Description of the Geo Data Portal from the Geo Data Portal documentation home :

The USGS Geo Data Portal (GDP) project provides scientists and environmental resource managers access to downscaled climate projections and other data resources that are otherwise difficult to access and manipulate. This user interface demonstrates an example implementation of the GDP project web-service software and standards-based data integration strategy.

A user of the GDP interface can supply their area of interest as a pre-existing GIS shapefile with one to many unique polygons or by drawing a single polygon using an interactive web-map. A user can select from available GDP project web-service processing algorithms, which include raw data subsetting. returning a NetCDF. or file and area-weighted statistics summarization, returning a text file of summary time series.

Processing algorithm options such as dataset component of interest, time period of interest and output file formatting must be specified. As the GDP project progresses, other processing algorithms and output formatting options will become available. Datasets available from the initial public release of the portal include historic weather and downscaled climate projections.

As the GDP project progresses, the catalog of data available from the portal will expand to include more climate, weather and geographic data resources. In order to allow processing of very large datasets, GDP project web services perform asynchronously. This allows a user to supply an email address and be notified upon process completion.

Descriptions of the 2012 CDI-funded projects (from the FY12 CDI Annual Review):

ScienceBase - Geo Data Portal (GDP) Integration Support
The purpose of this project was to develop efficient and effective ScienceBase features that leverage the data integration framework and tools developed for the GDP project. It also aimed to create a greater awareness of the ScienceBase system and GDP tools and what they can do for science teams around the bureau. Finally, input from usability testing to feed back into the projects for improvement according to the needs of real users were compiled.

Benefits

Enable USGS science integration with Climate Science Centers, Landscape Conservation Cooperatives, etc.
Results in cooperation between ScienceBase and GDP development teams

Deliverables

Presentation given at CDI-hosted Webinar (September 2012)
CDI Training Opportunity: ScienceBase and Geo Data Portal
3 two-day sessions were completed in Sept, 2012

Python port of Geo Data Portal (GDP) client tools (WPS) with hooks for ArcGIS Toolbox
The proposal will increase the functionality of the GDP. The GDP, developed by USGS’s Center for Integrated Data Analytics, provides a powerful functionality to process climate and other large remote gridded data, returning summary statistics and areal tabulations over user specified areas. Currently the user interface is an interactive web form, returning a CSV table. This work would allow ArcGIS, Python, R and other common scientific client applications users to access this functionality directly via a GDP Python module.

Benefits

Enables scientists to bring subsets of climate models and other GDP data products into their GIS workflow
Will allow summary of landscape, weather, and climate data available via GDP data integration framework web services
