Head of the Peloponnese, although now separated along with Ilia in the region of Western Greece, Achaia is blessed with all the good things of the Peloponnesian land. Fertile plains and well-formed mountains create beautiful and serene landscapes offered for travel throughout the year.

The "Topo" series represents the latest step in the long evolution of the cartographic work of "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 made using the Greek Geodetic Reference System (EGSA 87), the national geodetic system that was implemented to meet the needs of major land registration and mapping programs in the country.

Considering that a map is a tool on which the user's safety sometimes depends, "Anavasi" strives to provide the best and most accurate cartographic material. Therefore, all processes (production of backgrounds, collection and recording of field data, final cartography) are carried out with defined and strict quality and fidelity specifications, ensuring the maximum possible accuracy for the specific scales.

In the "Topo" series of "Anavasi", two coordinate systems are presented:

• The grid system at 1 km intervals in the Greek Geodetic Reference System. It is a complete rectangular grid (orange lines). The projective coordinates of the EGSA are expressed in meters.
• The intersections of geographical coordinates at 1 first minute in WGS84. These are the intersection points of meridians and parallels of the global geodetic reference system projected onto the map.

If you use the map in combination with GPS, you can locate your position based on the coordinates provided by the GPS without changing any settings.
