What is the block reference point?
The block reference point is a survey reference point (detic results 2000) developed by the Ministry of Land, Infrastructure, Transport and Tourism as part of the “Basic Survey on Urban Renewal Blocks”. Installed in the area.
From April 1, 2008, the management authority of the block reference point established in Yokohama city has been transferred from the Ministry of Land, Infrastructure, Transport and Tourism to Motoichi.
What is the basic survey reference point (Basic Survey of Public-Private Boundary in Urban Areas)
The basic survey reference point is a survey reference point (detics results 2011) developed by the Ministry of Land, Infrastructure, Transport and Tourism as the basis for cadastral surveys, and is installed in the Kamagaya district, Kanazawa-ku.
※Yokohama City Public Control Point (Getting Results 2011) is managed by Road and Highway Bureau. Specifically, please see "page of road investigation section".
Handling of survey results associated with the Tohoku-Pacific Ocean Earthquake
Regarding the block reference point in Yokohama City, it is the result of the geodetic results 2000 at the time of installation, and will not be revised to the results after the earthquake.
Inspections are performed as before, but the use of the survey results has not been approved.
Points to be managed
Land Registry and Survey Division manages block reference points established by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). "Node" and "Auxiliary points" are not subject to management because they are temporary points, and are abolished on the same date as transfer to Motoichi.
Of the basic survey reference points, "basic triangle point" and "basic polygonal point" are also subject to management.

Most of the block reference points and basic survey reference points are installed on the road, so they may be affected by road excavation work. Therefore, we have established the "Yokohama City Block Reference Point Management conservation Guidelines" which describes procedures for general handling of block reference points and management conservation, etc., and strive to properly use block reference points.
