Topographic Surveying Services

GEOTECH deal with configuration, relief, or three-dimensional characteristic of the earth surface, that show topography together with natural and artificial feathers such us lakes, building, and highway thus we determine the configuration of the earth surface and locate natural and cultural feathers on it.

Methods

Aerial
we use Aerial photographs to determine, areas,for topographic mapping,
Transit-Stadia
Distance, elevation and location measurement are taken in the field recorded the filed book and then plotted on paper.
Plane table
transit-stadia method except that the data id plotted in the field on paper attached to the drawing board mounted on a tripod.

Controls

Topographic surveys require horizontal and vertical control, we use these controls for the basis of topographic survey measurement, control will be reflected in the error in the position of topography.

Horizontal Control

  • Two or more points on the ground and precisely fixed in position by distance and direction.
  • The basis for map scale and locating topographic features.
  • Horizontal control for topographic work is usually established by a traverse.

Vertical Control

  • benchmarks in or near the tract to be surveyed
  • Foundation for correctly portraying relief and elevation on the map.
  • lines of level starting and closing on benchmarks.

GEOTECH3D employs a full-time professional staff enabling us to provide a full range of professional surveying services, boundary and topographic surveys, construction stake-out and monitoring & environmental mapping are some of the services we routinely provide to our clients, maintain the latest, most advanced field equipment and process the data with the most powerful modeling software available in the industry.

Applications:

Planimetric Ground Survey:
GEOTECH operates state of the art with Evolution softcopy workstations to extract planimetric and topographic features, and an array of software tools for generating and processing contours, map formats, and symbols.
 
Volumetric Survey
Deliver Accurate Volume Calculation Reports Volumetric is useful for any project where shaping and shifting are required and are especially valuable for quarries, golf courses, reservoir design, and landfills.
 
Setting Out:
External and Internal Survey, Buildings, apartments, landscaping, Lands, fences, Once the design is done, we can provide precise horizontal and vertical control for the construction of buildings, roads, utilities, and other improvements.
 
Façade Survey
When dealing with build heritage and subsequent conservation and preservation issues many of our clients require a higher level of detail than is usual for façade and building surveys.
