Oracle Spatial and Graph supports a full range of geospatial data and analytics for land management and GIS, mobile location services, sales territory management, transportation, LiDAR analysis and location-enabled Business Intelligence. The graph features include RDF graphs for applications ranging from semantic data integration to social network analysis to linked open data and network graphs used in transportation, utilities, energy and telcos and drive-time analysis for sales and marketing applications.

NetLogo Home Page NetLogo is a multi-agent programmable modeling environment. It is used by tens of thousands of students, teachers and researchers worldwide. It also powers HubNet participatory simulations. It is authored by Uri Wilensky and developed at the CCL. uDig uDig has a walkthrough in Flash and also quick start directions for those who wish to complete a full version build to write plug-ins or contribute to the main build. uDig can use GRASS for complex vector operations and also embeds JGRASS and specialized hydrology tools from the Horton Machine. It supports shapefiles, PostGIS, WMS, and many other data sources natively. Web Map Service 1) Overview2) Downloads3) Official Schemas4) Related News 1) Overview The OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed.

Technical Collaboration What is GeoSciML GeoSciML is an XML–based data transfer standard for the exchange of digital geoscientific information. It accommodates the representation and description of features typically found on geological maps, as well as being extensible to other geoscience data such as drilling, sampling, and analytical data.

GIS Extension This extension adds GIS (Geographic Information Systems) support to NetLogo. It provides the ability to load vector GIS data (points, lines, and polygons), and raster GIS data (grids) into your model. The extension supports vector data in the form of ESRI shapefiles. The shapefile (.shp) format is the most common format for storing and exchanging vector GIS data. GeoSciML GeoSciML or Geoscience Markup Language is a GML Application Schema that can be used to transfer information about geology, with an emphasis on the "interpreted geology" that is conventionally portrayed on geologic maps. Its feature-type catalogue includes Geologic Unit, Mapped Feature, Earth Material, Geologic Structure, and specializations of these, as well as Borehole and other observational artefacts. It was created by, and is governed by, the Commission for the Management and Application of Geoscience Information (CGI) to support interoperability of information served from Geologic Surveys and other data custodians. It will be used in the OneGeology project, an effort to create a geological map of the entire Earth, served live by merging data from many national geological surveys. The GeoSciML project was initiated in 2003, under the auspices of the Commission for Geoscience Information (CGI) working group on Data Model Collaboration.

Development and Comparison of Open Source based Web GIS Frameworks on WAMP and Apache Tomcat Web Servers The generic layered architecture of Web GIS consists of three layers namely user interface layer, application layer and database layer. The clients access the system by interacting with the user interface layers that takes the input and shows the output of the system. It involves graphical user interface therefore it must be designed cautiously so that the user can understand it easily. The application layer provides the map visualization functions like panning, zooming etc.
