Pre-processing included a two-step procedure to eliminate slight band-to-band misalignment. This was done using customized software to first compute an overall x-y direction shift of bands 1, 3 and 4 relative to band 2. Each of the 4-band shifted image frames was then run through a Fast Fourier Transform (FFT)-based pattern recognition routine, which tiles the image into 80 pixel sections and computes a secondary, regional pixel shift on each band.
Image Georeferencing/Mosaicking: The pre-processed imagery was then run through an in house customized software package to auto-georeference each of the pre-processed frames based off of the DGPS time stamp from the DMSC and the time stamp from the IMU. Once auto-georeferenced, frames were manually adjusted (shifted and or rotated) where needed. OI mosaicked the individual DMSC image tiles into local coastal and island regions encompassing the SCR MPAs for more efficient classification and data management using ERDAS Imagine and ESRI ArcGIS software applications. Mosaicked imagery were then used to generate the habitat classification products. Final image mosaic files have been delivered to Sea Grant and Ocean Spaces in GeoTIFF (.tif) format.
Kelp data processing: This habitat classification product was created using the ESRI ArcGIS 10.0 and 10.1 Geoprocessing tools. Depending on the target region and habitat types, both supervised Maximum Likelihood and unsupervised Iso Cluster classification techniques were used. The 30cm UCX imagery was resampled to 1 meter to create the final thematic map product. As stated in the Data Source section, all of the image data were georeferenced, orthorectified and mosaicked into geographical segments based on the flight lines and then into local, coastal and island regions encompassing the SCR MPAs for more efficient classification and data management using ERDAS Imagine and ESRI ArcGIS software applications. The imagery was of very high quality and shows excellent spectral and spatial definition. Water penetration in areas of calm seas appears to be more than sufficient to classify offshore kelp.
Kelp Classification: For the classification products the image mosaics were then sub-sampled from 0.3 meter to 2 meter GSD. The 2 meter image mosaics are provided as part of this delivery package. Exposed kelp and submerged kelp classes were created and then merged using both supervised (Maximum Likelihood) and unsupervised (Iso Data) classification methods. In the final products the GRIDCODE =1 represents both the exposed kelp and submerged kelp. Thematic map claasifications are delivered in both raster (.tif) and ESRI shapefile (.shp) formats.OOcean Imaging (OI) owns and operates a 4-channel aerial imaging sensor - the DMSC - manufactured by SpecTerra, LTD in Australia. The unit incorporates 4 synchronized, progressive scan 1024x1024 CCD cameras with spectral range capability from 350-990nm. Data is captured in 12-bit format. The unit is integrated with a DGPS for synchronous frame location logging. The channel wavelengths are customized by the use of narrow-band (10-20nm) interference filters. Spectral sensitivity is also customizable through software controlled shutter speed. The DMSC is a portable system suitable for mounting on a variety of aircraft. It acquires successive image frames at a rate automatically computed from the DGPS-derived ground speed and user-specified frame-to-frame overlap margin. OI also owns and Inertial Movement Unit (IMU) which collects precise location, altitude, roll, pitch and heading of the DMSC. The IMU was run in tandem during image collection and data collected will be used in the post-processing of the imagery. OI used a filter combination of 451-551-710-850 nm Data Acquisition: Imagery for the California South Coast Region (SCR) was acquired on 12/08/2011 at an altitude of 12500 feet with 60% scene overlap resulting in an initial ground sampling distance of 2.0 meters. Imagery was acquired from a Cessna 206 aircraft by Ocean Imaging staff.MPAs Contained in this OI Aerial coverage area include:
