Planet imagery refers to images acquired by Planet’s SkySat, PlanetScope & RapidEye constellations. It also includes open imagery archives like images acquired from LandSat & Sentinel satellites.
The search, stream and download capabilities for Planet imagery are organized in the Planet Imagery Search Panel in ArcGIS that can be pulled up by selecting the Image Search icon from the Planet Imagery ribbon.
Search for Imagery
To search for imagery, the only required field is an area of interest (aoi), or alternatively a specific Image ID. On the Planet Imagery Search Panel there are multiple options for selecting an area of interest: e.g., selecting the current map extent, the extent of all active layers in your Pro map, drawing a specific area of interest, or using a selected feature to define a polygon aoi.
Once an area of interest has been set, you can directly search for Planet imagery within ArcGIS. To further refine your search results, select the “Filter Results” tab to the left of the “Search” button on the Search Panel.
This will open a new panel just for refining your imagery search filters. E.g., you can specify a min/max cloud cover threshold, a time of interest, a specific satellite constellation, etc.
Once you are happy with your filters, simply press “<- Back” from the top-left and “Search” from the Imagery Search Panel. This will display a list of images that match your search criteria.
Imagery search results are grouped by date and product type. You can explore your search results even further by selecting the drop down arrows left of each result. This will show each individual image that is included in that set of date and product results.
Additionally by selecting the configure results metadata card above the search results, you can adjust the default metadata fields that are displayed for each individual image so that you can inspect each result in greater detail and display the metadata most important to your curation.
Users that are executing a similar imagery search many times may be interested in saving that search so that it is easier to recreate. Planet ArcGIS Add-In users can now save their search, which will preserve their search filters including their AOI, by selecting the save icon above the search results.
Give your search a name and specify if you’d like to remove the start or end date. Removing the end-date, for example, will make sure that your saved search applies to new imagery as it becomes available.
Save Searches are portable across the Planet Platform. i.e., Saving a search in ArcGIS will allow you to access that same saved search in Planet Explorer, and vice versa.
Stream Preview Imagery
From the search results, Planet ArcGIS Pro Add-In users can stream preview images into their Pro maps by selecting the “Add images to map” icon right of each search result. We refer to these image tiles as “previews” because they are “browse” quality tile layers that are not full-resolution or full-bit depth and don’t contain any multi-spectral information.
Users can also stream multiple results to their ArcGIS Pro map as preview layers by selecting each result and then clicking the “Add all preview layers to the map” icon above the search results.
ArcGIS Add-In users can download Planet imagery directly within ArcGIS Pro. Ordering & downloading imagery will provide access to full bit-depth, multi-spectral geotiff(s) for your selected imagery scenes.
To place an Imagery Order, select the images you’d like to download from the Image Search panel using the check-boxes left of each image. Then select “Order” from the bottom-right of the Imagery Search Panel.
This will pop open an Order Imagery window in ArcGIS Pro. In this window you can further refine your order selection, select your preferred radiometry/rectification, and clip the images if preferred. Selecting “Clip Items to AOI” will clip your selected images to the AOI you used to search. Once your options are set, select “Place Orders”. You must give your order a name to place an order.
Once an order has been placed you can monitor your order and download it (once available for download) from the Planet Order Status Panel. The Order Status Panel will include orders for imagery scenes & Basemap quads. Once an imagery scene is available for download a “Download” button will be available for the Order. If you’ve already downloaded an order before, there will be an option to “Re-Download”. You can also “Open order folder” which will open the file location you originally downloaded the imagery to.
