5.4 Logging Data to a File
The Asset Surveyor software logs GPS positions, offsets, external
sensor data, and attributes for GIS features to data files. You can have
a number of data files on your TSC1 datalogger at once, but you can
only log GPS data to one data file at a time.
Note – You can view a second rover or background file as the
background for the map, but you cannot select or edit any features
from this file.
Data files are classified as rover, base, or background files. A rover
file contains feature and attribute information, together with the GPS,
offset and external sensor data associated with each feature. A base
file contains only GPS base station data. To create base files, select the
Create base file entry from the Data collection menu.
A background file is a data file that you may want to view on the map,
but which you do not want to edit. Importing such a file as a
background file means it is safe from accidental updates.
If you select Data collection from the Main menu, the Asset Surveyor
software displays the Data collection menu:
