美国国家地理情报局报告 - 从地图到模型

美国国家学术出版社（National Academies Press， NAP）免费提供了美国国家地理情报局（National Geospatial-Intelligence Agency，NGA）发布的报告
From Maps to Models - Augmenting the Nation's Geospatial Intelligence Capabilities (2016)，大小约为72M，文后附有百度网盘下载方式。

主要介绍了用于理解真实世界的不同模型和分析方法，讨论了将这些模型和方法用于地理空间智能还需要什么，以及美国国家地理情报局所需要支持的研究和进展。

摘取书中的几幅图作为介绍

• NGA工作场景

• 海盗袭击风险图（连这都能做，厉害了word哥！）

• 全球疟疾流行特征变化（1900 vs 2007）

• 气象模型演化

• NGA用到的广泛数据

• 两个主要的超级计算机架构，左侧数据密集型，右侧计算密集型

• 社交网络建模工具链（可惜国内上不了twitter）

Description

The United States faces numerous, varied, and evolving threats to national security, including terrorism, scarcity and disruption of food and water supplies, extreme weather events, and regional conflicts around the world. Effectively managing these threats requires intelligence that not only assesses what is happening now, but that also anticipates potential future threats. The National Geospatial-Intelligence Agency (NGA) is responsible for providing geospatial intelligence on other countries—assessing where exactly something is, what it is, and why it is important—in support of national security, disaster response, and humanitarian assistance. NGA’s approach today relies heavily on imagery analysis and mapping, which provide an assessment of current and past conditions. However, augmenting that approach with a strong modeling capability would enable NGA to also anticipate and explore future outcomes.

A model is a simplified representation of a real-world system that is used to extract explainable insights about the system, predict future outcomes, or explore what might happen under plausible what-if scenarios. Such models use data and/or theory to specify inputs (e.g., initial conditions, boundary conditions, and model parameters) to produce an output.

From Maps to Models: Augmenting the Nation's Geospatial Intelligence Capabilities describes the types of models and analytical methods used to understand real-world systems, discusses what would be required to make these models and methods useful for geospatial intelligence, and identifies supporting research and development for NGA. This report provides examples of models that have been used to help answer the sorts of questions NGA might ask, describes how to go about a model-based investigation, and discusses models and methods that are relevant to NGA’s mission.
