For a decade we have been working on improving our survey process on every angle as the quality of our surveys is a combination of many things. The used technology needs to be top-notch to be able to gather data detailed enough for our clients. The experienced field crew is needed to ensure that environment of the survey doesn’t affect the survey result. The survey crew has the tricks on their sleeves to tackle challenges brought by weather, water quality and the material or shape of the surveyed object.

The field work has many procedures to ensure the quality of the data. Calibration of survey equipment is a natural part of every project, as well as constant monitoring of the environmental changes, such as temperature and features of water body. The positioning data gathered in the field is used in the post-processing phase, where the details of data are fine-tuned to match our strict criteria.

The path of the data is recorded from beginning to the delivery. Our ISO 9001 certified quality management system includes various checkpoints, where possible errors can be spotted and corrected. The reporting team has expertise in post-processing, point cloud cleaning and 3D data analysis, with capability to many types of modelling and calculations.

Expert analysis points out important observations on the data

We have professional inspectors to evaluate the findings on the survey data. They are educated in analysing 3D data with various tools, and they have wide experience in spotting irregularities on structures. Our online reporting system enables the client also to check the data and use the analysis tools themselves. It is so much easier to communicate the needed repairs with the maintenance team or management when there’s clear data to refer to.

The written inspection report can be downloaded from GISGRO platform easily. We have also updated other downloading options, so that the client can print PDF maps from the platform to share depth charts or dredging plans, for example.

Using the data brings out the value of a survey

The most important feature of a quality survey is how the data fits its purpose. If the data is gathered for maintenance planning, it must be accurate enough and visualised so that it reaches the level of details needed for spotting the risky areas and even the smallest defects. Seabed survey does not need as much details, but you must be able to verify the safety of seaways, detect possible rocks or other objects, and confirm the safe clearance depth.

Usability of the data requires also easy access, so that the data is available when needed without having to send it back and forth with consultants. Modern online platform with tools for analysing the data can be very helpful, as the need for software installations is removed, and the data is accessible simply via web browser.
