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.
