Method to identify the location of the survey site [R Mappie]

Last Updated December 13, 2024

What is the location of the survey site?

　By matching the boundary point (* 1) of R Mapppi with the pile on the survey map surface, and the road boundary of both drawings, the positional relationship between the survey site and the city planning decision line can be confirmed, and it can be used for architectural planning. (* 2). In addition, if the survey site is far from the road boundary, it is possible to identify the location by using the road waterway boundary survey map, official map, layout drawing of the architectural plan summary book (see the list of materials). May be.
　Please refer to City Planning Division instruction section about question about identification of position of investigation place.

※１： Boundary point shows positions such as piles that city establishes as road boundary. In the boundary survey map, boundaries are determined by various types of signs such as city piles, city studs, private piles, and points on the map, but piles may not exist in the site.

※２： When submitting the created drawings as attachments to the confirmation and examination organization, please attach them as explanatory materials such as drawings when specifying the location of the survey site. In addition, about city planning facility under business, please refer to City Planning Division by all means whether identification of work position is correct.

Points to note when identifying the location of the survey site

Be sure to check the following before working.

・Unify the scale of all drawings used for work, and make the dimensions around the site overlapped.
・When specifying the location of the survey site, be sure to match it to be a disadvantageous side (PDF: 706KB) for the survey site.
・If two or more boundary points of R Mappie (area map) and one or more road boundary lines do not match, the specific accuracy of the position cannot be secured.
(The more matching points and lines, the higher the accuracy of the position is.)

Method of identifying position in R Mapy (area map)

The boundary point of 　R Mappie (area map) (PDF: 1,368KB) matches the pile on the survey map surface, and the road boundary of both drawings, and identifies the location of the survey site.

How to identify positions using other materials

　If the survey site is far from R Mappie (area map) and the location cannot be specified only with R Mappie (area map), it is necessary to identify the location using other materials.

Materials that can be used to identify the location of the survey site

The materials that can be used to identify the location are as follows.

Please refer to the pdf file for the location identification method using each document.

How to identify position in R Mapy (plan view)

The survey map surface matches the road shape of R Mappie (floor plan) (PDF: 1,628KB) with the outer shape of the topographic map, and identifies the position.

※Since the specific accuracy of the position on the floor plan is low, errors are likely to occur. Therefore, it is not recommended to use it in architectural planning.
