Landsat MSS, TM, ETM Archive:CAST, in association with ArkansasView, maintains an extensive archive of historic Landsat imagery. Raw scenes from Landsat 1-3 (MSS), Landsat 4-5 (TM) and Landsat 7 (ETM) are available from the archive. Dates range from 1972 - Present.  All popular remote sensing/imageprocessing software can import these files. Click here to view the archive.

CAST's TerraHawk Airborned System: The TerraHawkTM system is a low-cost, turnkey sensor package for airborne imaging. It is a fully integrated imaging system featuring GPS navigation, automated camera/computer function and data management for ease of use. It features autonomous roll, pitch, and yaw camera control at NADIR view and alignment with GPS heading. While the system is suitable for a wide variety of imaging applications, it was specifically designed for the practical implementation and repetitive remote sensing for micromanagement of agricultural crops and other natural resources. The system purchased by CAST is equipped with the DuncanTech MS4100 sensor, a three band CCD sensor: (NIR, visible red, visible green). On May 31, 2006 CAST personnel tested the system.

Land-use & Land-cover (LULC) Mapping: Accurate Land-use Maps can help scientists identify potential problem areas, predict where problems are likely to occur in the future, and to model solutions to critical natural resource issues. The Arkansas LULC Program is dedicated to providing up-to-date Land-use and Land-cover maps for Arkansas.

The two maps below show crop differences between 2004 (left) and 2006 (right) in the Walnut Ridge area. The dark yellow represents the corn crop. A definite increase in corn acreage can be seen in 2006.

 

Ikonos from GeoEye: This satellite image of cropland near Jonesboro, Arkansas, was acquired by a multispectral sensor onboard the Ikonos spacecraft. The sensor onboard Ikonos is able to resolve objects on the ground as small as one square meter. In this image the amber fields are harvested rice fields, the blue-green fields are soybean fields, the brown fields are bare soil. High resolution satellite imagery offers great potential for applications such as precision farming, utility planning, forestry, real estate, disaster relief, etc.

QuickBird from Digital Globe: This satellite image of Fayetteville, Arkansas was acquired by a multispectral sensor onboard the QuickBird spacecraft. The QuickBird sensor is able to resolve objects on the ground smaller than one square meter. This real-color image depicts a mixed urban environment. High resolution satellite imagery offers great potential for applications such as urban planning, precision farming, utility mapping, forestry, real estate, disaster relief, etc.

RAPID Landsat Data Acquisition: This Landsat 7 image of Lake Jack Lee in the Felsenthal National Wildlife Refuge (Ashley and Bradley counties in Arkansas) was the first image acquired and processed by the RAPID project. This image was available to the public on the internet, at no cost, 12 minutes after it's receipt from the U.S. Geological Survey's EROS Data Center.

These pseudo real-color Landsat 7 images, showing flooding along the Black River in northeast Arkansas in March 2002, were acquired and processed using the RAPID program. The first image shows what the area looks like in the dry season. The second image shows the area inundated by the river, and flooded land adjacent to the river. The second image clearly depicts flood damage to Arkansas' important winter wheat crop This RAPID image was available within a few hours of it's acquisition.
