1 What s new in GIS RAL Retreat Oct 5, 2005

2 Overview GIS Initiative milestones Major activities in GALEON UNIDATA OGC project New functionality in ESRI software

3 GIS Initiative Team Olga Wilhelmi PI Terri Betancourt PI 2004 Jennifer Boehnert UCAR GIS Coordinator

4 Integrates knowledge across disciplines and social groups Promotes and supports the use of GIS as both an analysis and an infrastructure tool in atmospheric research and Addresses broader issues of data management and geoinformatics within atmospheric and related geo- and social sciences

5 GIS Initiative Program Elements GIS Program with five program elements: Education, Training & User Support Research In GIS Technology Research Enabled by By GIS Data Integration & Distribution Building Community

6 GIS Lab Distributed GIS service center has been in effect since December 2002 July 2004 GIS lab officially opened as a resource for all UCAR employees Education, Training & User Support GIS coordinator Hardware GIS and image processing software Data Reference materials GISsupport@ucar.edu

7 Atmospheric Data Modeling (ADM) Research In GIS Technology Leading atmospheric special interest group (>100 members from government, universities, the private sector) ADM - Community-based initiative and a working dialog between ESRI and atmospheric sciences community regarding atmospheric data representation and analysis challenges Conducted two data modeling workshops In process of developing a Conceptual Document (ArcGIS Atmospheric Data Model) Our collaboration with ESRI resulted in support for NetCDF files in ArcGIS ADM Workshop 1 - Seattle, WA, January 16-17, 2004 at NOAA PMEL Lab ADM Workshop 2 - San Diego, CA, January 14, 2005 at the Marriott Hotel & Marina

12 Focus on Interoperability, Data, Tools and Models Data Integration & Distribution GIS Climate Change Scenarios Project

13 GIS Climate Change Scenarios Project Goal: open NCAR s climate modeling work to: Educators and students Resource managers and planners Policy makers Geographers and other social scientists Climate impacts researchers Other GIS community Since February 2005 GIS data portal had: 7242 hits 2846 files downloaded

14 GIS Climate Change Scenarios Data Portal Complimentary to other data distributing centers Collaboration with NCAR Community data Portal Dynamic converter translates NetCDF files into shapefile format. Step-by-step process for on-line data access Currently available datasets include atmospheric and land variables for IPCC A1B IPCC A2 IPCC B1 IPCC 20 th century constant Present Day Control 1870 Control

15 GIS Climate Change Scenarios Preview and exploration of data on-line The map shows mean surface temperature for July 2099 (A1B scenario)

16 GIS Climate Change Scenarios Data analysis in ArcGIS 100-year ( ) change in mean July surface temperature

17 CCSM data in ArcGlobe

18 Users of GIS data portal To date we have more than 700 registered users from 60 countries 70 percent of users are from the United States

19 Climate Change Demo

20 New Develops in the GIS Industry Open GIS Consortium Web Coverage Server netcdf as an encoder ESRI New functionality New applications

21 OGC - UNIDATA - GALEON GALEON (Geo-interface for Air, Land, Earth, Oceans NetCDF) Interoperability Experiment Stefano Nativi, John Caron, Lorenzo Bigagli, Ben Domenico Standards based gateway needed between existing AIS data systems and traditional GIS world

22 Client Application Existing Technology In Oceans/Atmosphere Communities THREDDS OPeNDAP ADDE HTTP Catalog.xml AREA GRID Station NetCDF IOsp NetCDF-3 Jgoffs DMSP HDF5 NIDS GRIB GINI

23 Application OGC Data Service with NetCDF Dataset Protocols WFS WCS NetCDF Interface Static GIS Features GeoTIFF HDF-EOS DTED NITF GML OpenDAP ADDE netcdf file

24 Main Gateway Objectives Make communities aware of one another Build standard interface to the many netcdf/opendap data servers already in operation Allow traditional atmospheric data providers to migrate toward one standards-based service Allow traditional GIS clients to access netcdf/opendap datasets via standards-based interface Evaluate netcdf/opendap as WCS data transport (encoding) mechanism suggest extension if warranted

26 What s new in ESRI products Desktop ArcGIS Applications NetCDF functionality Server ArcEngine

27 ArcGIS Applications Data exploration Map making Data analysis

28 ArcScene Interactive Fish tank view Good for a small scale range Best at rendering geometry

29 ArcGlobe Interactive Global and 3D viewing Optimized to multi-scale viewing Great for very large raster data Also support vector and 3D symbols

30 Multidimensional ArcGIS 9.2 Extend existing functionality to support time and multidimensional data Animation manager learns how to use a variable such as time to set the animation sequence. Improve quality and interaction of charting and include as an animation object. Add support for the NetCDF data format building on existing layer capabilities.

31 Example animation

32 New Charting Package Scatter 3D Scatter Combine Multiple Charts

33 Linking Select a feature in the map, record in the table, or element in the graph and see it highlighted in the other windows.

34 Brushing Drag a selection box around features in the map, records in the table, or element in the graph and see it interactively highlighted in the other windows.

35 NetCDF in ArcGIS NetCDF data can be accessed through Raster Feature Table Direct Read no scratch files

36 NetCDF Tools in ArcGIS Make NetCDF Raster Layer Make NetCDF Feature Layer Make NetCDF Table View Raster to NetCDF Feature to NetCDF Table to NetCDF Select by Dimension

37 Using NetCDF Layer/Table Behaves the same as any layer or table in: Display Same display tools for raster and feature layers will work on netcdf raster and netcdf feature layers. Charting Driven by the table just like any other chart. Animation Multidimensional data can be animated through a dimension (e.g. time, pressure, elevation) Geoprocessing Tool A netcdf raster layer will work just like any other raster layer, same for feature layers and tables.
