Collaborative mapping is the aggregation of Web mapping web maps and user generated content , from a group of individuals or entities, and can take several distinct forms. With the growth of technology for storing and sharing maps, collaborative maps have become competitors to commercial services, in the case of OpenStreetMap , or components of them, as in Google Map Maker . Types Collaborative Mapping applications vary depending on which feature the collaborative edition takes place on the map itself shared surface , or on overlays to the map. A very simple collaborative mapping application would just plot users locations Social mapping or geosocial networking or Wikipedia articles locations Placeopedia . Collaborative implies the possibility of edition by several distinct individuals so the term would tend to exclude applications such as wayfaring where the maps are not meant for the general user to modify. In this kind of application, the map itself is created collaboratively by sharing a common surface. For example WikiMapia adds user generated place names and descriptions to locations. Collaborative mapping and specifically surface sharing faces the same problems as revision control , namely concurrent access issues and versioning. In addition to these problems, collaborative maps must deal with the difficult issue of cluttering, due to the geometric constraints inherent in the media. One approach to this problem is using overlays. Overlays group together items on a map, allowing ....

Orphan date February 2009 Prospectivity mapping , also known as mineral prospectivity mapping or mineral potential mapping, defines a process used to make better use of mineral exploration data. Geological and geophysical datasets, such as geologic map lithological , structural and topographical maps, aeromagnetic, Earth s gravity gravity and radiometric imagery are the typical datasets used in the construction of prospectivity maps. There are two main approaches to prospectivity mapping data driven and knowledge driven. In areas with significant known mineralisation, a data driven approach can be adopted in which known deposits are analysed in relation to the surrounding geology. A number of parametric and non parametric statistical tests can be used to determine if identified spatial relationships are considered statistically significant. Important relationships are then spatially quantified over the entire region of interest. Ultimately multiple quantified relationships are combined, typically using a geographic information system GIS into a single prospectivity map. In areas with little known mineralisation, a knowledge driven approach can be implemented in which a mineral systems approach is used in which theories about the formation of the deposit are identified, spatially quantified and then combined using a GIS. Prospectivity mapping can be constructed using a mix of data driven and knowledge driven components and these are often referred to as hybrid prospectivity maps.

Multiple issues orphan January 2012 context December 2011 unreferenced December 2011 Visual mapping is a formalized movement, a branch off from projectioning of the visual and motion art form of VJing . The term mapping is closely associated for visual projection on surfaces and to the use of spatial and structural visualization most popularized on side of the buildings. The live video performance, i.e. Vjing are done on the surface of spatial structure with video projectors. Mapping require special software created for visual artist and vjing the proprietary company like madmapper by Modul8 and Resolume 4 can be use to do visual mapping, without a media server . History Video Projection Mapping is an exciting new projection technique that can turn almost any surface into a dynamic video display. Specialized software is used to warp and mask the projected image to make it fit perfectly on irregularly shaped screens. When done right, the end result is a dynamic projection installation that transcends ordinary video projection.

Also, cube mapping provides a much larger capacity to support real time rendering of reflections relative to sphere mapping because the combination of inefficiency and viewpoint dependency severely limit the ability of sphere mapping to be applied when there is a consistently changing viewpoint.

In computer graphics , sphere mapping or spherical environment mapping is a type of reflection mapping that approximates reflective surfaces by considering the environment to be an infinitely far away spherical wall. This environment is stored as a texture depicting what a mirrored sphere would look like if it were placed into the environment, using an orthographic projection as opposed to one with perspective graphical perspective . This texture contains reflective data for the entire environment, except for the spot directly behind the sphere. For one example of such an object, see Escher s drawing Hand with Reflecting Sphere . To use this data, the surface normal of the object, view direction from the object to the camera, and or reflected direction from the object to the environment is used to calculate a texture coordinate to look up in the aforementioned texture map. The result appears like the environment is reflected in the surface of the object that is being rendered. Usage example In the simplest case for generating texture coordinates, suppose The map has been created as above, looking at the sphere along the z axis. The texture coordinate of the center of the map is 0,0 , and the sphere s image has radius 1. We are rendering an image in the same exact situation as the sphere, but the sphere has been replaced with a reflective object. The image being created is orthographic, or the viewer is infinitely far away, so that the view direction does not change as one moves across the image. At texture coordinate math x,y math , note that the depicted location on the sphere is math x,y,z math where z is math sqrt 1 x 2 y 2 math , and the normal at that location is also math x,y,z math .

In computer graphics , it is most commonly a math mathbb R 2 math to math mathbb R 3 math map, suitable for Texture mapping converting a 2D image a wikt texture texture to a three dimensional object of a given topology . UVW , like the standard Cartesian coordinate system , has three dimensions the third dimension allows texture maps to wrap in complex ways onto irregular surfaces. Each point in a UVW map corresponds to a point on the surface of the object. The graphic designer or programmer generates the specific mathematical function to implement the map, so that points on the texture are assigned to XYZ points on the target surface. Generally speaking, the more orderly the unwrapped polygons are, the easier it is for the texture artist to paint features onto the texture. Once the texture is finished, all that has to be done is to wrap the UVW map back onto the object, projecting the texture in a way that is far more flexible and advanced, preventing Artifact error graphic artifacts that accompany more simplistic texture mappings such as planar projection . For this reason, UVW mapping is commonly used to texture map non platonic solids , non geometric primitive s, and other irregularly shaped objects, such as Character computing characters and furniture .

A color mapping may be referred to as the algorithm that results in the mapping function or the algorithm that transforms the image colors. Color mapping is also sometimes called color transfer or, when Grayscale grayscale images are involved, brightness transfer function BTF . Algorithms There are two types of color mapping algorithms those that employ the statistics of the colors of two images, and those that rely on a given pixel correspondence between the images. An example of an algorithm that employs the statistical properties of the images is histogram matching . This is a classic algorithm for color mapping, suffering from the problem of sensitivity to image content differences. Newer statistic based algorithms deal with this problem.

Merge Genetic admixture date March 2010 Admixture mapping is a method of gene mapping that makes use of a population of mixed ancestry an admixed population to find the genetic loci that contribute to differences in diseases or other phenotypes found between the different ancestral populations. The method is best applied to populations with recent admixture from two populations that were previously genetically isolated for tens of thousands of years, such as African Americans admixture of African and European populations . The method attempts to correlate the degree of ancestry near a genetic locus with the phenotype or disease of interest. Genetic markers which differ in frequency between the ancestral populations are needed across the genome. ref name Shriver Shriver MD, Mark D, et al. 2003. Skin Pigmentation, biogeographical ancestry and admixture mapping. Hum. Genet. 112, 387 399 2003 ref Admixture mapping is based on the assumption that differences in disease rates or phenotypes are due in part to differences in the frequencies of disease causing or phenotype causing genetic variants between populations. In an admixed population, these causal variants will occur more frequently on chromosomal segments inherited from one or another ancestral population. The first admixture scans were published in 2005 and since then genetic contributors to a variety of disease and trait differences have been mapped. ref cite doi 10.1146 annurev genom 082509 141523 ref These include hypertension , multiple sclerosis , Body mass index BMI , and prostate cancer in African Americans.

In mathematics , a contraction mapping , or contraction , on a metric space M,d is a function mathematics function f from M to itself, with the property that there is some nonnegative real number math k 1 math such that for all x and y in M , math d f x ,f y leq k ,d x,y . math The smallest such value of k is called the Lipschitz constant of f . Contractive maps are sometimes called Lipschitzian maps . If the above condition is instead satisfied for k 1, then the mapping is said to be a non expansive map . More generally, the idea of a contractive mapping can be defined for maps between metric spaces. Thus, if M , d and N , d are two metric spaces, and math f M mapsto N math , then there is a constant k such that math d f x ,f y leq k ,d x,y math for all x and y in M . Every contraction mapping is Lipschitz continuous and hence uniformly continuous for a Lipschitz continuous function, the constant k is no longer necessarily less than 1 . A contraction mapping has at most one fixed point mathematics fixed point . Moreover, the Banach fixed point theorem states that every contraction mapping on a nonempty completeness topology complete metric space has a unique fixed point, and that for any x in M the iterated function sequence x , f x , f f x , f f f x , ... converges to the fixed point.

The technique is used to measure the size of the broad emission line region and mass of the alleged central black hole in Active galactic nucleus active galactic nuclei . ref B.M. Peterson & K. Horne http arxiv.org abs astro ph 0407538 Reverberation Mapping of Active Galactic Nuclei 2004 ref Direct Doppler effect Doppler measures of water Astrophysical maser masers surrounding the galactic nucleus nucleus of nearby galaxies have revealed a very fast Kepler s laws of planetary motion Keplerian motion , only possible with a high concentration of matter in the center. Currently, the only known objects that can pack enough matter in such a small space are black holes, or things that will evolve into black holes within astrophysically short timescales. For active galaxy active galaxies farther away, the width of broad spectral lines can be used to probe the gas orbiting near the event horizon . The technique of reverberation mapping uses variability of these lines to measure the mass , and perhaps the rotation spin of the presumed supermassive black hole that powers the active galaxy s engine . Only a small handful of AGN less than 40 have been accurately mapped. One of the most luminous objects with reverberation mapping results, and one of the only named AGN, is Kate s Quasar .

In computer graphics , photon mapping is a two pass global illumination algorithm developed by Henrik Wann Jensen that solves the rendering equation . Ray tracing graphics Rays from the light source and rays from the camera are traced independently until some termination criterion is met, then they are connected in a second step to produce a radiance value. It is used to realistically simulate the interaction of light with different objects. Specifically, it is capable of simulating the refraction of light through a transparent substance such as glass or water, diffuse interreflection between illuminated ... path tracing bidirectional path tracing and Metropolis light transport , photon mapping is a biased ... thumb A model of a wine glass ray tracing ray traced with photon mapping to show Caustic optics ... are visible on the table.
