1. Geographic Search & Display Updates & Development Plans
Leila Gonzales
American Geosciences Institute

2. Updates since VuFind 3.1 Configuration Settings Geographic Searching
Check for poorly formed coordinate sets when indexing (PR-964, PR-998, PR-1034)
Update coordinate field names, add dynamic fields (PR-996)
Upgrade from OL3.x to OL4.2.0 (PR-1012)
Geographic Searching
Change search box to a click-drag functionality (PR-1013)

3. Updates since VuFind 3.1 Geographic Display
Display rectangles across the dateline (PR-964)
Close pop-ups when zooming/panning (PR-997)
Configurable option for displaying a graticule (lat/long grid) (PR-1014)

4. Development Planning Move to a lightweight platform (Leaflet)

5. Development Planning Refactor & modularize
Make code into a smaller set of classes that can be configured to turn on/off for different functionality
Increase configurable options
Improve search result clustering / geo display
multiple coordinates for a record - point, city, county, state, country
scale to specific coordinate level based on map extent

6. Geographic Indexing
Stick with points and bounding boxes as coordinate features…for now…
Pros –don’t need to install JTS Topology suite
Cons – can’t store complex polygon data
Investigate JTS Topology suite as possible option to allow for polygon storage and query
How easy is it to install & configure?
Improve error trapping by dumping errors to csv log file and notifying user at end of indexing.

7. Geographic Indexing Generate coordinates from bibliographic data
Start with field 653a, but could extend to include title and description fields.
Generate coordinates from full-text data
Examine frequency of places mentioned in full-text
Issues to consider:
Misspelled place names
Creation of duplicate and similar (almost duplicate) coordinates
Place names indicating publisher

8. Geographic Indexing
Improve existing error trapping by dumping errors to log file and notifying user at end of indexing run.
Create log file for errors / questions when creating geographic coordinates from metadata.
Have some way for users to verify data… maybe as simple as updating record to include suggested coordinate data?

9. Geographic Searching Configurable options Search Result clustering
Location of Geographic Search UI
Search tool options (box, circle, freeform polygon)
To display or not to display: geo-search results
Search Result clustering
Hover-over cluster and display center points of records included in cluster
Display coordinate set for record based on map extent. (i.e., point, city, county, state, country)

10. Geographic Display- Map Tab
“More Like This” / “Similar Items”
Display similar items in different color from record’s geo-features
Pop-up would show title of geo-feature with link to that feature (like existing search results clusters)
