4.0 Import
4.1 File Import
To get started, the raw XTF bathymetry data
files need to be imported into Perspective using
the
Raw Data File option from the Import menu
as shown in the capture to the right.
Selecting the Import/Raw Data File option will
open a file browser to locate raw data files. A
single file can be selected or multiple files for quickly importing multiple days of data.
4.2 Projection/Datum
If the data was collected in anything other than Latitude-Longitude, the Projection wizard
will launch and ask for the correct projection and datum to use as shown in the following
screen captures.
If the projection used for the raw data files is not present in the standard lists, select
the Custom button to either manually enter the projection values or download a custom
projection string from:
http://spatialreference.org/
A custom datum can also be created by manually entering the datum values. For more
information on using the custom projection and datum options, open the
Help file and look
under Program Settings . Note that the import projection and datum can be preset in the
Projection tab in the Program Settings prior to importing data files or background imagery.
