= 298.257223563. Because most of our UNO
graduate students on the project were visiting professors
from the ESPOL University in Guayaquil, the name was
dubbed the “ESPOL La Rotonda Grid.” The city has recently
contracted with IGM for a new cadastral mapping system and
GIS. They are continuing with the new Datum and Grid. IGM
is currently participating in the SIRGAS project to establish
a single, unified datum for all of South America using GPS
techniques with technical assistance from NIMA.
U
pdate
Ecuador has been adjusted to the new South American Da-
tum called “SIRGAS95,” Epoch 1995. The original classical
network was re-observed with GPS collocation at 135 stations,
and the Republic now has 35 Continuously Operating Refer-
ence Stations (CORS), managed by the IGM. Transformation
parameters from PDAD56 to SIRGAS95 in Ecuador are not
publically available at the IGM website at present.
