|The Output Parameters|
The output parameters from dbSEABED are defined in this document.
One-Page Information Sheets
Seabed composition data is complicated. Here are one-page guides to some of the issues and tasks performed in dbSEABED:
|Standardized GIS Legends|
A collection of *.avl and *lyr files which can efficiently be picked up and used in Geographic Information Systems.
is strongly recommended that labs use these standard schemes - liveries
- for quick and accurate visual communication with maps, especially
within the dbSEABED community
- For ArcGIS9.x
- For Quantum GIS (QGIS)
The output parameters from dbSEABED are described with a Semantic Web
syntax. This is suitable for use with applications like SPARQL.
|Random Forests "Painter"|
A Random Forests method of expertly extending - painting - gridded
results from dbSEABED over vast unmapped regions such as the South
Pacific Ocean. While we would prefer that there was more data it is
necessary for some projects to give a current 'best estimate' of
conditions. RF methods boast very high reliability if a proper
technique is used.

|Maximum a-Posteriori Resampler
This tool for 'interpolation' of noisy, heterogeneous data was contributed by John Goff
of UTIG/UTexas, Austin USA. A paper has been published, describing the tool.
|IODP - ODP - DSDP Parameter Sets
For the SEDIS III project the parameter vocabularies of datasets connected with Ocean
Drilling were analysed with a view to rationalization and preparation
for use with the Semantic Web query techologies.
|Interpolator for Marine Substrates
interpolator suitable for mapping marine substrates (ONR Award). Special measures are taken to: interpolate sensibly near
shorelines and through archipelagos, retain the resolution in
well-surveyed areas, avoid spatial biases using isotropic data
selection, quantify uncertainties, validate the grids with
For the Dark Data (NSF EAGER Award 1242909)
a vocabulary of lithology, soils, fluids, ice terms was
compiled which could help locate and rate 'dark' geoscience datasets
from their web presence in metadata or publications. The vocabulary is
also useful for reconciling geomaterials terms between land/coast/ocean
(NSF RAPID Award 1047776 'Seamless over Strandline').
