TOPOGRAPHY AND GEODESY

Topography

Topography is the basis for all infrastructure, construction and development projects that are generated around the world. That is why it is important that the topographic survey is carried out as accurately and carefully as possible. Our team has training and the software with the best results on the market, which allows us to offer our clients the best cost effective solution.

Topography, planimetric survey of the perimeter and the interior of a natural gas measurement station.
A topographic survey consists of describing a terrain from a topographic point of view. Through the use of specialized instruments, the surveyor scrutinizes the land surface and proceeds to collect data, generally with a total station and / or GPS / GNSS receivers. With the data obtained in the topographic survey, maps or specific plans of a place are made, particularly describing the characteristics of the terrain, such as reliefs or differences in height that may exist.

 

With this topography technique the main objective is to determine the position of the terrain between two points, on a horizontal plane. Here the planimetry comes into operation, which is defined as the process of representing a piece of land on a plane at scale. Therefore, in this phase, elements such as height and relief are dispensed with.

Subsequently, on the basis of the horizontal plane, the direct leveling method is used to determine the height of the ground between various points. In this leveling, we start from a point whose height is known, to proceed to the vertical measurement of the height of the ground, thus being able to establish heights or the identification of various points or coordinates.

Types of Topographic Surveys

Depending on your particular needs, you may require the services of our topographic study to obtain:
 

Cadastral Surveys

This type of survey is used to obtain a measurement of the limits of the land for its cadastral use.
 

Urban – Rising plans

Urban topographic surveys or plans are carried out on properties belonging to municipalities, requiring greater precision in the measurement. They are usually required by an architect, real estate, etc., to know the exact measurements of a home or building.
 

Topographic surveys for engineering projects

Another use of this method is its use for the establishment of the starting bases of engineering projects, especially related to the construction of infrastructures, being of use required by engineers, architects and builders.
 

Topographic surveys with drones

Topographic surveys with drones do not replace conventional topography by themselves, they are a support tool used mainly for surveying large areas such as mines, land, industrial parks, etc. Data from 300 hectares can be obtained in just 40 minutes without sacrificing precision, as long as there is an adequate and corrected ground control against INEGI’s RGNA. In addition, it is complemented by drone photogrammetry to broaden the perspective of the decision-maker of a project.

Geodesy

Geodesy is at the core of the GeoEarth, being this our greatest tool when it comes to its application in different projects, with it the real shape of the earth is considered, so its application in linear projects of more than 5 is essential. km or in applications of large extensions. It requires knowledge of the various coordinate systems used and the ability to apply the one that best suits the customer. All projects that require geolocation have a geodetic base so their applications are immense.
