Tsukasa Consulting Co. in Japan uses the TatukGIS Developer Kernel (VCL edition) to develop its M System 3D GIS software solution that is used to manage radioactive decontamination work being performed in the vicinity of the site of 2011 Fukushima Daiichi nuclear power plant accident.
The major earth quake and tsunami on March 11, 2011 severely damaged the Fukushima Daiichi plant, resulting in widespread leakage of radioactive material which forced 300,000 residents in Fukishima Prefecture to flee their homes, becoming refuges. Today the Japanese government is engaged in a massive decontamination effort with the objective of decontaminating – house by house and parcel by parcel – 105 affected cities, towns, and villages, to allow residents to return to their homes. The effort involves 10,000 – 20,000 personnel and a budget of $3 – 4 billion annually.
The work of Tsukasa-Consulting involves the mass production of detailed, structure-by-structure, 3D maps of decontamination areas by using hybrid 3D vector plotting process with stereographic viewing of aerial imagery. The result is highly accurate, +/- 10 cm, 2D and 3D vector objects representing each building structure within a mapped area. The process is cost effective relative to laser scanning methods, taking advantage of already existing data, technology, and knowledge, and resulting in smaller datasets requiring less processing and editing. Bentley Systems MicroStation software is used to generate the 2D and 3D vector models (as DGN files) that are used in the M System software developed using the TatukGIS SDK. The M System solution enables decontamination teams to optimally plan their efforts before entering radioactive zones, know the number of houses in an area, identify structures with contamination, assign personnel to individual houses, and manage the progress using a 3D GIS enabled database system.
The Tsukasa 3D plotting methodology, editing tools, and M System GIS enabled database management software were presented by Tsukasa Consulting Co. CEO, Hamamoto Takashi, at the recent SPAR Japan conference on June 3 and 4 in Kawasaki, Japan. This presentation can be viewed at the link: https://youtu.be/C91oSpFrq64
Besides the Fukushima decontamination project, the Tsukasa tools and methodology are targeted to areas including environmental maintenance, architecture, energy (solar panels), prevention and recovery planning of natural disasters, managing of building plans and records, and urban planning.
