water everywhere in some tiles

[wurtzj]

Hello,

It seems there is an error in Geoclimate when defining some water RSU.
I am doing bounding boxes all around Europe and in some cases I get water nearly everywhere.
It seems to me that the issue could be related to the definition or the proper closure of the RSU.

Here is a tile exemple with this issue,

latitude : 55.8 - 56
longitude : -3.6 - -3.4

This figure shows the result of geoclimate rasterized. But the raw vector data depicts the same issue.
In purple WATER=0, in yellow WATER=1.

Thank you for your help,

Kind Regards,

Jean

I have identified very close cases where one is working and the other has the bug identified.

Below are the two config files:
A minimum example with the error

{
    "description": "Processing OSM data",
    "input": {
    	"area" : 100000,
    	"timeout": 9000,
	"maxsize":4294967296,
        "locations": [
            [55.995,-3.56, 56, -3.4]
        ]
    },
    "output": {
        "folder": "/tmp"
    },
    "parameters": {
        "rsu_indicators": {
            "indicatorUse": [
                "LCZ",
                "TEB"
            ],
            "svfSimplified": true,
            "estimateHeight": true
        }
    }
}

A minimum example without error

{
    "description": "Processing OSM data",
    "input": {
    	"area" : 100000,
    	"timeout": 9000,
	"maxsize":4294967296,
        "locations": [
            [55.995,-3.555, 56, -3.4]
        ]
    },
    "output": {
        "folder": "/tmp"
    },
    "parameters": {
        "rsu_indicators": {
            "indicatorUse": [
                "LCZ",
                "TEB"
            ],
            "svfSimplified": true,
            "estimateHeight": true
        }
    }
}

To @ebocher as you can see there is a quite narrow strip of land which is causing the error but I have not identified which geographical feature may be the cause of the problem. Any idea ?

Hello all,

Here is an other example near the coast where coast and land seems reversed.

Thanks,

Can you share the coordinates ?

Step-by-step investigations are necessary.

Here there are :

Longitude 15,6E - 16E
Latitude 68,4N - 68,6N

I was making 0.2x0.2° tiles, but it seems the bug here is on two tiles.

I have tried with older versions of GeoClimate, none of the ones I have from 2023-10 works. This is a quite a good news since it means new versions do not add new issues.
