YOUR DATA: Data Formats and Data Access for the IDV

An IDV user can

• use data files in NetCDF format for point observations, 2 - 3 - and 4D grids, tracks, and other types of data .
• put point observations (scalar, vectors, and special geophysical observations such as seismic focal mechanisms) into ASCII "csv" files,
• other formats the IDV reads, such as GIS "shape" files, JPEG, TIFF, geo-TIFF, DEM
• use online data access from web servers, catalogs, and WMS servers, without concern about data format.

Making Your Data ready for the GEON IDV

To format data for the GEON IDV:

• Learn how to make files in NetCDF (detailed description). and NetCDF 2D and 3D grids.
  
• If you have data already in ASCII row-column formats, you can convert them to NetCDF using
  UNAVCO's ASCII to NetCDF data reformatters .
  
• Learn how to put point data values into ASCII csv files,

Data Access for the GEON IDV

The GEON IDV can access data from

• Local files on disk
• files on a web server -- files with a URL on an HTTP web page. (The file must be NetCDF files or other formats that the IDV can read.)
• OPeNDAP servers.
• listings in "catalogs." Catalogs are an online service with listings in plain-language categories, that hide file names and individual URLs of the files. Catalogs are intended to be more informative and useful than filenames with URLS.
• WMS sites (web map servers).

Data on a OPeNDAP server, WMS server, or on a catalog must be in the right format; not any data on such servers works!.
