Processes NAVTEQ Streets data from NAVTEQ geodatabases to optionally produced the three road feature classes used in the EnviroAtlas community-based metrics:
- Walkable Roads
- Roads for Intersection Density Analysis
- Busy Roads - Interstates, Arterials, and Connectors
Walkable Roads:
- Process Navteq.gdb\Streets
- select features where FUNC_CLASS <> 1 or 2
- remove from the selection features where FERRY_TYPE <> H
- remove from the selection features where SPEED_CAT = 1, 2, or 3
- remove from the selection features where AR_PEDEST = N
- copy remaining selected features to [prefix]_RdsWalkable
Roads for Intersection Density:
- Process Navteq.gdb\Streets
- select features where FUNC_CLASS <> 1 or 2
- remove from the selection features where FERRY_TYPE <> H
- remove from the selection features where SPEED_CAT = 1, 2, or 3
- remove from the selection features where AR_PEDEST = N
- remove from the selection features where SPEED_CAT = 8
- assign Navteq.gdb\landUseA codes to road segments
- assign Navteq.gdb\landUseB codes to road segments
- trim unnecessary fields
- remove roads with no street names from these land use type areas: AIRPORT, AMUSEMENT PARK, BEACH, CEMETERY, HOSPITAL, INDUSTRIAL COMPLEX, MILITARY BASE, RAILYARD, SHOPPING CENTRE, or GOLF COURSE
- add a MergeClass field
- set MergeClass field value to an initial value of 1
- replace MergeClass field value to 0 where DIR_TRAVEL = 'B'
- convert any multipart roads to singlepart
- merge divided roads to [prefix]_RdsIntDens using the MergeClass field and a merge distance of '30 Meters'
- NOTE: Only roads with the same value in the mergeField and within the mergeDistance will be merged. Roads with a MergeClass value equal to zero are locked and will not be merged. All non-merged roads are retained.
Interstates, Arterials, and Connectors
- Process Navteq.gdb\Streets
- select features where FUNC_CLASS = 1, 2, 3, or 4
- remove from the selection features where FERRY_TYPE <> H
- copy remaining selected features to [prefix]_RdsIAC
- add field, LANES, to [prefix]_RdsIAC. Calculating its value as TO_LANES + FROM_LANES
- replace LANES field value to 2 for features where LANES field = 0
- NOTE: The user can locate and change these records with the following query: TO_LANES = 0 And FROM_LANES = 0
PNFEA (NAVTEQ_geodatabase, {Walkable_roads}, {Intersection_density_roads}, {Interstates,_arterials,_and_collectors}, Output_workspace, File_base_name)
Parameter | Explanation | Data Type |
---|---|---|
NAVTEQ_geodatabase | The path to the geodatabase. | Workspace |
Walkable_roads (Optional) | Specifies whether the Walkable Roads feature class will be generated.
|
Boolean |
Intersection_density_roads (Optional) | Specifies whether the Intersection Density Roads feature class will be generated.
|
Boolean |
Interstates,_arterials,_and_collectors (Optional) | Specifies whether the Interstate, Arterial, and Collector Roads feature class will be generated.
|
Boolean |
Output_workspace | The path to the Output workspace. If the Output workspace is a file folder, new layers will be saved as shapefiles. If the Output workspace is a geodatabase, new layers will be saved as geodatabase feature classes. |
Workspace |
File_base_name | A character string used as the file name prefix for all output feature classes. | String |
