Abstract

A pilot study is very briefly summarized in the article. The study tested the potential of multi-spectral digital imagery for discrimination of seagrass densities and species, algae, and bottom types. Imagery was obtained with the Compact Airborne Spectral Imager (casi) and two flight lines flown with hyper-spectral mode. The photogrammetric method used allowed interpretation of the highest quality product, eliminating limitations caused by outdated or poor quality base maps and the errors associated with transfer of polygons. Initial image analysis indicates that the multi-spectral imagery has several advantages, including sophisticated spectral signature recognition and classification, ease of geo-referencing, and rapid mosaicking.

Mission planning for operational data acquisition campaigns with the {sup casi}

Conference Wulder, M; Mah, S; Trudeau, D

The compact airborne spectrographic imager (casi) is a pushbroom style airborne remote sensing instrument which has been used for a variety of applications suited to its high performance, portability, flexibility in choice of spectral bands and imaging combinations, image geocoding capabilities, low-cost data acquisition, and relative ease of use and processing. As the casi may be configured to operate in either spatial or spectral mode the user decides which is most appropriate for the needs of a particular study. Spatial mode is appropriate for identifying and mapping attributes spatially using a priori spectral knowledge whereas spectral mode is well suitedmore »« less
Using digital scanned aerial photography for wetlands delineation. Scientific paper, 2-5 Apr 92

Technical Report Anderson, J; Roos, M

The Corps of Engineers. U.S. Fish and Wildlife Service and the Environmental Protection Agency are charged the responsibility to jointly manage the nation's wetlands in accordance with the Clean Water Act and the Rivers and Harbors Act. The Corps' role is enforcement of regulations concerning dredging and filling of specific types and areas of wetlands that fall within jurisdictional boundaries. Current research is being conducted to enhance the field scientist's ability to manage these ecosystems using digital aerial photography, image processing and photo interpretation logic. This paper presents techniques used to scan (digitize), archive and use digital aerial photography formore »« less
Automated ortho-rectification of UAV-based hyperspectral data over an agricultural field using frame RGB imagery

Journal Article Habib, Ayman; Han, Youkyung; Xiong, Weifeng; ... - Remote Sensing

Low-cost Unmanned Airborne Vehicles (UAVs) equipped with consumer-grade imaging systems have emerged as a potential remote sensing platform that could satisfy the needs of a wide range of civilian applications. Among these applications, UAV-based agricultural mapping and monitoring have attracted significant attention from both the research and professional communities. The interest in UAV-based remote sensing for agricultural management is motivated by the need to maximize crop yield. Remote sensing-based crop yield prediction and estimation are primarily based on imaging systems with different spectral coverage and resolution (e.g., RGB and hyperspectral imaging systems). Due to the data volume, RGB imaging ismore »« less

Using high spatial resolution satellite imagery to map forest burn severity across spatial scales in a Pine Barrens ecosystem

Journal Article Meng, Ran; Wu, Jin; Schwager, Kathy; ... - Remote Sensing of Environment

As a primary disturbance agent, fire significantly influences local processes and services of forest ecosystems. Although a variety of remote sensing based approaches have been developed and applied to Landsat mission imagery to infer burn severity at 30 m spatial resolution, forest burn severity have still been seldom assessed at fine spatial scales (≤ 5 m) from very-high-resolution (VHR) data. Here we assessed a 432 ha forest fire that occurred in April 2012 on Long Island, New York, within the Pine Barrens region, a unique but imperiled fire-dependent ecosystem in the northeastern United States. The mapping of forest burn severitymore »« less

Estuarine and Tidal Freshwater Habitat Cover Types Along the Lower Columbia River Estuary Determined from Landsat 7 Enhanced Thematic Mapper (ETM+) Imagery, Technical Report 2003.

Technical Report Garono, Ralph; Robinson, Rob

Developing an understanding of the distribution and changes in estuarine and tidal floodplain ecosystems is critical to the management of biological resources in the lower Columbia River. Columbia River plants, fish, and wildlife require specific physicochemical and ecological conditions to sustain their populations. As habitats are degraded or lost, this capability is altered, often irretrievably; those species that cannot adapt are lost from the ecosystem. The Lower Columbia River Estuary Partnership (Estuary Partnership) completed a comprehensive ecosystem protection and enhancement plan for the lower Columbia River and estuary in 1999 (Jerrick, 1999). The plan identified habitat loss and modification asmore »« less
