Introduction Environmental professionals collect, process and interpret massive amounts of environmental data.
Modern systems acquire data from a variety of sources, scales and resolution.
They store, retrieve and manipulate that data for analysis and modeling, and then generate outputs such as maps, cross sections, and tables. On-screen access to data enhances environmental project management by providing immediate feedback to decision makers. Laser binoculars provide bearing distance and elevation directly onto CAD based field maps without transciption errors. The users designs relational data bases and links them to graphic sym-bols on the map. He inputs or edits data through pop-up forms displayed on the screen.
