The IBGE has just released 36 digital image maps in the 1:100,000 scale (1 cm = 1 km), comprising part of the states of Piauí, Bahia, Pernambuco, Ceará and Maranhão. These cartographic products consist of mosaics of satellite images. Distortions have been eliminated, in order to render the image metric and free from errors associated to its acquisition. With this release, Piauí now has all its territory represented. The files in PDF format can be accessed here.

The maps provide a view of the territory, consistent with the representation requirements of this scale, showing the name of the localities and geographic elements of higher relevance, like waterways and mountains. The production of maps takes less time than that of complete topographic sheets, making this information quicker available to the society. 
The maps were produced from the images of the AVNIR-2 sensor, provided with a 10-meter spatial resolution, most of them acquired between 2009 and 2010. They comprise the Cartographic Base in the 1:100,000 scale Project (BC100) and correspond to one of the products scheduled for the Federation Units. With this release, Piauí now has all its territory represented, which corresponds to a total of 108 image maps.
