Description:

Abstract: This layer represents Substations. Substations are facilities and equipment that switch, transform, or regulate electric voltage. The Substations feature class includes taps, a location where power on a transmission line is tapped by another transmission line. **** Geographical coverage includes the Continental United States and a portion of British Columbia and Alberta.

Purpose: This feature class is for the Homeland Infrastructure Foundation Level Database (HIFLD) (https://gii.dhs.gov/HIFLD) as well as the Energy modelling and simulation community.

Supplemental Information: If you are using this dataset as a shapefile, please be aware that it was converted from a Geodatabase. As a result, this shapefile may have attribution and metadata errors resulting from the conversion process. The following are known issues: null values may have been changed to 0s (zeros) or to blank values, numbers (including latitude and longitude) may have been rounded up or down, there may be issues with Unicode character strings, and time cannot be stored in a date field. Field names may have been truncated to no longer than 10 characters or completely changed, lengthy string attributes may have been truncated to 254 characters, and attribute columns may have been deleted. Shapefiles do not support coded domains and subtypes therefore the original file geodatabase attribution and metadata information for coded domains and subtypes could be incorrect or missing in the shapefile version. Please visit the following ESRI website for more information: caution-http://pro.arcgis.com/en/pro-app/tool-reference/appendices/geoprocessing-considerations-for-Shapefile-output.htm

Data Quality Information:

Attribute Value Accuracy Information:

Attribute Accuracy Report: No formal attribute accuracy test was conducted. Data from the authoritative sources (as identified in other sections of this metadata) is assumed to be correct and accurate. See also “Overview Description” in the “Entities and Attributes” metadata section.

Logical Consistency Report: Data were extracted from sources (identified in the SOURCE field) and other open source websites to populate the attribute fields; NOT AVAILABLE values (for string and date data types) and Null values (for numeric data types) denote missing data that was not present in the source data. During quality control, attributes were checked to ensure that they fell within the expected ranges or had expected/valid values. Text attribute values were checked for spelling and usage consistency. No topology tests were conducted. All records were verified to occur within the spatial domain of the feature class.

Completeness Report: Data is complete given available sources.

Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report: None; all efforts are made to place the geographic representation of the facility on-entity using the best available imagery from a wide variety of sources. Users should read and understand the METHOD metadata as well as the Processing Steps.

Vertical Positional Accuracy:

Vertical Positional Accuracy Report: None; dataset contains no vertical data.

Process Step:

Process Description:

Authoritative data sources are identified through open source research. That data is then acquired and transformed into a usable data format. The properly formatted data then goes through preprocessing steps that includes a georeferencing or spatial adjustment operation to give spatial context to the data. In the absence of authoritative sources, feature geometry is created based on interpretation of the best available imagery. The data goes through further refinement using remote sensing techniques. After preprocessing, records go through a review process in an effort to meet the goal of placing each feature on a facility based on-entity location based on interpretation of the best available imagery and open source information. The DATE field indicates the date in which the review step took place.
