What is the .NTF File Extension?

.NTF File Extension Description:

The NTF file extension identifies map files used by the Ordinance Survey, the national mapping agency of Great Britain. It provides the most accurate geographic data to the government, individuals, and businesses. These files are based on the National Transfer Format specification of the British Standards Institution designed specifically for the transfer of spatial information.

Files with the .ntf file extension are represented as having two segments where each contains the same vectors but with different attributes. The first segment contains vectors with the feature code as the attribute whereas the second segment contains vectors with the value as the attribute.

The DATASET directory contains one or more files with the .ntf file extension. Each file in the directory has an ID used to specify the number of available file with the .ntf file extension that can be read. If no ID is specified, then all available files with the .ntf file extension are already read.

The file with the .ntf file extension can contain the keyword FORCE_GENERIC. This keyword is utilized to distinguish products to be treated making use of the generic rules instead of the rules that are product-specific. This could be helpful if new versions of the standard products are improperly treated by product-specific rules or if you want that all features from different products returned using a common or generic schema.

The keyword DEM_SAMPLE can also be found in files with the .ntf file extension to specify a decimation factor that is applied in the horizontal and vertical directions. A value of 3, for example, can return only one of the three points in both horizontal and vertical directions from the reader which results in 8/9ths reduction in the total number of features.

Features read from files with the .ntf file extension consist of their geometry and a series of attribute values. Several features like the FEATURE_CLASSES contain no geometry and are established by the classification of record that these files have as well as the features of this special product are extracted.
