WinATLAS is our standard tool for digitizing and editing map data. It forms the basis for our softcopy stereoplotter WinATLAS/DSP, and it supports online input from most analog and analytical stereoplotters, as well as a variety of digitizing tablets. The program provides multiple ways to access the different collection modes and editors. This makes it straightforward and intuitive for new users, and fast for experienced users. It was designed as a double precision 3D tool for the making of maps. It works in UTM, State Plane or assumed coordinates, and with either English or Metric units. It is constantly evolving to take advantage of innovations in computer and imaging technology, as well as adding features needed by our clients to meet the needs of their clients. And yet with all the evolution of technology you can stilll load and update files that were archived thirty years ago as if they were just saved yesterday.
