  1. Using a Mix of Technologies to Collect and Present Geographic Information on the Web (or desktop) Aleda Freeman MassGIS (Office of Geographic and Environmental Information) Executive Office of Energy and Environmental Affairs (EOEEA) http://maps.massgis.state.ma.us/temp/NEARC_webservices_09.ppt NEARC 2009 - Nashua, NH

  2. Short history of online mapping at MassGIS Examples of requests to web map services + responses Gallery of the wide variety of applications (and technologies) using the services 3 Parts NEARC 2009 - Nashua, NH

  3. Created in 1988 as the GIS office for the Executive Office of Environmental Affairs (EOEA) and its constituent agencies 1999 Legislation (MGL chap 21 sec 4B) established the “Office of Geographic and Environmental Information” in EOEA. Its mission is very broad: “Collect, consolidate store and provide geographic and environmentalinformation in order to improve stewardship of natural resources and the environment, promote economic development and guide land-use planning, risk assessment, emergency response and pollution control.” What Is MassGIS? NEARC 2009 - Nashua, NH

  4. PUBLIC SECTOR State agencies Regional planning agencies Cities and towns Colleges and Universities Federal agencies PRIVATE SECTOR Private non-profit organizations GIS consulting firms Engineering and surveying firms Colleges and Universities Utilities MassGIS Users NEARC 2009 - Nashua, NH

  5. Late 1990s: Use of ESRI ArcView Internet Map Server (discontinued) From late 1990s to today: Use of ESRI ArcIMS 1999: Mass.gov E-gov initiative spurs development of OGC WMS/WFS mapping service 2002: MassGIS offers OGC standard based WMS/WFS with custom software (MapAccess) (requests translated to ArcIMS XML) (discontinued) 2004: Installation of GeoServer (open source, reference implementation of OGC standards) Oracle with ESRI SDEis the common data storage for all these map servers History of Web Mapping Services at MassGIS NEARC 2009 - Nashua, NH

  6. ESRI ArcIMS GeoServer Current Online Mapping iPhone ESRI ArcMap Flash Gaia MapBuilder SDE with Oracle uDig OpenLayers Google Earth Google maps data storage map servers desktop browser types of applications NEARC 2009 - Nashua, NH

  7. WMS – Web Map Service (GetMap) Image of a map returned (PNG, TIFF, etc) Can get a legend graphic WFS – Web Feature Service (GetFeature) Feature info returned (attributes and/or coordinates) For WMS or WFS: Can filter on attributes or geometry Can get data back in > 3,000 projections Requests can be URL or XML Many output formats: JPG, PNG, GML, KML, SHP, PDF, XLS, CSV 2 Main Types of OGC Requests NEARC 2009 - Nashua, NH
