TOPOGRAPHIC MAPPING (SHP) - FEATURE ATTRIBUTE SUMMARY

 

 

1)

STREET CENTRELINE (singleStreetCentreline.shp)

 

Feature Type: Line

 

Attribute Field Name

Description

 

FID

Guaranteed unique feature Identification number (computer generated field)

 

Shape

Shapefile geometry type (Computer generated field)

 

FULLNAME

2)

2017 TOPO FEATURES (various shapefiles)

 

Feature Type: Varies

 

Each shapefile in the dataset contains a combination of the following attribute fields within their associated Feature Attribute Tables (FATs) as described below.

 

Attribute Field Name

Description

Applicable Shapefile GeometryType

Point

Line

Polygon

 

FID

Guaranteed unique feature Identification number (computer generated field)

 

Shape

Shapefile geometry type (computer generated field)

 

THEME

Thematic classification used for organizing the topo dataset

 

LAYER_NAME

Output CAD drawing layer name (used for exporting)

 

FEAT_CODE

The original Ontario Base Mapping feature codes used to distinguish groups of features

 

YEAR

The year in which a building was added or revised in the dataset

(Building Outline features only)

 

 

 

ELEVATION

Height above sea level measured in metres (3D features only)

 

 

ROTATION

Angle of rotation used to rotate point symbols about the insertion point

 

 

 

TEXT_ANGLE

Angle of rotation used to align with associated features

 

 

TEXT_SIZE

The size of text measured in ground units when displayed at a scale of 1:2,000

 

 

TEXTSTRING

The annotative text string used for labeling

 

 

LENGTH

The computer calculated linear length of features (metres)

 

 

AREA

The computer calculated enclosed area of polygon features (metres)

 

 

 

COORD_X

The computer calculated horizontal (northing) coordinate position value

 

 

 

COORD_Y

The computer calculated vertical (easting) coordinate position value

 

 

 

 

The Topo Feature Code Layer Reference database (MDB) database file contains a table which can be used to cross-reference shapefile names, layer names, feature codes, feature descriptions, and feature types for all topographic features.

 

All topographic features in the dataset are in 2D, except for the Relief data, which is represented in 3D.

 

The DEM files are provided in Bentley Microstation DGN (v7) format. Refer to the INDEX.pdf, which is located in the Topo (PDF) folder for further reference.
