  • Navigating INFO: Using INFO with AML 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    AML is a type of variable substitution, with AML variables set as arguments or by directives. A stored value is substituted for variable name. Variable values are substituted and embedded into the INFO program code. Variables ...
  • Navigating INFO: Programming 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation looks at various programming aspects of INFO, including odd and even program sections, compiling and decoding, debugging techniques, editing, running programs with LINK, and menu files and programs.
  • Navigating INFO: Database Hygiene 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    Database hygiene is the process of creating and maintaining an efficient relational database, as well as modifying existing databases that were poorly defined or implemented. Subtopics offered in this presentation include ...
  • Navigating INFO: Relates 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    INFO database diagrams are graphics showing all the info files in a relate sequence. This presentation offers several, including the General Relate, the Ordered Relate, the Link Relate, the Double Relates, the Append Relate, ...
  • Navigating INFO: Introduction and Key Concepts 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation looks at the basic of using INFO. INFO is the language of choice for many GIS Algorithms. It is the most accessible programming language in ARC/INFO, as AML cannot access all data and records in a coverage, ...
  • State Bodies 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation looks at the state bodies which oversee GIS. It includes lists of their most important missions regarding GIS, the reasons the state bodies were created, their most important success factors, and their ...
  • Data Discovery and the NSDI Framework Data Survey 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation provides background on the use of FGDC-style metadata for Clearinghouse Development, and provides managers and users with guidance on the use of the Clearinghouse to find spatial data. A Clearinghouse ...
  • The NSDI Framework Data Survey 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    The NSDI Framework is the data backbone for the NSDI, providing data, procedures, and technlogy. It is a way to facilitate 1)the production of geographic data, 2)the use of geographic data, 3)the reduction of operating ...
  • MSDIS (No Graphics) 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation provides (with fewer graphics than the similarly-named file) an introduction to the Missouri Spatial Data Information Service. It is a spatial and tabular data retrieval and archival system. MSDIS is ...
  • MSDIS 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation provides an introduction to the Missouri Spatial Data Information Service. It is a spatial and tabular data retrieval and archival system. MSDIS is responsible for data storage and access, standardization ...
  • Metadata Standards Status & Futures 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation looks at the Federal Geographic Data Committee's Content Standard for Digital Geospatial Metadata Version 2 (CSDGM), which is an update from from the previous version and was approved in 1998. It also ...
  • Discovering Spatial Data: Use of the Clearinghouse 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation provides background on the use of FGDC-style metadata for Clearinghouse Development, and provides managers and users with guidance on the use of the Clearinghouse to find spatial data. A Clearinghouse ...
  • Developing National Geospatial Data Standards 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation looks at a proposal for the formation of national standards for Geospatial data. It looks at duties and subcommittees of the Federal Geographic Data Committee, with specific focus on the Standards Working ...
  • Vector GIS 

    (Missouri Spatial Data Information Service, 1999)
    The Vector GIS model is based on vectors (as opposed to spaceoccupancy raster structures). Its fundamental primitive is a point. Objects are created by connecting points with straight lines. Some systems allow points to ...
  • Spatial Databases as Models of Reality 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    The real world is too complex for our immediate and direct understanding. We create “models” of reality that are intended to have some similarity with selected aspects of the real world. Databases are created from these ...
  • The Raster GIS 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    Current GISs differ according to the way they organize reality through the data model. Each model tends to fit certain types of data and applications better than others. The data model chosen for a particular project or ...
  • GIS Tools 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation offers a rundown of tools for use in GIS. GIS application software components include graphics processing, database management, basic cartographic functions, special applications, and application development ...
  • GIS Planning and Management 

    Haithcoat, Tim (Missouri Spatial Data Information Service, 1999)
    This presentation offers tips on planning and management of a GIS. To be functional, a project database should contain coverages that have the following characteristics: 1)Each coverage contains clean topology, 2) The ...
