1 Dynamic Maps and Historical Context Jeanette Zerneke International Joint GIS-IDEAS and PNC/ECAI Conference December 2008

2 Dynamic Maps Roles and Functions of Dynamic Maps in Cultural Collections and Atlases Examples of Dynamic Map Integration

3 Dynamic Maps GIS, spatial databases, spatio-temporal web displays, and a host of related technologies for registering, storing manipulating, searching, analyzing, and displaying location and time data

4 Functions of Dynamic Maps Linking from maps to related web resources Linking from text to maps Combining spatial and temporal aspects Linking between maps, map layers, or from maps to different types of spatial and temporal data GIS / Spatial Analysis & visualization of results Integration of spatial information which does not easily overlay on contemporary maps and satellite imagery

5 From Maps to Info URL links from points on a map The primary use of spatio temporal information on the web remains linking from dynamic maps to associated data through URL links Using the map as a visual index to text, images or other maps Using the map as a map w/ annotation E.g., traffic maps

6 Mosques in China

7 From Text or Image to Map On the fly creation of maps from query results Links within documents to explanatory maps A spatial visual annotation of the text or image

Time Maps Combining spatial and temporal aspects in a single display Interactive map interfaces - enables interrogation of a time and space context

9 Time Maps Combining spatial and temporal aspects in a single display Interactive map interfaces - enables interrogation of a time and space context Displaying change over time on a map e.g., video or flash display Showing attributes e.g., charts, color changes, etc. in a spatio-temporal context

10 Animation: Video / Flash Display Animation displays a visual narrative of time and place Mission Video on You Tube

11 California Mission Indian Population

12 Integrating Spatial Information Integrating maps and/or map layers Visualization of comparisons Navigation as dynamic filtering Spatial analysis Linking between maps and other types of spatial and temporal data Text descriptions and historical maps Diverse cultural expressions of time and space Images, stories, songs, diagrams, etc.

13 Methods of Implementation GIS and geospatial databases w/ web display application Google Earth/Maps - kml / xml data Contextualizing, annotating of text / xml data Using web resources and services Mashups, linking to services, using API s etc The choice has an impact on visualization

14 Case Study: Medieval Latin Places A quick prototype testing integration and visualization options Begin with place name lists Latin Place Names with reference to modern place names in early 20th century Link modern place names to contemporary gazetteer Identify latitude and longitude and reference number from contemporary gazetteer

15 Orbis Latinus - Letter A

17 Dynamic Map Integration Implement web display of linkage to modern places with web map Implement Google Earth Map with capability of linking to web resources

20 Spatial and Temporal Links Identify temporal information sources Identify historical maps Link to historical atlas data Link to Medieval maps with annotations

24 Hereford Mapa Mundi 1300ce

28 Explorations Enable multiple routes of navigation Modern map/satellite image - to text and historical map images Text to modern map and historical map image Medieval map to current information Next experiments Implement time annotation Link to references in published works Link from Medieval map to contextual information

29 Results Development is technically possible and not difficult Availability of adequate resources is an issue copyright for published maps and texts Primary questions of interest are digital scholarship issues How will the visualizations be read by users now How can the nuances of precision, accuracy and completion be represented Can the new systems be used to simulate old paradigms What is the new paradigm of spatio-temporal understanding that is developing

30 Spatio-temporal temporal Thinking Primary questions of interest are digital scholarship issues How will the visualizations be read by users now How can the nuances of precision, accuracy and completion be represented Can the new systems be used to simulate old paradigms What is the new paradigm of spatio-temporal understanding that is developing

31 Scholars and Learners Multiple products - different interfaces A scholars reference tool Historical Gazetteer Enabling linking of contextual information w/o having to recreate the gazetteer Enabling community input and editing A learners tool navigation, browsing, exploring linking contextual information providing narratives helping visualize the world as it was understood
