The ArcGIS for Maritime: Bathymetry 10.3 expands the BIS’s capabilities beyond supporting raster datasets. Users can now utilize the solution to store and work with bathymetric point feature classes!
All of the existing possibilities for filtering and applying surface modeling rules based on metadata characteristics to develop surface models can be applied to point feature classes. In addition, the release also includes two new geoprocessing tools to help users maximize the value of using their bathymetric point data within the solution.
The Export Points tool extracts points from the surface model based on the applied rules and writes those points to a new feature class. When two or more of the point datasets in a surface model overlap, the tool uses the feature classes’ footprints to only export point from the dataset with the highest priority ranking in the surface model based on the ordering rules.
The Bathymetry toolbox also now includes Reduce Point Density. Reduce Point Density uses the user-defined thinning distance and outputs a point feature where no point in less than the minimum distance from another point. The output maintains the most significant points in a datasets, and can is be either shallow or deep biased depending on the user’s preference. Users can also specify a thinning distance that varies as a function of depth, so that the output may be sparser in deep waters, while maintaining more density in shallow waters.
The release is part of our commitment to support the maritime community’s work. Over the next few weeks, we will be releasing a series of blogs covering new features in the release in more detail.
