Simple (webservice) enhancements at the portal

• Projections
• File conversionascii2shp, grid2geotiff,
  shape2kml, raster2kml, ascii2scene and
  raster2scene
• Ties into both GoogleEarth (kml) and GeoWall
  communities (fledermaus)

The Vision

• Utilize the cyberinfrastructure developed by GEON
  to offer online data distribution, interpolation
  to grid, and analysis of large LiDAR datasets.
• Utilize modular web services to complete a
  variety of processing and analysis tasks.
• Completely internet-based workflow
• Point cloud to visualization
• Offer users control of interpolation and analysis
  parameters.

Next phases of GLW-I

• Seamless nesting of vector and raster data
  emphasizing ALSM and GBL/TLS
• 2.5D (mostly ALSM) Integration of imagery and
  ALSM, more DEM analysis tools, different methods
  for and faster gridding
• 3D (mostly GBL/TLS) True 3D surfaces
  (triangles/NURBS) with texture mapping of imagery
• Take it to the field and to the desktop increase
  interactivity by format conversion and software
  development
• Dynamic metadata, job control, monitoring
• ALSM Airborne Laser Swath Mapping
• GBL Ground Based Lidar
• TLS Terrestrial Laser Scanning

17
Next phases of GLW-II

• Two tracks
• Production
• Continue to support and expand hosted data
• Develop/deploy Lidar in a box using GEON/Rocks
  tools and optimized hardware configuration to get
  other data providers up and running with DB2
• Educationlots of geomorphology can be taught
  with these data at a variety of levels
• RDdevelop the next set of GLW elements for both
  IT enhancements as well as increased usability,
  research product quality and diversity, and
  teaching.
