A geographic information system of Sea Lion Island, Falkland Islands, Falkland Islands (1995-2019)

The goal of the project is to create a geographic information system to provide a centralized storage for ppatially referenced data collected at Sea Lion Island, that will include marine mammals (pinnipeds and cetaceans), bird species, topography (e.g,, beach profiles) and landscape imagery (e.g., drone images). Information from other sources will be adde, in particular data and maps collected during spot surveys carried out in the past, that have been recovered from various sources. These data include general surveys of plants and birds, surveys of single species (e.g., caracara), and opportunistic counts and observations of sea lions, seals, and cetaceans. Further information is available on the research group website, www.eleseal.org.

Lineage At Sea Lion Island, spatially referenced data using various devices, with variable level of accuracy, have been collected since 1995 and includes: 1) navigation grade GPS receivers (Garmin GPSMap); 2) survey grade GPS receivers (Magellan ProMark3); 3) high precision laser telemetry systems (Leica Laser Locator, Disto S910); 4) navigation grade GPS loggers (Canmore); 5) semi-professional UAVs (Phantom III and Mavic, DJI). All these instruments produce data which are downloaded using different protocols and saved in different formant. However, all data are processed using customs script and converted in a common CSV format. From CSV file, shapefiles are routinely generated and then imported as layers of a single QGIS project. Data quality control and checking is done first on the original CSV file, and then again on the shapefiles imported in QGIS. We are currently considering the migration of the system form individual shapefiles to SpatiaLite database.

Accuracy Accuracy of mapping by navigation grade GPS is 5 metres. accuracy of mapping by survey grade GPS receivers is submetric to decimetric. accuracy of mapping by laser telemetry (Leica Laser Locator and Leica Disto S910) is between 0.5 and 1 meter. Tracing of spatial features is carried out in QGIS using high resolution satellite imagery as reference layer.
