Chapter 8 Display and Level Operations

LTPlus, by design, conducts its basic operations on any given map in pixel
coordinates.  However, it provides the user with the opportunity to perceive
movement within that same map in as many as 17 different coordinate unit types,
as listed  below.  The current coordinate unit type will be identified in
screen tile 2 (upper-left window).  Not that the user may define special
coordinate types.  User-defined coordinate systems may be established and
stored in the config file (see config).

coord_type
    
    Defines the cuurent units of display and input.

         coord_type c

    Defines the current, active units of display and input.
    ___________________________________________________________________________
    Options/arguments:

         c         Units of measurement, where:
                        0 =  Raster pixels
                        1 =  W. Longitude, N. Latitude (ddd/mm/ss.ss) 
                        2 =  UTM meters
                        3 =  State Plane feet
                        4 =  Digitizer1, absolute coordinates 
                        5 =  Digitizer2, absolute coordinates 
                        6 =  Map inches
                        10-19 = User-defined units
    ___________________________________________________________________________
    Example(s):

    To establish display and input units as ground feet in the State Plane
    Coordinate System, enter:

         coord_type 3

    To set raster pixels as the units for display and input, enter:

         coord_type 0
