Alleco also conducts mapping of bottoms by using normal, as well as side scan sonar. Our equipment includes both fixed, as well as movable side scan sonars and single beam depth sonars. Our equipment is best suited for mapping and photograping of bottoms in fairly shallow areas, between 0-20 m. As a result of our compact and movable equipment we can also map small and remote waters. We map biological-, geological- as well as archeological sites efficiently and with a high degree of precision. When combined with biological and geological sampling, we produce habitat and biotope maps with the modern spatial modelling techniques.
