Google Maps Visualisation

• Source data has specific location information (eg Tangipahoa, St. Helena Parish, LA)

• Initial uplift only captures some of this (LA – Louisiana)• Capturing more specific locations improves data quality• How do we discriminate?

• Solution – semi-automated processes• Automated processes identify the most likely match

candidates• Humans then choose the correct candidate• Created two tools for semi-automated geographical data

improvement• Table-based• Map-based• Rajan Verma, TCD MSc student

Improving data browsing

• Initial implementation of USPV browsing• Does not provide users with a way to visualise data spatially• Looks dull

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 644055.

Improving data browsing

• Balazs Pete, TCD MSc student• Allows users to easily select interesting subsets of data• Users can visualise spatial relations• Easy to use
