Web mapping
Web mapping is the process of using maps delivered by geographical information systems (GIS). Since a web map on the World Wide Web is both served and consumed, web mapping is more than just web cartography, it is both a service activity and consumer activity. Web GIS emphasizes geodata processing aspects more involved with design aspects such as data acquisition and server software architecture such as data storage and algorithms, than it does the end-user reports themselves.〔 The terms ''web GIS'' and ''web mapping ''remain somewhat synonymous. Web GIS uses web maps, and end users who are ''web mapping'' are gaining analytical capabilities. The term ''location-based services'' refers to ''web mapping'' consumer goods and services. Web mapping usually involves a web browser or other user agent capable of client-server interactions.〔
While web mapping today is still being developed, challenges and innovations involving the feedback of the quality, the usability, the social benefits, and the legal constraints, drive its evolution.
==Development and implementation==
The advent of web mapping can be regarded as a major new trend in cartography. Until recently cartography was restricted to a few , institutes and , requiring relatively expensive and complex hardware and software as well as skilled cartographers and geomatics engineers.
With the rise of web mapping, a range of data and technology was born - from free data generated by OpenStreetMap to proprietary datasets owned by Navteq, Google, Waze, and others. A range of free software to generate maps has also been conceived and implemented alongside proprietary tools like ArcGIS. As a result, the barrier to entry for serving maps on the web has been lowered.
