Product Change Details¶

Note

The information below is current at the time this report was published. There is a possibility the final release may contain additional changes. These will be described in the associated release report.

Buildings¶

New roof_slope attribute¶

A new roof slope attribute will be added to the Buildings product. This attribute (roof_slope) will represent the maximum slope angle for a roof in degrees. The roof slope will be classified in ranges, described in the table below. The data type will be number (4,2), with the ESRI Shapefile 10 character alias being ROOF_SLOPE.

The roof slope attribute will be provided for buildings captured from aerial imagery, all other records will have a <NULL> value.

The addition of this new attribute will result in a minor increment to the Buildings product version, making it 3.2.

Domain Values¶
Domain Value	Description
0	The angle of the building roof is greater than or equal to 0 degrees and less than 14.04 degrees. The building has a flat roof.
14.04	The angle of the building roof is greater than or equal to 14.04 and less than 22.62 degrees.
22.62	The angle of the building roof is greater than or equal to 22.62 and less than 30.26 degrees.

42.51	The angle of the building roof is greater than or equal to 42.51 degrees.
<NULL>	The building has not been assessed for roof slope.

File Geodatabase (GDB) format - Removal of relationship classes¶

The File Geodatabase format will no longer support relationship classes between records included in the layers within the GDB. This does not mean any change to the representation of the layers within the file.
