IKONOS imagery has been used in many commercial, government, and research applications ranging from environment monitoring, to coastal change detection, and to national security. The high costs of IKONOS high end products ͑Pro and Precision products͒ make it extremely attractive to find practical methods that use lower-cost IKONOS Geo products to produce(More)
[1] The Mars Exploration Rover Opportunity investigated four rocks, informally dubbed Barberton, Santa Catarina, Santorini, and Kasos, that are possible stony meteorites. Their chemical and mineralogical composition is similar to the howardite, eucrite, and diogenite group but with additional metal, similar to mesosiderite silicate clasts. Because of their(More)
To evaluate the geometric accuracy of ground points from integrated Global Positioning System (GPS), inertial navigation system (INS), and high-resolution linear array CCD sensor data, this paper presents the mathematical model of the bundle adjustment and the experimental results on the attainable accumcy of ground points versus number and distribution of(More)
Shoreline mapping and shoreline change detection are critical for safe navigation, coastal resource management, coastal environmental protection, and sustainable coastal development and planning. This paper reports the results of IKONOS geopositioning accuracy improvement, showing that a 1-2 meter accuracy can be achieved from 1m-resolution IKONOS Geo(More)
High-precision topographic information from all available data is crucial to many landing site geological and engineering applications. At the same time, precise navigation and localization of the rover as it traverses the Martian surface is important both for its safety and for the achievement of its engineering and scientific objectives. In this paper, we(More)
This paper presents the technology of mapping and rover localization at the two landing sites, Gusev and Meridiani, for the 2003 Mars Exploration Rover (MER) mission. The rover localization and landing site mapping technology is based on the incremental bundle adjustment of an image network formed by Pancam, and Navcam stereo images. The developed(More)
– To date, orbital and ground image data have been mostly separately processed for topographic mapping in Mars landed missions. We are in the process of developing a method for the integration of orbital and ground image networks to enhance precision mapping. In this research, HiRISE stereo images were used as orbital data while ground data include MER-B(More)
This paper presents a system that integrates biologically and geometrically inspired approaches to detecting objects from hyperspectral and/or multispectral (HS/MS), multiscale, multiplatform imagery. First, dimensionality reduction methods are studied and used for hyperspectral dimensionality reduction. Then, a biologically inspired method, S-LEGION(More)
