知识点讲解

NO.PZ2022120703000077

问题如下:

Using geospatial data to track deforestation is best described as an example of:

选项:

A.big data analysis.

B.real-time dynamic analysis.

C.resource, supply, and operational risk mitigation.

解释:

B is correct because "the analysis at the frontiers of data science is being extended to real-time analysis. For instance: using geospatial data to track de-forestation; mining; construction; shipping; and traffic; or using natural language processes to track social sentiment on the internet."

A is incorrect because big data analysis is described as "ESG data sets ... being used by algorithms and natural language processes to determine company quality, reputational risk and many forward-looking aspects of business strength and valuation."

C is incorrect because "assessment here is not only at a company level, but can be carried out at a systems or sector level. This would include assessments of supply chain risk (e.g. from forced labour or supply constraints) or policy changes (e.g. on carbon pricing or water usage)."

这个知识点中没有提到AC选项吗?能再详细解释B选项吗?

嗨,努力学习的PZer你好:


这个知识点涉及到使用地理空间数据追踪森林破坏,其被归类为实时动态分析(选项B)的一个例子,原因是这种分析利用了数据科学前沿的实时分析能力。这里,地理空间数据的使用可以追踪森林破坏、采矿、建设、航运和交通等活动,展示了如何利用最新技术实时监测和分析地球表面的变化。


B选项解释:

实时动态分析指的是能够即时收集、处理并分析数据的能力,以便于快速做出决策或获得见解。在使用地理空间数据追踪森林破坏的上下文中,这意味着通过从卫星图像和其他地理信息源实时获取数据,能够监测到森林覆盖率的变化,从而追踪破坏活动。这种方法允许科学家、政策制定者和环保组织在森林被大规模砍伐或退化之前及时了解情况并采取行动。


A选项和C选项为何不正确:

  • **A选项(大数据分析)**虽然涉及处理大量数据集来获得洞见,但这个选项过于宽泛,没有准确指向题目中使用地理空间数据进行实时监测和分析的特定场景。大数据分析可以包括各种类型的数据分析,不仅限于实时分析。
  • **C选项(资源、供应和运营风险缓解)**更偏向于评估和管理与资源、供应链和运营相关的风险。虽然使用地理空间数据可以帮助识别和缓解这些风险(例如,通过监测森林破坏影响生态系统服务),但题目描述的场景主要是关于通过实时分析监测环境变化,而不直接关联到风险管理的策略或操作。
