Coleta e Persistência de Informação Geográfica Voluntária

Volunteered geographic information - VGI has gained visibilitydue to the variety of applications that can benefit from its use, includingenvironmental monitoring, tourism, security, biodiversity,agriculture, among others. Although widespread, there is a lackin the literature on technical details of mobile VGI applications.The objective of this work was to demonstrate the development ofa mobile VGI application, focusing on collection and persistenceof this data type, including digital media. For this, an APP wasdeveloped. MySQL Spatial and MongoDB databases were evaluatedfor read and write latency. The work details the development of theAPP, listing the requirements, justifying the choices and illustratingcode; and presents the results of the performance tests, demonstratingthat for small VGI applications, MySQL Spatial can be a goodalternative as a persistence mechanism.
