Topographic surveys are essential for
determining a land's geographical condition. The data can be useful when
identifying maps and determining the contours of a land. Topographic surveys
are crucial during the planning stage of any construction or developmental
project. The contours and maps created during the survey will serve as the
basis for the project, whether it be a developmental structure, road, bridge,
commercial, or residential structure.
Topographical surveys can be conducted
below and above ground level. Walls, wells, manholes, utility poles, soil
density, walkways, and trees are among the elements and areas that will be
covered during the survey. Each aspect or material found on the land will
contribute to a topographical survey's outcome. The following steps are usually
involved in a topographic survey:
- Establish
vertical and horizontal control to serve as the survey's framework.
- Determine
ample horizontal elevation and location of ground points to provide enough
data, which will be essential for plotting as soon as a map is prepared.
- Locate
man-made and natural features that may be covered based on the survey's
purpose.
- Compute
angles, elevations, volumes, and distances, of the earthwork.
- Draw the topographic map.
The outcome of the topographical
survey should reveal various details about your land. Likewise, the results
are useful in determining the land's cultural and natural features. The data is
essential for determining the value, life, and strength of the land. The
breadth, length, height, curves, height, elevation, and other factors that need
to be measured will be calculated, and each surveyed aspect should contribute
to the land's map and contouring.
Topographical surveys can be applied to a
variety of situations. The results are useful for engineers, geologists,
foresters, land promoters, architects, and government institutions and
agencies. Topographic maps are used as guides for creating the land's actual
geographical map, too.
