%X 地震应急期间,标准清晰的专题图因其快速、直观、信息量大等优点,能及时有效地提供灾区基本情况和灾情信息,在地震灾害应急指挥及救援管理中发挥着重要作用。地震应急图件的制作流程涉及基础数据的处理、总体设计、符号设计、制图综合、打印出图等多个环节,甘肃省地震应急专题图存在应急图件制作不规范、产品产出时效性不高的问题。通过不同比例尺数据库的建立、地震应急专题图和产品目录的设计、专题图模板的制作、本地化快速出图软件的部署,使震后应急期间各类专题图件产出快速、标准化、产品化,使甘肃省地震应急快速制图的能力和水平得到提升。<br>An earthquake emergency thematic map highlights and, as exactly and in as much detail as possible, displays one or more thematic elements in an earthquake-stricken area. Compared with an ordinary map, an earthquake emergency thematic map shows not only the current status and distribution of various elements of the earthquake area but also illustrates the dynamic change and development laws of various elements during the earthquake emergency rescue such as the dynamic changes of relief efforts after the earthquake, the distribution of relief supplies, and changes in the geological disasters. Earthquake emergency thematic maps includes maps of the earthquake, population, economy, traffic, housing estates, schools, hospitals, and geological hazards. During an earthquake emergency rescue, the earthquake emergency thematic map acts as an important output that allows an earthquake emergency office to respond effectively. It serves as one of the main basic maps to aid the government to take control and make decisions playing an important role in earthquake emergency rescue operations. A standardized and clear thematic map plays an important role in earthquake emergency command and rescue management providing timely and effective basic and disaster-related information. Its advantages are in providing rapid, visual, and large quantities of data. The computer mapping process of the earthquake emergency map involves basic data processing, overall and symbol designing, cartographic generalization, and map printing. In Gansu province, the available earthquake emergency maps were not standardized resulting in no timely output. In this study, we first classified, sorted, and preprocessed data from the earthquake emergency basic database of Gansu province (data transformation, topology error check, attribution edit, and others). Next, using the earthquake emergency thematic map concept as the basis, we built databases of different scales (50000), drew 16 thematic maps, and designed a product catalog in accordance with actual seismic demand. Then, we drew the Gansu province thematic map by region and divided the template into eight different magnitudes according to the seismic intensity attenuation relationships in Gansu province. Finally, we used fast-drawing software to rapidly output earthquake emergency
