America’s 95,000 miles of coastline are subject to natural and man-made processes that continually alter its shape and character. The accuracy, consistency, and currency of our national shoreline need to be frequently ensured, especially during this era of rapid coastal development. Countless applications depend on NOAA’s National Spatial Reference System to determine where the land meets the s...

This paper evaluates accuracies of selected image classification strategies, as applied to Landsat imagery to assess urban impervious surfaces by comparing them to reference data manually delineated from high-resolution aerial photos. Our goal is to identify the most effective methods for delineating urban impervious surfaces using Landsat imagery, thereby guiding applications for selecting cos...

The direct geo-referencing of sensors based on a combination of relative kinematic GPS-positioning and inertial measurement units (IMU) has reached a high accuracy level and growing application. It includes the advantage of a very flexible use, independent upon control points which are only required for the system calibration and independent upon block or strip configurations. It is in use in a...

Although technology has advanced at breathless pace, wildfire still bursts out every year all over the world. There are various wildfire monitoring system employed in diferrent countries, most of them are depended on photos or videos to identify features of wildfire, after wildfire happened. Delay of confirmation is diverse based on used techonologies. An autonomous forest patrol system by Unma...

This paper describes an approach to classification of noisy signals using a technique based on the fuzzy ARTMAP neural network (FAMNN). The proposed method is a modification of the testing phase of the fuzzy ARTMAP that exhibits superior generalization performance compared to the generalization performance of the standard fuzzy ARTMAP in the presence of noise. An application to textured gray-sc...

soil organic matters are considered as the animal and plant residues and active components of soils. the cultivation practices will cause the quick removal of organic matters in soils even in those which are not affected by erosion. this study was carried out to assess the level of soil humus in the pilot area, to investigate the positive or negative effect of humus level on soil and to introdu...
