For remote sensing missions, the fractionated functionality of CubeSats provides a potential way to reduce cost and risks while maintaining comparable operational capabilities. This paper describes two CubeSat remote sensing missions developed by The Aerospace Corporation. The CubeSat Multispectral Observation System (CUMULOS) and R3 sensors will be hosted on 3U CubeSats developed by Aerospace....

the growing population and increasing socio-economic necessitiescreates a pressure on land use/land cover. nowadays, land use change detection using remote sensing data provides quantitative and timely information for management and evaluation of natural resources. this study investigates the land use changes in part of hableh rood watershed of iran using landsat 7 and 8 (sensor etm+ and oli) i...

Earth observation data obtained from remote sensors must undergo radiometric calibration before use in quantitative applications. However, the large view angles of the panchromatic multispectral sensor (PMS) aboard the GF-4 satellite pose challenges for cross-calibration due to the effects of atmospheric radiation transfer and the bidirectional reflectance distribution function (BRDF). To addre...

The Landsat 8 spacecraft was launched on 11 February 2013 carrying the Operational Land Imager (OLI) payload for moderate resolution imaging in the visible, near infrared (NIR), and short-wave infrared (SWIR) spectral bands. During the 90-day commissioning period following launch, several on-orbit geometric calibration activities were performed to refine the prelaunch calibration parameters. Th...

Road feature extraction from the remote sensing images is an arduous task and has a significant role in various applications of urban planning, updating maps, traffic management, etc. In this paper, new band combination (B652) to form road index (RI) OLI multispectral bands based on spectral reflectance asphalt, presented for extraction. The B652 converted by normalization. morphological operat...

The Operational Land Imager (OLI) on Landsat-8 represents a generational change from heritage Landsat instruments in its design, while it maintains data continuity with the 40+ year Landsat data archive. It preserves the 30-m ground sample distance, 185-km swath width and VIS/NIR/SWIR spectral bands. Furthermore, data continuity resulted from extensive pre-launch and on-orbit calibration and ch...

The Operational Land Imager (OLI) is a new Landsat sensor being developed by the joint USGS-NASA Landsat Data Continuity Mission (LDCM) that exhibits the potential to be a state-of-the-art instrument for studying inland and coastal waters. With upgrades such as a new Coastal Aerosol band, 12 bit quantization, and improved signal-to-noise, OLI will be spectrally and radiometrically superior to i...

Landsat 8, the most recently launched satellite of the series, promises to maintain the continuity of Landsat 7. However, in addition to subtle differences in sensor characteristics and vegetation index (VI) generation algorithms, VIs respond differently to the seasonality of the various types of vegetation cover. The purpose of this study was to elucidate the effects of these variations on VIs...
