Navigating INFO: Database Hygiene
(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
(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
(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, ...
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.
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 ...
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 ...
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 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 ...
From GIS to Geo-Informatics
(Missouri Spatial Data Information Service, 1999)
Geo-Informatics are the integration of: a)GIS - geographic information systems, b) Remote Sensing - satellite and aircraft, c)GPS - global positioning systems and d)Digital photogrammetry, all in the larger context of ...
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 ...
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 ...
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 ...
