Navigating INFO: Using INFO with AML
(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: Additional Concepts
(Missouri Spatial Data Information Service, 1999)
This presentation looks at some aspects of INFO not covered by previous presentations. They include creating and using arrays, cross-tabulation, redefined keys, alternate directories, displaying text with INFO, purging ...
Navigating INFO: Advanced Processing
(Missouri Spatial Data Information Service, 1999)
This presentation deals with data structures and algorithms not inherent to ARC. It is mostly concerned with line coverages (AATs). Topics include: node-arc lists (NAL), NODE Valence tables (VAL), dangling and orphan ARCs, ...
Navigating INFO: Programming
(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.
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 ...
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 ...
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 ...
Designing Better Maps
(Missouri Spatial Data Information Service, 1999)
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; ...
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 ...
CAD versus GIS: Which is better for Automated Mapping?
(Missouri Spatial Data Information Service, 1999)
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 ...
Accuracy and Visualization
(Missouri Spatial Data Information Service, 1999)
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 ...
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 ...
GAP
(Missouri Spatial Data Information Service, 1999)
Slideshow from a presentation containing schematic diagrams showing steps in the development of a generalized predicted vertebrate, amphibian, reptile, bird, or mammal distribution map for Gap Analysis.
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
