HISTORY OF SURVEYING

Search history of induction search

Research is traditionally defined as the science and art of identifying or determining the relative location of points above, above or below the surface of the Earth.

The first investigation day 1400 A. C.

The Egyptians used it first to divide the land strictly into shares for tax purposes. 120 a. The Greeks developed engineering and used it in the proper division of the Earth. The Greeks developed the first research team (diopter). Standard Greek procedure for conducting investigations.

Day of Initial Research • 1800 m

The beginning of the Industrial Revolution. The importance of "exact boundaries" and requests for general improvement (for example, railways, canals and roads) lead the investigation to a prominent location. More precise tools have been developed. She has developed geodesy and weather research.

 Research today's affects almost everything in our daily lives. Some of the areas where research is used are: • Earth map above and below sea level. • Preparing the navigation map (land, air, and sea). Set limits for public and private lands. • Developing a database for natural resource management. • Developing technical data to build El camino bridges. Building land development

Five main research areas

Research, analysis and decision making. • Field work {data acquisition}. • Computing {data processing}. • Mapping {data representation}. Staking out



Two main research methods • Geodetic research


Pay attention to the theoretical form of the Earth. Generally high precision and covers a large area. (More than 300 square meters).

Search for a plane

Let's say the search area is flat. It usually covers a small area (less than 300 square miles). The most used method.

Types of research

Search Control Ground. Topography of lands, borders and cadastral area. The original search looks for subdivisions. Hydrographic survey. • Research route. • Research construction. • Custom searches. Mining Research

The United States government regulates the investigation.

An accurate assignment cannot be made without good control. The horizontal and vertical geodetic control network continues to expand and renewed throughout the country.



 • National Geodetic Research (NGS) • Land Management Office (BLM) • United States Geological Survey (USGS) • Defense Assignment Agency (DMA). • The engineering agency of the US Army. UU. Where they will take it in the future


The land is in the early stages of a revolution in the way data is collected, stored, retrieved and shared. • Computers are widely used at all levels. • Optical system. • Satellites are used to record all types of physical data. As comedian Stephen Wright said: A friend sent me a postcard with photos of all the planets taken from space. On his back he says: "I hope you're here."
