MARPLOT® is the mapping program for the CAMEO® software suite, which is used widely to plan for and respond to chemical emergencies.
MARPLOT’s easy-to-use GIS interface allows you to add objects to a map, as well as view and edit data associated with the objects. You can choose between several background basemap images, and you can customize your map further with annotations and online layers from Web Mapping Services. You can also interact with the map in other ways, such as getting population estimates within an area. MARPLOT can be run by itself as a general mapping program. It can also be used interactively with programs in the CAMEO suite to display ALOHA® threat zone estimates on the map or to link map objects to database records in CAMEO Data Manager.

If you already have an older version of MARPLOT: Before installing the new MARPLOT, make a copy of your current MARPLOT Data folder and save it to a backup location. For Windows users, if you install the new MARPLOT version in the same location as your old MARPLOT 5.1 or 5.0.x version, MARPLOT will upgrade to the latest version while also keeping your current data and settings. For Mac users, there is an extra step required in the installation process. Follow the on-screen instructions in the DMG installer to upgrade your data. Note that if you're upgrading from a MARPLOT 4 series version, you need to follow additional instructions before installing the latest MARPLOT 5 version.
