Presenting Spatial Data: Whats so spatial about spatial?

  1. 1. Presenting Spatial Data What’s So Spatial About it? Putting Yourself in My Place:
 Space, Place and Pattern ! 25 February 2014
  2. 2. No Lecture Next Week 4 March Will see you on 11 March
  3. 3. Did Anyone Happen to Try?: UnBuilding Grand Central Station
  4. 4. So … browsing the gallery: ! "Visual Complexity"
  5. 5. Visual Complexity Good Examples?? Inspiring Ideas?? ! Complexity? Patterns? Aethetics versus Clarity Can you visualise too much? What complications does the move into the visual realm introduce?
  6. 6. Minard x 2 New is Cool …but old classics rule!
  7. 7. Minard - Wheat and Exports
  8. 8. Snow
  9. 9. "Digitization makes the most traditional forms of humanistic scholarship more necessary, not less.
 But the differences mean that we need to reinvent, not reaffirm, the way we engage with the humanities."
  10. 10. Can We Understand Place without Space ‣ Need a wee bit of background in Geospace ! ‣ ‣ ‣ ‣ ‣ ‣ More than GIS Geovisualisation? Geoparsing? Georeference Geoparse Geotag ‣ ‣ ‣ ‣ ‣ ‣ Geocode Geolocate GPS GIS Projection Geovisualisation
  11. 11. Georeferencing ‣ ‣ Identify a place in space Usually a minimum 
 of Longitude, 
 Latitude, Altitude
  12. 12. Geoparsing ‣ ‣ ‣ Identifying an entity
 as a place as opposed
 to another type within
 a body of text; To assign geographic
 identifiers to words
 and phrases in
 unstructured content Useful Services: Metacarta / Calais / CalaisFull
  13. 13. Geotagging ‣ Add geographical
 reference information
 to media such as
 photographs, video,
 websites, blog
 posting, etc.
  14. 14. Geocoding ‣ ‣ The process of finding geographic coordinates from address data Reverse Geocoding
  15. 15. Geolocating ‣ Assessing the location of a real world object based on IPaddress, or mobile connection to the internet
  16. 16. Global Positioning Systems (GPSs) ‣ ‣ Series of US Defense Department Satellites in Orbit that allow for accurate positioning in three dimensions Additional services available from GLONAS (Russia) and emerging GALILEO (Europe) and COMPASS (China)
  17. 17. Geovisualisation ‣ The use of geographical representation to allow for analysis, decision-making and presentation
  18. 18. Geographic Information Systems (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
  19. 19. Geospatial Data Standards ‣ ‣ ‣ ‣ ‣ KML GML GeoRSS GPSX Boundary File/Shapefile
  20. 20. Keyhole Markup Language (KML) ‣ ‣ ‣ ‣ ‣ ‣ ‣ ‣ A language for the visualisation
 of geographic information Placemarks Ground Overlays Paths Polygons Styles Google Earth Can be embedded in TEI
  21. 21. KML Object Model
  22. 22. Geographic Markup Langauge (GML) ‣ ‣ Adopted by the Open Geospatial Consortium (OGC) Can be embedded in TEI
  23. 23. GML ‣ ‣ ‣ ‣ ‣ ‣ ‣ ‣ Feature Geometry Coordinate Reference System Topology Time Dynamic feature Coverage Unit of measure Directions ‣ ‣ Observations Map presentation styling rules
  24. 24. Place and the TEI ‣ ‣ ‣ Guidelines found in 13.2.3 Place Names and 13.3.4 Places in P5 First concerns naming of place (duh!) and the second the locating of the place in space (a little more complex) Placename ‣ ‣ <placeName @type/> or <geogName @type/> Place ‣ <place><placeName @type><location><geo/></location></ placename></place>
  25. 25. Place Naming ‣ placeName contains an absolute or relative place name to a geo-political reference. ‣ ‣ <placeName/ @key> eg. ‣ <placeName key=”FO-01”>
 <settlement type=””town”>OFFOY
 </settlement>
 <country type=”nation”>France
 </country>
 </placeName>
  26. 26. Place Naming ‣ ‣ ‣ geogName contains an absolute or relative reference to a geographic feature. <geogName/ @key @type> eg. ‣ <geogName key=”R01” type=”River”>
 <name>Somme</name>
 <geogFeature>River</geogFeature>
 </geogName>
  27. 27. Locating a Place ‣ ‣ place contains direct reference to the location of a place. eg. ‣ <place key=”offoy” type=”Town”>
 <placeName notBefore=”1450”>OFFOY</placeName>
 <location><geo>
 <kml:Placemark id=”OFF-01”>
 <kml:Point>
 <kml:coordinates>49.7634,3.0115
 </kml:coordinates></kml:Point>
 </kml:Placemark></geo></location
 </place>
  28. 28. Complicating Considerations ‣ Specifying a Coordinate System (default:WGS84) ‣ ‣ Dealing with places with different names at different times ‣ ‣ ‣ <placeName notAfter="0056">Lugdunum</placeName> <placeName notBefore="1400">Lyon</placeName> Dealing with relative locations ‣ ‣ Otherwise use GeoDecl in TEI Header <offset> or <measure> Specifying a GML and KML within the TEI ‣ <geo><kml:Placemark/></geo>
  29. 29. Temporality and the TEI ‣ Referenced in 13.3.6 of P5 ! ‣ The TEI Date ‣ ‣ <date @type @when/> where YYYY-MM-DD <time @type @when/> where HH:MM:SS ! ‣ The TEI Event ‣ <event @key @when/><label/><description/><placeName/>
  30. 30. Encoding a Date ‣ ‣ date contains reference to a date in any format. eg. 
 <date when=”1918-01-06”
 type=”Occassion”>
 6 January 1918
 </date> ! ! ! ! ! ‣ ‣ dates can be relative: eg. 
 <date when="--12-02">
 <date>A week</date>
 <offset>before</offset>
 <date when="--12-09">
 <date type="occasion">my birthday
 </date> on
 <date>9th December
 </date></date></date>
  31. 31. Encoding a Time ‣ ‣ Time contains reference to a specific granular time of day. eg. 
 <time when=”13:45:00”
 type=”twentyfourHour”>
 a quarter of two
 </time>
  32. 32. Complicating Considerations ‣ Don’t specify accuracy that doesn’t exist ‣ ‣ ‣ If a day missing from a date use “--” or extra seconds “00” Deal with other formats in transformation Dealing with relative time and date ‣ <offset>
  33. 33. Events Tie together Place and Time ‣ ‣ ‣ event contains contains data relating to any kind of significant event associated with a person or place. <event/ @when @type> eg. 
 <event type="battle" when="1918-03-21">
 <label>German Spring Offensive</label>
 <placeName>
 <region>Northern France</region>
 </placeName>
 </event>
  34. 34. Keyhole Markup Language KML ‣ ‣ ‣ ‣ As I mentioned earlier it’s a language for the visualisation of geographic information There’s many entities that we can define in KML, we will focus on places --> Placemarks Ground Overlays, Paths, Polygons, Styles All of which can be embedded in TEI
  35. 35. KML and Precise Place and Time ‣ ‣ ‣ ‣ ‣ ‣ ‣ ‣ ‣ ‣ ‣ <placemark/> <name/> <description/> <point> <coordinates/> <timeStamp/> <timeSpan/> <when/> <begin/><end/> <Folder/> <Document/>
  36. 36. Places to Visit ‣ ‣ ‣ ‣ ‣ Recipes: GIS Cookbook Reference for KML: KML Tutorial Standards: Open Geospatial Consortium News: Slashgeo Online Tutorial: MapSchool
  37. 37. How to Use Palladio
  38. 38. How to Use ARCGIS Online
