MapServer
MapServer is an open-source development environment for building spatially enabled internet applications, built in the C language, and is widely known as one of the fastest Web mapping engines available. It can run as a CGI program or via MapScript which supports several programming languages (using SWIG). MapServer can access hundreds of data formats, any raster or vector format supported by GDAL, and reprojections on-the-fly are handled by PROJ. MapServer was originally developed by Steve Lime, then working at the University of Minnesota — so, it was previously referred to as "''UMN MapServer''", to distinguish it from commercial "map servers"; today it is commonly referred to as just "MapServer", and is maintained by the MapServer Project Steering Committee (PSC). MapServer was originally developed with support from NASA, which needed a way to make its satellite imagery available to the public.

GDAL
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It may also be built with a variety of useful command line interface utilities for data translation and processing. Projections and transformations are supported by the PROJ library. The related ''OGR'' library (OGR Simple Features Library), which is part of the GDAL source tree, provides a similar ability for simple features vector graphics data. GDAL was developed mainly by Frank Warmerdam until the release of version 1.3.2, when maintenance was officially transferred to the GDAL/OGR Project Management Committee under the Open Source Geospatial Foundation. GDAL/OGR is considered a major free ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Mapping
Web mapping or an online mapping is the process of using maps, usually created through geographic information systems (GIS), on the Internet, more specifically in the World Wide Web (WWW). A web map or an online map is both served and consumed, thus web mapping is more than just web cartography, it is a service by which consumers may choose what the map will show. 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. Questions of quality, usability, social ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of GIS Software
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 GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures."GIS Software - A description in 1000 words" S. Steiniger and R. Weibel History The earliest geographic information systems, such as the |
