Blocks

All information are structured in blocks, i.e. in main blocks and sub blocks where:

•      Each block starts with a block heading

•      Each block ends with an ”end of block” –identifier or a new block heading.

•      A number of standardised block headers/identifiers are defined

Three main blocks are defined: The Heading, Text and Data blocks. The main block identifiers are:

•      [BOH], [EOH] (begin of heading, end of heading)

•      [BOD], [EOD] (begin of data, end of data)

•      [BOT], [EOT] (begin of text, end of text)

In addition identifiers for the start/end of the information is defined as:

•      [BOF], [EOF], (begin of file, end of file)

For the main block: Heading, the following sub blocks are defined:

•      [Common] (includes definitions how to read data)

•      [Station] ( geographical information, parameter information)

•      [Grid] (similar to [Station], however data are described in a grid net)
