GeoBASIC is a programming language for L
EICA
theodolites and their simulation
on personal computers. The core language appears similar to today's common
Windows BASIC dialects, thereby it is easy to learn and use. However,
GeoBASIC's main power lies in its ability to use many of the existing theodolite
subsystems and dialogs, just by calling an appropriate built-in function: for setting
parameters, measuring, geodesy mathematics, and many things more. These tools
at hand, the programmer can quickly and flexibly build sophisticated geodesy
applications.
The user manual first describes the installation of GeoBASIC on a PC (
Chapter 2
Then, after learning how to create an GeoBASIC application (
Chapter 3
), it will
be shown how to actually load and execute a program on a L
EICA
theodolite
(
Chapter 4
) and on the Windows simulation
(Chapter 5)
.
As these technicalities are mastered, the main topic is programming in GeoBASIC.
This manual will give you several hints on typical GeoBASIC programming
(
Chapter 8
), and introduces you to the design and programming of the theodolite
user interface and refined GeoBASIC concepts (
Chapter 9
Finally
,
GeoBASIC example programs are presented (
Chapter 10)
. The reader will
find a sample code for measuring and computing the mean value of several
horizontal angles. Moreover some introductory examples are given to tell how
special problems can be treated.
Note
All the details of the GeoBASIC language and system functions are
composed in the "GeoBASIC Reference Manual".
