Landsat Data Acquisition Request

You are here

The Landsat Program acquires data according to the Landsat 8 and Landsat 7 Long Term Acquisition Plans (LTAP-8) and (LTAP-7). Please visit the Landsat Acquisition webpage for more information.

Special requests are required to suggest acquisitions of data that do not fall within the candidate images acquired by the logic defined in the LTAPs, and are mainly used to acquire night, low sun elevation, ocean, and ascending day-lit data. They can also be used to increase the probability of acquisition for images within the land mask, particularly for Landsat 7, if the requested image is considered to have significant technical or scientific value.

NOTE: Special requests are not needed for most day-lit (descending) scenes within which any land exists.

Complete and submit the request below. Your request will be considered, reviewed, and elevated for final approval. Please be aware that there is no guarantee that the data will be collected. The probability of data acquisition will depend upon a variety of factors, including the number and priority of other scheduled acquisitions, as well as the cloud cover predictions.


Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
