Ocean Imaging 20130417 vector digital data http://bios.dfg.ca.gov ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/1100_1199/ds1195.zip This vector dataset contains habitat classification of the offshore giant kelp beds along the California North Central Coast region from Pigeon Point up to Point Arena, including select bays and river mouths designated as MPAs. [This is an aggregated dataset of the 15 California North Central Coast kelp habitat shapefiles. The shapefiles were aggregated into a single feature class for better functionality in BIOS.] This vector 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). Ocean Imaging acquired the imagery used for this analysis on 11/02/2010 using the Digital Multispectral Camera (DMSC). 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. Details on these systems and the data processing are below in the Lineage section of this document. Individual DMSC and ADS40 image tiles were mosaicked into sections based on the USGS orthoquads for the California North Central Coast in order to generate the image products required to generate this merged kelp habitat classification covering the California North Central Coast’s kelp beds from Pigeon Point up to Point Arena. The MPAs contained in each of the USGS orthoquads as well as additional information on the classification procedures used are outlined in the Lineage section of this document.

Littleton Colorado 80127 US 303-948-5272 mhess@oceni.com M-F 9:00 AM - 5:00 PM MST Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.2.2.3552 None 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 habitat 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. DMSC Data Processing: Upon completion of each flight, image data were downloaded from the DMSC onto an in-house computer hard drive and back-up copies were burned on DVD's. 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. Adjusted frames were then mosaicked into USGS orthoquad regions for more efficient classification and data management using ERDAS Imagine. Mosaicked imagery was then used to generate this kelp habitat classification products. Final image mosaic files have been delivered to Sea Grant and Ocean Spaces in both ERDAS Imagine (.img) and GeoTif (.tif) formats. Classicification products have been delivered in both .img and ESRI Shape File formats. The California Department of Fish and Wildlife aggregated 15 individual kelp habitat shapefiles for the California North Central Coast. The shapefiles were merged into this feature class for better functionality in BIOS.] Vector GT-polygon composed of chains 287783 Grid Cell 15430 13532 NAD 1983 California Teale Albers 34.0 40.5 -120.0 0.0 0.0 -4000000.0 coordinate pair 0.0001 0.0001 meter D North American 1983 GRS 1980 6378137.0 298.257222101 ds1195 OBJECTID Internal feature number.
