PointSource

Syntax

PointSource(Latitude, Longitude), or
PointSource(Latitude, Longitude, Elevation)

Summary

Allocates all values at a given branch to the map square containing the specified location specified in terms of latitude and longitude.  Note that elevation can also be specified in meters but is not currently utilized in LEAP's calculations. It is important to ensure that the point specified by the function's parameters are located within the shape of the current area (in a one region data set) or among the map squares of the shape for the current region (in a multi-region area).

Use in conjunction with the gridded maps shown in Results View.  This function can only be used in conjunction with the Geography variable.

Latitude values range from -90 (the South Pole) to zero (the Equator) to +90 (the North Pole).  Longitude values range from -180 (west) to +180 (east), with 0 being the Greenwich Meridian and +/-180 being the international dateline. Refer to Wikipedia for more information on latitude and longitude values.
