Creating Bathymetry MapsWith Coarse Data -Bayesian Kriging UsingOpen Source ToolsHal KoikeUniversity of Hawaii,Hawaii Fisheries Cooperative Research Unit
Why do we need a Bathymetry Map? Marine resource management is pushed toward ecosystem based management (e.g. linking with land development, marine protected area) You need spatial data to fully understand the ecosystem of your interest Species distribution for marine organisms is known to be influenced by depth
Outside the United States…Most countries do not have a spatialdata repository where bathymetrydata, land cover data, etc. is readilyavailable to be used for analysis.
If $$ is Limited, What are the Options? Stick with what you have Create a pseudo-bathymetry map Some budget friendly data covering the world (bathymetry case) Navigational chart (low cost) MODIS (free) Hyperion (free)
