Littosat is a comprehensive monitoring solution that that converts optical satellite imagery into actionable insights about coastal environments<\/span>. This data enables monitoring of, for example, intertidal vegetation, turbidity, shallow-water bathymetry, and algal bloom-related phenomena.<\/p>\n

More than just a visualization tool, Littosat is a comprehensive infrastructure that combines the collection, processing, analysis, visualization, and distribution of satellite data<\/span> tailored to business and operational needs.<\/p>\n

Thanks to reliable, certified satellite products<\/span>, automated API services <\/span>and GIS and web interfaces<\/span>, Littosat facilitates data access for public agencies as well as private entities such as consulting firms specializing in the environment or aquaculture.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n
