    Predefinito Map Server Freeware


    E' uno degli ambienti di sviluppo di riferimento per realizzare applicazioni gis basate su piattaforma web. In realtà non è un sistema Gis completo e non aspira a diventarlo, ma eccelle nella restituzione di dati spaziali (mappe, immagini, dati vettoriali) per il web.

    Beyond browsing GIS data, MapServer allows you create "geographic image maps", that is, maps that can direct users to content. For example, the Minnesota DNR Recreation Compass provides users with more than 10,000 web pages, reports and maps via a single application. The same application serves as a "map engine" for other portions of the
    site, providing spatial context where needed.
    MapServer was originally developed by the University of Minnesota (UMN) ForNet project in cooperation with NASA and the Minnesota Department of Natural Resources (MNDNR).
    Presently, the MapServer project is hosted by the TerraSIP project, a NASA sponsored project between the UMN and consortium of land management interests.
    The software is maintained by a growing number of developers (nearing 20) from around the world and is supported by a diverse group of organizations that fund enhancements and maintenance.

    MapGuide Open Source

    MapGuide Open Source è una piattaforma per le applicazioni di web mapping e per i servizi web geospaziali.

    Interactive Map Viewing
    Offers an AJAX Viewer (pure DHTML no plug-in required) or a vector-based DWF Viewer (requires an ActiveX Control) with a common user interface and JavaScript API
    AJAX Viewer offers a tiled map display for smooth navigation
    Allows feature selection by point, rectangle, radius, or polygon with immediate feedback
    Displays feature properties in multi-line tool tips
    Displays properties of the selected feature in a property browser panel
    Supports feature buffering, querying features that fall within selected polygons, and a tool for measuring distance
    Provides printing and plotting support

    Quality Cartographic Output
    Scale-dependent detail
    Rule-driven thematic layer stylization
    Dynamic labeling with overpost detection, labels that follow the path of a line, and automatic label resizing
    Anti-aliased image rendering
    True color support
    TrueType font support

    Built-in Resource Database for Manageability
    Provides hierarchical storage of XML resource documents that define maps, layers, data connections, symbology, and viewer layout
    Allows you to define data sources and layers once and then reference them from multiple maps
    Provides an access-based security model with inheritable permissions
    Permits metadata and binary data to be associated with resource documents

    Uniform Data Access
    Exclusive use of the Feature Data Objects (FDO) API for vector and raster feature data access
    Support for ESRI SHP and SDF vector file formats
    Support for ESRI ArcSDE, MySQL, ODBC database formats
    Support for Raster file formats via GDAL
    Support for OGC WMS and WFS
    Exclusive use of DWF for CAD-based data access

    Flexible Application Development
    Write your application logic once within the web server environment and it will work with either viewer on any client
    Develop your applications in PHP, .NET, or Java

    Extensive Server-Side APIs
    Create, query, read, and write permanent and session based XML resource documents
    Query and update feature data across all supported data sources, including spatial and attribute data, and schema discovery
    Perform coordinate reprojection and great circle distance computation
    Create, manipulate, and analyze geometry with support for spatial predicates based on the DE-9IM model, overlay functions (intersection, union, difference, symmetric difference), buffer, convex hull, area, and distance functions
    Produce stylized vector and raster maps and legends
    Manipulate runtime maps and layers, add / remove / change layers, change layer and group visibility, modify the definition of a layer, and alter the current view

    Fast, Scalable, Secure Server Platform
    Fully multi-threaded and takes advantage of multi-core / multi-processor technology
    Multiple servers can be configured as one logical site to improve scalability
    FastCGI based Map Agent loads once and stays loaded for use with both Apache and Microsoft IIS
    Database connections are pooled and shared between users, improving performance
    Tile caching ensures map image tiles are only rendered once for the AJAX Viewer no matter how many users are viewing the map
    Connection-oriented, role-based security
    Configurable logging of client access, administrative access, authentication attempts, errors, session lifetimes, and request tracing
    Web-based site administration allows remote site and server configuration, and log file access

    Multiple Platform Support
    Deploy on Microsoft Windows or Linux
    Serve applications with Apache or Microsoft IIS
    Browse applications with Microsoft Internet Explorer, Mozilla Firefox, and Safari
