A topographical survey is a set of operations performed on the ground, with the necessary equipment and using appropriate methods, designed to take sufficient data to allow us to represent the terrain and the position, shape and dimensions of all natural/artificial elements on it.
It is one of the most common topographic tasks, and intends to represent the ground tachymetry elements (planimetry + altimetry) essential to the intended purpose. To carry it out, there will usually be an office work prior to field work, in preparation for this, then a field study, and last some further work cabinet.
Surveys can be of various types, including:
- General type: They are intended to mark or locate boundaries, measure and divide surfaces, locate plots of land on general shots linking with previous surveys or project works and constructions.
- Longitudinals (communication roads): They are used to study and build transportation routes (roads, railways, transmission lines …)
- Urban and cadastral: They are made in urban areas to set boundaries and to study the urban area in order to have background information for urban planning.
The most common works that we carry out include:
- Measurement of properties and plots of land.
- Specific surveying applications for agriculture: ground leveling, new irrigation lines staking, etc..
- Segregations, subdivisions, fusions…
