  1. ACE Technical Overview Paul Meyer, ACE Systems Engineer Rob Cermak, ARSC Life Sciences Informatics Support

  2. ACE Design - Guiding Principles • ACE is an open sourced, internet-based, open-access, Arctic-focused, environmental research and decision-support system that integrates data from existing remote sensing assets, products from existing and new environmental models, and in-situ reporting to provide monitoring, analysis, and visualization based on earth observation data and modeling. These products may be layered within an embedded KML-compliant viewer (e.g., Google Earth) and integrated into a community-based collaborative environment, as well as exposed through an Application Programming Interface (API).

  4. ACE Current Capabilities • Map Capabilities • Map Panes • Open at least two each of 2D/3D map viewing panes • Map panes maintain their own geographic region • Map panes maintain their own map projections • Map panes maintain their own zoom level • Map panes support independent layering of data • Provide a static selection of 2-D Mercator and Arctic Polar Stereographic projections • Limited support for: • Printing and screen capture • Measuring distance and area • Layering NetCDF / geoTIFF based data • Map Layers • Provide pre-populated Arctic Data sets in map pane catalogs • Layer KML based Data sets • Layer KMZ based data in Google Earth plug-in • Layer WMS based Data sets • Web Browser Capabilities • Open at least two web browser panes • Provide access to ACNFS data • Collaboration Capabilities • Content Management Web-based Portal • Create public and private collaboration areas • Allow authenticated users to upload data sources to collaboration areas • Share workspaces, files, KML, WMS, and Webpages to multiple users • Chat Capabilities • Conduct 1 on 1 and controlled group chat sessions • Chat history • Chat translation • Monitor chat rooms • An API that exposes the publicly viewable vetted data sets for external access • Search Capabilities • Data Catalog • System level • User Authentication Capabilities • Controlled secure access to ACE • Assignment of specific user roles and responsibilities to users • Access restrictions that support controlled access to private data

  5. ACE Future Capabilities • Map Capabilities • Map Projection Transformations • Route Planning • Setting of user preferences for Earth Coordinate format • Allow generation of user defined polygons • Draw a line, point, or region and determine available asset: • within the region • within a specified distance • Enhanced Support for: • Printing and screen capture • Measuring distance and area • Map Layers • Layer NetCDF based data • Layer HDF, GRIB, Shapefiles • Improved geoTIFF support • Worldview file support • Layer animation • Data age indicators • Collaboration Capabilities • Enhanced Content Management Web-based Portal • Versioning • Calendar function • Alert notification system • Enhanced Chat • Mobile device specific versions of ACE tools • Enhanced API capability

  6. ACE Supported OS/Browser pairings • Windows XP/Chrome • Windows XP/Firefox • Windows 7/Internet Explorer 9 • Windows 7/Chrome • Windows 7/Firefox • OSX (10.6, 10.7, 10.8)/Safari • OSX (10.6, 10.7, 10.8)/Chrome • OSX (10.6, 10.7, 10.8)/Firefox
