7.1 Cultivated Field Control
7.1.1 Introduction
CFC or Cultivated Field Control is a GS20 application aimed
at providing an accurate record of crop quantities and
tolerance in accordance with European Union CAP subsidies.
A user can collect and select a polygon, and calculate the
area with an error estimate corresponding to a user-defined
tolerance. Additional functionality also allows the user to
subtract areas within the external area, and save the
subsequent data to a text log file that can be exported to a
personal computer.
CFC is an additional application that will require a keycode
file. To purchase the application and receive a keycode,
please contact your local Leica representative.
7.1.2 Setup
With the possibility to use a mask file, the application is open
to a variety of output into different ASCII file interfaces. The
mask file *.MAS is a simple ASCII text file to be opened with
any text editor on a PC.
• The @LEICA CFC MASK@ is the identifier for any mask
file.
• The @@@ is the identifier for the end of the mask file.
• The lines between the both identifiers are restricted to an
amount of 15, each line with 80 Characters maximum.
• The @00@ until @99@ are placeholders for the numerical
values or code/ attribute info. This gives full and easy
flexibility to create different output masks for any ASCII type.
• A sample Leica.mas file (right) is provided and can be
edited to the needs of the user.
