Place and Time Navigator
● Comparison of datasets with spatial or temporal Information
● Widget functionality● Interactive selection and highlight of data● Easy creation of (or integration into) own websites
for data display● Easy loading of own data● Easy analysis of own data for research● Open Source● https://github.com/skruse/PLATIN

History of PLATIN
● Europeana4D developed within Europeana● GeoBrowser developed within DARIAH● STIF developed by Stefan Jänicke for Fraunhofer IAIS● GeoTemCo developed by Stefan Jänicke at Image
and Signal Processing Department of the University of Leipzig
● PLATIN is a fork and extension of GeoTemCo● We thank their developers and funders!

Build upon Open Source
● Besides GeoTemCo PLATIN uses– jQuery / jQuery UI
– OpenLayers
– Flot
– Moment.js
– jsZip
– uCSV
● Also a big „Thank you!“ to these projects!

Base Widgets - Map
● clustering of „close“ data● Side-by-side comparison of datasets● Selection via shapes or even countries (on certain
maps)
![Page 6: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/6.jpg)
Base Widgets - Time
● Animation of a moving Time-Slice Selection● Data can be summarised by years/decades/centuries/ etc.
● More than just a „time slider“ - it contains distribution information and interacts with the other widgets!
● Scaling of values by logarithm

Base Widgets - Table
● Sortable by columns● PLATIN extensions:
● Creation of new dataset by selection● Download of dataset● Full-Text search of table data
![Page 8: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/8.jpg)
PLATIN Widgets – Data Loading
● Easy loading of● CSV / KML files on a server● JSON data in browser storage (localStorage)● CSV / KML files on the local PC
![Page 9: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/9.jpg)
PLATIN Widgets – Map Overlays
● Overlay map with a layer from XYZ-shapes or a KML-file or a WMS-layer
![Page 10: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/10.jpg)
PLATIN Widgets - Piecharts
● Display of any column● Own categories possible (subsummation of values)
![Page 11: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/11.jpg)
PLATIN Widgets – Uncertain Time
● Rewrite of Time Widget to allow Time-Spans● This Spans can represent uncertainty
● Objects only add a fraction of their „weight“ to a time-slice they overlap
● So each object will only add it's own weight to the „integral“ of the complete graph
● Scaling by logarithm or percentage (of total sum)
![Page 12: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/12.jpg)
PLATIN Widgets – Uncertain TimeID begin end
1 0 300
2 175 225
● Fuzzy or „uncertain“ plot displays a kind of density function
● Values represent „expected value“ at this point in time
![Page 13: Place and Time Navigator - Max Planck Society · History of PLATIN Europeana4D developed within Europeana GeoBrowser developed within DARIAH STIF developed by Stefan Jänicke for](https://reader034.fdocuments.us/reader034/viewer/2022042210/5eae634679aaeb148c29352e/html5/thumbnails/13.jpg)
PLATIN Widgets – Uncertain Time
● Time can also be displayed as a barchart, instead of the continuous graph
● Might allow easier data interpretation
