  8. • Largest estuary on the West Coast • Fed by

    Sacramento, San Joaquin, Mokelumne, Cosumnes, and Calaveras Rivers • 40% of California’s runoff passes through it • Environment radically altered over 160 years • How would you restore it? First you need to know what it looked like • Let users explore the evidence, learn about research process A Center of Controversy The Sacramento-San Joaquin Delta
  9. • Highly respected independent research and consulting organization • Working

    for four years on report to California Department of Fish and Game • Released report in September 2012 The San Francisco Estuary Institute Aquatic Science Center Making Sense of the Delta Historical Ecologists at Work Robin Grossinger and Alison Whipple, Delta Historical Ecology Project
  10. Historical Ecology Synthesizes diverse historical records to learn how habitats

    were distributed and ecological functions were maintained within the native California landscape. Understanding how streams, wetlands, and woodlands were organized along physical gradients helps scientists and managers develop new strategies for more integrated and functional landscape management
  11. Historical Documents and Accounts Figure 5.9. An 1851 sketch of

    the basin landscape pattern. Though the author of the letter and this map gets a few of the facts wrong (e.g., Cache Creek did not connect directly to Cache Slough), he does convey the character of the basin landscape. To describe the pattern and his map, George Browning (1851) states that the land near the river descends (the dark pencil hashes), ” then comes the Tola or Bull Rush [stipples]...and then comes the Lake or Pond [marked with ‘L’].” (Browning 1851, courtesy of The Bancroft Library, UC Berkeley)
  12. “Shortly after 1900, the USGS (established in 1879) began surveys

    in the Delta region that resulted in a rather unique 7.5 minute topographic quadrangles at a scale of 1:31,680 (use of this scale was discontinued in the 1950s). With contours spaced at 10 feet, this scale provides great detail of the early topography of the Delta.” USGS Topographic Quads Ca. 1909-1918 Mapping the Delta Historical Evidence
  13. “Depression-era program to ensure crop stability and soil conservation practices

    resulted in extensive aerial photographic coverage for much of the county. While the photographs were taken after substantial modification, the photos nevertheless reveal relict ecological features, traces of which are often still present in the landscape.” Aerial Photographs ca. 1937 Mapping the Delta Historical Evidence

  15. • ~400-page report to California Dept. of Fish and Game

    • In peer review during Summer 2012 • We worked from a draft copy • Just released to public last week A Rich Resource SFEI’s Report
  16. • Donationware application for Mac/Win/Linux • Feed in georectified hi-res

    image • Churns out tiles at specified zoom levels • Creates HTML wrapper for viewing Making Web Maps with MapTiler http://maptiler.org Web Development Turning the GIS into Map Layers

  18. • Free Javascript framework for combining map layers from different

    public and private APIs • Can mash up Google, Open Street Maps, Yahoo, Bing Maps with homemade tile sets, vector data from GeoJson, KML, WFS servers • A little less polished than some other kits, but very powerful and flexible Using OpenLayers to Combine APIs http://openlayers.org Web Development Open-Source Map Mashup Framework
  19. • Great introduction to OpenLayers • Covers all different map

    layer types • Symbology, mixing vector and raster data • Restyling and extending UI elements Learning More About OpenLayers Open Layers 2.10 Beginner’s Guide By Erik Hazzard Web Development Open-Source Map Mashup Framework
  20. • Explain basic concept of historical ecology • Introduce the

    components of the Delta • Show A/B comparison between 1800s & 2000 • Tell the story of the Delta’s different eras • Outline main findings of the report • Expose richness of imagery, original evidence, maps to users – especially more expert users • Be a map/database that doesn’t feel like a database • Allow images to escape from confines of the “speech bubble” of web maps Goals of the Interactive Feature Web Development Planning the Interactive Map
  21. • Pagination reduces need for complex menu system, enables more

    creative space on each “page” • Core of interactive feature is multi-layered web map instance • Rather than forcing all annotations and media into floating bubble windows, page is divided into regions over map • Interacting with map is possible on most pages; final page allows for free exploration The Plan
  22. Ended up using pagination to let users navigate from screen

    to screen Combination of narrative text with map “posed” to appropriate zoom level, center, and base map Text area with images has primacy on the page, rather than being in a tiny popup window but sometimes the map is more or less important Meant to be like an e-book Last page allows for free exploration Final version
