Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. It's 100% free, no registration required.

I am looking for an alternative tool (proprietary or FOSS) that matches the functionality of Temporal Analyst for ArcGIS by DHI Software. The best I could get was the QGIS plugin Time Manager whose functionality I perceive is more for visualisation than analytical (similar to esri's Time Slider.)

[Data Analysis - the Temporal Analyst for ArcGIS offers a suite of tools for data analysis and processing, incl. basic statistics and arithmetics, time step resampling, gapfiling, distribution and CDF plots, duration curves, double mass and double scatter.]

I am not a statistician nor hardcore developer so the more the "point and click" I can get the better. Thank you for all the pointers.

Maybe Multitemporal Multivariate data visualization plugin for QGIS is closer to what you're looking for.

and if the included visualisations do not suffice you the plugin can easily be expanded to include new visualizations if needed. –  user2733 Apr 20 '11 at 21:01

That's what I am looking for, thanks. [looks like an eventual migration to QGIS is unevitable. :-) ] –  Erick Apr 21 '11 at 6:43

This is an interesting implementation from a former professor of mine at the University of Tennessee from a National Science Foundation project titled "Towards a GIS-based Analytical Time-geographic Framework for Physical and Virtual Activities:

http://web.utk.edu/~sshaw/NSF-Project-Website/default.htm

From the project web page: "The major goal of this project is to extend Hägerstrand’s time geography such that it can provide a comprehensive framework of representing and modeling both physical and virtual activities as well as the interactions between them. In addition, this research will design a space-time geographic information system (GIS) to implement the extended time-geographic framework."

Been playing with the extension, 'quick' results - am familiar with esri environment. The QGIS plugin seems the comprehensive solution.Thanks –  Erick Apr 21 '11 at 6:40
