27 27  |The [[**shapefile**>>https://en.wikipedia.org/wiki/Shapefile]] format is a popular geospatial vector data format for geographic information system software. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other GIS software products. The shapefile format can spatially describe vector features: points, lines, and polygons, representing, for example, water wells, rivers, and lakes. Each item usually has attributes that describe it, such as name or temperature.

29 -In remote sensing, [[**spatial resolution**>>https://en.wikipedia.org/wiki/Image_resolution]] is typically limited by diffraction, as well as by aberrations, imperfect focus, and atmospheric distortion. The ground sample distance (GSD) of an image, the pixel spacing on the Earth's surface, is typically considerably smaller than the resolvable spot size.

37 37  |[[**TIF**>>https://file.org/extension/tif]] stands for Tagged Image File. These files are also known as TIFF files, or "Tagged Image File Format" files. The files that contain the .tif file extension contain high-quality graphic images. These files are used for storing raster graphics images, popular among graphic artists, the publishing industry and photographers. TIFF is widely supported by scanning, faxing, word processing, optical character recognition, image manipulation, desktop publishing, and page-layout applications.
