ArcGIS Wayback makes it possible to query World Imagery, ESRI's free service, from different time levels. Thus, the image data of a specific area can be used, for example, to analyze spatial changes in the environment. World Imagery is freely available as a WMTS service and can therefore also be integrated into your WebOffice 10.9 R4 project. The following section explains step by step how ArcGIS Wayback can be implemented in your WebOffice 10.9 R4 project.

 

Step one: Determine WMTS URL for the desired layer

The general URL for the World Imagery WMTS service is: https://wayback.maptiles.arcgis.com/arcgis/rest/services/world_imagery/mapserver/wmts/1.0.0/wmtscapabilities.xml

In order to obtain the image data that represent the desired points in time, the corresponding identifier must be added at the end of the URL. The best way to determine the complete URL is to add the WMTS service (1) to ArcCatalog, enter the above URL (2) and use the Get Layers button (3) to list the available layers. After selecting the respective layer from the list, the corresponding identifier is displayed in the window next to it (4). Finally, this identifier has to be added to the general URL with the addition ?layer=.

The example URL, which would result from the screenshot, is thus:

https://wayback.maptiles.arcgis.com/arcgis/rest/services/world_imagery/mapserver/wmts/1.0.0/wmtscapabilities.xml?layer=WB_2014_R06

 

 

Step two: Add WMTS map service to project

In the next step, the determined URL is used to add the WMTS service to the WebOffice 10.9 R4 project. To do this, an OGC map service (WMTS) is added to the context menu of the map collection and the URL is entered in the Server parameter. This process is repeated with each additional layer of the World Imagery service.

 

 

 

Step three: Create map views

To be able to compare the added WMTS layers in the WebOffice 10.9 R4 project, a separate map view must be configured for each added service. For this purpose, a new map view is configured in the context menu of the map views, to which a reference to map service of map collection is added. For the Related Map Service parameter, one of the previously added services is selected.
