Municipalities facing the sea

Description

The product derives from the updated Digital Municipal Mesh. The IBGE revises it annually as it is a basis for its Surveys and Censuses. The new version replaces that of 2015, in compliance with item I, of of Article 4 of Section I of Chapter II of Decree 5300 of December 7, 2004, which determines that the IBGE prepare a list of coastal municipalities (“...municipalities facing the sea, as defined by a list made by the Brazilian Institute of Geography and Statistics Foundation – IBGE…”).

Technical Information

Technical Note

The coast line described here does not intend to portray the average tide line or the influence of the coastal dynamics, or even to cover the typical contours of our coast (bays, deltas or other estuary-lagoon systems); neither does it result from fluvial-marine erosion studies.

For what it is worth, this study has nothing to do with the list of municipalities with a direct influence on the phenomena taking place in the coastal area as described by the MMA in Ordinance No. 461, of 12/13/2018. Moreover, this product must not be used as a reference for the analyses of Decree 93.189/86, which regulates the tracing of the projected borderlines between the land areas of states and municipalities and the sea facing them.
