The Raster GIS
(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
(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 ...
MSDIS
(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 ...
MSDIS (No Graphics)
(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 ...
Spatial Databases as Models of Reality
(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 ...
Discovering Spatial Data: Use of the Clearinghouse
(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 ...
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 ...
Metadata Standards Status & Futures
(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 ...
Developing National Geospatial Data Standards
(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 ...
Relational Database Management Systems, Database Design, and GIS
(Missouri Spatial Data Information Service, 1999)
This presentation offers an overview of several different ways to organize and present GIS databases. It begins with a comparison of hybrid models and spatial database servers. That is followed by advantages and disadvantages ...
GIS Planning and Management
(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 ...
Database Concepts
(Missouri Spatial Data Information Service, 1999)
Very early attempts to build GIS began from scratch, using limited tools like operating systems & compiler. More recently, GIS have been built around existing database management systems (DBMS). Purchase or lease of the ...
Implementation Planning
(Missouri Spatial Data Information Service, 1999)
This presentation addresses key questions involved in the implementation of GISs, including: What is included in a strategic plan? Is the scale of this GIS departmental or enterprise-wide? Is this a centralized or distributed ...
Database Design
(Missouri Spatial Data Information Service, 1999)
Database design is a scheme in which database goals are defined and database alternatives are laid out, analyzed, and an
alternative is selected or recommended. It implies that goals are identified and set, and a structured ...
GIS Personnel Issues
(Missouri Spatial Data Information Service, 1999)
This presentation runs through the people needed for creation and maintenance of a GIS. It includes positions, salary and compensation. The middle section looks at the impact that the GIS will have on those people, including ...
QA/QC and Risk Management
(Missouri Spatial Data Information Service, 1999)
This presentation looks at issues dealing with QA (Quality Assurance) and QC (Quality Control) in GISs. QA refers to to a comprehensive approach or system for ensuring product quality. QC refers to an action or step designed ...
Request for Proposal
(Missouri Spatial Data Information Service, 1999)
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 ...
Pilot Project Importance
(Missouri Spatial Data Information Service, 1999)
This presentation discusses pilot projects for GIS. Pilot projects merge the planning stages and implementation stages of project
development. They serve as a way to 'educate' management and build support for a project. ...
Data Discovery and the NSDI Framework Data Survey
(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
(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 ...
