Land Surveying

Measurement is the technology and science to accurately determine the position of the ground or three dimensional space of a point and the distance and angle between them. These points are usually associated with (but are not limited to) places on the surface of the earth. It is usually used to establish maps and boundaries for ownership or government purposes. In order to achieve the goal, surveyors use elements such as geometry, engineering, triangle, mathematics, physics, laws and so on.

Land history and philosophy, measurement and land information systems in North America and elsewhere. Land data system Outline of description and interpretation of land description, data collection method, LIS design, application method. Accuracy assessment, commons and information issues Investigate the management of natural resources and ecosystems and use geography for evaluation and interpretation. Data gathered from various sources, such as remote sensing, ground truth, global positioning system, and databases, are integrated in GIS and are evaluated by examining management and land use planning strategies using image analysis software . Explain the application of environmental impact assessment, environmental modeling, and rapid ecological assessment (REA) in natural resource planning and management decisions.

Measurements were made using a new model developed by the US government. The Public Land Survey System (PLSS) was first implemented in the Ohio River basin in 1785 and set the criteria for land survey at public land. The US Land Management Bureau (the predecessor of land management) began researching the territory of the Orleans region in 1807. Unlike most long-term systems in the Louisiana colony, PLSS divides the terrain into regular grids. Any point on the map can be measured from a fixed vertical meridian and horizontal reference line; in Louisiana these lines are on the west side of 92 ° 24 I 55 II and on the north side of 31 ° 00 I 31 II. By working with basic tools (usually compass and poles and chains), the surveyor continues to block and subdivide parts of the territory.

The Decree of 1785 laid the foundation for land policy until the "Homestead Act" was adopted in 1862. The land rules laid the foundation for the public land investigation system. The first survey was conducted by Thomas Hutchins. After death in 1789, he transferred the responsibility of the survey to the surveyors. The land is systematically surveyed in a square town of 9.7 km (6 mile) wide and is divided into three six sections, each one square mile (2.6 square kilometers) or 640 acres (260 hectares). These parts are subdivided into resale by colonists and land speculators.
