WHO’S PRESENTING?


INTRODUCING YOURSELVES


A QUICK DEMONSTRATION


TALKING TERMS


What is Geospatial?

• More than GIS• Its all about Space and Place• Geovisualisation?• Geoparsing?


What is Geospatial Not?

• Automatic


A Bit of a Glossary

• Georeference• Geoparse• Geotag• Geocode• Geolocate

• GPS• GIS• Projection• Geovisualisation


Geo Referencing

• Identify a place in space• Usually a minimum of Longitude,

Latitude, Altitude


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


Geotag

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


Geocoding

• The process of finding geographic coordinates from address data

• Reverse Geocoding


Geolocating

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


Global Positioning System (GPS)• Series of US Defense

Department Satellites in Orbit that allow for accurate positioning in three dimensions


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


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


Geovisualisation

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

A project of the

‘GIS at theDiscovery Programme’

Mr Anthony CornsThe Discovery Programme


A project of the

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?


A project of the

Lunch


A project of the

Reports from Breakout Sessions


A project of the

Geospatial Standards


Standards

• KML• GeoRSS• GML• GPSX• Boundary File (shapefile)


KML

• Keyhole Markup Language• The Google Standard


KML• A language for the visualisation of

geographic information– Placemarks– Ground Overlays– Paths– Polygons– Styles


KML


KML

• Google Earth


GML

• Adopted by the Open Geospatial Consortium (OGC)

• Can be embedded in the TEI


GML

• Feature• Geometry• Coordinate

Reference System• Topology• Time

• Dynamic feature Coverage

• Unit of measure• Directions• Observations• Map presentation

styling rules


GeoRSS

• RSS (Really Simple Syndication)• An interchange format for changing

information – a feed• RSS with Geotagged Posts and Objects• See: GeoFeeder


A project of the

Geospatial Tools


Tools

• Google/Yahoo Maps

• Google Earth• Yahoo Pipes• GPSBabel• Simile Exhibit

• Many-Eyes• ESRI ArcGIS• OpenGRASS• Name Authorities


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)


Google Earth

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


Yahoo Pipes

• A transformational means to represent data in a geospatial means

• View Flickr Demo


GPS Babel/GPS Visualiser

• GPS Visualiser• GPSBabel


Name Authorities

• Alexandria Digital Library• Logainm• Getty


Next Steps

• Recipes: GIS Cookbook• Standards: Open Geospatial Consortium• News: Slashgeo


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


A project of the

Issues for Analysis

How can humanists use geospatial techniques/methods to pose research questions

and aid in analysis and exploration?


The Research Process

• Why should I use geographic information?

• What type of questions can I ask of it?


Issues for Humanities Research Analysis• Experimental• Limited Usage• Fluid Practise• Standards still

being set• Collabourative

• Limited Support• Steep Learning

Curve


A project of the

Issues for Presentation

How can geospatial techniques help to present research findings in the humanities?


Issues

• Type of Map• Type of Chart• Colour• Scale• Data

Representation

• Interoperability


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
