Ocean scientists are beginning to incorporate the
use of GIS into data visualization, data management and analysis. At NOAA’s Pacific Marine Environmental
Laboratory (PMEL), software tools have been developed to help scientists
select, process and convert their in-situ data sets into a GIS-usable format. EPIC is a tool that allows scientist to
manage, display and analyze CTD, XBT, time series and bottle data. Access to
PMEL’s data repository is available via the World Wide Web. The EPIC Web Browser allows users to select
data using various search criteria.
Once data are selected, users may display the data and download the data
for conversion to a GIS format. The
conversion of data uses a JAVA application developed at PMEL. Csv2shp allows users to convert .csv files
to an ESRI specified shapefile format independently of the ESRI software environment.
Climatologies
and other gridded data sets are available for download from PMEL using the Live
Access Server. The Live Access Server
(LAS) allows users to connect to remote data servers using a seamless web
interface. LAS interface allows users to
select data by geographic region and by variable type. Data are available for download as either
ascii text or ArcView Grid Format to add to ArcView or ArcMap sessions.
Ncbrowse
is a software application developed at PMEL that allows users to browse netCDF
files, subsetting the data and saving the data to a text file that can be
converted to a shapfile. Ncbrowse
allows GIS users to explore their data in 1and 2 d space.
In this
presentation, we will create a GIS project using tools developed at PMEL and
provide links to other research groups working to make oceanographic data
accessible to the marine community.
