WebMap Route Service - Cannot create Graph file

Hi team

 

I am trying to set up a GeoMedia Route Service.

According to the on-line documentation one of the data requirements was to create a Graph file that can be used by the service, 

can find the on-line documentation here:

https://hexagongeospatial.fluidtopics.net/reader/jFUgMwV8rLquX7vj86E_6A/rY2yaY6_rFb_UTOJsYIbVA

 

10. Create Graph File

Data Format

Operation

Linear features

/CreateGraph

GM Network data

/CreateGraph

Transportation Manager data

/CreateGraph/p>

NavTeq and TeleAtlas

This file is created by default when migrating data from Navteq and TeleAtlas formats.

CreateGraph operation can be used for publishing:

additional graphs OR

to overwrite previously created graphs without publishing all files.

 

However whenever I uses RouteDataPub to create the Graph file I get the following error:

C:\Working\SDCRoutingAnalysis\NetworkData>RouteDataPub /CreateGraph /Network roads.network /EdgeCost roads.cost/EdgeReverseCost roads.cost /Output roads.length.graph /Overwrite
Error message: Exception occurred.
Description: invalid fnode
Source: AdvNetwork.GraphBuilder.1
Error code: 0x80020009

 

This is the syntax I used in cmd prompt: 

 

Create ID and Networkfile
RouteDataPub /CreateNetwork /Connection C:\Working\SDCRoutingAnalysis\data.mdb /Edge roads /ID id /Geometry geometry /Tolerance 0.01 /Output roads.network /OutputID roads.ID /Overwrite

 

Create Geometry
RouteDataPub /CreateEdgeGeometry /Connection C:\Working\SDCRoutingAnalysis\data.mdb /Edge roads /ID id /Network roads.network /Geometry geometry /Output roads.geometry /Overwrite

 

Create RangeTree
RouteDataPub /CreateRangeTree /Geometry roads.geometry /Output roads.rangetree /Overwrite

 

Create EdgeName
RouteDataPub /CreateEdgeName /Connection C:\Working\SDCRoutingAnalysis\data.mdb /Edge roads /ID id /Network roads.network /NameExpression name /Output roads.name /Overwrite

 

Create EdgeCost
RouteDataPub /CreateEdgeCost /Connection C:\Working\SDCRoutingAnalysis\data.mdb /Edge roads /ID id /Network roads.network /CostExpression blocked /Output roads.cost /Overwrite

 

Create Distance
RouteDataPub /CreateEdgeCost /Connection C:\Working\SDCRoutingAnalysis\data.mdb /Edge roads /ID id /Network roads.network /CostExpression "LENGTH(Geometry)" /Output roads.distance /Overwrite

 

Create Duration
RouteDataPub /CreateEdgeCost /Connection C:\Working\SDCRoutingAnalysis\data.mdb /Edge roads /ID id /Network roads.network /CostExpression "LENGTH(Geometry)" /Output roads.duration /Overwrite

 

Create Graph

RouteDataPub /CreateGraph /Network roads.network /EdgeCost roads.cost /EdgeReverseCost roads.cost /Output roads.length.graph /Overwrite

 

 

All of files above get created fine but the Graph file.

 

I suspect the EdgeCost and EdgeReverseCost files I generated are not qualified. in my example above I used "blocked" field for CostExpression with all values set to 0 (not a oneway). I did this because I read the data requirements below:

 

Data Format

Operation

Linear features

/CreateEdgeCost

The Cost expression specified must yield a value by combining:

Cost

Oneway value:

0 - not a oneway

1 – oneway in forward direction

-1 – oneway in reverse direction

2 – blocked both ways

 

 

This is what my roads dataset looks like:

id           name           blocked
30           road_B           0
32           road_A           0
33           road_A           0
34           road_A           0

 

 

Note: I am building new a linear network here.

 

Have I done anything wrong here?

 

 

 

Cheers

Yuan

Obvserved the same issue when playing with the sampe data and workflow...

Re: WebMap Route Service - Cannot create Graph file

Product centre indicated there might be an issue with the RouteDataPub.exe utility tool, see ticket 00032832 for more details.

Re: WebMap Route Service - Cannot create Graph file

Considering the error message, I think there might be an issue with determining the intersections in the road network. This happens in the first step, when you compile a network from your source feature class. The /Tolerance parameter controls this and should be expressed in meters.

 

What happens if you use a different tolerance value, like 1m, instead of your 0.01m?
