Top geospatial companies post-sales service/support from Geospatial World Readers' Survey 2013
The Survey reflects how top geospatial companies are perceived by key stakeholders across a broad spectrum of criteria. Respondents reflect a wide range of spectrum – staffers across a variety of geospatial players, academia, user industries to plain geoenthusiasts.

60 terabytes of Landsat 8 images, with a powerful cloud coverage filter (thanks to Band 9), updated every day and available to ArcGIS Online users

For the Landsat 8 services, Esri daily downloads the latest, approximately 300 Landsat 8 scenes and adds them to a set of image services that contain the best and most recent 50,000 Landsat 8 scenes, which require about 60 terabytes for storage. These scenes are hosted on Esri's cloud infrastructure and available for access in different modes.

By default, the user views the best scenes. The best scene is determined using a weighting of cloud coverage and age of the scenes. Users can reorder the scenes based on metadata attributes, lock onto a specific scene, or use a time slider to see how an area changes with time.

Not all scenes are kept; otherwise, the data volumes for storage would continually increase. Instead, older scenes are removed. Typically, the latest four scenes with less than 50 percent cloud coverage are kept, as well as the scene that is nearly cloud free .

Band 9, it’s one of the most interesting features of Landsat 8. It covers a very thin slice of wavelengths: only 1370 ± 10 nanometers. Few space-based instruments collect this part of the spectrum, because the atmosphere absorbs almost all of it. Landsat 8 turns this into an advantage. Precisely because the ground is barely visible in this band, anything that appears clearly in it must be reflecting very brightly and/or be above most of the atmosphere. 

Band 9 is just for clouds! It’s designed especially for cirrus clouds – high, wispy “horsetails”. Cirrus are a real headache for satellite imaging because their soft edges make them hard to spot, and an image taken through them can contain measurements that are off by a few percent without any obvious explanation. Band 9 makes them easy to account for.
