In LandView, clicking on the Go To Map button opens the MARPLOT application. Each record in a LandView database represents the informational attributes associated with a geographic entity in MARPLOT. Selecting one record or multiple records in LandView allows display of the associated map objects in MARPLOT. These can be viewed either as independent entities or in relation to other map objects or to topological data such as roads or rivers. Conversely, identifying one or more map objects in MARPLOT allows for the display of the associated informational attributes in LandView.You can go to the MARPLOT program from LandView by clicking on the Go To Map button; you can return to LandView by clicking Sharing/LandView/Go to LandView in the Menu Bar. Alternatively, you can switch between programs by clicking on the MARPLOT and LandView tabs in the PC Windows task bar. MARPLOT has its own set of help screens. To obtain detailed instructions on using MARPLOT, choose Help from the menu bar in the MARPLOT application, or reference the MARPLOT User's Guide and MARPLOT Getting Started. Advanced users of MARPLOT might take a look at the MARPLOT Technical Documentation [PDF]. Lastly, EPA sponsors a LandView, MARPLOT and CAMEO discussion forum for those users that are interested. The LandView 5 product contains the 3.3 version of MARPLOT software. CAMEO is a system of software applications used widely to plan for and respond to chemical emergencies. It is one of the tools developed by EPA’s Chemical Emergency Preparedness and Prevention Office (CEPPO) and the NOAA Office of Response and Restoration to assist front-line chemical emergency planners and responders. They can use CAMEO to access, store, and evaluate information critical for developing emergency plans. In addition, CAMEO supports regulatory compliance by helping users meet the chemical inventory reporting requirements of the Emergency Planning and Community Right-to-Know Act (EPCRA, also known as SARA Title III). CAMEO also can be used with LandView to display EPA environmental databases and demographic/economic information to support analysis of environmental justice issues. Additional on CAMEO is available from the CAMEO Web site.
The ALOHA air dispersion model predicts the downwind dispersion of a hazardous chemical cloud. Graphical outputs include estimates of the cloud footprint (representing the area where hazardous gas concentrations may reach a level of concern), the rate and duration of release of the chemical to the atmosphere, and chemical concentration over time at locations of particular concern. Additional information on ALOHA can be found on the ALOHA Web site.
