Hi Cedrick, welcome back in the community.
Thanks, I was not very far though ^^
For a project Iâm starting to prototype, I need collections where objects are inserted according to an index that is a spatiotemporal object.
The idea is that each time a person add an « information" in this collection, he does it a a given place and time and I want to be able to query the collection easily according to place or time (or both).
Iâm hacking it right now but I wonder if people have ideas on that subject. Iâm also interested in collection that that are indexed by the timestamp of the insertion.
For the implementation of spatiotemporal classe, I choose to use a ZTimestamp and a Geolocation object. Geolocation is quite simple and is responsible among other to get the timezone, but of courses coordinates (or eventually areas).
For the collection, Iâm still wandering⦠Something like an OrderedCollection with another internal array to store associated spatiotemporal(s)⦠Will hack something but Iâd love to hear others ideas.
You mean something like a timeseries ? I start to work on a basic TimeSeries class quite similar to the one you find in Panda: http://pandas.pydata.org/pandas-docs/stable/timeseries.html <http://pandas.pydata.org/pandas-docs/stable/timeseries.html>
I donât really know, more a geospatial timeserie but It might be interesting. Weâll exchange on that subject I guess. Cheers, Cédrik
