军事地理信息系统构想与空间决策分析 总被引：1，自引：0，他引：1
田波 《地球信息科学学报》2004,6(1):76-80
地理信息系统具有强大的空间分析功能,因此其在军事领域中,特别是同武警部队执勤、处突和反恐怖任务结合起来,综合地、动态地获取、管理和分析区域内地理环境信息及军事专题属性信息,服务于执勤、处突环境分析和辅助决策的指挥自动化应用系统,充分发挥其效益,是一种尝试。基于地理信息系统软件ArcView3.2,武警北京总队军事地理信息系统演示系统突出强调了网络分析功能、地图绘制功能及三维模拟分析功能;系统主要由最佳路线、机动支援、空间分析、制图绘图、三维模拟及卫星影像6个子功能模块组成,实现了北京地区二环线内武警机动部队的最佳路线、最近设施的选择、军事地图的绘制与输出、北京天安门地区的三维模拟显示。该演示系统能为指挥自动化系统进行辅助决策提供地理信息保障,实现北京地区的军事地理信息互通及共享,提高工作效率,节约人力物力资源。 相似文献

警用视频监控的犯罪防控效果及空间差异 ——以苏州市姑苏区为例 总被引：3，自引：2，他引：1
采用双重差分法,对苏州市姑苏区2014~2016年的警情数据进行分析,评估警用治安视频监控的犯罪防控效果。结果表明,视频监控对犯罪具有明显的抑制性作用。在案件类型上,视频监控对盗窃类案件的防控效果较好,但对盗窃电动自行车、盗窃电动车电瓶的防控效果较小。在时间维度上,与节假日相比,对工作日犯罪的抑制效果更好;与晚上相比,对白天犯罪的抑制效果更好。针对通过局部空间自相关分析所获取的重点区域,与警务人员访谈和实地调研后发现,视频监控的犯罪防控效果与周边地理环境、人流密集程度、警务情况等密切相关。 相似文献

Despite widespread interest in the relationship between the exercise of power and control of space, few current works in geography make explicit use of the concept of territoriality. This paper does so by considering the means by which the Los Angeles Police Department pursues its law enforcement and order maintenance functions through regulating space. I draw upon fieldwork observations of a single LAPD patrol division to demonstrate that officers regularly seek to govern the citizenry through controlling the spatial parameters of permissible action. The imperative toward effective territorial control is given further impetus within the subcultural world that officers construct; indeed, officers evaluate each other's competence in large part on their ability to manage activity within the spaces for which they are responsible. 相似文献
