ACRES ASTER price list

Sources of ASTER data

ACRES can draw upon the following sources of ASTER data to satisfy customer needs.

1. ERSDAC archive

The Earth Remote Sensing Data Analysis Centre (ERSDAC) in Japan holds a comprehensive archive of all ASTER acquisitions. It holds processed products of over 700,000 Level 1A scenes and over 180,000 Level 1B scenes. ACRES can search this archive and organise the purchase of these products on behalf of clients. In addition, ACRES can organise for ERSDAC to process ASTER data into higher level products (see "Processing Levels" below).

2. ACRES archive

There are two types of ASTER data in the ACRES archive:

ACRES USGS ASTER data: This data was originally sourced from the EROS Data Centre, USGS. It consists of over 14,000 level 1A scenes and over 5000 level 1B scenes with acquisition dates ranging mostly from March 2000 to June 2002. The cloud free scenes from this part of the ACRES archive cover approximately 60-70% of Australia's land mass.
ACRES ERSDAC ASTER data: This is ERSDAC data that has already been imported for a client order and subsequently placed in the ACRES archive. It also consists of Level 1A and Level 1B data.

All ASTER scenes in the ACRES archive can be searched using the ACRES Digital Catalogue. Please note, there are different pricing and licensing conditions between ACRES USGS ASTER data and ACRES ERSDAC ASTER data.

General Programming Request (GPR)

ACRES can organize with ERSDAC to acquire imagery over your area of interest. There are important conditions (see below) associated with this request to which customers must fully understand and agree in writing. There is no charge to place the request, but if the acquisition is successful, customers are obliged to purchase the various processing levels for that scene, as described above.

For example, a successful day-time future acquisition will result in a customer receiving three products (levels 1A, 1B and ortho) for that scene, for a total cost of $580.

Conditions associated with General Programming Requests. (You need to fully understand and agree to these conditions).
To request a future acquisition, the General Programming Request Order Form (see below) needs to be completed and signed by customers.

Processing levels and product details

Customers who wish to derive their own Digital Elevation Model (DEM) will generally purchase Level 1A data which is path oriented and has no radiometric or geometric corrections applied. Customers wanting these corrections applied would normally purchase Level 1B data which is also path oriented.

Ortho-corrected products from ERSDAC are "relative" ortho products. So, even though the ASTER derived DEM has been used for ortho-correction, the control points are based on the satellite model and post-pass ephemeris information. Hence, there may still be a block shift in absolute locational accuracy of around 50 metres (and up to about 200 metres worst case) in the final product.

All processing levels, including other higher level products are described in more detail on the ERSDAC web page.
Additional details about ERSDAC ASTER products are available in the ERSDAC Release Notes. [ERSDAC]

Data format

ASTER data from ACRES is archived and supplied in HDF format, which can be read by a number of image processing systems. Some useful links about HDF format include:

Licensing

Both ACRES ERSDAC ASTER Data and ACRES USGS ASTER Data are sold under license, but with differing conditions. Special copyright conditions apply to the sale of satellite data. In order to purchase satellite data products, users must agree to the relevant licence conditions covering its use. See ACRES End-User ASTER Licence Agreement.
