Canadian Drought Monitor This series of datasets has been created by AAFC’s National Agroclimate Information Service (NAIS) of the Agro-Climate, Geomatics and Earth Observations (ACGEO) Division of the Science and Technology Branch. The CDM is a composite product developed from a wide assortment of information such as the Normalized Difference Vegetation Index (NDVI), streamflow values, Palmer Drought Index, and drought indicators used by the agriculture, forest and water management sectors. Drought prone regions are analyzed based on precipitation, temperature, drought model index maps, and climate data and are interpreted by federal, provincial and academic scientists. Once a consensus is reached, a monthly map showing drought designations for Canada is digitized. AAFC’s National Agroclimate Information Service (NAIS) updates this dataset on a monthly basis, usually by the 10th of every month to correspond to the end of the previous month, and subsequent Canadian input into the larger North American Drought Monitor (NA-DM). The drought areas are classified as follows: D0 (Abnormally Dry) – represents an event that occurs once every 3-5 years; D1 (Moderate Drought) – represents an event that occurs every 5-10 years; D2 (Severe Drought) – represents an event that occurs every 10-20 years; D3 (Extreme Drought) – represents an event that occurs every 20-25 years; and D4 (Exceptional Drought) – represents an event that occurs every 50 years. Impact lines highlight areas that have been physically impacted by drought. Impact labels specify the longitude and magnitude of impacts. The impact labels are classified as follows: S – Short-Term, typically less than 6 months (e.g. agriculture, grasslands). L – Long-Term, typically more than 6 months (e.g. hydrology, ecology). 2014-12-09 2017-09-15 Agriculture and Agri-Food Canada agri-geomatics-agrog@agr.gc.ca Nature and EnvironmentScience and TechnologyClimateDroughtPrecipitation Pre-packaged MapsPDF http://www.agr.gc.ca/atlas/maps_cartes/canadianDroughtMonitor/en/ Pre-packaged MapsPDF http://www.agr.gc.ca/atlas/maps_cartes/canadianDroughtMonitor/fr/ Pre-packaged FGDB filesFGDB/GDB http://www.agr.gc.ca/atlas/data_donnees/cli/canadianDroughtMonitor/fgdb/ Pre-packaged SHAPE filesSHP http://www.agr.gc.ca/atlas/data_donnees/cli/canadianDroughtMonitor/shp/ Pre-packaged GML filesGML http://www.agr.gc.ca/atlas/data_donnees/cli/canadianDroughtMonitor/gml/ Data Product SpecificationPDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/canadianDroughtMonitor/en/ISO_19131_Canadian_Drought_Monitor_Data_Product_Specification.pdf Data Product SpecificationPDF http://www.agr.gc.ca/atlas/supportdocument_documentdesupport/canadianDroughtMonitor/fr/Outil_de_surveillance_des_secheresses_au_Canada_ISO_19131_.pdf Monthly Areas of Drought in CanadaWMS http://www.agr.gc.ca/atlas/services/mapservices/aafc_canadian_drought_monitor/MapServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png&feature_info_type=text/html Monthly Areas of Drought in CanadaWMS http://www.agr.gc.ca/atlas/services/servicesdecarte/aac_surveillance_des_secheresses_au_canada/MapServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png&feature_info_type=text/html Monthly Areas of Drought in Canada (AGOL)ESRI REST http://www.arcgis.com/home/item.html?id=8bedc241568649d39932c4faa9303f32 Monthly Areas of Drought in Canada (AGOL)ESRI REST http://www.arcgis.com/home/item.html?id=a4319647bebc4de5be195e446fbd84b3 Canadian Drought MonitorHTML http://www.agr.gc.ca/atlas/cdm Canadian Drought MonitorHTML http://www.agr.gc.ca/atlas/ssc Monthly Areas of Drought in CanadaESRI REST http://www.agr.gc.ca/atlas/rest/services/mapservices/aafc_canadian_drought_monitor/MapServer Monthly Areas of Drought in CanadaESRI REST http://www.agr.gc.ca/atlas/rest/services/servicesdecarte/aac_surveillance_des_secheresses_au_canada/MapServer

Is there any data in csv format that has percentages of the area that are in D0, D1, etc. instead of just the maps? Something like http://droughtmonitor.unl.edu/Data/DataTables.aspx

Hello, Thank you for your comment. I have sent your inquiry to the data owner for their response. Stay tuned! Momin The Open Government team

Sooooo. Where's the historical map data?

Hi Keith, Thank you for your comment, I have sent your request off to the dataset holder for clarification. Have a nice day, Sabrina Open Government Team

Hi there - here is the response I received from the data holder: We do have historical map data with http://open.canada.ca/data/en/dataset/292646cd-619f-4200-afb1-8b2c52f984a2. On the resources list, you can use the gml, shp or fgdb formats. For example, with the gml format, the Areas of Drought data goes back to 2002. As Impact Lines and Impact Labels have only been recently collected, the data is from 2015 and onward. As well, there are static maps available, web services and a web application. For example, if you go into the Application, they can see the data from 2002 to 2016. There are also 3 other sub-datasets available: Areas of Drought in Canada - http://open.canada.ca/data/en/dataset/90d3f93c-662a-4aed-ae3a-26d7e74c0af5 Impact Labels - http://open.canada.ca/data/en/dataset/0ca50b6f-6a9d-4ca8-8a0c-589d5bde19ae Impact Lines - http://open.canada.ca/data/en/dataset/43ed6d12-afa8-4013-9464-d0632a5272c6 I hope this helps.
