PACKAGE INCLUDES
—————————————————————————————————–

1. LICENSE_MetropAccess-Digiroad.txt – Includes metadata and license information.

Modified MetropAccess-files:
…………………………………………………….

1. METROPACCESS-DIGIROAD_LIIKENNE_ELEMENTTI.shp is a street network that can be used for route optimization and network analyses in all GIS softwares that support network analysis (e.g. ArcGIS, QuantumGIS, GRASS).

2. METROPACCESS-DIGIROAD_LIIKENNE_ELEMENTTI_ND.nd is a specific ArcGIS network dataset (.nd) that is instantly ready for analysis (only) in ArcGIS 10.0, 10.1, and possibly in 10.2 (not tested). Doing analysis requires Network Analyst -extension.

3. METROPACCESS_DIGIROAD_LIIKENNE_ELEMENTTI_ND_Junctions.shp – Node point dataset that is required in ArcGIS Network Dataset (.nd).

Additionally the package includes information about different street network elements in LiikenneElementit folder:

4. Liikennevalot.shp are intersections that are associated with traffic lights.

5. KevytLiikenne.shp are intersections that are associated with pedestrian and cycle routes.

6. Rampit.shp are intersections that are associated with ramps.

7. TavallisetRisteykset.shp are intersections that are NOT associated with any of the earlier street network elements.
