Use of the ER2 and IFSAR for digital terrain matrix, difference digital terrain matrix, and vector difference digital terrain matrix collection
Abstract
A national digital terrain matrix (DTM) archive with submeter elevation precision and three meter or less post spacing will have numerous commercial government and research uses. The Lockheed Martin Missiles and Space Digital Terrain Elevation Mapping System (DTEMS) will be used to collect a DTM archive with average relative one {sigma} elevation precision of 0.3 meter, average absolute one U elevation precision less than 0.6 meter, and one to three meter post spacing (posting). DTEMS data will satisfy National Map Accuracy Standards (NMAS) contour intervals of one to two meters. DTEMS will also archive orthrectified digital polarimetric synthetic aperture radar (SAR) imagery with one to three meter resolution. A difference digital terrain matrix (DDTM) is defined as a digital data file containing elevation changes in a DTM. A DDTM archive will be useful for detection and measurement of natural or man made changes in terrain elevation. Using DTEMS to make periodic repeat DTM collections and coherent elevation change detection (CECD) to sense small elevation changes, DTEMS will be capable of resolving elevation changes of a few centimeters. A vector difference digital terrain matrix (VDDTM) is defined as a digital data file containing the X, Y and Z displacements of themore »

Efficient solution of global climate models requires effectively handling disparate length and time scales. Implicit solution approaches allow time integration of the physical system with a time step dictated by accuracy of the processes of interest rather than by stability governed by the fastest of the time scales present. Implicit approaches, however, require the solution of nonlinear systems within each time step. Usually, a Newton s method is applied for these systems. Each iteration of the Newton s method, in turn, requires the solution of a linear model of the nonlinear system. This model employs the Jacobian of the problemdefiningmore »

IFSAR for the Rapid Terrain Visualization Demonstration
The Rapid Terrain Visualization Advanced Concept Technology Demonstration (RTVACTD) is designed to demonstrate the technologies and infrastructure to meet the Army requirement for rapid generation of digital topographic data to support emerging crisis or contingencies. The primary sensor for this mission is an interferometric synthetic aperture radar (IFSAR) designed at Sandia National Laboratories. This paper will outline the design of the system and its performance, and show some recent flight test results. The RTV IFSAR will meet DTED level III and IV specifications by using a multiplebaseline design and highaccuracy differential and carrierphase GPS navigation. It includes innovative nearrealtime DEMmore » 
On the use of finite difference matrixvector products in NewtonKrylov solvers for implicit climate dynamics with spectral elements
Efficient solutions of global climate models require effectively handling disparate length and time scales. Implicit solution approaches allow time integration of the physical system with a step size governed by accuracy of the processes of interest rather than by stability of the fastest time scales present. Implicit approaches, however, require the solution of nonlinear systems within each time step. Usually, a Newton's method is applied to solve these systems. Each iteration of the Newton's method, in turn, requires the solution of a linear model of the nonlinear system.

Evaluation of the use of flat terrain models versus complex terrain screening models in estimating pollutant transport and deposition in complex terrain
A study was performed to determine the validity of using the flat terrain, Gaussian plume Industrial Source Complex Short Term and Industrial Source Complex Long Term models for modeling sources in complex terrain and to ascertain whether deposition rates estimated could be improved upon through the use of advanced, particle size dependent deposition models. 15 refs., 11 tabs.
