Topographical reference - Road number - Dunkirk Urban Community
Description
This repository consists of more than 70 layers of topographic data describing plots, buildings, green spaces, roads, urban furniture, hydrography and toponymy. Characteristic levelling points (wire, high and low slopes, carriageway axes, high point / low point ) also provide information on altitude.
This 2D reference system consists of the integration of precise topographic and parcel plans (very large-scale 1/200th scale detail plans ). The classes of details in accordance with the Order of 16 September 2003 are as follows: 4 cm in planimetry and 2 cm in altimetry.
The plans are carried out by expert surveyors or by the surveyors of the CUD by traditional method (field survey by tacheometry ).
This invisible line is used to add textual information about the road represented.
