What is ArcGIS for Maritime: Bathymetry?
ArcGIS for Maritime: Bathymetry is an extension to ArcGIS for Desktop that allows you to serve and use your bathymetric data for a variety of needs such as creating a single composite bathymetric surface on the fly and visualizing multiple surfaces in one frame of reference. The extension also helps you control your hydrographic survey footprints to identify data holdings and see gaps quickly.
Who uses ArcGIS for Maritime: Bathymetry?
ArcGIS for Maritime: Bathymetry is used by several different types of people across many industries and sciences. Data managers, hydrographers, GIS analysts, ocean scientists, and surveyors across ports, ocean science, hydrographic offices, maritime defense, and offshore energy will take advantage of this technology.
How can I organize my data?
You can organize your data using collections (like folders or groups) and by using your own custom metadata for organizing the data. This will allow you to easily search and find data.
What are BAG files, and why would I want to use them within ArcGIS for Maritime: Bathymetry?
BAG or Bathymetric Attributed Grid is a standardized raster format designed specifically for bathymetry. BAGs are rich and self-contained datasets. Inside the same file, BAGs not only store depth data, but they also store uncertainty. So for each pixel, you don't only know the depth of the seafloor, you also have an idea of how much you can trust these depth measurements. BAGs also contain an XML structure of domain specific metadata.
