6. Land levelling

The loose soils may settle differently depending upon equipment travel or depths of irrigation water applied. Consequently, a major land levelling operation will correct the macro-topographical problems but annual levelling or planing is needed to maintain the field surface by correcting micro-topographical variations. 6.3.5 An example problem Get price

Aerial Surveying with Land Surveys

The relatively small and easy to operate aerial platforms can be transported easily and used to capture imagery of small specific areas that would be uneconomical or impractical to cover with a traditional manned aerial survey. These aerial images are then quickly processed and transformed into meaningful outputs such as high resolution Get price

Photogrammetry for UAV Surveying and Mapping

Aerial surveying, however, is a different story. While many of the above strengths still apply, aerial photogrammetry has historically had one clear bottleneck: the aircraft itself. Renting an airplane with a specialized aerial camera could often negate photogrammetry's key strengths – they are expensive, troublesome to mobilize, and Get price

Surveying, a means of making relatively large-scale, accurate measurements of the Earth's surfaces.It includes the determination of the measurement data, the reduction and interpretation of the data to usable form, and, conversely, the establishment of relative position and size according to given measurement requirements.

Drone LiDAR or Photogrammetry? Everything you need to know

Jan 06, 2018In photogrammetry one of the critical parameters required to process the data accurately is image overlap that should be at the level of 60-90% (front and side) depending on the terrain structure and hardware applied. The typical LiDAR survey requires only 20-30% overlap between flight lines, which makes the data acquisition operations much faster. Get price
