From Ocean Teacher LibraryMarine Data Visualization Tools
Historically -- and especially now that computers play a central role in marine data management -- the analysis of data has centered on visual displays, including more-or-less "standard" figures such as station maps, station profiles, scatter plots, sections, gridded and contoured scalar values, vectors of currents/winds, etc. These analyses are inextricably linked with all aspects of marine science, ranging from initial quality control procedures to all levels of hypothesis testing and research. We present here only a small selection of programs, namely those used in OceanTeacher.
|ArcExplorer, Java Version|| Browser/viewer for existing local Geographic Information System (GIS) data, with a web client for viewing online GIS data |
Basic Radar Altimetry Toolbox. Designed to use radar altimetry data. It is able to read all altimetry data from official data centres, from ERS-1 and 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, Jason-2 and Cryosat, from Sensor Geophysical Data Record to gridded merged data; to do some processing and computations, and to visualize the results.
| EnviView|| Allows Envisat data users to open any Envisat data file, and examine its contents. It provides simple visualisation capabilities, and allows data to be exported to HDF for use in other software packages|
|Google Earth||Very imaginative 3-D geospatial data viewer, tied into many major online data and image systems.|
| G.Projector|| Java application which transforms a global input equirectangular map image into one of over 80 global and regional map projections|
Grid Display and Analysis System for gridded meteorological and oceanographic weather and climate data, usually in GRIB or NetCDF formats
Browser/viewer for Hierarchical Data Format (HDF) files; can convert other-format data to HDF. Very useful for browsing unknown datafile, especially suspected binary grids.
Browser/viewer for data in Hierarchical Data Format (HDF) and now also NetCDF. Handles Level 3 and 4 satellite products very well, but the wide variety of HDF variants used for Level 1 and 2 products requires the use of specialty remote sensing software. This should not be a problem for general marine data management operations, whereby usually only Levels 3 and 4 are maintained. Useful for exporting grids from HDF or NetCDF in ASCII format, and also for creating HDF files from existing image files.
|Integrated Data Viewer||Data visualizer for remote sensing images, GIS files and a broad suite of operational ocean and weather data products|
|Mozilla Firefox||Internet website browser recommended for use with OceanTeacher Wiki|
|ncBrowse||Browser for NetCDF files with limited graphic analysis capabilities|
|Ocean Sneaker's Tool||Spreadsheet-type program to generate, illustrate and visualize table-organized geo-referenced ASCII data; can convert Seabird CTD data to ODV spreadsheets|
|Environmental Data Connector|| Provides a GUI to browse THREDDS catalogs or OPeNDAP directories, to subset the selected data in space and time, and to download the data as a netcdf file.|
|Ocean Data View||
Analysis and display software for ocean station data; produces publication quality graphics.
A Java application which plots geo-gridded arrays from netCDF, HDF and GRIB datasets; subsetting by geographic coordinates is supported
Very basic gridding program that operates in XYZ files, producing contoured grids; can also create motion vectors from speed and direction grids
| Saga ||
A hybrid GIS software incorporating robust gridded display handling with a somewhat lesser-developed shapefile management and display capability
