| Airborne aerosols contaminate satellite imagery, making it difficult for analysts to characterize surface targets. The amount of contamination is due to aerosol loading, best quantified by aerosol optical depth (AOD). Level 2 AERONET data provides ground truth AOD measurements. Unfortunately, targets are not likely to be near an AERONET station. This thesis examines two methods of quantifying AOD in lieu of AERONET data: Moderate Resolution Imaging Spectroradiometer (MODIS) AOD retrievals ... |

| The Worldview-2 satellite, scheduled for launch in 2009, will have a multispectral sensor with several additional spectral bands not available on current multispectral sensors. This research investigates the use of the additional yellow spectral band to derive bathymetry. A hyperspectral image acquired from the AVIRIS sensor was used as a substitute image for the Worldview-2 multispectral sensor. The image was processed using the Stumpf et al. (2003) ratio method to ... |

| A technique known as the Shadow Method was developed for calculating aerosol optical depths by measuring the radiance difference between shaded and unshaded regions in high-resolution satellite imagery by Vincent (2006). Previous research investigated use of the Shadow Method in regions of dust obscuration using buildings and clouds as shadow generation sources and a variety of background surfaces. A recurring low bias was seen when using the Shadow Method with ... |

|
| The ability to produce high-resolution images of the Earth's surface from space has flourished in recent years with the continuous development and improvement of satellite-based imaging sensors. Earth-imaging satellites often rely on complex onboard navigation systems, with dependence on Global Positioning System (GPS) tracking and/or continuous post-capture georegistration, to accurately geolocate ground targets of interest to either commercial and military customers. Consequently, these satellite systems are often massive, expensive, and ... |

| Effectiveness in modern warfare demands rapid, lethal, and stealthy response to a wide variety of adversaries. This requires, in part, the ability to conduct air transport operations to locations where there are no existing runways, and where engineers cannot be prepositioned. One of the most difficult problems is locating large, smooth, flat, and obstruction-free areas that are also sufficiently firm to support at least one aircraft operation, and preferably, many. ... |

| Remote sensing of ocean color provides synoptic surface ocean bio-optical properties but is limited to real-time or climatological applications. Many applications, including navy mission planning using electro-optical sensor performance models, would benefit from a forecast capability. To achieve this, we couple satellite imagery with numerical circulation models to provide short-term (24-48 hr) forecasts of bio-optical properties. These are first-order approaches; they do not account for any biogeochemical mechanistic processes (growth, ... |

| Fog has always been a difficult phenomenon to forecast. Its unpredictable nature and propensity to quickly decrease visibilities have had adverse effects on military operations for many years across the Korean peninsula. It is particularly difficult to prepare forecasts or plan operations for remote locations with limited fog detection ability. For detection at night, over large areas, and in remote locations, satellite observations are the best solution. This thesis used ... |

|
| The advancement and proliferation of high-resolution commercial imaging satellites presents a new opportunity for overland aerosol characterization. Current aerosol optical depth retrieval methods typically fail over areas with high surface reflectance, such as urban areas and deserts, since the upwelling radiance due to scattering by aerosols is small compared to the radiance resulting from surface reflection. The method proposed here uses shadows cast on the surface to exploit the differences ... |

| To traditional moderate or low resolution satellite data, the data processing or information detecting is only on a per-pixel basis because of the impacts to geometric accuracy of spatial resolution. Thereby only the spectral information is used for the classification. High spatial resolution sensors involves a general increase of spatial information and the accuracy of results may decrease on a per-pixel basis. In order to realize the full potential of ... |

| Commercially available satellite imagery represents a growing threat to U.S. military operations. To mitigate this threat, the operational commander has a variety of techniques or methods to consider during planning. Some mitigation methods, such as shutter control, diplomacy, or buy-to-deny, require approval and coordination with outside agencies. Other methods, such as jamming, laser blinding, or synchronized operations, require a thoroughly integrated plan to ensure U.S. forces are protected and able ... |

Encompassing approximately 445,170 hectares (1.1 million acres), it is the single largest TRADOC installation. Because Fort Bliss is located within an arid ecosystem characterized by slow vegetative growth, its land is more susceptible to long-term disturbance. Fort Bliss natural resource managers require a timely and cost-effective ... |

| A new operating mode for imaging satellites has been developed. The non-imaging mode is designed to provide high temporal resolution data time varying targets. The idea is to use linear pushbroom arrays with kilohertz sampling rates to not only detect, but also measure the frequency of temporally varying targets. For satellite operations this will involve satellite slewing at a rate which cancels the effects of satellite orbital motion. This concept ... |

| The U.S. Air Force is in the process of implementing GeoBase, a geographic information system (GIS), throughout its worldwide installations, Air Force GIS needs can be augmented by imagery from aerial and satellite platforms. Imagery has greatly improved over the past several years and provides high resolution coverage of features on earth. Various imagery types will significantly increase GeoBase usefulness in a range of mission requirements, Potential Air Force uses ... |

|
| The performance requirements for the Advanced Land Imager were developed under NASA's New Millennium Program and were intended to facilitate the validation of new sensor technologies and architectures for potential application in future remote sensing missions. The Advanced Land Imager (ALI) was designed and flown well before the Landsat Data Continuity Mission (LDCM) specifications were developed. Nevertheless, the science focus of the ALI technology validation was Landsat data continuity. Therefore, ... |
