Shapefiles

  • Ortho Date Flown – 2009 (.ZIP format) 37 MB – 10/8/09
  • Mosaic Grid – 2008 (.ZIP format) – 03/31/09
    The mosaic grid was created to break up the mosaics into manageable 1 GB files.
  • Pictometry Clusters – 2008 (.ZIP format) – 03/04/09
    This grid of the Pictometry oblique imagery clusters can be used to locate Pictometry sector files in their data file listing. The cluster folder is named according to the northwest sector within that cluster; each cluster contains up to 25 sector folders.
  • Project Areas -2008 (.ZIP format) – 03/04/09
    Boundary of areas where various data products were captured. Area 1 is often referred to as the “urban” area (this does not refer to land use type as there are many rural and uninhabited locations within this “urban” area). Area 2 covers the national forest areas; datasets for Area 2 were captured at a reduced resolution. Area 3 covers Santa Catalina Island; consists of the same data products and resolutions as the “urban” area.
  • Superblock Layout (.ZIP format)
    Boundary of delivery areas based on aerial triangulation reports and processing.
  • Significant Grading Identified (.ZIP format)
    Areas identified with significant grading since 2006 for LAR-IAC2 DEM spot updates. Download and check against projects within your jurisdiction.
  • Ortho Imagery Grid (.ZIP format) – revised 03/09/09
    One-foot pixel resolution ortho imagery coverage of National Forest areas and Four-inch pixel resolution ortho imagery coverage of the urban project area and the Santa Catalina Island area.
  • Pictometry Grid (sectors) (.ZIP format)
    One-square mile sector grid for oblique aerial digital imagery.

All shapefiles are in the following coordinate system: CA State Plane Coordinate System, NAD 83, Zone V, US Survey Feet.

Services (NEW!)

LAR-IAC2 Data Viewer – This service maps the various grids available for the Los Angeles Region Imagery Acquisition Consortium (LAR-IAC2) Project. Here you will find the various grids and boundary layers that make up the setup of the project.

  • Tile grids (4″ and 1′ products)
  • Project areas
  • Date flown shapefile (dissolved to the image chip level)
  • Pictometry sector and cluster grid (for oblique imagery0
  • Delivery areas (superblocks)
  • Mosaic grids (for ECW and MrSID deliverables)

** Note that the shapefiles for these are available below – but here you can view directly with theArcGIS.com web viewer.
