The basemap imagery comes from a variety of sources at a range of resolutions\u2014in all, over 80 different versions of the basemap are available.\r\n\r\nThis is useful because when you view imagery basemaps, you typically only see the most recent images. However, sometimes it is a previous version of the basemap that you really want to see or use for a project. For example, maybe you need to use a particular version of basemap imagery for a long-term project, or you need to digitize features using a specific update of the basemap imagery. The World Imagery Wayback archive has been developed to meet just such demands.\r\n\r\nImagery in the archive can also help provide records of landscapes and, in some cases, show change over time. For example, visual analysis of archived imagery can help to identify where glaciers have shrunk; where urban areas have grown; and where change has occurred on the terrain due to volcanic activity, mudslides, or earthquakes.\r\n\r\nLike other content in\u00a0<a href=\"https:\/\/www.arcgis.com\/index.html\">ArcGIS Online<\/a>, you can access the archived images from ArcGIS Online,\u00a0<a href=\"https:\/\/www.esri.com\/en-us\/arcgis\/products\/arcgis-pro\/overview\">ArcGIS Pro<\/a>\u00a0or ArcMap, making the images especially useful. If you already know which images you want to use, you can simply search for them in the\u00a0<a href=\"http:\/\/esri.maps.arcgis.com\/home\/group.html?id=0f3189e1d1414edfad860b697b7d8311&amp;start=1&amp;view=list#content\">Wayback Imagery<\/a>\u00a0group in ArcGIS Online, or you can find them through a Catalog\u00a0<a href=\"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-living-atlas\/imagery\/wayback-server-connection-in-pro\/\">connection to the imagery server<\/a>\u00a0in ArcGIS Pro or ArcMap. If you are not sure which images you want to use or you just want to explore the possibilities, use the\u00a0<a href=\"https:\/\/livingatlas.arcgis.com\/wayback\/\">World Imagery Wayback app<\/a>.\r\n\r\n<img src=\"https:\/\/www.esri.com\/about\/newsroom\/app\/uploads\/2018\/09\/wayback1.jpg\" \/>\r\n\r\nIn this tip, you will learn how to use World Imagery Wayback to explore changes in the Aral Sea, once the fourth largest lake in the world. Using archived imagery, you will be able to see how the lake has diminished in size due to water diversion projects aimed at transforming deserts in Kazakhstan, Uzbekistan, and Turkmenistan into farms.\r\n\r\nYou will learn how to find the images you want by using the World Imagery Wayback app, which can be accessed online from the Living Atlas. You will add the images to a web map in ArcGIS Online and then share the web map using the\u00a0<a href=\"https:\/\/storymaps.arcgis.com\/en\/app-list\/swipe-spyglass\/\">Esri Story Map Swipe<\/a>\u00a0app.\r\n\r\nThe Esri World Imagery Wayback app automatically opens to display an area near Las Vegas, Nevada, which has undergone rapid urban growth over the past five years.\r\n<h2>Find the images of interest using the World Imagery Wayback app<\/h2>\r\n<ol class=\"start\">\r\n \t<li style=\"list-style-type: none;\">\r\n<ol class=\"start\">\r\n \t<li>Open the\u00a0<a href=\"https:\/\/livingatlas.arcgis.com\/wayback\/\">World Imagery Wayback app<\/a>.<\/li>\r\n \t<li>In the search box at the upper right of the map view, type the name of your area of interest.
