Product Processing and Distribution Service This service enables a user to search for ASTER Data Product(s) and to request delivery of them.
It also enables a user to request for processing of the original data to a higher level that the user desires.
This service is only available for ASTER GDS registered Users.
General Programming Request (GPR) Service GPR is a service that users can submit observation requests, and to obtain high quality observation data at low price.
This service is only available for ASTER GDS registered Users.
Data Acquisition Request Service This service enables a user to acquire ASTER observation data under the user's specific conditions of time, region, and environment. (Non-registered users and General Users are not given the privilege.)
You can request an acquisition by generating a Data Acquisition Request (DAR). GDS will implement the user's DAR to ASTER observation schedule, and will process the data when acquired. However, delivery of the product(s) to the requester is not automated. You need to generate a Data Production Request (DPR) using the Product Processing and Distribution Service, or you can request "DPR Link" at the time of generating your DAR. Please carefully read "Directions for the use of ASTER Data in advance".
