Vegetation and Surveying

One of many challenges faced when using traditional land surveying methods is the necessity of surveying areas that are covered by thick crops. Some surveying projects require the measurement of such vegetation, while most applications require measurement of the terrain itself, rather than the vegetation covering this terrain. Topographic surveys may or may well not require the measurement of vegetation, depending on their intended goal. Commercial Tree Surveys

When on the floor, land surveyors may find that traditional surveying equipment is blocked by large trees or other items in the way. They may even be unable to traverse the land because of large hills, inconvenient streams, or other natural or man-made features. Combined, these features may make surveying difficult or even impossible from on the land itself, particularly in undeveloped areas. However, there are ways around these obstructions which allow surveyors to create accurate and precise research.

Some methods of surveying can penetrate trees and groundcover. Among these is LiDAR, a laser-based method. Because the laser device is flown within the area in an airplane, it is well suited for heavily rose bush where access on ft . may be difficult or impossible.

Other surveying applications, one the other aspect of the coin side, require measurement of the vegetation. Similar aerial methods do not penetrate forest tops, and therefore can provide an idea of the vegetation while still allowing the surveyor to work from a distance.

1 type of surveying, known as ‘vegetation surveying, ‘ is very enthusiastic about the plants present in a given area. Unlike standard land surveying, vegetation surveying often describes rough boundaries, not stringent lines. Vegetation surveying, or the mapping of herb habitats, is an invaluable tool for botanists, environmentalists, and other earth science applications. Depending after its planned use, a vegetation study may indicate areas with vegetation and those without, or the species of plant and the occurrence and location. These maps may be used to identify sensitive ecological areas (such as wetlands), map the spread of vegetation, or examine environmental changes following natural or man-made events.

In cases where vegetation surveying is desired, measurements may be considered using aerial methods or by using a surveyor’s transit or total station to assess vegetation height also to put out a grid of the terrain, onto which vegetation can be scored. The same grid then can be employed by another surveying team after a time frame to evaluate changes in vegetation and terrain.

While topographical maps may display vegetation or man-made features, a digital terrain model (also known as a digital height model) generally only presents the ground topography and terrain underneath the crops. Digital terrain models may be called bare-earth models, while Digital Surface Versions include features such as vegetation.

There are a number of surveying methods used to create topographic surveys or digital terrain models, such as direct surveying (with a surveyor’s transit or total station) or remote realizing technologies such as high and satellite imagery, LiDAR methods, and photogrammery. The most appropriate method will depend on the location being surveyed and the total amount and type of data required. Some surveying methods used to create these models, such as radar, reflect the best level point on a given location, whether this is the top of a tree or building or bare ground, although some are planned for the measurement of the terrain itself.
