24 24 Tribal Case Study: Modeling Mobile 5a & 5b DOS system FORTRAN No GUI Not as easy to use

25 25 Tribal Case Study: Modeling Computer Aided Management of Emergency Operations (CAMEO) Areal Locations of Hazardous Atmospheres (ALOHA) Mapping Applications for Response, Planning, and Local Operational Tasks (MARPLOT)

26 26 Tribal Case Study: Modeling CAMEO Chemical search engine Linked to chemical-specific information firefighting techniques, cleanup procedures, and protective clothing Basic information on Tier II facilities that store chemicals Emergency planning resources

27 27 Tribal Case Study: Modeling ALOHA atmospheric dispersion model used for evaluating releases of hazardous chemical vapors

28 28 Tribal Case Study: Modeling MARPLOT allows users to "see" their data (e.g., roads, facilities, schools, response assets) Display this information on computer maps Overlay areas contaminated by potential or actual chemical release Maps created from the U.S. Bureau of Census TIGER/Line files

29 29 Tribal Case Study: Modeling CAUTION Before installing software Check with LAN administrator or your Techie Review operating system requirements

30 30 Tribal Case Study: Modeling Before you start README files Manuals Instructions First things first!

31 31 Tribal Case Study: Modeling DOS-based systems E.g. FORTRAN Require INPUT files Data entry very specific in format and placement Uses abbreviations Truncation
