gis:set-transformation

gis:set-transformation gis-envelope netlogo-envelope

Defines a mapping between GIS coordinates and NetLogo coordinates. The gis-envelope and netlogo-envelope parameters must each be four-element lists consisting of:

[minimum-x maximum-x minimum-y maximum-y]

The scale of the transformation will be equal to the minimum of the scale necessary to make the mapping between the ranges of x values and the scale necessary to make the mapping between the ranges of y values. The GIS space will be centered in NetLogo space.

For example, the following two lists would map all of geographic (latitude and longitude) space in degrees to NetLogo world space, regardless of the current dimensions of the NetLogo world:

(list -180 180 -90 90)
(list min-pxcor max-pxcor min-pycor max-pycor)

However, if you’re setting the envelope of the NetLogo world, you should probably be using set-world-envelope.
