      <abstract>This raster dataset contains a classification of kelp bed persistence between the years of 1999-2010 along the California North Central Coast region.</abstract>
      <purpose>[This is an aggregated dataset of the 21 California North Central Coast kelp persistence rasters.  The raster datasets were aggregated into a single 2 meter raster for better functionality in BIOS.]
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------    

This raster dataset was developed for the Sea Grant MPA Baseline Program as part of the project “High Resolution Nearshore Substrate Mapping and Persistence with Multispectral Aerial Imagery” (#R/MPA17 09-015). The study region is the California North Central Coast (NCC). This dataset is a thematic classification of kelp persistence between the years of 1999-2010 along California North Central Coast’s intertidal to offshore region from Pigeon Point up to Point Arena. In that time period, kelp maps from 2000, 2001, 2007 and 2009 were unavailable and so the persistence analysis was created using data from the eight years 1999, 2002, 2003, 2004, 2005, 2006, 2008, and 2010.  The imagery used for this habitat classification were collected by Ocean Imaging (OI), Fugro EarthData and the California Department of Fish and Wildlife (CDFW).   Details on the data sources and processing are below in the Lineage section of this document. Kelp classifications in the form of ESRI shapefiles were acquired from the CDFW for the years of 1999, 2002, 2003, 2004, 2005, 2006 and 2008.  For the 2010 kelp classification used in this analysis Fugro EarthData acquired the imagery between 09/22/2010 – 09/23/2010 and OI acquired this imagery on 03/26/2010 using the Digital Multispectral Camera (DMSC). Details on these systems and the data processing are below in the Lineage section of this document.  The kelp presence for each available year were summed together for every 2 meter cell in the study region thus creating eight classes of annual kelp persistence during the 1999-2010 time period. </purpose>

        <srccontr>The OI analyses for 2010 were created as part of this Sea Grant project and the remaining analyses were obtained from the CDFW server ftp://ftp.dfg.ca.gov/R7_MR/BIOLOGICAL/Kelp/.   Ocean 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 Central-Northern California coast kelp mapping was acquired on 11/02/2010 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. Ocean Imaging (OOI) acquired 4-banded, multispectral Orthoimagery from Fugro EarthData’s (http://www.fugroearthdata.com/index.php) Leica ADS40-SH52 digital camera system. The ADS40 is a 12 CCD pushbroom sensor with a raw camera resolution of 3,000 x 2,000 pixels for the multispectral data. It utilizes 4 panchromatic CCD: 27 degrees forward view, 16 degrees backward view, two nadiral views with an overlapping of 3,25 microns and 2 x 4 multispectral CCD (red, green, blue and near infrared – RGB-NIR), with both a nadiral and 16 degree backward views. There are five spectral channels measuring simultaneously: panchromatic, red (λ = [590 – 675]nm), green (λ = [500 – 650]nm), blue (λ = [400 – 580]nm) and near infrared (λ = [675 – 850]nm). The RGB-NIR bands were used for this project. Fugro EarthData acquired the imagery used for this project between 09/22/2010 – 09/23/2010 and delivered fully georeferenced and orthorectified, 12-bit imagery with a spatial resolution of 0.30 meters to OI in 2011. The initial imagery products received from Fugro were mosaicked into 1500x1500 meter tiled imagery along the California coast. OI subsequently mosaicked the ADS40 data into USGS orthoquad regions for more efficient classification and data management using ERDAS Imagine. Mosaicked imagery was then used to generate the kelp classification products. Final image mosaic files have been delivered to Sea Grant and Ocean Spaces in both ERDAS Imagine (.img) and GeoTif (.tif) formats. ADS40 imagery used for the kalp classification were resampled to a GSD of 1.0 meters.
