| [sumo-user] Trying to cut a map and keep edges with coordinates |
|
Hello,
I have a SUMO network. I want to cut it in a smaller network to work with, which mean keeping only the edges in a part of the map.
For that purpose, i have found 2 functions :
--keep-edges.in-boundary
(min X, min Y, max X, max Y)
--keep-edges.in-geo-boundary
From
what i understand, these functions are pretty similar except they don't accept the same type of coordinates. I tried to use Keep-edges.in-boundary which is asking Cartesian coordinate.
However,
considering that there are more than 90 results if you look for EPSG searching cartesian.
I
tried the most obvious one with EPSG4978 which basically correspond to WGS84 - Cartesian 3D Geocentric.
I
took GPS coordinates that interested me on OpenStreetMap, converted them to radian then converted them in EPSG4978 (i used Pyproj making my own code, but also online tools and it works just fine).
It cause an error telling me there is no existing edges which let me suppose i have entered the wrong
coordinate. (I have tried with absurd min and max and it does work and give me all the map).
So do i use the correct EPSG for this function ? If yes, does my process about convertion has issues ?
Any hint would be greatly appreciated,
Thanks in advance,
Lucien.
