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.

 

Topographic & Utility Surveys

Topographic and utility surveys are those that represent the existing site conditions of an area. They serve as the basis for most engineering design, planning, and architectural projects. Because so many other professions will rely on the base map it is extremely important for it to accurate, follow proper CAD standards, and to be delivered on time. 3D Surveys approaches each project individually and will determine the most efficient field data collection method based on the project's requirements. We utilize robotic total stations, photogrammetry or GPS and other methods as needed. The final product is delivered as clean 3D CAD files (including DTM data) and as .pdf and paper prints as needed. These surveys often include topographic contours and spot elevations, site features such as structures and roads, above ground and underground utilities, trees, wetlands, pile volumes, and more.
