Error in Hazard to Asset Mapping for transportation network elements

[MohamedKhoudari]

Dear R2D support team,
I hope you are doing well.

I have prepared a transportation network layer on Arcgis with all features needed for the analysis in R2D (start node, end node, max speed, number of lanes, road type, soil type, ...) and converted it to a geojson file and ensured that it was projected to WGS84 to be compatible with the format required by R2D. However, when importing it to the R2D interface in the ASD tab (option: geojson to Asset), the following error is displayed: "The CRS: defined in C:/Users/USER/Downloads/Thesis/R2D/Test3_Transportation/input_data/Roads_Network_R2D_Input8_WGS84.geojson is invalid and ignored".
Given that I have already projected my layer to WGS84, and new geojson files format defaults to CRS84 (without an explicit "crs"), I copied the following CRS statement from the example transportation geopjson file provided in R2D to my geojson file ( "crs": {
"type": "name",
"properties": {
"name": "urn:ogc:def:crs:OGC:1.3:CRS84"
}),
and I think this solved the invalid CRS error. Please let me know if this is the proper way to fix this error.

On the other hand, when attempting to select the list of "Assets to Analyze" by ID in the ASD tab for the transportation network elements (for example road of ID 1), an error message appears stating "The component ID 1 is out of range of the components provided ". Also, when running the exercise, an error is reached at the step of the hazard to asset mapping for transportation network assets.

The geojson transportation network file used and the program output log are attached below in .txt format for your reference. Could you please advise on how to proceed to resolve this error and get an error-free run?

Looking forward to hearing from you. Your guidance and support would be much appreciated.

Hi Mohamed,

1. The way you solved the invalid CRS error is perfectly correct.
2. The new error is related to the inconsistent "id" format in your input file compared to the Simcenter format convention. The first issue is that the value of "id" for each feature in the geojson format needs to be in the format of a string (e.g., "id":"1" but not "id":1). The second issue is that SimCenter's geojson does not allow using the key "id" within the "properties" field of the features.

In the attached file, I removed the "id" field in the "properties" and changed the format of the standalone"id" field to a string. The new file works with R2D without an error. A simple Python code I used to edit your file is also attached for convenience. Please let me know if you have any other questions.

Thanks and regards,

Jinyan
