“…In this field, two-dimensional representations have been completely superseded since three-dimensional (3D) visualization is closer to reality as well as easier to interpret. Furthermore, it allows the user to interact realistically with the environment [20,27].…”

This paper is focused on the analysis of virtual representation of terrain through the web, and shows the steps to follow in order to put into practice a virtual interactive terrain visualization system. The recent developments of threedimensional visualization systems can be naturally applied to terrain visualization targeted to the web, driving to a higher interaction level. Traditionally it has been implemented with 2D systems due to the huge data volume involved, but nowadays several possible technologies allow to achieve a 3D representation; two of them are analyzed in depth: VRML as an exponent of Web3D technology, and open source threedimensional graphic libraries. Their fundamental characteristics are considered, and their methodologies, pros and cons are illustrated by means of the development of some practical applications for terrain visualization, taking special attention in the implementation of the interaction facilities.

“…However, overall time-series effects (i.e., extended drought, infestation history) and relative spatial effects (i.e., arrangement of landscape patches, landforms, slopes, and soil characteristics) are seldom considered in beetle-infected forests [2,10,23]. 3-D landscape visualization allows the overlaying and integration of the combined effects of diverse interactive geo-information into simplified and integrated 3-D media [24] (Figure 4). …”

After a century of fire exclusion, western US forests are vulnerable to wildfire and bark beetles. Although integrated fire and pest management programs (e.g., prescribed burning and thinning) are being implemented efficiently, damage to forests continues.Management challenges come in the forms of diverse land ownership, dynamic forest landscapes, the uncertainty effect of management strategies, and social interaction of the increasing wildland-urban interface. Three-dimensional (3-D) landscape visualization is comprised of multi-spatial, multi-temporal, and multi-expression elements. Supplemented with GIS database, remote sensing images, and simulation models, this technique can provide a comprehensive communication medium for decision makers, scientists, stakeholders, and the public with diverse backgrounds on the wildfire and forest bark beetle management. The technique we describe here can be used to organize complicated temporal and spatial information, evaluate alternative management operations, and OPEN ACCESSForests 2010, 1 83 improve decision-making processes. The application and limitations of our technique are also discussed.

“…This in-turn requires the use of multiple elevation surfaces which has already been discounted in the "overhang" paragraph above. (Baer & Campbell, 2003;Hirtz, Hoffmann, & Nüesch, 1999;Wasilewski, Faust, Grimes, & Ribarsky, 2002) Our intent is not to replicate geospecific object placement within a particular locale using hard-to-find high resolution data (e.g. LIDAR elevation data and sub-meter imagery), but to use readily available medium-resolution elevation and imagery data that can be used to create large-scale geotypical terrains.…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instruction, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, ABSTRACTVirtual battlefields devoid of vegetation deprive soldiers of valuable training in the critical aspects of terrain tactics and terrain-based situational awareness, but creating realistic landscapes by hand is notoriously expensive; requiring both proprietary tools and trained artists, hampering rapid scenario generation and limiting reuse.GENETICS is a new object placement scheme where the arduous task of placing vegetation objects is reduced to finding readily-available source data and setting a few parameters. Our approach constructs large-scale natural environments at run-time using a procedural image-based algorithm without the need for skilled artists or proprietary tools. The resulting vegetation-laden terrain looks realistic, and the algorithm can be extended to incorporate a wide variety of environmental factors. GENETICS offers researchers the ability to quickly and easily build consistent large-scale synthetic natural environments to examine vegetation clutter requirements necessary to accomplish distributed mission training tasks.This dissertation presents and implements the GENETICS algorithm, compares it against other vegetation placement schemes, and outlines how simulationists can use GENETICS to quickly and cheaply build large-scale natural environments. It also touches upon level of detail algorithms, ecotype modeling and how GENETICS can be used to generate land cover data where none exists. NUMBER OF PAGES 169 SUBJECT TERMS
