1. Binary to Decimal Conversion for LCI IETF 67 – GeoPriv WG 11/06/2006 San Diego

2. What is it? draft-schnizlein-geopriv-binary-lci-00 “This document describes the nature of the data expressed in the geographic LCI defined in RFC 3825, and includes examples of conversion from its binary format to decimal character strings. “

3. LCI “The LCI encodes a point's latitude, longitude and altitude, along with the resolution of that point. LCI does not encode boundaries of an arbitrary region. The resolution is nothing more than the representation of significant digits for the fixed- length, binary values in the LCI. “

4. Programming Hints/Examples C code examples need to be tested. Example of binary math to determine the LCI value and resolution given a range.

5. List Comments Expressing resolution of the significant bits in a fixed-length binary value is not the same as geo-coordinate measurement errors – (ex. 38.9 does not equal 38.9000000) –RFC3825 uses FIXED-LENGTH fields, which implies the need to express resolution other than as a variable number of significant digits.

6. List Comments No example of the xml (pidf-lo) wrapping the decimal-string value is necessary. Appendix A of pidf-lo profile incorrectly characterizes LCI This draft does not change RFC3825
