Map data and credits

Castabout’s maps and figures come from open data and licensed services. The map shows the credits its licences require (© OpenStreetMap, and Powered by Esri on Satellite); this page lists every source, with its licence.

Castabout is an independent app. It is not affiliated with any government agency and does not represent one. Seasons, rules, readings and access in the app are information to help you plan: always check the sources below before you fish.

Base maps

• Topo is drawn from the Protomaps basemap, built from OpenStreetMap data. © OpenStreetMap contributors, available under the Open Database License. Castabout serves Australian and Canadian extracts from its own tile server, restyled in its own colours.
• Hillshade and 3D terrain come from Terrain Tiles (Mapzen/Tilezen, on AWS Open Data). For Australia these include SRTM and GMTED2010 terrain data courtesy of the U.S. Geological Survey, ETOPO1 terrain data from the U.S. National Oceanic and Atmospheric Administration, and terrain data © Commonwealth of Australia (Geoscience Australia) 2017, CC BY 4.0. Full list: Tilezen attribution.
• Satellite imagery is Esri World Imagery, powered by Esri. Source: Esri, Vantor, GeoEye, Earthstar Geographics, CNES/Airbus DS, USDA, USGS, AeroGRID, IGN, and the GIS User Community. It’s also used for the satellite pictures on water cards and pages, which are credited “Imagery: Esri”. Labels, roads and water lines on top come from Protomaps and OpenStreetMap.
• Map labels use Noto Sans, under the SIL Open Font License, from Protomaps’ basemap assets.

Waters, reaches and lakes

• River, reach and lake shapes come from the Australian Hydrological Geospatial Fabric (Geofabric), Bureau of Meteorology, © Commonwealth of Australia. Licensed from the Commonwealth of Australia under a Creative Commons Attribution 4.0 International licence. Castabout has changed them: filtered to the waters it covers, joined per water and reach, simplified, and rounded.
• Canadian stream shapes come from the Freshwater Atlas Stream Network, Province of British Columbia. Contains information licensed under the Open Government Licence – British Columbia. Castabout joins segments by their provincial water identifier and removes the elevation ordinate for display. Historical fish records come from Fish Observations — Public, Province of British Columbia, under the same licence; each water page links its sources.
• Access routes (walking tracks, 4WD tracks and minor roads) are OpenStreetMap paths and roads from the Protomaps basemap. They show where a track is mapped, not whether you may use it: check access, gates and land tenure before you go.
• Access points come from the state and territory access datasets named on each place’s page.

Fish records

• Species records come from the Atlas of Living Australia and the datasets it aggregates; each water page names the datasets and licences behind its records. Canadian records come from Province of British Columbia data (above) and the Freshwater Fisheries Society of BC.

Conditions and seasons

• River flows, levels and temperatures come from Bureau of Meteorology Water Data Online, © Commonwealth of Australia, CC BY 4.0. Each gauge’s data belongs to the organisation that runs it, and that owner’s credit appears under the reading.
• Weather forecasts and sunrise, sunset and moon times are based on data from MET Norway (the Norwegian Meteorological Institute), Locationforecast and Sunrise APIs, CC BY 4.0. Castabout shows them in your units and the water’s time zone. Castabout is not made or endorsed by MET Norway or Yr.
• Seasons and rules are summaries of each state’s and territory’s published rules. Each links to its source. The rules themselves are the source, not Castabout.
