GeoLab 2-Day Course Outline |
|
| |
|
Introduction |
This two-day GeoLab training program has been
designed to introduce new users of GeoLab Professional
Survey Data Processing software, experienced in the principals
of least squares adjustments, to the software tools and
recommended procedures used for network adjustments.
Students will benefit from a straightforward and practical
approach to setup, adjustment, analysis, and reporting through a series of relevant classroom
exercises.
This hands-on program is divided into 3 modules as follows:
GeoLab Basic - A general overview of the features,
options, input files, adjustment procedures and results
reporting on the adjustment of all of survey data types.
GeoLab Tools - An introduction and overview of the main
GeoLab software tools including the Record Editor, Network
Assistant, Geoid Manager, Station Data Calculator and
Coordinate Transformer.
GeoLab Adjustments - The heart of the program.
Following a detailed review of the survey data adjustment
process, adjustments will be performed on a variety of GPS
data sets. Network simulation for pre-analysis will also be
covered.
