Abstract Geographic information system (GIS) is widely used to solve the problems about spatial decision making and strategy planning. However, the potential application in maritime search and rescue (SAR) strategic planning still needs to be opened up. With the theory of accessibility, a new evaluating model of maritime SAR ability was proposed to assess the efficacy of the SAR unit serving a certain sea area by using a key indicator named virtual probability circle (VPC) which stand for the extent of how difficult or how long the SAR vessels reaching the accidental site. In this article, an application to the South China Sea area is shown. Comparing with the SAR abilities before and after new bases settled, the results indicate that the model provides good opportunities for improving maritime management.

Aid Decision

This work aims to create a decision support and geographic information system aimed at optimizing the management of forest capital in the Adrar region. Through this awareness, we question the place of geographic information in the dialogue process and the approach to sustainable development. Cadastral data, satellite images, cartographic and photographic data will be presented. Data processing and data integration will be discussed. The expected results must provide knowledge beyond reach without these tools. They clarify the importance of satellite images and the spatial component of geographic information. In the current context of sustainable development, geographic information appears necessary for decision-making.

Energy and mining reporting have to conduct for the exploration company in order to make control while exploration. Government control can perform by making profiling of energy and mining data that exist in the area as consideration in taking policy or decision. Stages of energy and mining reporting are very important to do especially in areas that have energy and mining resources such as Musi Banyuasin regency. Profiling can performed by mapping the location of energy and mining results using a geographic information system (GIS) to organize data between explorers and governments. Based on these conditions GIS was developed using a technique that prioritizes user needs with extreme programming development techniques. The result of GIS development shows that the processing of data becomes information based on spatial and non-spatial data with the final result of energy and mining report. The report presented can be used as a report to the relevant parties as an effort to open data of energy and mining as material in decision-making or policy. Geographic information system generated systematically developed using extreme programming approach with five stages of exploration, planning, iteration, production and maintenance so that it can run funtionaly according to its function

The concept of ‘resilience’ breaks down silos by providing a ‘conceptual umbrella’ under which different disciplines come together to tackle complex problems with more holistic interventions. Acknowledging the complexity of Davoudi’s approach (2012) means to recognize that ‘spatial resilience’ is influenced by many phenomena that are difficult to measure: the adaptation and transformation of a co-evolutive system. This paper introduces a pioneering approach that is propaedeutic to the spatial measure of urban resilience assuming that it is possible to define a system as being intrinsically vulnerable to stress and shocks and minimally resilient, as described by Folke in 2006. In this sense, vulnerability is counterpoised to resilience, even if they act simultaneously: the first includes the exposure to a specific hazard, whereas the second emerges from the characteristics of a complex socio-ecological and technical system. Here we present a Geographic Information System-based vulnerability matrix performed in ESRI ArcGIS 10.6 environment as an output of the spatial interaction between sensitivities, shocks, and linear pressures of the urban system. The vulnerability is the first step of measuring the resilience of the system by a semi-quantitative approach. The spatial interaction of these measures is useful to define the interventions essential to designing and building the adaptation of the built environment by planning governance. Results demonstrate how mapping resilience aids the spatial planning decision-making processes, indicating where and what interventions are necessary to adapt and transform the system.

In modern society, informationization is becoming more for the lasting development of tourism. The design and application of Tourism Information System (TIS) is an important power to pull tourism development, then it’s very important to strengthen the constrution of TIS. WebGIS is an very important trend of Geographic information system (GIS). It not only has the general characteristics of GIS, but also has the special characteristics of Internet, thus it becomes the first platform for TIS. With the help of WebGIS, tourism enterprises can improve the management efficiency and service leve. In this paper, the research status of TIS at home and abroad has been discussed, the characteristics and functions of WebGIS has been analysed. Finally, according to the tourism characteristics of Chongqing city, the tourism information was divided into several typies, and then the design of space database，property database and Decision-making support systems has been analysed.
