[G01-5-03] Japan-1sec1cm accuracy -Geodetic Network Adjustment
Having learned from Kobe Earthquake (1995) and East Japan Earthquake (2011), future solutions are proposed on satellite surveying, satellite image photogrammetry. Parameter Estimation Gnss Assisted SUrveying System (PEGASUS for short) realizes 1 sec 1 cm accuracy geodetic network adjustment for earthquake monitoring. Now in Japan Basic Act for National Resilience Contributing to Preventing and Mitigating Disasters for Developing Resilience in the Lives of the Citizenry (Act No. 95 of December 11, 2013) has started, and for application of land administration systems, like Cadastre2014, Land Administration Domain Model Standard and Social Tenure Domain Model, we prepare for reconstruction plans, using 4D Image Map Archive Designed Aerial Survey (IMADAS for short) technology and German AAA Land Information System.
Kumamoto and Tottori earthquakes in Japan in 2016 motivated nationwide geodetic network adjustments, 1 sec 1 cm accuracy approach, for earthquake monitoring in 3D displacement in the world geodetic datum. We tested feasibility of such 1 second GNSS geodetic network adjustment to forecast the earthquake deformation of monitoring points. For reconstruction process after earthquakes to determine parcel points in real time 3D mapping of reconstruction projects, with 1cm accuracy on the ground, we could combine high resolution 3D satellite stereo models and precise drone photogrammetry.
Now we add 1 sec 1cm accuracy geodetic networking for Southeast Asian counties, such as Cambodia, Myanmar and Bangladesh, for land administration and cadastral projects in real time mode (FKP) and in seismic monitoring mode (GEONAP) for UN-GGRF initiative.
