Sampling the World
(Missouri Spatial Data Information Service, 1999)
as complete and accurate a view of the world as possible. The contents of the database must be relevant in terms of: a)themes and characteristics, b)the time period covered, and c)the study area. This presentation looks at techniques for sampling the world...
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 benefits, transition...
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 to test product quality...
GIS Introduction & Overview
(Missouri Spatial Data Information Service, 1999)
GIS is the primary driver for its very own, ever greater, acceptability and use. Everyone likes maps and graphics and the computer makes it easier for you to visualize your data. GIS growth feeds on its own successes and builds new and more complex...
Spatial Interpolation
(Missouri Spatial Data Information Service, 1999)
Spatial interpolation is the procedure of estimating the value of properties at unsampled sites within the area covered by existing observations. In almost all cases the property must be interval or ratio
scaled. It can ...
Data Source Evaluation
(Missouri Spatial Data Information Service, 1999)
This presentation looks at different types of socio-economic data, including disaggregated Data (data about individuals or single entities) and aggregated data (data consisting of a group of observations with the grouping made on a defined criterion...
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 system? What...
From GIS to Geo-Informatics
(Missouri Spatial Data Information Service, 1999)
) and computer systems. This presentation discusses technological and organizational reasons to use Geo-Informatics, as well as some of the thousands of applications for this technology. It goes on to look at some strategies for storing data in a Geo...
Missouri GAP Analysis
(Missouri Spatial Data Information Service, 1999)
Presentation focusing on integrating GIS & related technologies into natural resource planning & management. It touches on angles such as sensitivity analysis, cartographic considerations, biodiversity assessment, and strengths and weaknesses...
Coordinate Systems
(Missouri Spatial Data Information Service, 1999)
This presentation offers an introduction to coordinate systems. Coordinates are used to identify locations on the earth's surface and are based on measurements of displacement from a given location. The number of significant digits required for a...
Navigating INFO: Using INFO with AML
(Missouri Spatial Data Information Service, 1999)
as blank lines. AML uses REM inside INFO data blocks, and document lines intentionally left blank...
Functional Requirement Study
(Missouri Spatial Data Information Service, 1999)
This presentation looks at Functional Requirement Studies (FRS) for GIS. A FRS consists of five steps: 1)Identify Decisions, 2)Determine Information Products Needed, 3)Determine Frequencies, 4)Identify Data Sets Required, and 5)Determine GIS...
Affine & Curvilinear Transformations
(Missouri Spatial Data Information Service, 1999)
Coordinate transformations are required when
you need to register different sets of coordinates for objects in the same area that may have come from maps of different (and sometimes unknown) projections. There are two ...
Database Concepts
(Missouri Spatial Data Information Service, 1999)
This presentations highlights the advantages of using a database management systems approach to GIS. Database usage will lead to a reduction in data redundancy, as shared rather than independent databases will reduce the problem of inconsistencies...
GIS Tools
(Missouri Spatial Data Information Service, 1999)
This presentation offers a discussion of tools for use in GIS. It begins with a list of GIS software components, including graphics processing, database management, basic cartographic functions, special applications, and application development...
Database Design
(Missouri Spatial Data Information Service, 1999)
This presentation focuses on the design of GIS databases, starting with topographical structure. Database design is a scheme in which database goals are defined and database alternatives are laid out, analyzed, and an alternative is selected...
Missouri GAP
(Missouri Spatial Data Information Service, 1999)
This presentation offers a geographic approach to planning for biological diversity. It is focused on building a database for GAP analysis in Missouri, looking at land cover types, data layer tracking and distributions of specific animals....
Temporal & 3-D Representations
(Missouri Spatial Data Information Service, 1999)
Although the vast majority of GISs currently
work only in two dimensions, across the plane, certain applications require the addition of other dimensions, namely time or elevation/depth. Most geological applications require ...
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 ...
Database Concepts
(Missouri Spatial Data Information Service, 1999)
. Certain types of DBMS are more suitable for GIS than others because their assumptions fit spatial data better....
