1 # PLATIN
2 Place and Time Navigator
3
4 a fork and extension of [GeoTemCo](https://github.com/stjaenicke/GeoTemCo)
5
6 developed at the [Max-Planck-Institute for the History of Science](http://www.mpiwg-berlin.mpg.de) with funding from [TOPOI](http://topoi.org) within the Project [Atlas der Innovationen](http://www.topoi.org/group/d-6/).

8 ## Introduction
9
10 PLATIN is a HTML5-based tool for presentation and analysis of spatial and temporal data, with a focus on historical data.
11
12 The projects starting goal was to bring the functionality of the [DARIAH](http://www.dariah.eu) [GeoBrowser](http://dev2.dariah.eu/e4d/‎) to [GeoTemCo](http://www.informatik.uni-leipzig.de/geotemco/).
13
14 Which added the following functionality:
15 * CSV loading
16 * loading of URL-specified datasets
17 * deletion of datasets and refining of datasets
18 * exporting of datasets (to KML or CSV files)
19 * an UI that leaned on the GeoBrowser layout
20 * full-text search of table data
21 * WMS and KML overlays
22 * time-intervals
23 * upload of data to a data-store
24
25 ## Important additional features
26
27 The widget-architecture of GeoTemCo led to the creation of following additional features:
28
29 ### Dataset loading via URL
30
31 Datasets in KML/CSV/JSON format can be loaded via URL. Those attributes of those datasets can be changed, if they don't follow the PLATIN syntax style. Also datasets can be filtered via URL.
32
33 ### Pie Charts
34
35 Piechart can be created for each "column" of a dataset. The data can either be the distinct values,
36 categorized, or even generated by an own function (that takes the objects value as an argument).
37
38 They are interactive with the other widgets, so a selection/highlight of a pie chart slice will
39 select/highlight those objects in the other widgets. And a selection/highlight in another widget
40 will reduce the piechart to those selected/highlighted values.
41
42 ### Fuzzy Timeline
43
44 If the dataset has uncertain time-data (as with historical/archaeological data) this uncertainity
45 should be shown and represented in the time-plot. The fuzzy timeline will add an object in such a
46 way, that its weight is equaly spread across the timespan that is attached to it.
47
48 Also it is possible to switch to a bar-chart representation of the data. With bar-intervals of e.g.
49 1,10,100,... years.
50
51 ### Directed Line-Overlay
52
53 With this widget it is possibile to add "lines" (optionally arrows) between objects on the map.
54
55 If objects are clustered the links will be inherited and line thickness will be increased if
56 lines are doubled by this clustering.
57
58 ### Dataset coloring on element (DataObject) basis
59
60 Each DataObject can have an own color, if objects are clustered together, the cluster color
61 is calculated as the average of the RGB values.
62
63 ### Dataset color and shape changing (by user)
64
65 (This feature is in beta-state.)
66
67 Color and shape (on map) of the datasets can be changed on-the-fly from a dropdown menu in the table header.
68
69 ### Story-Telling
70
71 (This feature is unstable and under heavy development.)
72
73 As this tool also has an focus on data-analysis, it can be interesting to
74 * record the steps of selection/piechart creation/dataset refining
75 * go back a step or more in this history of data transformation
76 * branch this history
77 * save this history
78 * send this history to other persons
79 * create a presentation, or animation, of that history
