Notes and Changes:
Added excel and pdf of data to convert the local levels to GlobalZ.
Added the Survey notes tying two different datums. This allows the relating of BSC & HAM Chambers to the BTVE mons.
v2--Attached RogersSurveying As-Built for the PSI Monuments
Edited original PDF to included As-Built Coordinates for LVEA in Coordinate table--**There are differences**
VEA pages did not include a coordinate table nor annotation of the PSI numbers. They include symbols for the monuments and they have now been labeled.
Coordinates for the VEA can be gleaned from the As-Built.
Also attaching version A from the old DCC--no real new info but the VEA monument symbols are sized better.
