Spatialite
SpatiaLite is a spatial extension to SQLite, providing vector geodatabase functionality. It is similar to PostGIS, Oracle Spatial, and SQL Server with spatial extensions, although SQLite/SpatiaLite aren't based on client-server architecture: they adopt a simpler personal architecture. i.e. the whole SQL engine is directly embedded within the application itself: a complete database simply is an ordinary file which can be freely copied and transferred from one computer/OS to a different one without any special precaution. SpatiaLite extends SQLite's existing spatial support to cover the OGC's SFS specification. It isn't necessary to use SpatiaLite to manage spatial data in SQLite, which has its own implementation of R-tree indexes and geometry types. But SpatiaLite is needed for advanced spatial queries and to support multiple map projections. SpatiaLite is provided natively for Linux and Windows as a software library as well several utilities that incorporate the SpatiaLite lib ...

Web2py (web Framework)
Web2py is an open-source web application framework written in the Python programming language. Web2py allows web developers to program dynamic web content using Python. Web2py is designed to help reduce tedious web development tasks, such as developing web forms from scratch, although a web developer may build a form from scratch if required. Web2py was originally designed as a teaching tool with emphasis on ease of use and deployment. Therefore, it does not have any project-level configuration files. The design of web2py was inspired by the Ruby on Rails and Django frameworks. Like these frameworks, web2py focuses on rapid development, favors convention over configuration approach and follows a model–view–controller (MVC) architectural pattern. Overview Web2py is a full-stack framework in that it has built-in components for all major functions, including: * HTTP requests, HTTP responses, cookies, sessions; * multiple protocols HTML/XML, REST, ATOM and RSS, RTF and CS ...

ArcGIS
ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri. ArcGIS was first released in 1982 as ARC/INFO, a command line-based GIS. ARC/INFO was later merged into ArcGIS Desktop, which was eventually superseded by ArcGIS Pro in 2015. Additionally, ArcGIS Server is a server-side GIS and geodata sharing software. Product history Prior to the ArcGIS suite, Esri had focused its software development on the command line Arc/INFO workstation program and several graphical user interface-based products such as the ArcView GIS 3.x desktop program. Other Esri products included MapObjects, a programming library for developers, and ArcSDE as a relational database management system. The various products had branched out into multiple source trees and did not integrate well with one another. In January 1997, Esri decided to revamp its GIS software platform, creating a single integrated software architecture. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Database Connectivity
Java Database Connectivity (JDBC) is an application programming interface (API) for the Java programming language which defines how a client may access a database. It is a Java-based data access technology used for Java database connectivity. It is part of the Java Standard Edition platform, from Oracle Corporation. It provides methods to query and update data in a database, and is oriented toward relational databases. A JDBC-to-ODBC bridge enables connections to any ODBC-accessible data source in the Java virtual machine (JVM) host environment. History and implementation Sun Microsystems released JDBC as part of Java Development Kit (JDK) 1.1 on February 19, 1997. Since then it has been part of the Java Platform, Standard Edition (Java SE).

Geospatial Data Abstraction Library
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.

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.

Web Feature Service
In computing, the Open Geospatial Consortium Web Feature Service (WFS) Interface Standard provides an interface allowing requests for geographical features across the web using platform-independent calls. One can think of geographical features as the "source code" behind a map, whereas the WMS interface or online tiled mapping portals like Google Maps return only an image, which end-users cannot edit or spatially analyze. The XML-based Geography Markup Language (GML) furnishes the default payload-encoding for transporting geographic features, but other formats like shapefiles can also serve for transport. In early 2006 the OGC members approved the OpenGIS GML Simple Features Profile. This profile is designed both to increase interoperability between WFS servers and to improve the ease of implementation of the WFS standard. The OGC membership defined and maintains the WFS specification. Numerous commercial and open-source implementations of the WFS interface standard exist, i ...
