Description {'en': 'This polygon dataset contains a time series for the spatial extent of eelgrass (Zostera marina) meadows delineated from aerial imagery at several long-term monitoring sites located on the Central Coast of British Columbia. \n\nThe areal extent of eelgrass (Zostera marina) meadows is an important metric for understanding the broader dynamics of eelgrass habitats. Since 2015, the Hakai Geospatial Program has been using remotely piloted aerial systems (RPAS, aka drone) imagery to record change in eelgrass meadow extent at monitoring sites on the Central Coast of BC. Prior to 2015, eelgrass extent at monitoring sites has been conducted using aerial fixed wing aircraft and helicopter imagery and towed underwater video (see 2014 metadata record for eelgrass sites delineated using towed underwater video). Existing methods for mapping eelgrass (e.g. low-tide walking surveys, towed video, or boat-based SCUBA surveys) can be difficult to apply repeatedly and efficiently across large geographic extents. RPASs are portable and efficient tools for mapping nearshore marine environments, such as eelgrass habitat. Despite some limitations of RPAS mapping (e.g. weather, flight time, survey size), RPASs are able to collect high-resolution data (<10 cm) during short windows of opportunity (e.g. low tide).\n\nCore monitoring sites at the Hakai Institute include three eelgrass beds (Pruth Bay, Choked Pass and Koeye) that are mapped annually and three others (Triquet Bay, Goose SW, and McMullin North) which are mapped bi-annually (Fig. 1). Other sites have been mapped advantageously or as part of shorter-term projects and are included in this data package. \n\nFor each site, eelgrass extent was delineated using a combination of object-based image analysis (eCognition Developer 9) and manual delineation within a GIS environment (ArcGIS, v 10.8). In brief, image objects area created via a multiresolution segmentation algorithm within eCognition and the site orthomosaic. These objects are exported to a GIS environment where an analyst classifies objects as eelgrass. The minimum mapping unit for a patch of eelgrass or patch within a bed is 4 m2.', 'fr': "Ce jeu de données polygones contient une série chronologique pour l'étendue spatiale des prairies zostera marina (Zostera marina) délimitées à partir d'images aériennes à plusieurs sites de surveillance à long terme situés sur la côte centrale de la Colombie-Britannique. \n\nL'étendue des prairies de zostera marina est une mesure importante pour comprendre la dynamique plus large des habitats de la zostère. Depuis 2015, le programme géospatial de Hakai utilise des images de systèmes aériens pilotés à distance (RPAS, alias drone) pour enregistrer les changements dans l'étendue des prairies de zostères sur les sites de surveillance de la côte centrale de la Colombie-Britannique. Avant 2015, l'étendue de la zostère sur les sites de surveillance a été réalisée à l'aide d'images aériennes d'avions à voilure fixe et d'hélicoptère et d'une vidéo sous-marine remorquée (voir enregistrement de métadonnées 2014 pour les sites de zostère délimités à l'aide d'une vidéo sous-marine remorquée). Les méthodes existantes de cartographie de la zostère (par exemple, relevés à marée basse, vidéo remorquée ou relevés de plongée sous-marine en bateau) peuvent être difficiles à appliquer de façon répétée et efficace sur de grandes étendues géographiques. Les RPASS sont des outils portables et efficaces pour cartographier les environnements marins littoraux, tels que l'habitat de la zostère. Malgré certaines limitations de la cartographie RPAS (p. ex. météo, temps de vol, taille des relevés), le RPASS est en mesure de collecter des données haute résolution (< 10 cm) pendant de courtes fenêtres d'opportunité (par exemple, marée basse).\n\nLes principaux sites de surveillance de l'Institut Hakai comprennent trois lits de zostère (Pruth Bay, Choked Pass et Koeye) cartographiés chaque année et trois autres (Triquet Bay, Goose SW et McMullin North) qui sont cartographiés deux fois par année (figure 1). D'autres sites ont été cartographiés avantageusement ou dans le cadre de projets à plus court terme et sont inclus dans ce paquet de données. \n\nPour chaque site, l'étendue de la zostère a été délimitée à l'aide d'une combinaison d'analyse d'image basée sur des objets (eCognition Developer 9) et d'une délimitation manuelle dans un environnement SIG (ArcGIS, v 10.8). En bref, les objets d'image sont créés via un algorithme de segmentation multirésolution dans EcoGnition et l'orthomosaïque du site. Ces objets sont exportés vers un environnement SIG où un analyste classe les objets en tant que zostère. L'unité de cartographie minimale pour une parcelle de zostère ou de parcelle dans un lit est de 4 m2."}

</mri:citation> <mri:abstract xsi:type="lan:PT_FreeText_PropertyType"> <gco:CharacterString>This polygon dataset contains a time series for the spatial extent of eelgrass (Zostera marina) meadows delineated from aerial imagery at several long-term monitoring sites located on the Central Coast of British Columbia. The areal extent of eelgrass (Zostera marina) meadows is an important metric for understanding the broader dynamics of eelgrass habitats. Since 2015, the Hakai Geospatial Program has been using remotely piloted aerial systems (RPAS, aka drone) imagery to record change in eelgrass meadow extent at monitoring sites on the Central Coast of BC. Prior to 2015, eelgrass extent at monitoring sites has been conducted using aerial fixed wing aircraft and helicopter imagery and towed underwater video (see 2014 metadata record for eelgrass sites delineated using towed underwater video). Existing methods for mapping eelgrass (e.g. low-tide walking surveys, towed video, or boat-based SCUBA surveys) can be difficult to apply repeatedly and efficiently across large geographic extents. RPASs are portable and efficient tools for mapping nearshore marine environments, such as eelgrass habitat. Despite some limitations of RPAS mapping (e.g. weather, flight time, survey size), RPASs are able to collect high-resolution data (&lt;10 cm) during short windows of opportunity (e.g. low tide). Core monitoring sites at the Hakai Institute include three eelgrass beds (Pruth Bay, Choked Pass and Koeye) that are mapped annually and three others (Triquet Bay, Goose SW, and McMullin North) which are mapped bi-annually (Fig. 1). Other sites have been mapped advantageously or as part of shorter-term projects and are included in this data package. For each site, eelgrass extent was delineated using a combination of object-based image analysis (eCognition Developer 9) and manual delineation within a GIS environment (ArcGIS, v 10.8). In brief, image objects area created via a multiresolution segmentation algorithm within eCognition and the site orthomosaic. These objects are exported to a GIS environment where an analyst classifies objects as eelgrass. The minimum mapping unit for a patch of eelgrass or patch within a bed is 4 m2.</gco:CharacterString> <lan:PT_FreeText> <lan:textGroup> <lan:LocalisedCharacterString locale="#fr">Ce jeu de données polygones contient une série chronologique pour l&#39;étendue spatiale des prairies zostera marina (Zostera marina) délimitées à partir d&#39;images aériennes à plusieurs sites de surveillance à long terme situés sur la côte centrale de la Colombie-Britannique. L&#39;étendue des prairies de zostera marina est une mesure importante pour comprendre la dynamique plus large des habitats de la zostère. Depuis 2015, le programme géospatial de Hakai utilise des images de systèmes aériens pilotés à distance (RPAS, alias drone) pour enregistrer les changements dans l&#39;étendue des prairies de zostères sur les sites de surveillance de la côte centrale de la Colombie-Britannique. Avant 2015, l&#39;étendue de la zostère sur les sites de surveillance a été réalisée à l&#39;aide d&#39;images aériennes d&#39;avions à voilure fixe et d&#39;hélicoptère et d&#39;une vidéo sous-marine remorquée (voir enregistrement de métadonnées 2014 pour les sites de zostère délimités à l&#39;aide d&#39;une vidéo sous-marine remorquée). Les méthodes existantes de cartographie de la zostère (par exemple, relevés à marée basse, vidéo remorquée ou relevés de plongée sous-marine en bateau) peuvent être difficiles à appliquer de façon répétée et efficace sur de grandes étendues géographiques. Les RPASS sont des outils portables et efficaces pour cartographier les environnements marins littoraux, tels que l&#39;habitat de la zostère. Malgré certaines limitations de la cartographie RPAS (p. ex. météo, temps de vol, taille des relevés), le RPASS est en mesure de collecter des données haute résolution (&lt; 10 cm) pendant de courtes fenêtres d&#39;opportunité (par exemple, marée basse). Les principaux sites de surveillance de l&#39;Institut Hakai comprennent trois lits de zostère (Pruth Bay, Choked Pass et Koeye) cartographiés chaque année et trois autres (Triquet Bay, Goose SW et McMullin North) qui sont cartographiés deux fois par année (figure 1). D&#39;autres sites ont été cartographiés avantageusement ou dans le cadre de projets à plus court terme et sont inclus dans ce paquet de données. Pour chaque site, l&#39;étendue de la zostère a été délimitée à l&#39;aide d&#39;une combinaison d&#39;analyse d&#39;image basée sur des objets (eCognition Developer 9) et d&#39;une délimitation manuelle dans un environnement SIG (ArcGIS, v 10.8). En bref, les objets d&#39;image sont créés via un algorithme de segmentation multirésolution dans EcoGnition et l&#39;orthomosaïque du site. Ces objets sont exportés vers un environnement SIG où un analyste classe les objets en tant que zostère. L&#39;unité de cartographie minimale pour une parcelle de zostère ou de parcelle dans un lit est de 4 m2.</lan:LocalisedCharacterString> </lan:textGroup> </lan:PT_FreeText> </mri:abstract> <mri:credit> <gco:CharacterString></gco:CharacterString> </mri:credit> <mri:status> <mcc:MD_ProgressCode codeList="http://standards.iso.org/iso/19115/resources/Codelists/cat/codelists.xml#MD_ProgressCode" codeListValue="completed"></mcc:MD_ProgressCode> </mri:status> <mri:topicCategory> <mri:MD_TopicCategoryCode>oceans</mri:MD_TopicCategoryCode> </mri:topicCategory> <mri:extent> <gex:EX_Extent> <gex:geographicElement> <gex:EX_GeographicBoundingBox> <gex:extentTypeCode> <gco:Boolean>true</gco:Boolean> </gex:extentTypeCode> <gex:westBoundLongitude> <gco:Decimal>-128.65354407</gco:Decimal> </gex:westBoundLongitude> <gex:eastBoundLongitude> <gco:Decimal>-127.69773286</gco:Decimal> </gex:eastBoundLongitude> <gex:southBoundLatitude> <gco:Decimal>51.37817421</gco:Decimal> </gex:southBoundLatitude> <gex:northBoundLatitude> <gco:Decimal>52.1127963</gco:Decimal> </gex:northBoundLatitude> </gex:EX_GeographicBoundingBox> </gex:geographicElement> </gex:EX_Extent> </mri:extent> <mri:extent> <gex:EX_Extent> <gex:verticalElement> <gex:EX_VerticalExtent> <gex:minimumValue> <gco:Real>0.0</gco:Real> </gex:minimumValue> <gex:maximumValue> <gco:Real>0.0</gco:Real> </gex:maximumValue> <gex:verticalCRSId> <mrs:MD_ReferenceSystem> <mrs:referenceSystemIdentifier> <mcc:MD_Identifier> <mcc:code> <gco:CharacterString>5831</gco:CharacterString> </mcc:code> <mcc:codeSpace> <gco:CharacterString>EPSG</gco:CharacterString> </mcc:codeSpace> <mcc:version> <gco:CharacterString>2012-08-10</gco:CharacterString> </mcc:version> <mcc:description> <gco:CharacterString>EPSG::5831 - Instantaneous Water Level depth - Depth relative to instantaneous water level uncorrected for tide.
