Topographic surveys
What we Offer?
Accurate cartography and digitisation
Topographic surveys are carried out to digitise and georeference water supply and sanitation networks, delivering accurate CAD/GIS plans for efficient network management.
Field data and characterisation
An inventory of network elements (material, diameter, dimensions, depth, among others) is carried out to generate reliable and useful information for maintenance and control, through field data capture using high-precision topographic equipment.
GIS maintenance
Continuous updating of the graphical and alphanumeric information of the networks, avoiding the need to repeat surveys, reducing costs and facilitating decision-making.
High-precision technology
Centimetre-accurate topographic equipment is used to guarantee location accuracy and the reliability of the delivered plans.
FAQs
When is a topographic survey required?
A topographic survey is required when planning construction works, network maintenance or infrastructure map updates. It enables the generation of reliable digital cartography and network plans for accurate decision-making.
What is the cost of a topographic survey?
The cost of a topographic survey depends on the size of the area, terrain complexity and client requirements. A customised topographic survey quotation is offered, including digitisation and delivery of plans and data in PDF and GIS formats.
Why is it important to keep a GIS updated?
An up-to-date GIS provides an accurate overview of networks and infrastructures, ensuring that graphical and alphanumeric information reflects reality, avoiding errors and duplicated surveys, and optimising management and planning.
Can surveys be carried out in areas with difficult access?
Yes, classical topography is combined with advanced technologies such as drones and laser scanners. The latter is used on an inverted tripod, allowing access to complex or hazardous spaces such as wastewater pumping stations, ensuring safe data capture.
