Remarks

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

Process for EGIS integration

WMS Web Service:

1. WMS Web Service can be integrated directly into EGIS.

SHP File:

1. SHP file can be integrated directly into EGIS.

2. Process ROADSEG dataset only.

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\NationalRoadNetwork\NationalRoadNetwork.kmz

Customization:

1. Schema transformation: As required

2. Denormalization: It is recommended to perform minimal generalization on 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 by ROADCLASS is recommended to improve visualization. Local/Street should display at larger scale.

7. Format translation: Not required

8. Language translation: French version available

9. Update frequency: As identified
