A survey may be done on a property, piece of land, a coastline, or even a building. In general, surveying determines the two or three-dimensional points on the surface of the Earth and the angles between them. These points allow a map to be created or a boundary to be established. Aside from this technical aspect, research is also involved in surveying, such as gathering observations, using questionnaires, collecting data analysis, and consulting the legal history of the property or land.
If a survey is needed for your Connecticut property or land, a combination of these techniques are used. While research procedures remain the same, the technical aspect of measuring points has evolved. Instead of relying on manual techniques, surveyors looking for an accurate picture of your Connecticut property or land will use laser scanning.
Laser scanning involves the technique of capturing the data of a surface with a laser. This allows complex surfaces to be surveyed easier and takes less time than traditional methods. A return survey is rarely needed. For a survey on your Connecticut property, land, or building, laser scanning is likely used.
For the laser scanner to generate a computerized image, the device sends out a laser beam in the direction of the object and measures the time the beam takes to return. This distance produces a point on a three-dimensional graph (X, Y, and Z coordinates), and the device proceeds to send out thousands of beams in the direction of the object. The result is a point cloud on the graph, which is assembled in to a computer-generated, three-dimensional image.
The three-dimensional image, however, is not the end of this Connecticut survey. Two-dimensional images need to be created, and the three-dimensional image serves as reference for these. For buildings and maps, two-dimensional drawings from multiple angles can be produced from the three-dimensional image.
