I am trying to use Reader.ept to access data via a URL.

The URL works fine and I can visualize the number of points in the polygon. However when I try to use a pipeline to access the points and generate a surface, I get a curl failure. I am using PDAL in a Jupyter notebook following this https://colab.research.google.com/drive/1JQpcVFFJYMrJCfodqP4Nc_B0_w6p5WOV?usp=sharing#scrollTo=wQtbyo9bgeOa

Code below

for index, row in tiles_mec.iterrows():

id = row ['tile_id']

resolution = 1
useful_classes = "Classification[0:6],Classification[17:17],Classification[9:9],Classification[10:10],Classification[11:11],Classification[2:2]"

#fetch all points and create full dsm
reader = pdl.Reader.ept(url, 
                     resolution=resolution, 
                     polygon = row['geometry'].wkt)
rng = pdl.Filter.range(limits=useful_classes)
z = pdl.Writer.gdal(out_fdsm + id +"_rfdsm_r1.tif", 
                resolution=resolution, 
                dimension="Z", 
                data_type="float32", 
                output_type="mean",
                nodata=-9999)

pipeline = reader | rng | z
pipeline.execute()

Error:

Curl failure: Timeout was reached

It's just a warning that was being emitted by PDAL when it was retrying its fetches. You can ignore it.

It should have been fixed in PDAL 2.6.0.
