Embodiment Construction

[0043] background

[0044] First, some background technologies are described to help understand the present invention.

[0045] Potential field data includes, but is not limited to, gravimeter data, gravity gradiometer data, vector magnetometer data, and true magnetic gradiometer data. These data are characterized mathematically by governing a series of relationships of how these quantities vary across space, and how different types of measurements are related. The elements and representation of the potential field can be derived via scalars.

[0046] For gravity, the relevant potential energy is the gravitational scalar potential Φ(r), defined as

[0047] Φ ( r ) = ∫ ∫ ∫ Gρ ( r ′ ) | r - ...

Abstract

This invention relates to improved techniques for processing potential field measurement data from airborne surveys such as gravity surveys, and to improved techniques for data acquisition which are enabled by the improved data processing techniques. Described is a method of processing measured potential field data from a potential field survey of the earth to determine map data for mapping said field, the method comprising: inputting said measured potential field data, said measured potential field data comprising data defining a plurality of potential field measurements and associated positions, each said position defining a position of a said potential field measurement in three dimensions; determining a plurality relationships between said potential field measurements and said positions, each said relationship relating a said potential field measurement to a function of a said associated position in three dimensions multiplied by a field mapping parameter; and determining a substantially self-consistent set of said field mapping parameters for said plurality of relationships to thereby determine said map data.

Description

technical field [0001] The present invention relates to an improved technique for processing potential field measurement data from aerial surveys, such as gravity surveys, and to an improved technique for data acquisition by such improved data processing techniques. Background technique [0002] Traditionally, aerial potential field measurements such as gravimetric measurements are performed on grid patterns. A mesh is defined by an orthogonal collection of parallel lines (flight paths) on a 2D surface overlaid on the underlying terrain. The covered surface satisfies a minimum altitude constraint (defined by the minimum distance the aircraft is allowed to fly above the ground), and a constraint on the maximum rate at which the aircraft can climb / descent (typically about three percent). This approach suffices for flat terrain, but for hilly or mountainous terrain, where the surface the aircraft is flying on changes two or three kilometers from the bottom of the underlying va...
