Annual Crop Inventory Understanding the state and trends in agriculture production is essential to combat both short-term and long-term threats to stable and reliable access to food for all, and to ensure a profitable agricultural sector. Starting in 2009, the Earth Observation Team of the Science and Technology Branch (STB) at Agriculture and Agri-Food Canada (AAFC) began the process of generating annual crop type digital maps. Focusing on the Prairie Provinces in 2009 and 2010, a Decision Tree (DT) based methodology was applied using optical (Landsat-5, AWiFS, DMC) and radar (Radarsat-2) based satellite images. Beginning with the 2011 growing season, this activity has been extended to other provinces in support of a national crop inventory. To date this approach can consistently deliver a crop inventory that meets the overall target accuracy of at least 85% at a final spatial resolution of 30m (56m in 2009 and 2010). 2013-11-04

Hi, I was wondering approximately what month the annual crop inventory covers are classified from the radarsat scenes. I am looking at the 2011 in particular. This information was not provided in the metadata. Thanks

Hi Farah, thank you for your comment. Your inquiry has been forwarded to the data owner for their response. Regards, Momin, the Open Government team.

Farah - below is the response we received from the data owner: “There is no single answer. The crop inventory uses multi-temporal RADARSAT-2 imagery from different dates in the growing season. And because of the way the satellite overpasses, acquisitions happen on different dates. We usually try to obtain a monthly coverage from May through September, though as mentioned above dates vary.” I hope this helps. Momin, the Open Government team.

Yes, thank you!

Great data, we are overlaying this data with our neonicotinoid water monitoring data.

Hi Charlotte, thanks for your feedback, we are glad that you find this data useful! Best of luck with your project! Momin, the Open Government team.

Fantastic dataset! Thanks for all the work that goes into it. Question: How is it determined when to include natural/semi-natural cover types (or any non-agricultural covers) as classes in the ACI? In other words, what criteria is used to identify cover types as being either associated with agriculture or excluded from the agricultural extent?

Hi Sara, The following comment has been posted on behalf of the data owner: "The agricultural extent of Canada is a standard base layer used by AAFC and the Government of Canada to delineate the extent of Canada’s agricultural areas. The extent is not determined by the creators of the crop inventory; rather, they use it as the limits to which they map. The crop inventory is mapped for everything inside the agricultural extent. Crop classes are mapped to varying detail, depending on whether validation statistics indicate good mapping accuracies. Where detailed mapped classes show lower mapping accuracies, these classes are aggregated to form a more general class, with a higher and more acceptable accuracy. As for non-crop classes, we map everything that is not agriculture, but to a more general degree. For example, instead of detailed forest classes, forest is simply mapped as deciduous or coniferous. The same goes for other classes. This is text from one of our reports: The thematic classes used during the crop classification process can vary from application to application and from nation to nation. This is problematic because these incompatibilities hamper the aggregation toward broader regional and global datasets. As a result, the classes used for crop identification and mapping are usually based on national or international classification schemes that provide the best semantic interoperability with other land cover classifications and facilitate direct classification-to-classification comparisons. To this end, the AAFC Annual Crop Inventory uses a harmonized legend based on The Canadian Forest Service (CFS) Earth Observation for Sustainable Development (EOSD) Land Cover Classification (Wulder and Nelson, 2001). This legend is compatible with a number of internationally-recognized legends, including the Land Cover Classification System (LCCS) of the United Nations (UN) Food and Agriculture Organization (FAO) (Di Gregorio and Jansen, 2000) Wulder, M.A., and Nelson, T. (2001). EOSD Land Cover Classification Legend Report (Government of Canada). Di Gregorio, A., and Jansen, L.J.M. (2000). Land cover classification system: LCCS : classification concepts and user manual (Rome: Food and Agriculture Organization of the United Nations). Arguably every class within the ag extent is associated with agriculture. For example, it is important to know whether wetland or forest surround fields or whether it is grassland for example. However, these natural cover classes are not crops, and are thus mapped more generally." Thanks and hope this is helpful, Tasha, the Open Government Team

When does the AAFC Annual Crop Inventory get released every year (month) as it is not listed in the metadata?

Love this product -- so many uses! Just wondering what the estimated completion date is for the 2015 crop year dataset? Thank you.

Hi Markus, The data owner informs us that the 2015 dataset was completed on April 8 2016. Glad to hear to like the product! Thom for the Open Government Team

Hi there, I also experienced corrupt file issues. Tried both pix and geotiff files for ON 2015 and neither would load in ArcGIS or QGIS.

Hi Colin, Thank you for flagging this. I have sent this to the data owner for action. -Tasha, the Open Government Team

Hi Colin, The following has been posted on behalf of the data owner: The file in question downloads file, extracts from the zip file fine and draws in ArcGIS as expected.. this could be an error in the download or if you have not correctly added the dataset to ArcMap. Thanks and hope this helps, Tasha, the Open Government Team

Thanks for making this data available! Do you know approximately when the 2015 dataset will be released?

Thanks for your comment. We will look into that and get back to you. The Open Government Team

I am also interested in when the 2015 data for the prairie (western) provinces will be released (I see that it is available for the eastern provinces now). Thank you!

We've sent your question to the data owners and will get back to you as soon as possible. Thank you! The Open Government Team

We have this response from the data steward. 1. The 2015 AB crop inventory release will be a bit later this year. It is hard to mention a specific date as we are waiting for ground data from an external source (the AB crop insurance corporation). Once we have the data, we can process the whole provinces within a few days. 2. Unfortunately, for now, release dates are not consistent from one year to the other. For many provinces, including AB, we are dependent on external agency to get ground information. The dates they provides us with the data will vary a lot. We are in communication with them to improve that aspect as we would like in the future to publish our maps soon after the growing season or even within the growing season. 3. We are measuring the crop classification accuracy for each province every year. In the metadata, you will find the overall crop accuracy per province. We also produce crop confusion matrix, producer and user accuracies per crop, Kappa coefficients. If you want that information, please contact us directly (Thierry.fisette@agr.gc.ca or Patrick.Rollin@agr.gc.ca)." The Open Government Team

Will the 2014 inventory have the UTM zone versions available soon? Transforming from WGS84 to NAD83 distorts the output cells in GIS and hoping the data will be available in UTM zones soon (same PCI approach as before?). As FYI, the provincial WGS projections also differ year-to-year (Albers in 2014 vs. Lambert in 2013) although I realize the difference is minimal near USA border.

Thanks for your question. Agriculture and Agri-Food Canada has provided the following response: "It had become increasingly difficult for us to manage two versions of the map, so it was decided for the 2014 Crop Map that we would drop the UTM version and only continue with the provincial file (which will continue to be Albers from now on)." The Open-ouvert team

I would like to download shapefiles (I can only assume that the ESRI REST format is what I'm looking for--though there is no explanation of this REST acronym in the Data Product Specifications). However, every 'download button' leads to the same error message ``Error handling service request : Could not find a service with the name 'imageservices/ImageServer/aafc_crop_inventory_2014_30m' in the configured clusters. Service may be stopped or ArcGIS Server may not be running.`` I've attempted to download from multiple computers, with no change to the situation. Please help!!

Hi Mary, We will look into that right away and get back to you. The Open Government Team

Hi Mary, Here is the response from the data owner, hope this helps. ESRI REST is not a Shapefile but an mapping service, similar to an OGC WMS. Currently Open Data officially recognizes WMS as a format type but not REST or ArcGIS online items. The Annual Crop Inventory is a raster dataset so no shapefiles have been produced or will be produced for this dataset. If you look at the Resources associated with this dataset, the first one is of format Tiff. If you cannot use the services, then downloading the tiffs are your best bet.

This is a great dataset! Thank you for putting it together! Question: The maps have 'wheat' as well as 'spring wheat' and 'winter wheat' classes. Does the 'wheat' class (typically) refer to spring or winder wheat? Thanks!

Thank you for your comment. The following response has been posted on behalf of the data owner : "The wheat class (140) is only mapped when it is not possible to differentiate between spring wheat (146) and winter wheat (145). If wheat (140) is mapped then it could include either spring or winter wheat or it could be both spring and winter wheat"

When can I expect 2014 data to be published? Thank you.

Thank you for your comment. The following response has been posted on behalf of the data owner : "The 2014 product is currently be reviewed and is targeted for release March 31, 2015." Thank you.

I downloaded the 2013 UTM17 data but it appears to be continuous data rather than thematic like all the rest of the 2013 UTM files. (AAFC_CI_2013_UTM17_30m_v1_TIF.zip 06-Mar-2014 11:35 41M)

Thank you for your comment. The following response has been posted on behalf of the data owner : "We cannot replicate the issue. The data is thematic and while querying the actual pixel value – the results fall in the expected range". If you are still experiencing issues, please email us directly at open-ouvert@tbs-sct.gc.ca

How can i find the crop growing region file(in ArcGIS format)? I only focus on the crop land, so it is helpful that accurate crop growing region can be provided.

Download links are not currently working.

Thank you for your comment. The server had been down. It is now up and running, and the links should working properly now. Let us know if you experience any issues.

The majority of the .tif files appear corrupted and will not import into Google Earth Pro.

Hi Jeff, thank you for your comment. The following response has been posted on behalf of the data owners. "We looked at the 2013 batch of images. They are delivered in both a Provincial or UTM cut. Both versions opened in ArcMAP and were geographically correct. We also opened the images in Windows Photo Viewer. For some images Windows Photo Viewer ran out of memory. For the UTM version the SME did use a non standard datum in some cases and we are investigating why. If you can specify which images specifically you think are corrupt we can do a more intensive investigation. Otherwise I think there are likely limitations in Google Earth Pro. We have a web application that you could use: http://www.agr.gc.ca/atlas/agpv?webmap=1ce0fd28f27149c6a44d23a69a760cd6 that shows the crop inventory from 2009 to 2013 he can even add his own shapefiles of map services to the map. We will also be working on a WMS for the public in the near future". Thank you.

How would I cite the Agriculture and Agri-Food Canada Crop Inventory 2009 (AAFC_Prairie_Crop_Mapping_2009_v3.tif) for publication?

Thank you for your question. You may wish to consult the specifc citation standard you would like to use; however, we would advise you to take a look at : http://www.dcc.ac.uk/resources/how-guides/cite-datasets Thank you, Data.gc.ca

While AAFC would like to respond to the above comment, it is extremely difficult to do so given the lack of information provided. The Crop Inventory is a highly validated product, and our target accuracies of 85% are often maintained (see metadata of product for details; an 85% accuracy means, on average, 85 fields of 100 will be accurately classified). Indeed, the high quality of these data have been recognized by users from other Government Departments, the Provinces, and the private sector. That said, we do recognize that there will be areas where the classification is worse than that desired and we encourage users of these data to send detailed information back to AAFC in order for us to investigate any problems and make our product better.

Thank you for your feedback. We have forwarded your comment to the dataset provider for their response.
