This article shows the improving of analysis patterns in the geographic domain through ontological meta-properties, where each pattern's class has its concept analyzed ontologically. This improvement also permits to restructure the class diagram of analysis patterns, increasing the reuse quality. Besides improving the analysis patterns, it is proposed one(More)
