GSI data is transmitted in blocks. Every block consists of several data words,
refer to the examples in the following table. Every data word begins with a two
character Word Index, the WI code, specifying the data type within this block.
Each GSI8 word has in total 16 characters, consisting of 7 information charac-
ters followed by 8 data characters and finally the blank character ASCII code
32. The GSI16 block is like the GSI8 block, but begins with * and the data word
contains 16 characters for large values such as UTM coordinates, alphanumeric
codes, attributes or point IDs.
Example 1 shows a GSI8 block sequence with the words for point ID (11), East-
ing coordinate (81) and Northing coordinate (82). Example 2 shows a GSI16
block sequence with the words for point ID (11), horizontal (21) and vertical
angle (22).
