IBGE published a series of vector digital files (shape files that can be handled by users), as a result of the surveys on Land Use and Cover in Rondônia and on Surface and Groundwater Hydrogeology and Hydrochemistry in the Northeast Region. These and other maps can be accessed on link http://mapas.ibge.gov.br/en/.

The Land Use and Cover map of Rondônia details the file released in 2013 with a scale of 1:1,000,000 (1cm = 10km). Now it is presented in vector format with a scale of 1:250,000 (1cm = 2.5km), so as to allow the users to better handle it. The access is on link  ftp://geoftp.ibge.gov.br/mapas_tematicos/uso_da_terra/unidades_federacao/shape/RO/.

Also in vector format, the maps of Hydrochemistry of the Surface and Underground Springs and the Hydrogeology Map of the Northeast Region allow users to better handle them. They were originally released in PDF format in December 2013, with a scale of 1:2,500,000 (1cm = 25km).

The three maps bring information on aquifers and on the quality of surface and groundwaters in this region. As the most deprived region in terms of water resources, the maps will provide data for planning and rational use of water resources. The access link is ftp://geoftp.ibge.gov.br/mapas_tematicos/recursos_hidricos/regionais.

All the maps will be soon available for consultation at the INDE website - National Spatial Data Infrastructure, on link www.visualizador.inde.gov.br.
