A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes
The PDF format is widely accepted and is considered the de facto standard for printable documents on the web. This means that users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard . [ 3 ]
It was created by Keyhole, Inc, which was acquired by Google in 2004. KML became an international standard of the Open Geospatial Consortium in 2008. [1] [2] Google Earth was the first program able to view and graphically edit KML files, but KML support is now available in many GIS software applications, such as Marble, [3] QGIS, [4] and ArcGIS ...

GIS data acquisition includes several methods for gathering spatial data into a GIS database, which can be grouped into three categories: primary data capture, the direct measurement phenomena in the field (e.g., remote sensing, the global positioning system); secondary data capture, the extraction of information from existing sources that are ...
In the same aspect, Google, one of the pioneers in web-based GIS, has developed its own language, which also uses an XML structure. Keyhole Markup Language (KML) is a file format used to display geographic data in an earth browser, such as Google Earth, Google Maps, and Google Maps for mobile browsers "Google KML definition"
Know the coordinates of the area you want to map—although you do have the option of visually selecting the area on the download page. Find the associated GIS files (also called tiles). SRTM files have names such as "N22E112.hgt.zip", standing for 22⁰ North, 112⁰ East. Download them. A small island will be made of a few files, the Korean ...
GeoServer additionally supports efficient publishing of geospatial data to Google Earth through the use of network links, using KML. Advanced features for Google Earth output include templates for customized pop-ups, time and height visualizations, and "super-overlays". GeoServer relies on GeoTools, a GIS library. [6]
