Method of identifying the location of the survey site

Last Updated June 13, 2024

What is the location of the survey site?

　By matching the boundary point of R Mappy (* 1), the stake on the survey map surface, and the road boundary of both drawings, respectively, the positional relationship between the survey site and the city planning decision line can be confirmed and used for architectural planning (* 2). In addition, when the survey site is far from the road boundary, it is possible to identify the location by using the road waterway boundary survey map, public map, layout drawing of the architectural plan summary book (see document list). There is also.
　Please refer to City Planning Division instructor about questions about identification of position of investigation place.

※１： Boundary points indicate positions such as piles that city establishes as road boundary. Boundaries are determined by various types of marks such as city piles, city tacks, private stakes, points on the figure in boundary survey map, but piles may not exist in the spot.

※２： When submitting the created drawings to the confirmation examination body as attached materials, 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 section by all means if identification of position where you worked was correct.

Points to note when identifying the location of the survey site

Be sure to check the following before proceeding.

・The scale of all drawings used for work will be unified, and the dimensions around the site can be stacked together.
・When specifying the location of the survey site, be sure to match it to be a disadvantageous side (PDF: 706KB) for the survey site.
・Unless two or more boundary points of R Mappy (area map) and one or more road boundary line do not match, the specific accuracy of the location cannot be secured.
(The more matching points and lines, the higher the accuracy of the position identification.)

Method of identifying the position in R Mappie (area map)

Match the boundary point of 　R Mappy (area map) (PDF: 1,368KB) with the stake on the survey map surface, and the road boundary line of both drawings, and identify the location of the survey site.

Method of identifying the position using other materials

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

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.

Please refer to City Planning Division instructor about questions about identification of position of investigation place.

Method of identifying the position in the R Mappy (plan view)

The survey map surface matches the road shape of the R Mappy (floor plan) (PDF: 1,628KB) with the outline of the topographic map to identify the location.

※Because the accuracy of the position in the floor plan is low, there is a high possibility that errors will occur. Therefore, it is not recommended to use it in architectural planning.
