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 costs, 4)improved service...

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 ...

-scale model of a future system). The presentation goes on to discuss management and results of the pilot project....

A need exists to have tools to transform spatial data of various types into digital format. Data input is a major bottleneck in application of GIS technology. The costs of input often consume 80% or more of project cost. ...

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 node minimizes duplication...

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 Group. It also includes...

step in coming to know the nature and status of that reality. A Spatial Database is a collection of spatially referenced data that acts as a model of reality. A database is a model of reality in the sense that the database represents a selected set...

This presentation discusses the basics of creating a Request for Proposal (RFP) for a GIS. It begins by discussing the advantages of an RFP, and continues onto contents and detailed specifications, as well as what to expect from vendors. Finally...

This presentation introduces the parts and pieces of a GIS, explains the components of a GIS system, review computer networks, examines peripherals, and explores what the future holds for GIS. It also discusses the role people play in the creation...

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 most important hindering...

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 ...

This presentation looks at the difference between Computerized Aided Drafting (CAD) and Geographic Information Systems (GIS) technologies, and how they can work together within the same organization. CID systems automate ...

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....

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 looks ahead to metadata...

This presentation offers an overview of GIS database creation, focusing on reducing errors and visualizing data rather than stating it. It includes a list of common errors - overlay errors and transitional errors get the most attention - as well...

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 of both digital...

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 responsible for data storage...

The theory of the visual display of quantitative information consists of principles that generate design options and that guide choices among options. The principles should not be applied rigidly or in a peevish spirit; they are not logically...

The Vector Data Model of GIS is based on vectors (as opposed to space occupancy raster structures). Its fundamental primitive is a point. Objects are created by connecting points with straight lines. Some systems allow points to be connected using...
