Title: OSSIM Technology Overview


1
OSSIM Technology Overview
  • Mark Lucas

2
Awesome
  • Open Source Software Image Map (OSSIM)

3
Design Goals
  • Open Source Software Infrastructure
  • Remote Sensing, Photogrammetry, and Image
    Processing Technologies
  • Provide for Rapid Prototyping and High
    Performance Computing

4
Open Source Projects
  • remotesensing.org founded in 1997
  • Federal Funding and Support
  • Multiple Certifications and Evaluations
  • Systems and Tools are being based on OSSIM

5
Open Source Leverage
  • Software Libraries
  • Tools
  • Systems
  • Relational Databases
  • Visualization

6
OSSIM Reviews
  • Used in the Intelligence and Defense Communities
  • NGA Certified Map Projections and Transformations
  • RPC Universal Sensor Model validated on NTM
  • Validated in NGA CELTIC Pathfinder 2003

7
Key Features
  • Dynamic Image Chains
  • Non-Destructive Parameter based on demand
    processing
  • Rigorous Sensor Modeling
  • Hyperspectral Capable
  • Parallel Processing (mpi)
  • Dynamic Plugin Architecture

8
Platform Independent
  • Linux
  • IBM AIX - (xlc compiler)
  • Mac OSX
  • Solaris
  • Windows

9
Image Chains
  • Dynamically Connectable Image Chains
  • Source gt Models gt Filters gt Combiners gt Output
  • Parameter Based, Non-Destructive Processing

10
Dynamic Plugins
  • Supports External Plugins
  • Dynamically Loaded at Runtime
  • Simple keyword based interface

11
Applying OSSIM
  • Tools, Applications and Utilities
  • Systems
  • GUI Applications

12

Systems - GeoClusters
  • Based on Open Source Software Components
  • Linux Operating System and Utilities
  • Web based user interface for Navigation and data
    selection
  • User picks Area of Interest, inputs, processing,
    product output specs and file format
  • Product Generated, User notified via email,
    fetches product via ftp link
