This has given rise to a need for a multi-purpose interactive aviation weather product generation software solution. This software solution must be platform-independent, multiple data source access configurable, robust, extensible or upgradeable, user-friendly, and an improvement over current visualization applications used in the operational military aviation weather community. This thesis determines whether Unidata MetApps meets these criteria. A software reuse and component-based engineering approach was taken in this thesis. Two experimental applications were constructed using a software design approach resembling the Facade software design pattern. The first application used existing MetApps stand-alone prototype applications, while the second exploited capabilities of the MetApps component library. Both experimental applications were measured against the above set of criteria to determine their suitability for incorporation in platform-independent user-customized aviation weather products generation software. The results prove that a Facade software design approach can be effectively used to build applications. It was determined however that, even though MetApps shows promise, it may not be suitable for incorporation into an operational application.

Visser, BS Captain, USAF Approved: Acknowledgements I would like to express my sincere appreciation to my thesis advisor, Lt Col Timothy Jacobs, for his guidance and support throughout the course of this thesis effort. The insight and experience he provided was greatly appreciated. My gratitude also goes out to Lt Col Walters, for his dry wit, and Major Huffines, for helping me keep things that are truly important in perspective. I would, also, like to thank my organizational sponsor, the Technology Exploitation Branch at the Air Force Weather Agency, for both the technical support and latitude provided to me in this endeavor. I also wish to acknowledge the help from my fellow thesis students from both the Engineering Physics and Electrical and Computer Engineering Departments. Their comments, suggestions, quips, snipes, good-natured haranguing, and occasional much needed “correction-of- attitude” helped keep me from always losing my temper. I am, also, indebted to the late author Theodore S. Geisel. At the age of ten, I was presented by my parents with a copy of Geisel’s “The Sneetches and Other Stories,” and introduced to the English language (some say that this goes a long way to explaining why I write and speak English the way that I do). Finally, and certainly not least, I wish to thank the Lord and my family. Without their patience, understanding, and unconditional love, I would certainly have had a lot tougher time getting through the creation of this thesis than I did. Harmen P.

  • Feature Tracking & Visualization in 'Visit'
    FEATURE TRACKING & VISUALIZATION IN ‘VISIT’ By NAVEEN ATMAKURI A thesis submitted to the Graduate School—New Brunswick Rutgers, The State University of New Jersey in partial fulfillment of the requirements for the degree of Master of Science Graduate Program in Electrical and Computer Engineering written under the direction of Professor Deborah Silver and approved by New Brunswick, New Jersey October 2010 ABSTRACT OF THE THESIS Feature Tracking & Visualization in VisIt by Naveen Atmakuri Thesis Director: Professor Deborah Silver The study and analysis of large experimental or simulation datasets in the field of science and engineering pose a great challenge to the scientists. These complex simulations generate data varying over a period of time. Scientists need to glean large quantities of time-varying data to understand the underlying physical phenomenon. This is where visualization tools can assist scientists in their quest for analysis and understanding of scientific data. Feature Tracking, developed at Visualization & Graphics Lab (Vizlab), Rutgers University, is one such visualization tool. Feature Tracking is an automated process to isolate and analyze certain regions or objects of interest, called ‘features’ and to highlight their underlying physical processes in time-varying 3D datasets. In this thesis, we present a methodology and documentation on how to port ‘Feature Tracking’ into VisIt. VisIt is a freely available open-source visualization software package that has a rich feature set for visualizing and analyzing data. VisIt can successfully handle massive data quantities in the range of tera-scale. The technology covered by this thesis is an improvement over the previous work that focused on Feature Tracking in VisIt.

  • Hibbard, W. Confessions of a Visualization Skeptic
    Confessions of a Visualization Skeptic 15.04.2003 11:07 Uhr Hibbard, W. Confessions of a Visualization Skeptic. Computer Graphics 34(3), 11-13. 2000. Confessions of a Visualization Skeptic Bill Hibbard Space Science and Engineering Center University of Wisconsin - Madison May 2000 There is no doubt that visualization is very useful, by enabling people to understand that masses of data and information otherwise hidden inside of computers. However, after many years developing visualization systems I have to confess to skepticism about many of the hottest (i.e., coolest) visualization ideas. Virtual Reality When I started at the Space Science and Engineering Center (SSEC) in 1978 they were already experimenting with red-green stereo viewing of pairs of images from satellites over the eastern and western United States. This gave viewers a qualitative feel for the altitudes of clouds. While these displays were very interesting, they never became the basis for serious work because scientists were not prepared to make quantitative judgements based on their depth perception. Instead, they developed algorithms for estimating the altitudes of cloud tops from these image pairs. Their primary serious use of visualization was to pick likely candidates for their automated cloud-tracking algorithms, and to check the quality of the resulting wind estimates. Those tasks required animated 2 D images, but not 3 D. Nevertheless, the search was on at SSEC for useful 3 D visualizations. We attended the annual Siggraph conferences, studied Foley and van Dam’s book, experimented with a variety of rendering techniques that ran overnight on IBM mainframes, and experimented with cross-polarized stereo displays of our 3 D rendered images.

Lindesay ~ ;'Centre for Resource and Environmental Studies, Australian National University, Canberra, Australia hANU Supercomputer Facility, Australian National University, Canberra, Australia ~Department of Geography, Australian National University, Canberra, Australia Abstract Computer visualization and data analysis tools are an essential component in the study and evaluation of climate model output. A number of useful visualization and analysis tools already exist, each with its own set of unique strengths. A translation tool is needed to convert data from the large number of model output Ikwmats into formats suitable for use with visualization and analysis tools. Such a translator would allow a researcher using a climate model to easily exploit a large number of visualization and analysis tools. Our goal is to develop a translation tool lk~r UNIX computer systems that will be highly portable, very simple to use, and easily expandable. The translation program, The ANU translator will feature a graphical user interface when run on any system with an XII interface. It will work with a number of climate model formats, including: CCMI, CCM2, RegCM2, MM5, CSIRO, and ANU-CTM. It will produce output in a range of data file lormats, including Vis5D, GRADS, and neICDF.

  • Visualizing High-Resolution Climate Data
    Visualizing High-Resolution Climate Data Sheri A. Voelz1 and John Taylor1, 2 1Mathematics & Computer Science, Argonne National Laboratory, Argonne, Illinois 60439 2Environmental Research Division, Argonne National Laboratory, Argonne, Illinois 60439 {voelz, jtaylor}@mcs.anl.gov http://www-climate.mcs.anl.gov/ Abstract. The complexity of the physics of the atmosphere makes it hard to evaluate the temporal evolution of weather patterns. We are also limited by the available computing power, disk, and memory space. As the technology in hardware and software advances, new tools are being developed to simulate weather conditions to make predictions more accurate. We also need to be able to visualize the data we obtain from climate model runs, to better understand the relationship between the variables driving the evolution of weather systems. Two tools that have been developed to visualize climate data are Vis5D and Cave5D. This paper discusses the process of taking data in the MM5 format, converting it to a format recognized by Vis5D and Cave5D, and then visualizing the data. It also discusses some of the changes we have made in these programs, including making Cave5D more interactive and rewriting Cave5D and Vis5D to use larger data files. Finally, we discuss future research concerning the use of these programs. 1 Introduction Weather simulations are important in helping us understand the key components that determine our weather, particularly extreme events. Manipulating the variables within the simulations gives additional insight into how a particular weather pattern is produced. Unfortunately, many variables are involved in these simulations, making the output files large. For example, one day’s data in v5d file format can be around one gigabyte.

  • 64 Vis5d Version 5.2 1. OVERVIEW of Vis5d Vis5d Is a Software
    64 Vis5D Version 5.2 1. OVERVIEW OF Vis5D Vis5D is a software system that can be used to visualize both gridded data and irregularly located data. Sources for this data can come from numerical weather models, surface observations and other similar sources. Vis5D can work on data in the form of a five-dimensional rectangle. That is, the data are real numbers at each point of a "grid" which spans three space dimensions, one time dimension and a dimension for enumerating multiple physical variables. Of course, Vis5D works perfectly well on data sets with only one variable, one time step (i.e. no time dynamics) or one vertical level. However, your data grids should have at least two rows and columns. Vis5D can also work with irregularly spaced data which are stored as "records". Each record contains a geographic location, a time, and a set of variables which can contain either character or numerical data. A major feature of Vis5D is support for comparing multiple data sets. This extra data can be incorporated at run-time as a list of *.v5d files or imported at anytime after Vis5D is running. Data can be overlaid in the same 3-D display and/or viewed side-by-side spread sheet style. Data sets that are overlaid are aligned in space and time. In the spread sheet style, multiple displays can be linked. Once linked, the time steps from all data sets are merged and the controls of the linked displays are synchronized. The Vis5D system includes the vis5d visualization program, several programs for managing and analyzing five-dimensional data grids, and instructions and sample source code for converting your data into its file format.
