Subject: 	Shapefiles for Australia/New Zealand Treaty lines

Three shape files covering the points and lines for the Australia/New Zealand Treaty. 

The SHP file of the points has the following attributes:

F_code = indicating whether the point is a Treaty point or not
ANZ_id = the unique Australian identifier
NZ_id = the unique New Zealand identifier
LONGITUDE = longitude in decimal degrees
LATITUDE =  latitude in decimal degrees
LONGDEG = full degrees of longitude
LONGMIN = full minutes of longitude
LONGSEC = decimal seconds of longitude
LATDEG = full degrees of latitude
LATMIN = full minutes of latitude
LATSEC = decimal seconds of latitude

Two SHP files for the lines are attached with one for MacquarieNZ and the
other for NorfolkNZ. The line attributes are as follows:

Aus_start  = the identifier for Australian point at start of the line
Aus_end = the identifier for the Australian point at end of the line
NZ_start = the identifier for the NZ point at start of the line
NZ_end = the identifier for the NZ point at the end of the line
Line_type = indicating whether the line is a geodesic or and arc

Please note that in the nornz file Point 1 has been included as a vertex
within the line from Point 0 to 2. Similarly for Point 17a in the line from
Point 17 to 18 in the macnz file.
