  1. The Future of Time in ArcGIS Steve Kopp

  2. Project Vision • Support time as a new element of feature, raster, and tabular data in ArcGIS. • Provide new tools for the ingest, management, exploration, visualization, and analysis of temporal data.

  3. Existing ArcGIS support for Time • Preliminary work has been done over the last few years as part of the Water Resources Data model and other data model projects. • Tracking Analyst extension – provides support for temporal visualization of vector data. • Aimed at visualizing the movement or change of features or phenomena through time, e.g. airplanes, census data, etc.

  4. Goals • Provide core functionality for temporal data display and analysis. • Provide a temporal data model to support both simple and complex temporal data needs. • Provide a toolset for developers and advanced users to extend the system.

  5. Data Access • Support new data formats. • NetCDF and HDF initially • Provide a framework and tools for building direct bridges to temporal data. • Provide guidelines on how to hook up other formats for direct use.

  6. Storage Guidelines • Document recommended “best practices” for how to organize and store tabular, feature, and raster data in file system and DBMS for efficient temporal use. • E.g. what’s the best way to store 10 yrs of daily observational data for 10 variables at 300 sample locations? What are the considerations?

  7. Temporal Display/Query Tools • Data Exploration (ESDA) • Cross sectional view • Multidimensional slices • Statistical charting • 2D and 3D Visualization • Application clock • Multiple linked data frames, charts, and tables synchronized to the same time step.

  8. Animation • Interactive temporal animation • Output to movie formats • Multiple animation tracks, as in 3D Analyst

  9. Data Management Tools • Gap filling • Time synchronization of datasets • Weekly, monthly, irregular time steps • Normalizing temporal data types • Instantaneous, step, step accumulated…

  10. Analysis Tools • Temporal Analysis • Space/Time clustering • Space/Time interpolation and query • Trend analysis • Time integrated Temporal Modeling • Simulation Modeling • Conditional simulation, Monte Carlo

  11. Current Research • NetCDF as a native format • Direct read as raster, point, table, or graph • Display like any other ArcGIS data source • Use directly in analysis • No conversion or intermediate file • What profiles/flavors are most important? • CF standards, others? • How to handle projection/datum?
