Topographic surveys used for design and planning
A Topographic map is a site map that illustrates both natural and man-made features of a project site depicted through the usage of contour lines, spot elevations and cad descriptions. Generally these types of surveys are provided to engineers, architects, geologist, and building contractors for design and building purposes. This means that we will collect any information that might affect the site design. Some examples of natural features include drainage patterns, rock outcroppings, hills, ditches, slopes, wetlands and vegetation. Man made features can include buildings, above and below ground utilities, channels, roads, walkways, parking lots and more. Topographic contours can be shown at any interval that is specified by the client. In areas of steep terrain a larger contour interval can show the topography without crowding the map that would be introduced by a smaller contour interval. In areas of relatively flat terrain, a smaller contour interval is necessary to show the detailed changes in topography in a meaningful way. For smaller sites, the information may be gathered by traditional survey methods using a conventional total station, robotic total station or real-time kinematic GPS. For larger sites, it may be more appropriate and cost-effective to use aerial mapping methodology.
