Maritime Limits and Boundaries for ArcGIS

The Maritime Limits and Boundaries extension provides a set of tools for calculating maritime limit lines and maritime boundary lines in ArcMap.

Users can capture, configure, store and disseminate their data using an industry leading GIS platform. This is a major advantage to usability as the data stream is harmonized, removing several transformation and data conversion steps compared to other solutions.

Features

  • Advanced limit line calculations
  • Equidistance calculations
  • Weighted midline calculations
  • Tri-point calculations
  • Batch calculation
  • Attribution, metadata and reference to source data
  • Supports shapefiles and file geodatabases

Geocap's extension represents a quantum leap in the science of generating maritime limits and boundaries. For the first time a tool has been created which is capable of accurately computing all the standard maritime zones, plus any customized buffer zones, for a State's entire coastline, in one process.

Benefits

Works directly in ArcGIS

By running these tools inside the ArcGIS environment, users can capture, configure, store and disseminate their data using an industry leading GIS platform. This is a major advantage to usability as the data stream is harmonized, removing several transformation and data conversion steps. Data is read from an ArcGIS geodatabase and the results are stored directly back into the same geodatabase.

Reduced cost and error

Maritime Limits and Boundaries for ArcGIS will handle high resolution datasets, which effectively removes any manual intervention where users previously had to break up the coastline into smaller datasets or decimate the data. To further automate the calculation process Maritime Limits and Boundaries for ArcGIS will ensure that normal and straight baselines can be processed simultaneously. By automating the calculation and removing manual intervention the chance of introducing errors is significantly reduced and staff cost is decreased.

Better data integrity and metadata

By identifying and extracting the critical points and attributes used for generating the different limit Lines, Maritime Limits & Boundaries for ArcGIS effectively links a section of maritime boundary and the coastline used to generate it. This means that for each section of maritime boundary, there is a reference back to the source material, what type of source it is, how old it is and any other available metadata.

Reduced processing time

Processing time is incredibly fast. In a test using the complete baseline found in Australia's publicly available baseline dataset (AMB2006); Geocap's tool completed a 12 and 24nm limit (with 0.1nm vertex spacing) and a 200nm limit (0.5nm vertex spacing) in 10 hours using a standard desktop PC. Preprocessing of the data consisted only of minor attribution modification using standard ArcGIS tools, and no manual intervention took place once the process was started.

Previously this process would have taken Geoscience Australia several years to complete due to the manual intervention caused by the size of the data.
