Specify the COORDSYS clause to note that the data is not stored in longitude/latitude form. When no COORDSYS clause is specified, data is assumed to be stored in longitude/latitude form.

All coordinates are stored with respect to the northeast quadrant. The coordinates for points in the United States have a negative X while coordinates for points in Europe (east of Greenwich) have a positive X. Coordinates for points in the Northern hemisphere have a positive Y while coordinates for points in the Southern hemisphere have a negative Y.

type is a positive integer value representing which coordinate system to use

datum is a positive integer value identifying which datum to reference

unitname is a string representing a distance unit of measure (for example, ¯m" for meters); for a list of unit names, see Set Distance Units

origin_longitude is a float longitude value, in degrees

origin_latitude is a float latitude value, in degrees

standard_parallel_1 and standard_parallel_2 are float latitude values, in degrees

azimuth is a float angle measurement, in degrees

scale_factor is a float scale factor

range is a float value from 1 to 180, dictating how much of the Earth will be seen

minx is a float specifying the minimum x value

miny is a float specifying the minimum y value

maxx is a float specifying the maximum x value

maxy is a float specifying the maximum y value

paperunitname is a string representing a paper unit of measure (for example, ¯in" for inches); for a list of unit names, see Set Paper Units

tablename is the name of an open table

window_id is an Integer window identifier corresponding to a Map or Layout window

A performs scaling or stretching along the X axis.

B performs rotation or skewing along the X axis.

C performs shifting along the X axis.

D performs scaling or stretching along the Y axis.

E performs rotation or skewing along the Y axis.

F performs shifting along the Y axis.
