Advantages of Using Remote Sensing Data
Remote sensing data of very high and high resolution can be obtained more quickly as they may already be available in the operator's archives, and new imaging does not require any approvals from competent authorities. Suitable for creating 2D models (regional models).
Satellite imagery does not require on-site visits, unlike aerial imagery and UAV-based imaging.
Aerial imagery allows obtaining images with high spatial resolution (up to 1 cm/pixel) and provides a higher level of detail for orthophotoplans and models, achieving a root mean square error (RMSE) of coordinate determination of less than 10 cm, and can be performed below solid cloud cover. Aerial imagery is suitable for creating highly accurate CMM and CMR. Suitable for creating 3D and 2.5D models (urban models).
