The Mississippi Institutions of Higher Learning and NASA's Commercial Remote Sensing program address issues relating to the commercialization of remote sensing technologies. This technology, destined to dominate the next millenium, finds wide applicability in areas such as those related to telemedicine, intelligent transportation systems, fanning, and forestry. Presentations and panel topics will include: (1) the science of remote sensing, (2) sociological implications, and (3) issues relating to geographical information systems.

Many research areas, particularly in environmental sciences, require techniques of both Geographic Information Systems (GIS) and scientific visualization systems. However, integrating these two technologies in a way that is seamless for the user presents many challenges. This research effort focuses on assessing current solutions to these challenges and proposing new alternatives.

Emergency planning officials at the county and municipal level need accurate information describing the landcover, slope and elevation of their areas of jurisidiction. This information is needed to assess areas of potential flood risk from hurricane storm surge and rainfall, and to develop mitigation plans to reduce risk. These needs include monitoring residential and commercial development in potential flood hazard areas and development that alters the amount of impervious surface area within and surrounding the city. In this project high-resolution multispectral imagery was merged with high-resolution topographic survey data to form a risk assessment and hazard mitigation tool for the city of Long Beach, Mississippi. Long Beach is a small city on the Mississippi Gulf Coast that has undergone rapid residential and commercial growth due to casino development and increased tourism. The multispectral imagery was obtained from Positive Systems Incorporated. The imagery contains four bands, three visible and one infrared, with resolution of one meter. The imagery was geo-referenced using digital transportation data at 1:24,000 scale and image to image registration to create a mosaic image of the city of Long Beach. This mosaic was classified to determine the amount of property within the city covered by impervious surface. In addition to the imagery, high-resolution topographic data were gathered using a Light Detection And Ranging (LIDAR) system. This data set contains an elevation point for each square meter of Long Beach and has an elevation accurracy of [+ or -] 0.5 feet. These data were used to develop a Digital Elevation Model that was used to compute the slope of each pixel in the imagery and to delineate basins within the city. The combination of the imagery and topographic data will be used to parameterize an overland flow model that will be used to determine flood risks throughout the city. The imagery is also being used to evaluate the suitability of hurricane shelters. In particular the imagery is used t o assess the hazards associated with nearby trees and other potential falling objects. The model implementation is expected to be completed by July, 2000 and will be used as a pilot study to test the feasibility of these types of studies for the entire Mississippi Gulf Coast.

The importance of considering how data will be analyzed early in the planning of an investigation or experiment cannot be overemphasized. The distinguished statistician Sir R.A. Fisher said, "To call in the statistician once the experiment is done may be no more than asking him to perform a postmortem examination: he may be able to say what the experiment died of." Don't let this happen to you! Come to the Annual meeting of the Mississippi Academy of Sciences and MEET THE STATISTICAN. The members of the Division of Mathematics, Computer Science, and Statistics will be providing free, 20 minute consultations in the areas of experimental design, statistical design & analysis selection, and sample size determination. Some analyses may be possible with advanced arrangements. Contact the division chairman, Walt Brehm, 81st Medical Group, 301 Fisher St., Rm 1A132, Keesler AFB, MS 39534 or to arrange an appointment. Students are welcome and walk-ins may be accepted. It could be the most important 20 minutes of you whole project.
