XYZ Tiles coordinate numbers. Properties of tiled web maps that require convention or standards include the size of tiles, the numbering of zoom levels, the projection to use, the way individual tiles are numbered or otherwise identified, and the method for requesting them.
Web GIS has numerous functions, which can be divided into categories of Geospatial web services, including web feature services, web processing services, and web mapping services. [3] Geospatial web services are distinct software packages available on the World Wide Web that can be employed to perform a function with spatial data.
A web map app in a smart phone of Lake Lappajärvi in Finland. Web mapping or an online mapping is the process of using, creating, and distributing maps on the World Wide Web (the Web), usually through the use of Web geographic information systems (Web GIS).
The Web Server Gateway Interface (WSGI, pronounced whiskey [1] [2] or WIZ-ghee [3]) is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python programming language. The current version of WSGI, version 1.0.1, is specified in Python Enhancement Proposal (PEP) 3333. [4]
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important.
The World Wide Web is an information system that uses the internet to host, share, and distribute documents, images, and other data. [33] Web GIS involves using the World Wide Web to facilitate GIS tasks traditionally done on a desktop computer, as well as enabling the sharing of maps and spatial data. [7]
Specifics: Example of Earth's cloud coverage layer(s), whole planet, projection ?, datum ?. Files: uncompressed file 34Mb, whole Earth, 1 tiles. —' ♣ Comment(s): Not a GeoTIF, and thus, not georeferenced, but can be a powerful tool to add realistic clouds to other planets than Earth, as explained in this Mars example ..
Example of hardware for mapping (GPS and laser rangefinder) and data collection (rugged computer). The current trend for geographical information system (GIS) is that accurate mapping and data analysis are completed while in the field. Depicted hardware (field-map technology) is used mainly for forest inventories, monitoring and mapping.
