Study of Single Network Adjustment Using QOCA Software in Korea
For this study, this researcher conducted a precision
network adjustment with QOCA, the precision network adjustment
software developed by Jet Propulsion Laboratory, to perform an
integrated network adjustment on the Unified Control Points managed
by the National Geographic Information Institute. Towards this end,
275 Unified Control Points observed in 2008 were selected before a
network adjustment is performed on those 275 Unified Control Points.
The RMSE on the discrepancies of coordinates as compared to the
results of GLOBK was ±6.07mm along the N axis, ±2.68mm along the
E axis and ±6.49mm along the U axis.
