Tripod Data System

TDS (Tripod Data Systems) is a technique designed to use your handheld devices as rough as you can to make it compatible with intense external environment. They also provide the versatility in the range of friendly software for the mobile computing and for various industries as well.

This format is designed to work with these devices and espacially with Survey Pro software.

The format is a comma separated ASCII file containing record types, headers, recorded data and comments.

Each record is made of one line of text, with comma-separated fields of ASCII text format:

AH,DC%s,MA%s,ME%s,RA%s

This format is the base of other formats :
