    • Web Mapping & The Power of Where Lisa Arnold lisaarn@gmail.com Twitter @lisaarn
    • About MeGIS Analyst – Natural Heritage New Mexico,Museum of Southwestern Biology, University ofNew MexicoAdjunct Instructor – Department of Geography,University of New Mexico Geographic information Spatial modeling science Web mapping Conservation GIS GPS

    • Geographic Information SystemGIS is a computer-based technology tocollect, integrate,analyze, query, modeland visualizegeographic-orienteddata (like a visualdatabase) Technology, Methodology, Profession, Business Bolstad, P. (2008).
    • Answer Global and Local Questions Location – What is at …? – What exists at a particular location? Condition – Where is it? – Find location where certain conditions are satisfied. Trends – What has changed since? – Differences in an area over time. Patterns – What spatial patterns exist? – Spatial relationships between geographic data. Modeling – What if …? – Predict cause and effects of new scenarios. Great examples of GIS in action here!
    • GIS SoftwareDesktop Professional Industry– ArcGIS, ArcView – ESRI Leader– Geomedia – Intergraph Corp. •Environmental Systems– MapInfo – MapInfo Corp. Research Institute, Inc.– AutoCAD Map – AutoDesk Inc. •Founded in 1969– Smallworld - GE •Used by 24,000 state– Idrisi – Clark Labs and local governments– MapPoint - Microsoft •Annual revenues of– QGIS – open source $794 million •20% of revenues– GRASS – open source invested in Research &Server Development each year– ArcGIS Server - ESRI– MapServer – open source
    • Geospatial Revolutionhttp://geospatialrevolution.psu.edu/episode2/chapter3 Don’t miss these videos!
    • Web GIS Models Fu, P. & Sun, J. (2011).
    • Web GIS Architecture Fu, P. & Sun, J. (2011).
    • Application ComponentsBasemap– Often cached services pre-created by server Road map Aerial imageryOperational layers– Dynamic data rendered by the browser Real time weather Disease locationsTools– Find an address– Get directions– Query or search
    • Geospatial Web ServicesApplication components are driven bygeospatial web services– Web service is a method of communication– Programming interface that can be accessed by other applications
    • Fu, P. & Sun, J. (2011).
    • Service FunctionsMap services– Most basic: display, query, identifyData services– Edit, serve imagery, synchronizeAnalytical services– Geocode, route, proximity, buffer,– Geoprocessing – custom analysis models
    • Service StandardsOpen Geospatial Consortium– WMS (Web Map Service)– WFS (Web Feature Service)– WCS (Web Coverage Service )Other related standards– KML (Keyhole Markup Language)– GEORSS– GML (Geography Markup Language)
    • REST Services“With REST, everything is a URL”– Communication type used between the web service and the browser (client) Using the ArcGIS Server Rest API to generate a map covering the United States, asking the return to be a JPEG of 800 pixels by 500 pixels, the request is the following: http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_ShadedReli ef_World_2D/MapServer/export? bbox=-183.33, 15.20, -9.53, 74.08 &size=800, 500 &format=jpg &dpi=96 &f=image Fu, P. & Sun, J. (2011).
    • The MashupBringing it all together– Integrate diverse resources to create an applicationUse browser side API to represent webservices and handle user interaction– API for JavaScript– API for Flex– API for Silverlight
    • ArcGIS Viewer for Flex
    • Demo: site process
    • Start right now!ArcGIS.com– Search for geospatial web services– Create and share a mashup without programmingESRI’s Mapping for Everyone Site– Create and share maps– http://www.esri.com/mapping-for- everyone/index.html
