Chapter 3 Importing and Exporting
DelphMap can import a number of different types of files as layers to form
imagery. DelphMap can also export layers as a single file, making the result easy
to work with as a single entity.
Importing Files of Different Resolutions
Files of different resolutions can be imported into DelphMap. These include
bathymetry, mosaic images and seismic profiles. For example, a mosaic image
file with a resolution of 0.25 m can be inserted into a DelphMap project that
contains a mosaic image with a resolution of 0.20 m and a bathymetry layer with
a resolution of 0.5 m. The resolution displayed under Project
→Project
Information will be that of the layer with the highest resolution in the current
DelphMap project.
Importing Different Kinds of Files
Certain types of files must be imported in a special way so that they can be
redisplayed properly in DelphMap. These include contact files, pipeline or
pipespan files, seabed classification files, ASCII points with labels, seismic profile
files, and photo image files. Once a file is imported, it becomes part of the
composite image appearing in DelphMap’s main display window. Other types of
files planned for later importation into DelphMap are pipe span files and
classification files.
Photo image files are of type PCM (Pulse Code Modulation). For further
information about importing a photo image layer, please contact TEI Technical
Support (831.722.7373).
Importing a Background Image
DelphMap can import the following files types as background layers:
TIFF
BSB
If you have an appropriate background image that has the same kind of
geodesy as other layers that either are or will be present in your imagery,
you can enhance your displayed imagery in DelphMap by importing a
background image into your project. A background file can either be a
geoTIFF file or an electronic nautical chart (BSB format).
