Framed within the Open Government and Open Data initiatives and supported by data sharing and interoperability platforms at different administrative levels, the use of spatial data in the provision of e-government services strongly increased in recent years. Better understanding these practical implementations of spatial data contributes to the effective development of Spatial Data Infrastructures (SDI) that promote and facilitate the accessibility of spatial data. This paper introduces an in-depth review of the state-of-the-art applications of spatial data based on a literature review of scientific papers and articles on related topics. For the elaboration of this state of the art, the systematic review was used with the PICOC criteria commonly used for such purposes. Five databases of indexed papers of the first order were reviewed emphasizing the implementations of spatial data and open spatial data in both Ecuador and Peru.
