AQUARIUS Summary Specification Sheet The ALTM Aquarius is an innovative compact solution for mapping coastal and inland waterways. Compatible with the ALTM Gemini system, Aquarius collects simultaneous land and water-depth measurements, enabling wholly complete data sets that span the land/water interface. Designed as a complementary sensor to Optech’s fullfeatured lidar bathymetry systems, Aquarius provides depth information in relatively shallow water environments not previously accessible to conventional topographic mapping sensors alone.
