Point Features

Features are used in Perspective to allow the user to import geolocated ASCII data for
displaying locations in the map and profile views, and when relevant vertical information on
the profiles such as from boreholes or cores. In the main map window, there is a

Feature

file tree node where ASCII point data is organized in the project. For viewing the vertical
information (soil type, density, shear strength, etc.) overlaid on subbottom profiles,
options are found in the

Features

tab of the

Profile Settings

dialog.

Feature File Format

The format of the feature files is currently very specific and needs to be adhered to
exactly for the data to be parsed correctly. As shown in the image below, for each point
there are four types of information to be included: location, ID/Date/Time, comments and
depth information.

Although

Features

were developed primarily to display subsurface information on seismic

profiles, leaving the depth information columns blank allows the user to bring in any point
data such as for displaying the locations of SVP and Tide stations, known wrecks in the
area, etc.

For subsurface data, in addition to sediment types any data value associated with depth
can be displayed on the profiles included downhole geophysical measurements, as long as
the data is formatted as shown above.
