AIS was developed for safety/collision-avoidance. Global Fishing Watch analyzes AIS data collected from vessels that our research has identified as known or possible commercial fishing vessels, and applies a fishing presence algorithm to determine “apparent fishing activity” based on changes in vessel speed and direction. The algorithm classifies each AIS broadcast data point for these vessels as either apparently fishing or not fishing and shows the former on the Global Fishing Watch fishing activity heat map. AIS data as broadcast may vary in completeness, accuracy and quality. Also, data collection by satellite or terrestrial receivers may introduce errors through missing or inaccurate data. Global Fishing Watch’s fishing presence algorithm is a best effort mathematically to identify “apparent fishing activity.” As a result, it is possible that some fishing activity is not identified as such by Global Fishing Watch; conversely, Global Fishing Watch may show apparent fishing activity where fishing is not actually taking place. For these reasons, Global Fishing Watch qualifies designations of vessel fishing activity, including synonyms of the term “fishing activity,” such as “fishing” or “fishing effort,” as “apparent,” rather than certain. Any/all Global Fishing Watch information about “apparent fishing activity” should be considered an estimate and must be relied upon solely at your own risk. Global Fishing Watch is taking steps to make sure fishing activity designations are as accurate as possible. Global Fishing Watch fishing presence algorithms are developed and tested using actual fishing event data collected by observers, combined with expert analysis of vessel movement data resulting in the manual classification of thousands of known fishing events. Global Fishing Watch also collaborates extensively with academic researchers through our research program to share fishing activity classification data and automated classification techniques.   Filters:  timestamp >= '2023-01-01T00:00:00.000Z' and timestamp <= '2024-01-01T00:00:00.000Z' Resolution: high (100th degree resolution)   ### Format - GeoTIFF - CRS: EPSG:4326 - WGS 84 - Geographic   ### License Unless otherwise stated, Global Fishing Watch data is licensed under a [Creative Commons Attribution-ShareALike 4.0 International license](https://creativecommons.org/licenses/by-sa/4.0/) and code under an [Apache 2.0 license](http://www.apache.org/licenses/LICENSE-2.0).   completed bellaisaatwork@gmail.com originator https://geoplatform.tools4msp.eu/uploaded/thumbs/layer-63f2228d-b513-4c22-a957-d4abd37a2023-thumb-8b3eade2-3e27-44b0-90bc-f5d7b8d9ff86.png?v=841d110e Thumbnail for 'GFW Fishing Effort Total 2023' image/png ESRI Shapefile 1.0 MSP Italy fishing gfw theme MSP_Italy Tools4msp 2023-05-17 pubblicazione Italy place license Not Specified: The original author did not specify a license. limitation not listed eng utf8 fishing 6.1850000000000005 18.945 35.144999999999996 45.794999999999995 2020-01-01T16:43:00+00:00 2021-01-01T16:43:00+00:00 No information provided image https://geoplatform.tools4msp.eu/layers/public_global_fishing_effort_v20231026:geonode:public_global_fishing_effort_v20231026 WWW:LINK-1.0-http--link Online link to the 'GFW Fishing Effort Total 2023' description on GeoNode https://geoplatform.tools4msp.eu/uploaded/thumbs/layer-63f2228d-b513-4c22-a957-d4abd37a2023-thumb-8b3eade2-3e27-44b0-90bc-f5d7b8d9ff86.png WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.png GFW Fishing Effort Total 2023 (Thumbnail Format) https://geoplatform.tools4msp.eu/download/928 WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.zip GFW Fishing Effort Total 2023 (Original Layer Format) https://geoplatform.tools4msp.eu/geoserver/ows?service=WMS&request=GetMap&layers=geonode%3Apublic_global_fishing_effort_v20231026&format=image%2Fjpeg&height=550&width=550&srs=EPSG%3A4326&bbox=6.1850000%2C35.1450000%2C18.9450000%2C45.7950000 WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.jpg GFW Fishing Effort Total 2023 (JPEG Format) https://geoplatform.tools4msp.eu/geoserver/ows?service=WMS&request=GetLegendGraphic&format=image/png&WIDTH=20&HEIGHT=20&LAYER=geonode:public_global_fishing_effort_v20231026&STYLE=public_global_fishing_effort_v20231026&version=1.3.0&sld_version=1.1.0&legend_options=fontAntiAliasing:true;fontSize:12;forceLabels:on WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.png GFW Fishing Effort Total 2023 (Legend Format) https://geoplatform.tools4msp.eu/geoserver/ows?service=WMS&request=GetMap&layers=geonode%3Apublic_global_fishing_effort_v20231026&format=application%2Fpdf&height=550&width=550&srs=EPSG%3A4326&bbox=6.1850000%2C35.1450000%2C18.9450000%2C45.7950000 WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.pdf GFW Fishing Effort Total 2023 (PDF Format) https://geoplatform.tools4msp.eu/geoserver/ows?service=WMS&request=GetMap&layers=geonode%3Apublic_global_fishing_effort_v20231026&format=image%2Fpng&height=550&width=550&srs=EPSG%3A4326&bbox=6.1850000%2C35.1450000%2C18.9450000%2C45.7950000 WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.png GFW Fishing Effort Total 2023 (PNG Format) https://geoplatform.tools4msp.eu/geoserver/ows?service=WCS&request=GetCoverage&coverageid=geonode__public_global_fishing_effort_v20231026&format=image%2Ftiff&version=2.0.1&compression=DEFLATE&tileWidth=512&tileHeight=512 WWW:DOWNLOAD-1.0-http--download public_global_fishing_effort_v20231026.geotiff GFW Fishing Effort Total 2023 (GeoTIFF Format) https://geoplatform.tools4msp.eu/geoserver/ows OGC:WMS geonode:public_global_fishing_effort_v20231026 geonode Service - Provides Layer: GFW Fishing Effort Total 2023 https://geoplatform.tools4msp.eu/geoserver/ows OGC:WCS geonode:public_global_fishing_effort_v20231026 geonode Service - Provides Layer: GFW Fishing Effort Total 2023 dataset
