Folder View For a spatially aware profession we have a strange view of file storage!

iphoto - Even my home computer has better spatial awareness!

IT naughty chair! The problem

DO WE PRODUCE SEABED MAPS OR CHARTS? WHAT TYPES OF PRODUCT DO WE NEED TO CREATE?

Advantages Structured system Consistency Quality Control Scalability (single file to Enterprise) Integration (CAD, Fledermaus, Kingdom, FME) Sharing (e.g. via FME Spatial ETL) Time / Cost effective

Inputting data into the BIS Bathymetric Attributed Grids (BAGs) are referenced rather than duplicated.

Creating a BIS and Setting Up Collections

Loading the BIS

Using the BIS Viewing data by vessel Hydrographic Survey consisting from 4 different vessels

Using the BIS Viewing data by vessel Data just from Survey Vessel Ping by filtering the other three vessels out

Using the BIS Combining datasets to create one huge surface Rules used to define how the surface is built; Newest first, highest accuracy, IHO Order number, Type of sonar.

Using the BIS Combining datasets to create one huge surface

Geospatial tools can then be applied to the one surface Usage: Route surveys, Pipeline surveys, Very large area surveys
