  3. Image rectification - Wikipedia

    en.wikipedia.org/wiki/Image_rectification

    Image rectification in GIS converts images to a standard map coordinate system. This is done by matching ground control points (GCP) in the mapping system to points in the image. These GCPs calculate necessary image transforms. [11] Primary difficulties in the process occur when the accuracy of the map points are not well known

    The app, in its current function, however, seems to give only geotagged photo results. As of 2017, the Wikipedia-World Project provides a simple map search tool which can display tagged articles near to a particular location, as well as a variety of more sophisticated tools integrated with external mapping services.

    Image registration or image alignment algorithms can be classified into intensity-based and feature-based. [3] One of the images is referred to as the moving or source and the others are referred to as the target, fixed or sensed images. Image registration involves spatially transforming the source/moving image(s) to align with the target image.

  7. Web Map Service - Wikipedia

    en.wikipedia.org/wiki/Web_Map_Service

    A Web Map Service (WMS) is a standard protocol developed by the Open Geospatial Consortium in 1999 for serving georeferenced map images over the Internet. [1] These images are typically produced by a map server from data provided by a GIS database.

  8. Bitmap - Wikipedia

    en.wikipedia.org/wiki/Bitmap

    A GIF is an example of a graphics image file that uses a bitmap. [2] As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each pixel may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the ...
