As an important information source, DEMs (Digital Elevation Models) have found applications in a wide variety of areas, such as view shed analysis, watershed partition, derivation of geomorphic features, etc Assessing the accuracy and quality of DEMs scientifically will assure the production, construction and right applications of DEMs. Except factors of data sources, instruments and man made, the major error of DEM roots in interpolation arithmetics. So,the assessment of the accuracy of DEMs is a kind of error analysis aiming at the interpolation accuracy mainly There exist two methods that have the specific theoretical context and accuracy analysis among numerous methods to generate DEMs. One method is TIN (Triangulated Irregular Network) interpolation based on discrete ground elevation points, the other is bilinear interpolation used for grid ground elevation points obtained by photogrammetry. This paper gives error models of the above two interpolation methods. The two error models explain some problems that can't be interpreted using RMSE. Nowadays, the two methods to generate DEMs have a wide range of application in practical DEMs productions. Both have own advantages and application fields At present, there are major methods to assess the accuracy of DEMs: test, transfer function, covariance and contour maps produced from DEMs. For test method, the sampling check points lack rigorous theoretical basis. While both methods of transfer function and covariance have difficulty to assess the accuracy of the whole DEM and render the factual distribution of errors,they also can’t estimate the status of the DEM coinciding with the factual topography. In the situation of lacking a valid theoretical accuracy assessment about DEMs presently, contour maps produced from DEMs serve as a natural method to evaluate the quality of DEMs. In fact, as long as the method applied to DEMs interpolation is right, the maximal difference of the original topographic map and the map generated from the corresponding DEM will be less than a half of the numerical value of contour-interval. And the overlay map of the original topographic map and the map obtained from the DEM is just an elaborate render of the whole DEMs error In a word, assessing the accuracy of DEMs rightly is of momentous practical significance and theoretical value. We must adopt truncation error to assess the accuracy of DEM abandoning RMSE. Comparison of the original topographic map with the map generated from the DEM is the most effective method to check the quality of DEMs.

Geographical network modeling emphasizes the network topology between the nodes and links withinthe logical networks and the semantic manipulation process.But the classical GIS vector data representation isbased on planar graph primitive arc-node data models,which emphasizes geometrical representation.In this paper,the authors introduce a feature based GIS conceptual modeling method to break through the restriction of planar enforcement.To this end,a feature based geographical network model is developed and the characteristics and application issues are discussed.The author separates the network topology from the geometrical dataand argues that network topology is not always dependant on geometrical data although different copies of network topologies can be derived from a same geometrical network.Geographical network topology is differentfrom geometrical topology.Most of network modeling and analysis is based on derived network topology.For theimplementation of geographical network,the integration of object oriented methods and database technologies isfirstly discussed,the difference between classical relational models and object oriented models is then comparedin geographical network representation,and the advantages of object oriented methods for geographical networkroute system representation,dynamic segmentation,and network connection rules are analyzed lastly.It is argued that the feature based object oriented approaches are powerful for complex network modeling and deservesdetailed research and development in network operators,extended structural querying language,and multi-scaledatabases implementation.

Mining the association rule from the database appeared the first in the commercial field. In the mid 1990’s, the geo-association rule was promoted. Geo-association means that the spatiotemporal relationship between the geographic events, which can be used to reasoning one spatiotemporal geographic event or event combination from another event or event combination. Based on the review for the research background and development of geo-association rule, the geo-association rule can be categorized by its complexity as spatial characteristic rule, spatial discriminate rule, spatial association rule and spatiotemporal association rule. With the definition of spatiotemporal rule by mathematic language, the effect of the different indices on the rule mining is analyzed. Furthermore, the presentation analyses the data processed in the rule mining with the level of generalization, the data dimension, the variable type and spatial topologic relationship respectively. The geo-association rule can be categorized as single level rule or inter-level rule by the level of generalization, as one-dimension or multi-dimension rule by data dimension, as boolean or numeric rule by the variable type, as local or focal rule by the topologic relationship. Finally, the presentation describes the flow to forecast the fishing ground using the geo-association rule.

Raw images obtained by whatever earth observation systems are the comprehensive reflection of magnetic spectrum characteristics of surface objects The primary images produced through systematic processing in remote sensing ground station still contain various errors in geometry and radiation because of the influence of atmospheric and topographic conditions And the information from various objects mixes together and influences each other Therefore, what the primary image provides is only data instead of information This data must be reprocessed to get high quality image and useful information suitable to different special applications However, the specialties of most researchers who are engaged in remote sensing image processing are computer, electronics etc They have not enough knowledge in application fields and can’t understand well the rich and valuable information which the remote sensing data of different sensors and different dates contains Apparently, even an excellent expert on image processing can’t complete processing tasks effectively to meet the demands of various applications Thus, up to now, the huge and valuable remote sensing data haven’t been used fully and effectively We think that the remote sensing image processing should be divided into two parts, systematic processing and application processing They are two parts of remote sensing processing, being both closely related and differing from each other The purpose of systematic processing is to improve the quality of image on the whole While that of application processing is, according to concrete application purpose and task, to carry out the comprehensive and object oriented processing so as to analyze and extract thematic information accurately and effectively This paper discussed the general method and procedure of remote sensing image application processing, and showed some successful examples of using it in forest fire detecting, rapid response of flood, city expansion investigation, soil resource survey and management, and dynamic monitoring of landuse.

Nowadays, the pollution of groundwater has become more and more serious. There are many pollution sources such as fuel, garbage, agriculture and industry related wastes. Because of lack of fresh water,groundwater has been over extracted. Therefore, changes of groundwater including quality, quantity, pH, temperature and water level should be monitored. To satisfy this need, we developed groundwater monitoring system based on distributed bus and sensor technology. This system can give us multi-parameter digital display and remote communication. We also used the HTG method in automatic measurement of groundwater quantity. Many other sensors have been used in detecting the other characters of groundwater. We designed a multi-access device to collect the signals from all kinds of sensors. After getting all the parameters, we transmitted these signals back to the computer by RS-485 distributed bus. The application software running on the computer uses the specific algorithm to process all the data, then changes of groundwater are displayed immediately. So the inspectors can know the situation and make corresponding decisions. The practical use shows that the system has satisfactory performance and good application result.

The coding scheme for classifying House Property thematic geographic information is the bedrock of House Property information management and information application,and that really determines whether or not you succeed in information system construction. If the established coding scheme is illogical，it will increase workload in building a geo-database and do great harm to the use of database or data sharing. It even can shorten the database lifecycle and we will suffer huge loss. Thereby,perfect coding scheme for classifying House Property thematic geographic information is very crucial to achieving system and data management and data application goals. With the help of the experience in requirement analysis and data integration,parts of “Digital House Property” sharing platform of Nanjing Project,and in consideration of the need of information sharing across departments and cities,the writers put forward a coding scheme for classifying House Property thematic geographic information. We expected that is a rewarding work on geographic information standardization of House Property.

There are many papers about the relationship between satellite thermal infrared anomaly and earthquake in the world, but most of them study thermal anomalies of surface and air of focus region We could predict earthquakes not only by temperature anomalies of satellite thermal infrared imageries, but also by special abnormities appearing on satellite thermal infrared imageries The special abnormities are produced by stochastic resonance near antenna between background noise,electromagnetic wave from strong earthquake and carrier wave that transmits satellite data They include black holes and diamonds by disturbance The blackholes are black areas of satellite imagery because the standard location table is disturbed The diamonds are white enclosed diamond line on satellite imagery when isolines of temperature are showed because the standard temperature table of gray rank is disturbed They are not real temperatures of cloud layers, and they can appear on the cloud layers that the temperatures are lower or higher The reason for disturbance is because electromagnetic waves are produced by geo stress action during earthquake preparation They have very wide frequencies If the frequency and strength is about carrier frequency near receiving antenna of satellite, it can produce stochastic resonance and result in disturbance of receiving data The observation data of our receiving station in more than one and half years time show that the abnormities obviously correspond to strong earthquakes It adds one new applied field of stochastic resonance of electromagnetic wave impending prediction Through further studies, we can design one kind apparatus used for catching earthquake precursors by stochastic resonance principle.

An earthquake(M6 8) occurred on Feb 24,2003 in Jiashi and Bachu counties of Xinjiang of China This earthquake(epicenter:N39 5°and E77 2°) produced many casualties,over 2000 injured and over 200 died, as well ten thousands of buildings destroy Its occurrence shows again the importance of precise prediction Taking this event as an example, the paper raises a new technique involving 3 elements for predicting earthquake,i e ,tracking each information in element order and step by step It's process as follows:The first step is the precise judgment of seismic intensity (magnitude) According to the “Gutenberg Law”, there existed a linear relationship bet ween the different seismic magnitudes(M) and the sequence number(N),i e , “Log N = a-bM” Because the seismic actions are of self exciting characteristic, so we can base on the historic seismic information and establish a self exciting mathematical model for predicting the forth or the next time earthquake magnitud e According to the result of modeling and calculating to Xinjiang of China, we can precisely predict out that an earthquake of M5 4 will occur in Xinjiang followed by an M6 8 strong earthquake event in 2003 The second step is the precise judgment of risk region A lot of investigations show that there exists heat radiation omen before a strong earthquake,especi ally in epicentral region How to moniter this thermal omen information before earthquake for judging risk region in short term,the paper suggested to use OLR (Outgoing Longwave Radiation) information which comes from the NOAA satellite remote sensing As a result,we found that the most high value of monthly departure of OLR were present at the Jiashi epicenter region in January of 2003,and reached +21 9(W/m 2) which is not only the highest value in whole Xinjiang, but also breaks through the historic record The last step is the precise judgment of the imminent earthquake time A good many of investigations of earthquake in situ shows that the small pertubation in external factors, such as atmospheric pressure etc , can trigger the strong earthquake, especially at the imminence time We found that the pressure vari ograph (24 hours) at Jiashi epicentral region had changed +6 5(hp) on February 21,2003, i e , three days ahead of the Jiashi earthquake (M6 8) The process above mentioned is not only gradually reflecting earthquake preparat ion and evolution, but also gradually revealing it's omen features We believ e this predicting technique on line based on combining satellite remote sensing with ground information to be of far reaching importance.

Beginning from the concept and development of Geographic Information System (GIS), this paper completely and systematically introduces the developing necessities, characters and key problems of military GIS. Due to very strong spatial analysis function of Geographic Information System and it′s broad application fields, GIS should be incorporated into military field to combine with patrol, antiterrorism, dealing with emergency accidents for armed police especially so that armed police can integrate, dynamically acquire and manage all kinds of informations about military and police themes. Concurrently, the enterprise-wide need to improve organizational effectiveness, efficiency, and services of Armed Police Force to protect national benefits and life safety. GIS may be used to analyze a lot of informations on regional environment to help resolving safety problems at best speed. Moreover, based on GIS, the military command automatic application system may support decision-making and bring into play its benefits adequately. Based on Arcview, we built a military GIS Demo version of Armed Police Force, which emphasies functions of network analysis, map plotting and 3D simulation. The demo system consists of six sub-function modules such as the best route design, mobile reinforcement, spatial analysis, drawing and plotting, 3D simulation and satellite image display. Hence, the demo system realized the best route design, nearest infrastructure selection, drawing and plotting of military map, 3D simulation and display of Tian′anmen Square within the second ring road in Beijing. Furthermore, the demo system can provide geographic information guarantee for the command automatic aid system on decision making and realize connection and sharing of military information. It can improve the efficiency and save human resources and materials.

Integrated storing and accessing geographical features related information is one of the most important technologies for GIS application developments. It has been a consensus of opinion in the GIS society that storing and managing mass spatial data with current business relational database management systems under the support of extended relational models is an efficient and effective technology for developing mass data and network oriented spatial database management systems. In this paper, the authors analyzed and discussed some typical spatial database management platforms including ArcSDE, Oracle Spatial, Informix Spatial DataBlade, DB2 Spatial Extender and MySQL Spatial Extensions from the view of storing models, process management schema, spatial querying and indexing, and data cache approaches. It is argued that current business spatial data engines or extension technologies still deserve much more research and improvements, especially for topology representation within relational database management systems and application schema, adaptive spatial indexing and optimization methods, and user defined complex object representation, sharing and inter-operability.

Scenarios analyses of regional land use change, influenced by various factors, have become the hot-spots of LUCC studies. Regarding system dynamics model and CLUE-S model as the modeling framework, this paper designed a Land-Use Change System Dynamics (LUCSD) model and realized the scenario analyses of baseline, ecologically-oriented and economically-oriented models in Taips County(2000～2020). The findings are concluded that land use change is a dynamic process driven by population growth, economic improvement and farming and pasturing development, and unused land in the northeastern and northwestern parts of Taips County will be the sensitive areas of land use change in the coming nearly 20 years. Based on different scenarios models, competition between land-use types led to diversity storylines in some areas. In this sense, some effective measures should be taken to hold back the irreversible but irrational conversions among land use categories to protect the eco-environment and go along with a sustainable development in Taips County.

In the domain of surveying and mapping,users present rigorous requirement for the image quality. But there are noises in the image data,hence it is possible to perform lossy compression. In this paper,an optimum technique about remote image lossy compression based on wavelete transform is presented. First,we analyse the disadvantage of data compression based on discrete cosine transform; then we adopt the method of two-layer and two-dimension wavelete transform to decompose original image; finally,according to the characteristics of remote sensing images,optimal quantizers are constructed based on LMSE principle to meet the high quantity compression. At the same time,according to the experiment,the rough relation between the compression rate and p-p SNR is acquired.
