Validação com proposta de extensão do modelo de dados geográficos MGeo+.

Abstract

This work had as main objective the validation of the Conceptual Model Geographic Data Collection +. from a real case study and relatively complex. The case study developed in the context of the agricultural suitability survey of the soils of the eastern sector of the Seridó River basin (PB). Validation consisted of mapping soil characteristics (physical, chemical, morphological, climatic and pedological properties) in model classes. As a result. concluded by extending the model of to include the temporal aspects of the data. To this end, the work presents the main concepts related to temporal space data modeling and concludes with an extended model analysis, TMGeo, based on in its potential to respond to a comprehensive set of queries spacetime.
