Analyzing these enormous volumes of disparate data on mobile devices requires context-aware smart applications and services. 3DQ (Three Dimensional Query) is our novel mobile spatial interaction (MSI) prototype for data mining and analysis on today's location and orientation aware “smartphones” within such 3D sensor web environments. Our application tailors a military style threat dome query calculation using MSI with “hidden query removal” functionality to reduce information overload and heighten situation awareness on these commercial off-the-shelf (COTS) devices. Allied MSI research into the information overload problem is ongoing, where map personalisation and other semantic based filtering mechanisms are essential to de-clutter and adapt the exploration of the real world to the processing/display limitations of mobile devices. We propose that another way to filter this information is to intelligently refine the search space. The combined effect gives a more accurate and expected query (search) result for Location-Based Services (LBS) applications by returning information on only those objects/sensor enabled “things” visible within a user's 3D field-of-view (FOV) as they move through a built environment.","PeriodicalId":259976,"journal":{"name":"2012 20th International Conference on Geoinformatics","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126677000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the alternation between agriculture land and grass land and the factors which cause those changes could provide scientific basis for the protection of regional environment. Based on the technology of RS and GIS and meteorological data during 1959~2008 and land use data from 1956 to 2008. This paper analyzed the changes from the number of agricultural and pastoral land, spatial variation, gravity center and density during 1956 - 2008. And analysis the factors which cause those changes deeply. The results showed that from 1956 to 2008, the arable land in this area increased by 4.61 × 105 hm2, while pastoral land decreased by 7.65 × 105 hm2. The frequency of alteration between arable and pastoral lands increased, their gravity center inclined to the west and opposite in latitudinal direction. Density of about 10% of grassland is widely distributed, and arable land of 20% - 30% is mainly in the eastern. Interaction between agricultural and pastoral land is caused by both climatic and human factors. Climatic factors are the main driving force, but human activity also played a negligible role.","PeriodicalId":259976,"journal":{"name":"2012 20th International Conference on Geoinformatics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126677679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We review the progress in fire spread simulation and virtual forest modeling, and present a 3D forest fire spread simulation and visualization system. Methods and techniques for modeling and visualization of terrain, trees and vegetations and fires are discussed and incorporated with fire spread simulation and visualization system. An integrated environment was built based on OntoPlant, a suite of virtual plant software developed in house, FARSITE fire simulator developed by the USDA as fire spread engine and Open Scene Graph (OSG). The system can display a realistic 3D wildfire scenario taking into consideration the factors such as terrain, vegetation type and weather conditions. Fire is rendered by using particle system, while the level of detail and curve morphing technique are used to animate the flame and smoke under various slope and wind conditions. During the fire propagation, the appearances of burned plants are updated automatically. The fire spreading is visualized according to the calculations derived from the fire simulation engine. Greater insight can be gained as users realistically and intuitively view the fire progress in our 3D virtual forest environment.","PeriodicalId":259976,"journal":{"name":"2012 20th International Conference on Geoinformatics","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128664003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two Landsat images were used to detect the change in potential crane habitat, from which suitable crane habitat was determined by excluding behaviorally and physically fragmented areas. It is found that suitable habitat decreased by 5,105 ha in spite of the increase of 4,747 ha in potential habitat during 1992-2008. Natural and anthropogenic forces exerted an almost equal influence on habitat change. Retrogressive succession accounts for 41.9% of the change arising from natural factors. By comparison, land use, the predominant anthropogenic factor, is responsible for 83.6% of the total human-induced change. Although the Yellow River flow has been diverted to the degraded wetlands since 2002, such an effort has not restored the habitat quality to its 1992 level due to physical fragmentation and intensified human disturbance. Thus, complementary restoration efforts should aim at implementing commensurate measures to rationalize the spatial allocation of reed marshes and water, and curbing anthropogenic influences inside the Reserve.","PeriodicalId":259976,"journal":{"name":"2012 20th International Conference on Geoinformatics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128211917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finding out the possible positions of environmental hazards is very important because it can help researchers to identify the causes of environmental hazards and furthermore to remove them. However, it is not an easy task without the help of computers because the amount of information people must handle and analyze is massive in modern society. In order to help to find out hazards by computers, many models and algorithms are designed. For example, analysis of clusters of diseases is an important method. However, current cluster analysis methods ignore mobility of people, which is an important feature of modern society. Therefore, the methods cannot pinpoint the exact areas responsible for the development of a disease and how much possibilities hazards appear in the areas. In this paper, we propose novel models and algorithms based on the patients' residential history, mobility of locations of people and disease principles. Our models and algorithms differ from previous ones in the following ways. First, we consider more complex situations such as multiple hazards and outliers and so on. Second, our algorithms not only output the possible areas responsible for diseases but also output the how much possibilities hazards appear in the areas.","PeriodicalId":259976,"journal":{"name":"2012 20th International Conference on Geoinformatics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133248905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dianchi watershed in which Kunming city is located also experienced the serious deterioration of ecological system from the late 1970s. In search of a viable way to coordinate between urban growth and protection of freshwater lake, objective of this paper is to monitor land use/land cover change of Kunming city through the methods of Remote Sensing (RS), Geographic Information System (GIS), spatial metrics and Moran's I. index. The results show that land use/land cover change in Kunming city is characterized by the sprawl of urban built-up area and the decrease of agricultural land. Urban built-up area has gradually replaced agricultural land to be the most dominant land use type in the study area. Urban growth of Kunming experienced a “clustered-dispersed-clustered” process, sprawling like an expanding pancake. There is very limited space for urban built-up area to further expand. Upon the analysis of the aspects that affect the sprawl characteristics, several useful suggestions were made for the authority and planners.","PeriodicalId":259976,"journal":{"name":"2012 20th International Conference on Geoinformatics","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133541759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
