Here's how to create a custom basemap from the archives.","flexible_content":[{"acf_fc_layout":"content","content":"

The World Imagery basemap is updated regularly with newer imagery. When and where updates occur, the previous imagery is replaced and is no longer visible. In the vast majority of cases the updated imagery is better, more recent, and is preferred, but there may be exceptions. For example, the previous imagery may better align with your GIS layers, or may offer fewer clouds or snow cover. Wayback will allow you to use the version of World Imagery that best suits your needs.<\/p>\n

There are two options if you prefer to use imagery from a previous date.<\/p>\n

Option 1<\/strong> – Create a map using the Wayback app with the previous vintage imagery as the basemap. This allows you to use the imagery when desired, keeping your organization’s basemap gallery as-is.<\/p>\n

Option 2<\/strong> – Create a map using the Wayback app to include in a custom basemap gallery, allowing use of the Wayback imagery throughout your organization and allowing you to combine current Esri basemaps with your preferred version of World Imagery.<\/p>\n

The process of creating a map is exactly the same for both options, the only difference with the second option is that you will add the map to a custom basemap group that your organization will use.<\/p>\n

Tip<\/strong>: In addition to using the Wayback app, there is a third option. There is an ArcGIS Online item for every archived version of imagery which you can find in the Wayback Imagery group<\/a>. If you already know which version of the imagery you want to use, you can locate it in the group and create a map directly from the item.<\/p>\n

All of these workflows are detailed below.<\/p>\n"},{"acf_fc_layout":"content","content":"

Weather happens<\/h2>\n

We’ve often admired and pondered clouds\u2014those fascinating and dynamic suspensions of tiny water droplets or ice crystals that bring rain to parched land and complement any day by making for colorful sunsets. But if we are interested in viewing details on the Earth\u2019s surface using satellite imagery, clouds or snow can hide what we want to see, and in quantity can be an impediment to using the imagery effectively.<\/p>\n

While relatively rare, with any update to the World Imagery basemap clouds or other weather events could potentially be introduced in your specific area of interest. The example below shows an area with cloud cover after an update on the left, and the previous imagery on the right.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":652142,"id":652142,"title":"wb-1s","filename":"wb-1s.jpg","filesize":37085,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/wayback-custom-basemap\/wb-1s","alt":"Imagery with clouds and clear","author":"7641","description":"","caption":"View larger image","name":"wb-1s","status":"inherit","uploaded_to":606162,"date":"2019-11-07 23:32:26","modified":"2020-04-08 19:34:28","menu_order":0,"mime_type":"image\/jpeg","type":"image","subtype":"jpeg","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":750,"height":209,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s-213x200.jpg","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","medium-width":464,"medium-height":129,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","medium_large-width":750,"medium_large-height":209,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","large-width":750,"large-height":209,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","1536x1536-width":750,"1536x1536-height":209,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","2048x2048-width":750,"2048x2048-height":209,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","card_image-width":750,"card_image-height":209,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1s.jpg","wide_image-width":750,"wide_image-height":209}},"image_position":"left-center","orientation":"horizontal","hyperlink":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/11\/wb-1.jpg"},{"acf_fc_layout":"content","content":"

Going back in time with Wayback<\/h2>\n

Wayback imagery<\/strong> is a digital archive of the World Imagery basemap, enabling users to access more than 150 different versions of World Imagery captured over the past 8 years. Each record in the archive represents a version of World Imagery as it existed on the date it was published.<\/p>\n

The Wayback app<\/strong> offers an interactive way to browse the imagery archives and view local changes. The app currently provides access to all published versions of World Imagery, dating back to February 20, 2014.<\/p>\n"},{"acf_fc_layout":"content","content":"

Make a map using the Wayback app<\/h2>\n

To make a map using a specific version of Wayback imagery, follow these steps.<\/p>\n

Step 1<\/strong> \u2014 Open the Wayback app<\/a>.<\/p>\n

You can find the app by searching ArcGIS Online, or can open the app from the Living Atlas website where you will find it on the Apps tab and also via the Browse tab.<\/p>\n
