A CDF data set using ISTP/IACG guidelines, by definition forms a logically complete and
self-sufficient whole (data and descriptions).
The goal is to make the resulting CDF data set correctly and independently usable by the science community and accessible through the CDAWeb Display and Retrieval system.
intended for first time users or anyone wanting only an overview of the process of creating a CDF data file.
Descriptions of the whole data set.
Defines data variables, support_data variables, and metadata variables including their dimensionality and what is needed for their correct display.
List and definition of attributes describing each variable.
intended as reference material. Valid values for one of the variable attributes (DICT_KEY) are given including class and subclass keywords, and the uses of a Data Dictionary are described.
intended as reference material. Example skeleton tables and skeleton CDFs are included.
, which is a JAVA downloadable program that aids the user with the creation of a Skeleton CDF.
Use IDLmakecdf program produces a CDF file using IDL with a Skeleton CDF file and user-supplied IDL code to read user data.
Use makeCDF program produces a CDF file (using C) when given 3 input files: (1) data file, (2) translation file, (3) Skeleton CDF file.
Use generic CDF software and write your own program.
