NASA Landsat Program (NASA Ames Research Center, Earth Science Division, Mail Stop 245-4, Moffett Field, CA 94035-1000 email: CONTACT: Ed Sheffner - Cal. State Univ. Monterey Bay/Ames Research Center ) is the longest running enterprise for acqusition of imagery of the earth from space. The first Landsat satellite was launched in 1972. The next in the series, Landsat 7, is scheduled for launch in May, 1998. The instruments on the Landsat satellites have recorded millions of images, These images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and other applications. Landsat data have been used extensively in agriculture and geology, global change science, education and national security. see Access to Land Satellite Data on the Internet . SEARCH .

Digital Elevation Models: Issues of Data Accuracy and Applications ( Jay Lee, Department of Geography Kent State University Kent, Ohio 44242-0001 Telephone: 330-672-3222 Fax: 330-672-4304 E-mail: . With the increasing availability of data for digital elevation models (DEM) and the software capable of processing them, it is important for users of DEM data to be aware of the effect that data accuracy has on the results of their applications. In this paper, we examined the relationship between simulated errors and the results of extracting hydrological features from DEMs. The simulated errors were controlled to have various degrees of spatial cluterness to allow further investigation of the impact on the extracted hydrological features. The results of our study suggest that even errors of small magnitudes would significantly affect the quality of extracted hydrological features. It is extremely important for users of DEM data to recognize this limitation and not to overly confident on the results of less accurate data.

GIS Techniques for Evaluating Wetland Maps Derived from Remotely Sensed Data* (Joseph Spruce, Risa Wu, Russell Berry) Wetland delineation remains a problematic issue for governmental agencies involved with environmental monitoring. Remotely sensed data, particularly aerial photographs, are important for mapping wetlands at regional scales. New digital remote sensing technologies (e.g., medium- to high-resolution multiband satellite and airborne imagery of visible, near-infrared, mid-infrared, thermal, and radar spectral regions) may improve National Wetlands Inventory (NWI) mapping efforts by increasing map accuracy and reducing map production costs. In response, NASA's Commercial Remote Sensing Program Office performed a study to evaluate the utility of commercially available remote sensing technology for deriving wetland classification and mapping products for the NWI. This paper discusses GIS techniques used to assist this investigation. This project involved processing each remotely sensed data set into wetness maps for comparisons against NWI maps and GPS-based field survey data. GIS tools found in ArcInfo software proved to be indispensable for quantifying and visualizing comparisons of test and reference wetness maps. GISs also assisted in wetness signature evaluation and development by enabling analysts to cross-tabulate unsupervised classifications of remotely sensed data with NWI wetness maps.
