Surveying can also be disruptive and requires formwork such as scaffolding, which is costly and time-consuming. With road construction and tunnelling projects, for example, lanes are generally closed and scaffolding is erected or elevated work platforms used so that geologists can reach the cliffs that they need to measure.
Manual mapping processes also face challenges in terms of consistency, sample sizes and quality issues associated with the repetitive nature of data collection tasks.
Thanks to technological advancements, however, land and rock surveying are being transformed by digital mapping. Under this concept, technologies such as drones and UAVs are sent into remote or difficult to access environments to capture data often over a large area. Continue reading here
