  2. Welcome • Aim • Assumptions • Objective

  3. Agenda • Introduction • Demonstration • Dr Rob Sands • Shawn Day • Anthony Corns • Breakouts • Standards • Tools • Mash-up Exercise • Issues for Analysis & Presentation • Discussion and Wrap-Up

  4. WHO’S PRESENTING?

  5. INTRODUCING YOURSELVES

  6. A QUICK DEMONSTRATION

  7. TALKING TERMS

  8. What is Geospatial? • More than GIS • Its all about Space and Place • Geovisualisation? • Geoparsing?

  9. What is Geospatial Not? • Automatic

  10. A Bit of a Glossary • Georeference • Geoparse • Geotag • Geocode • Geolocate • GPS • GIS • Projection • Geovisualisation

  11. Geo Referencing • Identify a place in space • Usually a minimum of Longitude, Latitude, Altitude

  12. Geoparsing • Identifying as a place as opposed to another type of entity within a body of text • To assign geographic identifiers to words and phrases in unstructured content • Metacarta / Calais / CalaisFull

  13. Geotag • Add geographical reference information to media such as photographs, video, websites, blog posting, etc.

  14. Geocoding • The process of finding geographic coordinates from address data • Reverse Geocoding

  15. Geolocating • Assessing the location of a real world object based on IP-address, or mobile connection to the internet

  16. Global Positioning System (GPS) • Series of US Defense Department Satellites in Orbit that allow for accurate positioning in three dimensions

  17. Geographic Information System (GIS) • GIS can display spatial data hidden in tables and databases • Create detailed and intelligent maps • Integrate data to reveal trends and relationships that bring new perspectives to previously held beliefs about people and places • Research questions in the humanities often involve a spatial component that only GIS can expose

  18. Projection • The means by which we represent a sphere on a plane • The earth is round, but we project it onto a flat surface to display data • See: Flexprojector

  19. Geovisualisation • The use of geographical representation to allow for analysis, decision-making and presentation

  20. ‘From Bits of Data to Maps’ Dr Rob Sands, UCD

  21. Time and Space:How an Historian Approaches the Digital Arts and Humanities Shawn Day 21. 05. 2009 - Introduction to Geospatial Methods for Humanities Research

  22. ‘GIS at theDiscovery Programme’ Mr Anthony Corns The Discovery Programme

  23. Breakout Sessions How do you think that the use of or addition of a geospatial dimension can aid in the framing of your research questions?

  24. Lunch

  25. Reports from Breakout Sessions

  26. Geospatial Standards

  27. Standards • KML • GeoRSS • GML • GPSX • Boundary File (shapefile)

  28. KML • Keyhole Markup Language • The Google Standard

  29. KML • A language for the visualisation of geographic information • Placemarks • Ground Overlays • Paths • Polygons • Styles

  30. KML

  31. KML • Google Earth

  32. GML • Adopted by the Open Geospatial Consortium (OGC) • Can be embedded in the TEI

  33. GML • Feature • Geometry • Coordinate Reference System • Topology • Time • Dynamic feature Coverage • Unit of measure • Directions • Observations • Map presentation styling rules

  34. GeoRSS • RSS (Really Simple Syndication) • An interchange format for changing information – a feed • RSS with Geotagged Posts and Objects • See: GeoFeeder

  35. Geospatial Tools

  36. Tools • Google/Yahoo Maps • Google Earth • Yahoo Pipes • GPSBabel • Simile Exhibit • Many-Eyes • ESRI ArcGIS • OpenGRASS • Name Authorities

  37. Google Maps/Yahoo Maps • 2D generally • Provide API so that you can annotate with your own data • Allow georeferencing, geolocation and geocoding • Visit the Maps (Plot KML)

  38. Google Earth • 2D/3D and as was saw before even 4D • Open API and very sophisticated • Available as a Plugin for Browsers

  39. Yahoo Pipes • A transformational means to represent data in a geospatial means • View Flickr Demo

  40. GPS Babel/GPS Visualiser • GPS Visualiser • GPSBabel

  41. Name Authorities • Alexandria Digital Library • Logainm • Getty

  42. Next Steps • Recipes: GIS Cookbook • Standards: Open Geospatial Consortium • News: Slashgeo

  43. Exercise/Hands-On: Finding Yourself • Raw Materials: Excel Spreadsheet of Participants, IP Address and Physical Location • Tools: Google Earth, Excel, MaxMind • Objective locate all members of workshop and create usable map view for presentation

  44. Issues for Analysis How can humanists use geospatial techniques/methods to pose research questions and aid in analysis and exploration?

  45. The Research Process • Why should I use geographic information? • What type of questions can I ask of it?

  46. Issues for Humanities Research Analysis • Experimental • Limited Usage • Fluid Practise • Standards still being set • Collabourative • Limited Support • Steep Learning Curve

  47. Issues for Presentation How can geospatial techniques help to present research findings in the humanities?

  48. Issues • Type of Map • Type of Chart • Colour • Scale • Data Representation • Interoperability

  49. Wrap-Up • How have your ideas possibly changed since our breakouts? • Where do questions remain? • What else would you like to see covered in future events? • Complete feedback forms

  50. The Geostack
