GAIT (Defense Mapping)
Summary
The Geospatial Analysis Integrity Tool (GAIT) validates data against a data model. GAIT checks geometry, feature codes, attribute values and domains, and metadata. The tool writes its results as line and point shapefiles to an output directory. GAIT can execute against data in MGCP, GIFD, TDS, and VMap data models.
Usage
You must have CYGWIN and GAIT 1.7 installed to use this tool.
-
The attribution schema must match the schema of the input feature layer.
The inspection profile represents a set of checks to run during GAIT and depends upon the data model set in the Attribution Schema parameter. Use the tool dialog box or the Python window to see valid domain values.
The values of the Metadata Mapping Table parameter depend upon the attribution schema. Use the tool dialog box or the Python window to see valid domain values.
Syntax
| Parameter | Explanation | Data Type |
in_features |
The features to validate. | Feature Layer;Table View |
gait_exe |
The path to the GAIT executable file. | File |
folder |
The shapefile export directory. | Folder |
schema |
The data model that corresponds with the data displayed in input feature layer. | String |
project |
The name of the project. The project contains validation information, such as the checks run on the data and the results. | String |
format |
The set of checks to run on the data. This is specific to the data model listed in the attribution schema. | String |
metadata |
The metadata mapping table that corresponds to the data model of the input feature layer and the attribution schema. | String |
silent | Indicates the amount of output messages to return from GAIT.exe.
| Boolean |
reviewer_workspace (Optional) |
The workspace to which to write output features. Each shapefile result record is written to the reviewer table in this workspace. | Workspace |
specfile (Optional) |
A file that defines custom checks. | File |
Code Sample
This stand-alone Python script demonstrates running GAIT against MGCP data.
