FAQ
Frequently asked questions
Who determines the contour interval?+
The interval is selected according to the site area, its terrain and the level of detail required for the study.
Does the service include preparing the complete hydrological study?+
This page covers the survey and supporting surveying outputs; any additional engineering scope is expressly defined in the quotation.
Can a drone be used for the survey?+
It may be suitable for large sites; its use, together with control points, is assessed according to site conditions and the required accuracy.
