Landscape TypologyLandscape Typology1. Πεδινές περιοχές (επίπεδες ή ελαφρώς επικλινείς)
1α. Πεδινές περιοχές με εκτατική ή εντατική καλλιέργεια και αγροτικούςοικισμούς.1β. Πεδινές περιοχές γραμμικής οικιστικής ανάπτυξης κατά μήκος τουθαλάσσιου μετώπου με διάσπαρτη, άναρχη δόμηση (νόμιμη ή μη) και μεχρήση παραθεριστικών κατοικιών και τουριστικών καταλυμάτων.
2. Περιοχές (σχετικώς επικλινείς).2α . Περιοχές επικλινείς με έντονο ανάγλυφο με βοσκότοπούς καιπαραδοσιακές καλλιέργειες, με ή χωρίς αναβαθμίδες και αγροτικούςοικισμούς.2β. Περιοχές επικλινείς με έντονο ανάγλυφο, γραμμικής οικιστικήςανάπτυξης κυρίως κατά μήκους του θαλάσσιου μετώπου με διάσπαρτη,άναρχη δόμηση (νόμιμη ή μη) και με χρήση παραθεριστικής κατοικίαςκαι τουριστικών καταλυμάτων.
3. Περιοχές ( με μεγάλες κλίσεις) με δασική ή μη βλάστηση ψηλή ήχαμηλή και έντονο ανάγλυφο – βραχώδεις ακτές, με χαμηλή

1. Flat Areas.1α. Plains (flat terrains) with intensive cultivations and rural settlements .
1β. Flat areas with linear urban development-especially along the sea front- having scatteredbuilding constructions (illegal or not). Dominant land uses: secondary residence and touristaccommodation
2. Rough terrains.2α . Rough terrains. Land cover: pastures, maquis vegetation, bush land, Traditional cultivations interraces, rural settlements2β. Rough areas with linear urban development-especially along the sea front- having scatteredbuilding constructions (illegal or not). Dominant land uses: secondary residence and touristaccommodation
3. Mountainous areas covered by forest vegetation or maquis, rough terrain, rocky coasts, lowpopulation density or empty.
