redundancy
[ESRI software] In Survey Analyst, occurs when the number of observed measurements is greater than the number of computed coordinates in a measurement network.
The product range (ptf 1206A, ptf 1207A, ptf 1220, and ptf 1226) includes multiple combinations and options for redundancy applications, enabling a company to develop architectures appropriate for almost any system requirement needing RF, ...
REDUNDANCY
B-13. Redundancy in the observations is the best way of dealing with most of the error sources. Specific observing procedures and differencing techniques can eliminate other error sources that are more systematic.
Redundancy in coverage is a measure of protection from localized catastrophe. As redundancy in coverage increases from 1 to 5 separate parcels of land, the percent of species not covered increases for all taxa.
Reduce time and redundancy of data production by connecting geospatial data and service producers with consumers.
Maintain data integrity by allowing organizations to easily share the authoritative version of data among its users.
Because of natural redundancy (e.g. the same object for different scales has different geometrical representation but unchanged attributes, or the same object for different time periods has different attributes but the same geometrical representation, ...

A typical goal in relational database design is use many-to-one relates to reduce data storage and redundancy.
The result of this process was that there were multiple copies of data on local machines, with the risk of redundancy and low integrity, due to changing values on the main database.
Some of the potential benefits that an enterprise GIS can provide include significantly reduced redundancy of data across the system, improved accuracy and integrity of geographic information, and more efficient use and sharing of data (Sipes, 2005).
Users can visualize the fiber or optical system path on a map, review distance and budget loss, and use the model in strengthening the network with fiber redundancy.
Geographically enable your IT investments, shrinking data and application redundancy, optimizing system configurations and consolidating enterprise systems ...
As communication increases among individuals and departments, redundancy is reduced, productivity is enhanced, and overall organizational efficiency is improved.
Circuit A description of a network with one or more loops [creating alternative paths between nodes and thereby network redundancy] ...
Future aircraft will use L5 in combination with L1 C/A to improve accuracy (via ionospheric correction) and robustness (via signal redundancy).
In the future, the company plans to integrate its facilities and technical data into the GIS system to bring more information into a common, georeferenced database, which will minimize redundancy and further expand the system's capabilities.
normalization A conceptual database design task that involves applying data dependency to a data model to avoid data inconsistencies by prohibiting redundancy.
many-to-one-relate : A relate in which many records in one table are related to a single record in another table. A goal in relational database design is to use one to many relates to reduce data storage and redundancy.
If many of the objects on the database have the same attributes they must be entered many times, leading to data redundancy and often to empty fields (resulting in wasted computer resources). A common example is the card index.
Many-To-One Relate A relate in which many records can be related to a single record. A typical goal in relational database design is use many-to-one relates to reduce data storage and redundancy.
This function is often required when data has been captured with too many vertices for the linear features. This can result in redundant data and large data volumes. The weeding of coordinates is required to reduce this redundancy.
Superior performance in foliated conditions
Metre level positioning accuracy
Resulting positions referenced to the NAD83 standard
24x7 operations with built in network redundancy
Open published broadcast protocol
No service costs ...
This not only reduces redundancy; it also allows for more accurate data and a greater understanding of how the same data is used by multiple departments.
The very real needs to minimize data redundancy and establish data consistency are the driving forces behind OODBM. Its application to GIS is simply one potential expression of the looming radical changes in data base technology.
