地理信息系统 (GIS) 内的互操作性涉及数据和操作。我们在这里关注数据方面，更具体地说，关注对多个、分布式、异构和自治信息源的访问及其集成。为此，我们需要考虑处理地理空间数据的应用程序的特殊要求，例如：考虑的海量数据；复杂且高度结构化的数据的存在；多种不同地理格式的共存；全球范围内地理数据重用的趋势日益增强；地理数据的分布式性质。
Interoperability within geographic information systems (GIS) is concerned with both data and operations. We focus here on the data aspect, more specifically on the access to multiple, distributed, heterogeneous, and autonomous information sources and on their integration. For this purpose, we need to take into account the special requirements of applications dealing with geospatial data, such as:the vast amounts of data considered;the existence of complex and highly-structured data;the co-existence of many different geographic formats;the increasing trend towards reuse of geographic data all over the world;the distributed nature of geographic data.
