  • This will outline my exposure to GIS technology from school to today’s job. This will be done through a timeline analogy but will also show how the technologies in the end all flow together.
  • My GIS Timeline

    1. 1. My GIS Timeline Jeff Hobbs, GIS Coordinator San Jose Water Company [email_address] June 18, 2008
    2. 2. Wikipedia Reads… <ul><li>Wikipedia (and what I conceptually learned in school) defines GIS as </li></ul><ul><li>“… any system for capturing, storing, analyzing, managing and presenting data and associated attributes which are spatially referenced to Earth.” </li></ul><ul><li>“ In the strictest sense, it is any information system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically referenced information. In a more generic sense, GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, edit data, maps, and present the results of all these operations.” </li></ul>
    3. 3. When I was in School <ul><li>9 years ago (at SJSU), I defined GIS as (ESRI) software </li></ul><ul><ul><li>ArcView 3.x </li></ul></ul><ul><ul><li>ArcInfo command line </li></ul></ul>
    4. 4. The Other Players <ul><li>Once my first job came, I found out…there are more players in the game </li></ul><ul><ul><li>Intergraph GeoMedia </li></ul></ul><ul><ul><li>Intergraph MGE </li></ul></ul><ul><ul><li>MapInfo </li></ul></ul><ul><ul><li>Manifold </li></ul></ul>
    5. 5. Costs <ul><li>What’s the most expensive cost of any GIS? </li></ul>The Data
    6. 6. Access <ul><li>What do very few people typically have access to in a company/agency? </li></ul>The Data
    7. 7. The Internet Map Server <ul><li>The next jump in my GIS timeline was the internet map server </li></ul><ul><ul><li>ArcIMS (ArcGIS Server) </li></ul></ul><ul><ul><li>GeoMedia WebMap </li></ul></ul><ul><ul><li>MapGuide </li></ul></ul><ul><ul><li>UMN Map Server </li></ul></ul><ul><ul><li>Others </li></ul></ul>
    8. 8. The Internet Map Server <ul><li>Exposed the data that cost so much to many more people </li></ul>
    9. 9. Let’s Put it All on the Web Site <ul><li>Soon we began seeing many sites with GIS data </li></ul><ul><li>The initial dream…let’s put an entire GIS on the web! </li></ul>
    10. 10. Let’s Put it All on the Web Site <ul><li>Let’s take everything and put it into the browser </li></ul>
    11. 11. Way Too Hard to Use <ul><li>Great…the functionality was accessible by many. But who wanted to (or could) use it? </li></ul>
    12. 12. Meanwhile…In the Database World <ul><li>Around the same time internet map servers began gaining popularity, so did GIS-enabled databases </li></ul><ul><ul><li>Intergraph brought the first main stream geometry-enabled database software to market </li></ul></ul><ul><ul><ul><li>Store the graphic with the attributes </li></ul></ul></ul><ul><ul><li>ESRI “marketing machine” coined the term “geodatabase” </li></ul></ul>
    13. 13. Microsoft Access <ul><li>Microsoft Access became the de facto geodatabase (primarily out of popularity and ease of use) </li></ul><ul><ul><li>Intergraph called it an “Access Warehouse” </li></ul></ul><ul><ul><li>ESRI called it a “personal geodatabase” </li></ul></ul>
    14. 14. Enterprise Databases <ul><li>Next in the GIS timeline…enterprise databases </li></ul><ul><ul><li>All of the power of an enterprise database…but it can be used in a GIS environment </li></ul></ul><ul><ul><ul><li>Multi-user, users, transactions, views, replication, etc. </li></ul></ul></ul><ul><ul><li>Spatial processing! </li></ul></ul>
    15. 15. SELECT MSLINK, SDO_GEOM.SDO_AREA(GDO_GEOMETRY, 0.005,'unit=SQ_FT') AS &quot;AREA IN SQUARE FEET&quot; FROM PARCEL WHERE MSLINK = 7607; Spatial Query Using SQL SELECT C.CITY_NAME FROM USSAMPLE.CITIES C, USSAMPLE.STATES S WHERE S.STATE_NAME = 'CALIFORNIA' AND C.CITY_NAME LIKE 'M%' AND SDO_RELATE(S.GEOMETRY, C.GEOMETRY, 'MASK=CONTAINS') = 'TRUE' ORDER BY C.CITY_NAME;
    16. 16. Spatial Processing in the Database <ul><li>OK, I know I can do it, but why would I want to? It sure looks harder than GeoMedia. </li></ul><ul><ul><li>Automation </li></ul></ul><ul><ul><li>Many times that GIS interface really isn’t needed </li></ul></ul><ul><ul><ul><li>City of San Jose eMap Application </li></ul></ul></ul>
    17. 17. Web Mapping 2.0/GeoWeb <ul><li>Next on the timeline…“GeoWeb” </li></ul><ul><ul><li>Web 2.0 ease of use </li></ul></ul><ul><ul><li>Rich Internet Applications (RIAs) </li></ul></ul><ul><ul><li>Web Services </li></ul></ul><ul><ul><li>Standards </li></ul></ul><ul><ul><li>Acronym soup </li></ul></ul>SOAP WSDL WMS WFS OGC WFS-T GML KML XML REST AJAX SVG SWF XAML
    18. 18. Web Mapping 2.0/GeoWeb <ul><li>Intuitive </li></ul><ul><li>Fast </li></ul><ul><li>Massive amounts of data </li></ul><ul><li>Open </li></ul><ul><li>Free* </li></ul><ul><li>In other words… </li></ul>
    19. 19. Mashups <ul><li>OK…I’ve got tons of business data and I want it mapped. What do I do? </li></ul><ul><ul><li>In this past this would be an internet map server based solution </li></ul></ul>
    20. 20. Mashups <ul><li>Not anymore! Now we think Google, Yahoo, and Microsoft… </li></ul><ul><li>http://www.housingmaps.com/ - Google Maps with Craig’s List data </li></ul><ul><li>EveryBlock – Chicago – Google data and many other sources </li></ul><ul><li>California School Finder – Microsoft Virtual Earth and school location data </li></ul>
    21. 21. Tying the Geodatabase into the Mashup <ul><li>Now let’s tie the enterprise geodatabase into the mix </li></ul><ul><li>Boston Redevelopment Authority – Development Projects </li></ul><ul><li>City of San Jose Locator Site </li></ul>
    22. 22. Let’s not Forget Google Earth! <ul><li>Fast access to tons of data </li></ul><ul><ul><li>The world is at your finger tips! </li></ul></ul><ul><li>Easy to use </li></ul><ul><li>Cool to watch </li></ul><ul><li>Provides a lot of valuable data </li></ul><ul><li>Easy to integrate! </li></ul><ul><li>Free* </li></ul>
    23. 23. Open Source Software <ul><li>Last stop on the timeline…open source software </li></ul><ul><ul><li>In many ways this has been driven through the free APIs provided by the big three </li></ul></ul><ul><ul><li>Becoming much more widely accepted </li></ul></ul><ul><ul><li>Free (usually) </li></ul></ul><ul><ul><li>Have become much more mature </li></ul></ul>
    24. 24. Open Source Client Software <ul><li>Take at look at the OSGeo web site </li></ul><ul><ul><li>GRASS GIS </li></ul></ul><ul><ul><li>Quantum GIS </li></ul></ul><ul><ul><li>uDig </li></ul></ul><ul><ul><li>GeoSetter+ </li></ul></ul><ul><ul><li>gvSIG </li></ul></ul><ul><ul><li>MapWindow GIS </li></ul></ul><ul><ul><li>Many More! </li></ul></ul>
    25. 25. Open Source Server Software <ul><li>MapServer </li></ul><ul><li>OpenLayers+ </li></ul><ul><li>MapGuide Open Source </li></ul><ul><li>MapBuilder </li></ul><ul><li>Mapbender </li></ul><ul><li>Many More! </li></ul>
    26. 26. Open Source Database Software <ul><li>PostGIS (PostgreSQL) </li></ul><ul><li>MySQL </li></ul>
    27. 27. Closing Thoughts <ul><li>Main stream </li></ul><ul><li>Enabling technology </li></ul><ul><li>GIS <> Buzzword anymore </li></ul><ul><li>Good times ahead </li></ul>
