Hawaii Pacific GIS Conference 2012: 3D GIS - Creating Bathymetry Maps with Coarse Data - Bayesian Kriging Using Open Source Tools
1. Creating Bathymetry Maps
With Coarse Data -
Bayesian Kriging Using
Open Source Tools

2. 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
3. Outside the United States…
Most countries do not have a spatial
data repository where bathymetry
data, land cover data, etc. is readily
available to be used for analysis.
4. 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)
