Pictometry
Pictometry is a patented aerial survey technique for producing oblique georeferenced imagery showing the fronts and sides of buildings and locations on the ground. Photos are captured by low-flying airplanes, depicting up to 12 perspectives (shot from a 40 degree angle) as well as an orthogonal (overhead) view of every location flown. These perspectives are then stitched together to create composite aerial maps that may span many miles of terrain. Because they are captured at an angle, the pixels in the resulting images are trapezoidal, rather than rectangular. This necessitates special software and algorithms to accurately determine objects’ size and position on the maps. Uses Pictometry imagery can be overlaid with various shapefiles and GIS information because every pixel is georeferenced to its exact location on the earth. This allows pictometry imagery to be integrated into many existing GIS software applications for use in many businesses, while creating a much richer dat ...

Aerial Survey
Aerial survey is a method of collecting geomatics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Typical types of data collected include aerial photography, Lidar, remote sensing (using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet) and also geophysical data (such as aeromagnetic surveys and gravity. It can also refer to the chart or map made by analysing a region from the air. Aerial survey should be distinguished from satellite imagery technologies because of its better resolution, quality and atmospheric conditions (which can negatively impact and obscure satellite observation). Today, aerial survey is sometimes 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 vis ...

Georeferencing
Georeferencing means that the internal coordinate system of a map or aerial photo image can be related to a geographic coordinate system. The relevant coordinate transforms are typically stored within the image file ( GeoPDF and GeoTIFF are examples), though there are many possible mechanisms for implementing georeferencing. The most visible effect of georeferencing is that display software can show ground coordinates (such as latitude/longitude or UTM coordinates) and also measure ground distances and areas. In other words, georeferencing means to associate a digital image file with locations in physical space. The term is commonly used in the geographic information systems field to describe the process of associating a physical map or raster image of a map with spatial locations. Georeferencing may be applied to any kind of object or structure that can be related to a geographical location, such as points of interest, roads, places, bridges, or buildings. Geographic loca ...

Orthogonal
In mathematics, orthogonality is the generalization of the geometric notion of ''perpendicularity''. By extension, orthogonality is also used to refer to the separation of specific features of a system. The term also has specialized meanings in other fields including art and chemistry. Etymology The word comes from the Ancient Greek ('), meaning "upright", and ('), meaning "angle". The Ancient Greek (') and Classical Latin ' originally denoted a rectangle. Later, they came to mean a right triangle. In the 12th century, the post-classical Latin word ''orthogonalis'' came to mean a right angle or something related to a right angle. Mathematics Physics * In optics, polarization states are said to be orthogonal when they propagate independently of each other, as in vertical and horizontal linear polarization or right- and left-handed circular polarization. * In special relativity, a time axis determined by a rapidity of motion is hyperbolic-orthogonal to a space axis of s ...

Pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Tax Assessment
Tax assessment, or assessment, is the job of determining the value, and sometimes determining the use, of property, usually to calculate a property tax. This is usually done by an office called the assessor or tax assessor. Governments need to collect taxes in order to function. Federal, state and local governments impose tax assessments against real property, personal property and income. The word tax assessment is used in different ways but often refers to a tax liability owed by a taxpayer. In the case of property, a tax assessment is an evaluation or an estimate of value that is typically performed by a tax assessor. The assessment leads to an “assessed value,” which is a base number used in the calculation of the property tax. There is a relationship between the assessed value and the tax liability. The higher the assessment, the higher the tax bill. In some jurisdictions, the assessed value is meant to equal the market value of property. In other areas, the market va ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...
