Place and Time Navigator
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)
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
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
PLATIN Widgets – Map Overlays
● Overlay map with a layer from XYZ-shapes or a KML-file or a WMS-layer
PLATIN Widgets - Piecharts
● Display of any column● Own categories possible (subsummation of values)
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)
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
PLATIN Widgets – Uncertain Time
● Time can also be displayed as a barchart, instead of the continuous graph
● Might allow easier data interpretation
PLATIN Widgets – Line Overlay
● Visualisation of a relation (undirected or parent-child) of datasets
● Is also interactive with highlight and selection!
PLATIN Widgets – Shape Coloring
● Coloring of a map in relation to distribution of data● Also interactive with highlight and selection!
Structure of the CSV files● Name
The name of the dataset shown in the table.● Address
The name of the location shown in the map.● Latitude/Longitude
WGS84 Coordinates● TimeSpan:begin● TimeSpan:end
Dating information shown in timeline● Any other column
Information shown in table
Example of a CSV file
Structure of the CSV files
● NameThe name of the dataset shown in the table.
● AddressThe name of the location shown in the map.
● Latitude/LongitudeWGS84 Coordinates
● TimeSpan:begin● TimeSpan:end
Dates
Can be „virtual“ position information!
Virtual GeoData● Replace two columns with ordered numerical
data, that represents a „virtual“ location.Preposition „Coordinate“
