What can I do on "epsg code not found" error?

[kochizufan]

Hi I ran geocesiumtiler on Windows, like this:

F:\challenge>F:\challenge\gocesiumtiler.exe -i F:\challenge -o F:\challenge\3dtiles -e 7415 -g -f -r

2022/04/26 11:34:08 epsg code not found

It said "epsg code not found". How can I define new CRS? Is it OK to write proj text just after -e switch?

Probably you can just add a new definition to this file https://github.com/mfbonfigli/gocesiumtiler/blob/master/assets/epsg_projections.txt using a proj4 string. Please let me know if this worked

[mfbonfigli]

Basically in your case you can try to add a line to that file like:

EPSG:7415   EPSG:7415: Amersfoort / RD New + NAP height +proj=sterea +lat_0=52.15616055555555 +lon_0=5.38763888888889 +k=0.9999079 +x_0=155000 +y_0=463000 +ellps=bessel +towgs84=565.417,50.3319,465.552,-0.398957,0.343988,-1.8774,4.0725 +units=m +vunits=m +no_defs 

and see if it works.

If it does please consider submitting a Pull Request or at least letting me know :)

Closing as it's a stale issue that has already been answered.

Hello, I also encountered this problem. I added my epsg code as @mfbonfigli 's solutions. But I still get the epsg not found error.

EPSG:5254 EPSG:5254: TUREF / TM30 (Turkey) (deg) +proj=tmerc +lat_0=0 +lon_0=30 +k=1 +x_0=500000 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs +type=crs

Do I need to do anything else? Were you able to resolve this issue?

Hello, to temporarily solve this issue, I converted my coordinates to EPSG:4326 using Laspy. However, I want to work in my original coordinate systems, EPSG:5254 or EPSG:5256, without performing this conversion.
