum number of destinations chosen in each map quadrant.	1
Cell Type	Cell Type	Data cell type of the output map.	Unsigned 8 Bit Integer
Null Value	Int	Null value of the output map.	0
Destination Is Sparse	Bool	If true, map of destination is represented as a sparse image. Sparse images have the advantage of storing only the cells containing non-null values, but they have worse access time.	True

Outputs

Name	Type	Description
Destination	Map	Map depicting destination cells. Destination cells are depicted using their attractiveness value. Map has the same dimensions of the attractiveness map.

Notes

The number of destination cells is specified by the number of destinations per quadrant but not all potential destinations may be selected because some map regions do not show attractiveness greater than zero and some potential destinations are located within the minimum distance buffer.

An attractiveness value represents a probability of a cell to be selected based on some desired quality.

The attractiveness map must have integer values.
