Coleta e Persistência de Informação Geográfica Voluntária

Volunteered geographic information VGI has gained visibility due to the variety of applications that can benefit from its use, including environmental monitoring, tourism, security, biodiversity, agriculture, among others. Although widespread, there is a lack in the literature on technical details of mobile VGI applications. The objective of this work was to demonstrate the development of a mobile VGI application, focusing on collection and persistence of this data type, including digital media. For this, an APP was developed. MySQL Spatial and MongoDB databases were evaluated for read and write latency. The work details the development of the APP, listing the requirements, justifying the choices and illustrating code; and presents the results of the performance tests, demonstrating that for small VGI applications, MySQL Spatial can be a good alternative as a persistence mechanism.
