Description

An Abandoned Railway is a railway line which is no longer used for that purpose. Such lines may be disused railways, closed railways, former railway lines, even derelict railway lines. Some have had all their track and sleepers removed, and others have material remaining from the former use.

Remarks

  1. The most appropriate dataset to use for EGIS would be from WMS web service as it does not require periodic updates.

  2. Abandoned Railway is a subset of National Railway Network where the status of the track is either discontinued or unknown.

  3. Josh looked at adding this as a filtered WMS and didn't get very far. In reaching out the contact address of the WMS it was suggested that we consider rail data from CanVec available on Canada Open Data

Process for EGIS integration

WMS Service:

  1. This web service can be integrated directly into EGIS. Simply filter on Status=Discontinued or Unknown

SHP File

  1. SHP file can be integrated directed into EGIS. Simply filter on Status=Discontinued or Unknown

TC Smart Maps:

  1. Not all GIS applications can consume KML file directly due to its unique data structures such as networklinks, folders, models etc.

  2. Please contact Lawrence Chong, Digital Services Directorate for TC Smart Maps KML dataset and format translation.

  3. TC Smart Maps KML link: \\tc.gc.ca\tcgis\GISData\Google Mashup\Surface Engineering-Rail Data\RailAbandoned\RailAbandoned.kmz

Customization:

  1. Schema transformation: As required

  2. Denormalization: It is recommended to perform minimal generalization on NRWN tracks, yards and spurs to improve display performance.

  3. Value coding: Not required

  4. Attribute renaming: As required to improve readability

  5. Attribute removal: It is highly recommended as some fields are unnecessary, this will also reduce file size and improve performance

  6. Geoenrichment: Feature symbolization is recommended to improve visualization

  7. Format translation: As needed

  8. Language translation: French version available for NRWN.
