GIS-TFC: A GIS FOUNDATION CLASS LIBRARY

该项目将开发一个基础类库，用于构建适合公共卫生数据分析的地理信息系统。第一阶段将实施GIS- tfc库，并将其应用于创建一个卫生GIS原型，以证明项目的可行性。第二阶段将全面实施基础类库，将其作为软件开发工具加以记录，并通过开发一个卫生地理信息系统示例进行演示。第一阶段的目标是：(1)使用基于数据模型和应用程序级别考虑的对象设计开发基础类库。(2)实现应用程序程序员在设计时可访问的查询结构。(3)通过使用GIS- tfc作为快速应用开发工具来实现原型卫生GIS，评估项目可行性。目前现成的GIS缺乏卫生GIS所需的关键功能。本项目开发的基础类库将满足这一需求。拟议的商业应用：目前可用的地理信息系统软件包缺乏社区和公共卫生应用所需的专门功能。我们将开发的库使应用程序程序员可以访问底层数据模型和查询结构，为构建生物医学GIS软件提供前所未有的灵活性。

This SBIR project will develop a foundation class library for constructing Geographic Information Systems suited for the analysis of public health data. Phase I will implement the GIS-TFC library and apply it to create a prototype health GIS in order to demonstrate project feasibility. Phase II will fully implement the foundation class library, document it for use as a software development tool, and demonstrate it by developing an example health GIS. The Phase I objectives are: (l) Develop the Foundation Class Library using an object design founded on both data model and application level considerations. (2) Implement a query structure accessible at design-time by application programmers. (3) Evaluate project feasibility by using the GIS-TFC as a Rapid Application Development tool to implement a prototype health GIS. Today's off-the-shelf GIS lack critical functionality required of health GIS. The Foundation Class library developed by this project will fill this need. PROPOSED COMMERCIAL APPLICATIONS: Currently available GIS packages lack the specialized functionality required by community and public health applications. The library we will develop makes the underlying data model and query structure accessible to application programmers, providing unprecedented flexibility for constructing biomedical GIS software.
