Photogrammetry and conventional surveying comparison

There are diverse ways that the height and horizontal locations of land are calculated. It can be via conventional land surveyor in Tuncurry or some other. When procuring design data it is imperative to consider factors that will establish which method is better than another. A short description of each method is elucidated below along with the relevant pros and cons.

THE CONVENTIONAL SURVEYING

This is the old-school method. Conventional surveying of landscape is performed by inspection crews using a theodolite or level to study dimensions. These are the surveyors you see working meticulously along the side of the road or at building sites.

The advantages of conventional commercial or residential boundary survey Tuncurry consist of:

·         A visual check of the area

·         Proven methods of verifying accuracy

·         The most exact way to measure altitude of geographic features such as streams or ditches.

Disadvantages comprise of:

·         Line-of-sight barriers such as buildings or vegetation

·         Slower acquisition of data

·         Labour intensive and costs

PHOTOGRAMMETRY- for Contour survey in Tuncurry

Photogrammetry is normally used on larger land regions and is the technique of making measurements by using aerial photography. Huge panel points, which can be seen from the air, are marked typically using GPS tools. Flight patterns are then mapped out and high resolution cameras are fitted on air planes to take overlapping photos of a site. Through the use of computers, a 3-dimensional replica is generated depicting the vertical and horizontal changes on the land.

Advantages consists of :

·         big amounts of data can be obtained rapidly

·         decrease in costs per acre due to less physical labour

·         Accurate locations of strongly developed property

·         Photogrammetric locations of location features

Some disadvantages are:

·         Line of sight difficulty (typically caused by both low and elevated level vegetation)

·         Reductions in exactness due to vegetation

·         Inability to actually notice the ground surface along ditches and streams

·         Time of year restriction due to vegetation

Boundary survey cost Tuncurry

There are land surveyor costs in Tuncurry if you choose photogrammetry but it can be comparatively lesser than traditional survey methods. Use any method but weigh all the pros and cons and then come to a fine conclusion.
