Field points used for training sites were also provided by DFO. Note that photosynthetic spectral responses were all assumed to be eelgrass and not other species (e.g. Ulva), so results may overestimate eelgrass in areas where other submerged aquatic vegetation is present.

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This layer represents the eelgrass distribution in the Pugwash Estuary as of August, 2014. The methods and analysis leading to the creation of this layer is as follows:</SPAN></P><P><SPAN STYLE="font-weight:bold;">Methods:</SPAN></P><P><SPAN>Aerial imagery was taken August 20, 2014, between the hours of 12:50pm-2pm where low tide was 0.6m at 12:44pm, by a Cessna high winged aircraft equipped with a vertical photo hole in the belly. A Canon 1DX - 18MP camera with a 35mm lens was used for the true colour photos and a specially modified IR version of the Canon 5DMarkI 13MP camera with a 35mm lens was used for the infrared photos. The area was flown in parallel lines, at 2000ft for the color imagery and at 4000ft for the IR imagery.</SPAN></P><P><SPAN>Roughly 1500 JPEG images were taken for the color map, of which roughly 1000 were used to assemble the final large map. The IR images map was made from about 700 images. Agisoft's Photoscan and Photoshop CS5 softwares were used to assemble the map, using both TIFFs and JPEG file formats depending on the size of the map. The map was assembled into strips, which joined one at a time to form a larger piece. Some manual editing was needed to join some of the images. </SPAN></P><P><SPAN>To compile individual images into one large image of the estuary, the resolution was reduced slightly (~10-15%) due to the limitations in file formatting (JPEGS can't be any more then 1.0GB and TIFFS can't be any more then 4.0GB in size). That means individual files and smaller compiled images have slightly more detail then the image of the entire estuary.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Analysis: </SPAN></P><P><SPAN>The analysis was completed by NCC staff using ArcGIS 10.1. First, the image was georeferenced to ESRI basemap imagery using a third-order polynomial and the cubic convolution resampling technique was employed in the georeferencing process. </SPAN></P><P><SPAN>Due to initial issues converting rasters to vector formats, the initial imagery was resampled using cubic convolution into a 5m pixel size. Then, using the Image Classification Tool, a maximum likelihood classification was run to classify the imagery based on the pixel value. The dense and sparse classes were extracted from the raster and converted to a vector format (shapefile). Polygons less than 25m² were deleted, and polygons within 15m were aggregated (clumped together. Finally, manual editing was required to edit the classified areas since the pixel classification had issues differentiating between water and eelgrass, qualifying sparse beds as they were a combination of multiple bare sediment and eelgrass pixels. Fifty-one ground control points were taken August 21, 2014 (the day after aerial imagery was flown) and compared to the final eelgrass delineations for an accuracy assessment.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Results:</SPAN></P><P><SPAN>The eelgrass meadows in the Pugwash estuary comprise ~54% of the estuary with an area of 282ha. The eelgrass is primarily distributed within the basin of the Pugwash estuary, though there are beds extending up into the Pugwash River (south of the main basin). When compared to the ground reference points, there was an 82% accuracy in eelgrass classifications.</SPAN></P></DIV></DIV></DIV>

ShoreZone is a coastal habitat mapping and classification system in which georeferenced aerial imagery is collected specifically for the interpretation and integration of geomorphic and biological features of the intertidal zone and nearshore environment. Oblique low-altitude aerial video and digital still imagery of the coastal zone is collected during the lowest tides of the year, usually from a helicopter flying at or below 100 m altitude. During image collection, the aircraft's GPS position is continuously recorded so that the video and still imagery have positional information. Video imagery is accompanied by continuous, simultaneous commentary by a geologist and a biologist aboard the aircraft. The imagery and commentary are used in the definition of discrete along-shore coastal habitat units and the mapping of observed physical, geomorphic, sedimentary, and biological across-shore components within those units. Units are digitized as shoreline segments in ArcGIS, then integrated with the along-shore and across-shore geological and biological data attribute tables housed in the geodatabase. Mapped habitat features include degree of wave exposure, substrate type, sediment texture, intertidal biota, and some nearshore subtidal biota.</SPAN></P></DIV></DIV></DIV>
