RAL Retreat Oct 5, 2005

Overview

GIS Initiative milestonesMajor activities in 2004 - 2005

GALEON – UNIDATA OGC project

New functionality in ESRI software

GIS Initiative Team

Olga Wilhelmi – PI

Terri Betancourt – PI 2004

Jennifer Boehnert – UCAR GIS Coordinator

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

Atmospheric Data Modeling (ADM)

ResearchIn 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 NetCDFfiles 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

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

What’s new in ESRI products

Desktop ArcGIS ApplicationsNetCDF functionality

ServerArcEngine

ArcGIS Applications

Data exploration

Map making

Data analysis

ArcScene

Interactive “Fish tank” view

Good for a small scale range

Best at rendering geometry

ArcGlobeArcGlobe

Interactive Global and3D viewingOptimized to multi-scale viewingGreat for very large raster dataAlso support vector and 3D symbols

Multidimensional ArcGIS 9.2Extend 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.

Example animation

New Charting PackageScatter

Combine Multiple Charts

LinkingLinking

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

BrushingBrushing

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.

NetCDF in ArcGIS

NetCDF data can be accessed throughRasterFeatureTable

Direct Read – no scratch files

NetCDF Tools in ArcGISMake NetCDF Raster Layer

Make NetCDF Feature Layer

Make NetCDF Table View

Raster to NetCDF

Feature to NetCDF

Table to NetCDF

Select by Dimension

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.
