Aeromagnetic surveys are widely used to aid in the production ...Image inview UAV medium.jpg right thumb The InView UAV is starting to be used in aeromagnetic surveys. An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft. The principle is similar to a magnetic survey carried out with a hand held magnetometer, but allows much larger areas of the Earth s surface to be covered quickly for regional reconnaissance. The aircraft typically flies in a grid like pattern with height and line spacing determining the resolution of the data and cost of the survey per unit area . As the aircraft flies, the magnetometer records tiny variations in the intensity of the ambient magnetic field due to the temporal effects of the constantly varying solar wind and spatial variations in the Earth s magnetic field , the latter being due both to the regional magnetic field, and the local effect of magnetic minerals in the Crust geology Earth s crust . By subtracting the solar and regional effects, the resulting aeromagnetic map shows the spatial distribution and relative abundance of magnetic minerals most commonly the iron oxide mineral magnetite in the upper levels of the crust. Because different rock types differ in their content of magnetic minerals, the magnetic map allows a visualization of the Structural geology geological structure of the upper crust in the subsurface, particularly the spatial ... where bedrock is obscured by surface sand, soil or water.

  1. Systematic survey

    Systematic survey or extensive survey is the archaeology archaeological technique of detailed examination of an area for the purpose of recording the location and significance of archaeological resources. It provides a regional perspective by gathering information on settlement patterns over a large area. It is one of the basic fieldwork strategies used by paleoanthropologists and archaeologists . The regional survey answer questions pertaining to the site s location, the size of the settlement, their types of buildings, and the age of the site. Usually the surveyor walks over the area and records the site locations and their size. During this process, the surveyor tries to date the site to see when it was occupied.

Using Hubble s law , the redshift can be used to calculate the distance of an object from Earth. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter within a field of the sky. These observations are used to measure properties of the Large scale structure of the cosmos large scale structure of the universe. The Great Wall astronomy Great Wall , a vast conglomeration of galaxies over 500 million light years wide, provides a dramatic example of a large scale structure that redshift surveys can detect. The first redshift survey was the CfA Redshift Survey , started in 1977 with the initial data collection completed in 1982. The most notable, recent and low redshift surveys are the 2dF Galaxy Redshift Survey , Sloan Digital Sky Survey and the Galaxy And Mass Assembly survey . At high redshift there exist the DEEP2 Redshift Survey and the VIMOS VLT Deep Survey VVDS . Because of the demands on observing time required to obtain spectroscopic redshifts i.e., true redshifts measured by velocity , it has become commonplace to use photometric redshift s, http astrowww.phys.uvic.ca grads gwyn pz index.html based on brightness. Such redshifts can be used in surveys and to find the space distribution of galaxies, provided the galaxy types are well known, but, obviously they cannot be used to define points on the Hubble curve, because of circular reasoning.

  1. Survey article

    Unreferenced date May 2007 In academia , a survey article is a paper that is a work of synthesis, published through the usual channels a learned journal or collective volume, such as conference proceedings or collection of essays . It stands outside the usual run of academic journal research paper s, for two reasons it is not presented as the author s original research, but as a survey or summary of a field and it is not necessarily subject to the same degree of peer review . Sometimes short survey articles appear in the guise of book reviews, where the context of the book is summarised first, often at greater length than is devoted to the book. In a survey article, the treatment of the subject is often less detailed or in depth than would be acceptable in a textbook, and the topic may be one in which recent work requires summary. In its objectivity, a survey article may lie somewhere between a personal essay, and an encyclopedia article. The intention is to give rapid access to material scattered over many papers. Some fields, such as theoretical physics , depend very much on such surveys to bring recent progress into focus, on a time scale of around 18 months to two years.

It can also refer to the chart or map made by analysing a region from the air. This is typically done using aeroplanes , helicopters , UAV s such as the InView Unmanned Aircraft System and in history with Balloon aircraft balloons . Aerial survey should be distinguished by satellite imagery technologies because of its better resolution, quality and atmospheric conditions. Today, aerial survey is often recognized as a synonym for aerophotogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods. Aerial surveys can provide information on many things not visible from the ground.
