GeoData Sentry Version 3.4 Technical Specifications

What's new in 3.4

Integration with GeoData Random Sampler

GeoData Sentry 3.4 allows users to write the errors to GeoData Random Sampler format. Now when errors are detected with Sentry, they can be viewed with Random Sampler. If you are not familiar with Random Sampler, it is an ArcMap extension for sampling features, inspecting and correcting errors. Sentry now leverages Sampler’s ability to zoom to errors. Errors may be noted for correction, or they can be corrected on the spot using GeoData Random Sampler.

 

Command Line Execution of GeoData Sentry

GeoData Sentry 3.4 includes the ability to run at the command line. This allows users to create batch files to be run as scheduled tasks. This function gives Sentry the flexibility to run on-demand via the user interface, or on a specific schedule, via the scheduled task. Scheduled validation with Sentry maintains geodatabase data quality well beyond the data acceptance phase in a geodatabase lifecycle.

 

Minimum Requirements

  • ArcGIS 9.3.1 or higher
  • ArcView license or higher
  • Microsoft .NET Framework Version 2.0 Redistributable Package (x86)

Test Inventory

Single Column Attribute Tests
Unique Values Detects non-unique values for a column. Useful for columns that are being used as primary keys or columns that represent feature identifiers where uniqueness is required.
Coded Domains Detects non-legal values based on pre-established geodatabase Coded Domains, existing DBMS tables or a user-defined list of valid values. All values for a tested column must contain only legal values
Coded Ranges

Detects out of range values based on pre-established geodatabase Range Domains or user-defined minimums and maximums. All values for a tested column must contain only legal values.
Single Values Detects values other than the specified single value for a column. All values for a column must equal the specified value.
NULL Values Detects NULL, blank and/or zero values for a column. Can detect NULL occurrences if NOT NULL constraints are disabled while loading the data into the geodatabase. Also detects blank and/or zero values occurring in legacy INFO tables.
Non-Standard Values Detects non-standard keyboard values such as !@# and ? in a column. A list of these values may be configured for each column.
Column Length Detects values that are not the specified length

Multiple Column Attribute Tests
Custom Query Reports results of a user defined query to the database. These queries are in the form of a where clause, much like select by attributes in ArcMap.

Referential Integrity Tests
Table Relationship
Detects unmatched relationship keys between two tables in a join. No orphan table rows are allowed.

Spatial Relationship Tests
Intersect The Intersect test detects features from one feature class that do not intersect with features from a second feature class. This test is critical to detecting spatial problems between feature classes. The quality of the geometric network may be compromised if features that are supposed to participate in the network are not coincident with the network. These errors can be detected prior to building the network. Data that has been loaded into the geodatabase from another GIS system may not be snapped to the required level of the geodatabase, in order to build a correct geometric network.

Logical Connectivity Tests
Junction To Edge Test The Junction to Edge Test detects where a junction is connected to an edge where it should not be, based on either the connectivity rules from the geometric network, or user defined rules, such as phase mismatch between device junctions and connected conductors, or diameter mismatch between valves and pipes.
Edge To Edge with Junction Filter Test The Edge to Edge with Junction Filter Test detects where two edges are connected at a junction where they should not be, based on either the connectivity rules from the geometric network, or user defined rules, such as different pipe sizes connected a junctions that are not reducing junctions, or differential phased edges connected at open switches
Edge To Edge Test The Edge to Edge Test detects where two edges are connected that should not be, based on either the connectivity rules from the geometric network, or user defined rules, such as line size, voltage, diameter, phase designation or material.

 

Sentry Editions

GeoData Sentry has three different Editions with various test availability and geodatabase support, Personal, Professional and Enterprise Edition.

The Personal Edition allows for connections to personal geodatabases with attribute testing.

The Professional Edition allows for connection to personal, file and SDE geodatabases with all testing except for logical connectivity.

The Enterprise Edition allows for connection to personal, file and SDE geodatabases with all testing included.

For more details see Sentry Editions.

Licensing and Maintenance

GeoData Sentry™ is node locked to the computer that is is loaded onto. Once Sentry is installed you must contact Laurel Hill for a keycode to enable the software. There is an annual maintenance fee per license, depending on the licensed edition, for software upgrades, bug fixes and technical support. The first year of maintenance is complimentary.
