The convention of the Inter-Municipal Cooperation of the Local Authorities (L.A.s) of Grammos – GRAMMOS.NET was signed on December 6th, 2005, by the Municipalities of Agia Triada, Nestorio, Mesopotamia, Akrites and the Communities of Grammos, Arrennes and Kastrakio.

grammos.net is the frontend portal of a larger infrastructure. Every part of the cooperation has locally installed software for editing and updating all the geographical data of their area of responsibility. A middleware collects all the information coming from each part, integrates it, and illustrates it through a web GIS application totally developed by KissMyButton.
