Between the Tavoros and the Achelous rivers, two parallel mountain ranges extend, the western and eastern Agrapha, with the Agraphiotis river flowing between them, a tributary of the Achelous. The western Agrapha form a narrow ridge with the highest point being the rugged Fteri at 2126m, along with two shorter branches that embrace the two wildest valleys of the entire complex: the valley of AsprOrema and that of Fteri.

The eastern Agrapha are longer and more branched. They form a cluster of impressive peaks to the north, including Borlero, Plata, Flitzani, and the Five Towers (see the map of northern Agrapha), while their highest peak, Svoni, overlooks the famous grazing area of Nialas.

The "Topo" series represents the latest step in the long journey of cartographic development by "Anavasi". The "Topo" series includes maps at scales of 1:100,000, 1:50,000, 1:25,000, and 1:10,000. The maps are constructed using the Hellenic Geodetic Reference System (HGRS 87), the national geodetic system implemented to meet the needs of large land registration and mapping programs in the country.

"Anavasi" strives to provide the best and most accurate cartographic material. Thus, all tasks (base construction, data collection and field recording, final map composition) are carried out with defined and strict quality and fidelity specifications, ensuring the maximum possible accuracy for these specific scales.

In the "Topo" series from "Anavasi", two coordinate systems appear: - The grid of squares every 1 km in the Hellenic Geodetic Reference System. It is a complete rectangular grid (orange lines). The projected coordinates of the HGRS are expressed in meters. - The crosses of geographical coordinates every 1 minute in WGS84. These are the intersection points of the meridians and parallels of the global geodetic reference system projected onto the map. If you are using the map in conjunction with GPS, you can locate your position based on the coordinates provided by the GPS without changing any of its settings.
