Usage Overview
ICAN's Survey Module has been designed to address the needs of the marine survey
market. The survey pattern generator creates route templates consisting of a
series of configurable parallel lines. The user provides the endpoints lat/longs
and a series of pattern parameters. The surveyor then generates the grid. The
user can then create a route based on this survey pattern.
Surveys are a series of parallel route legs generated automatically by
Regulus II and Aldebaran II. The legs of the survey are generated in relation to the
first leg. This first leg is created either by designating the two endpoints of
the leg as Lat/Long points, or by designating the start point of the first leg
and then a length and initial course for the first leg. As noted above, the
other legs are then generated parallel to this first leg by supplying values for
the total number of legs, the spacing between them and the direction of the
first turn. The surveyor can also designate values for the allowable cross-track
distance (XTD) and waypoint alert distance.
A new custom data format has been added to ICAN's Survey Module. MRE, or
Modified Run-length Encoding, is a custom format developed to display TIFF
images produced from side-scan sonar surveys. MRE's come from Georeferenced TIFF
files. MRE files are produced using the TIFF-MRE converter. This converter is a
separate program activated from within ICAN's ECS.
