GOFC
Data Portal
The portal
is divided according to the three main GOFC themes. It provides
users with an interface to specify search criteria which include
region of interest, temporal window, and predetermined keywords.
A user can define his region of interest by selecting from
a list of locations, or drawing a rectangle on a map.
The GOFC
Data Portal provides a view of the International Directory
Network (IDN) customized to meet the requirements of the GOFC
Implementation Teams and Regional Networks. Scientists can
use the portal to browse the directory and search the distributed
databases. It will evolve over time as GOFC develops new projects
and products. Note that currently very few datasets are actually
produced by GOFC, but this portal provides the capability
to look for datasets that are relevant to GOFC's concerns.
Of the
thousands of collections which are listed on the IDN, the
datasets that match the search criteria will be returned back
to the user. Information returned from the search contains
metadata, which describes the identification, the quality,
spatial reference, and distribution of digital geographic
data. If there is any product level data available on Internet,
the user is able to conduct a distributed search. Thumbnail
and browse images will be returned with the metadata, if available,
and can be used to evaluate the product. Some products also
provide a link to download the data.
