The frequency and severity of wildfires around the world are rising, making the tracking and assessment of wildfire damage a critical issue. However, monitoring these wildfires is made intuitive and seamless with ArcGIS Image for ArcGIS Online<\/a>.<\/p>\n

In Part 2 of this blog series<\/a>, we explored how you can host multidimensional images in ArcGIS Online. Now, in Part 3, we will review a map that shows the impact of a specific fire in a time series. In order to accomplish this, we first needed to create the multidimensional image that will be hosted in ArcGIS Image for ArcGIS Online for this review. If you completed Part 1, then you created that imagery layer. The multidimensional image hosting process is discussed in Part 2, and then visualized in a web map. This blog will cover how to review the multidimensional imagery layer in a time series to see the wildfire in progress.<\/p>\n

This blog is Part 3 of 5 \u2013 collectively, this series will analyze one specific wildfire incident and will cover the following topics:<\/p>\n

    \n
  1. Create multidimensional imagery<\/a><\/li>\n
  2. Host multidimensional imagery layer<\/a><\/li>\n
  3. Review wildfire in time series<\/a><\/li>\n
  4. Host Landsat imagery layers<\/a><\/li>\n
  5. Assess damage<\/a><\/li>\n<\/ol>\n

    Let\u2019s get started!<\/p>\n

    Location<\/h3>\n

    For this study, I chose one of the areas identified as a wildfire hot zone. After some research, the location is around Lac La Valliere near Mistissini, Quebec. In the area southwest of the lake, there is a wildfire that started around June 1, 2023.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2006302,"id":2006302,"title":"LLV_Data","filename":"LLV_Data.png","filesize":463410,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/imagery\/assessing-canadian-wildfire-damage-with-landsat-data-and-arcgis-online\/llv_data","alt":"Lac La Valliere fire location","author":"108651","description":"","caption":"The wildfire location that will be visualized with Landsat data.","name":"llv_data","status":"inherit","uploaded_to":1998082,"date":"2023-06-28 20:59:52","modified":"2023-06-28 21:00:56","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":768,"height":692,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","medium-width":290,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","medium_large-width":768,"medium_large-height":692,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","large-width":768,"large-height":692,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","1536x1536-width":768,"1536x1536-height":692,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","2048x2048-width":768,"2048x2048-height":692,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data-516x465.png","card_image-width":516,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2023\/06\/LLV_Data.png","wide_image-width":768,"wide_image-height":692}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

    Data<\/h3>\n

    A multidimensional tiled imagery layer has been created from the output of Part 1. That imagery layer has all three of the input Landsat images contained in a single imagery layer that can be animated to show the wildfire as it happens. This imagery layer has been hosted in ArcGIS Image for ArcGIS Online.<\/p>\n

    Lac La Valliere multidimensional imagery layer<\/a><\/p>\n

    This multidimensional image show before, during, and after the wildfire strikes the location and can start to tell the story of the damage done to that particular area. Now that you have reviewed the input imagery, you will begin visualizing wildfire damage.<\/p>\n

    Map<\/h3>\n

    A webmap has been created multidimensional imagery layer will allow us to animate the study area and see the damage as it happens. Also included in the webmap are three individual tiled imagery layers that will be used in the next blog for raster analysis.<\/p>\n

    1.<\/strong> Sign into ArcGIS Online<\/strong> and then open this web map<\/a>.<\/p>\n

    Once the webmap opens, take a look at the layers that have been added to the map. There should be the following layers:<\/p>\n
