RasterIO errors

[zags]

I'm getting inconsistent and unhelpful rasterio errors whenever I try to use this library. Running the following code:

landsat8.tile("LC08_L1TP_221078_20180625_20180626_01_RT", 11825, 18900, 15)

first gives me the error:

rio_tiler/utils.py in tile_read(source, bounds, tilesize, indexes, nodata)
222
223 else:
--> 224 with rasterio.open(source) as src:
225 vrt_transform, vrt_width, vrt_height = get_vrt_transform(src,
226 bounds)

CPLE_HttpResponseError: CURL error: error setting certificate verify locations: CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none

Running the same command again gives me

rio_tiler/utils.py in tile_read(source, bounds, tilesize, indexes, nodata)
222
223 else:
--> 224 with rasterio.open(source) as src:
225 vrt_transform, vrt_width, vrt_height = get_vrt_transform(src,
226 bounds)

RasterioIOError: '/vsis3/landsat-pds/c1/L8/221/078/LC08_L1TP_221078_20180625_20180626_01_RT/LC08_L1TP_221078_20180625_20180626_01_RT_B4.TIF' does not exist in the file system, and is not recognized as a supported dataset name.

I get this behavior on both Sentilel and Landsat. I get this on all versions of rio_tiler, ranging from 0.0.3 to 1.0rc1

I've already tried the solutions in #52 and rasterio/rasterio#1289; neither helps.

👋 Hi @zags, thanks for opening this issue.
can you try to do

$ export CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt

as explained in rasterio/rasterio#1289 and #19 ?

Please feel free to close if it solve your issue.

Setting the following fixes it for landsat:

os.environ["AWS_REQUEST_PAYER"] = "requester"
os.environ["CURL_CA_BUNDLE"] = "/etc/ssl/certs/ca-certificates.crt"

I'm still getting the error for sentinel.

sentinel2.tile("S2B_tile_20180803_22JER_0", 11825, 18895, 15)

RasterioIOError: '/vsis3/sentinel-s2-l1c/tiles/22/J/ER/2018/8/3/0/preview.jp2' does not exist in the file system, and is not recognized as a supported dataset name.

@zags this is an platform specific, do you have gdal installed, how did you installed rasterio ?

can you try gdalinfo /vsis3/sentinel-s2-l1c/tiles/22/J/ER/2018/8/3/0/preview.jp2 ?

[zags]

I do have gdal installed and rasterio was installed via PIP.

gdalinfo tells me

ERROR 15: AWS_SECRET_ACCESS_KEY configuration option not defined
gdalinfo failed - unable to open '/vsis3/sentinel-s2-l1c/tiles/22/J/ER/2018/8/3/0/preview.jp2'.

I have ~/.boto and ~/.aws/config files with my keys

[vincentsarago]

This is a configuration problem (not a rio-tiler issue). I'm really sorry. checkout http://boto3.readthedocs.io/en/latest/guide/configuration.html it might help.

[zags]

The RioTiler issue is the completely undecipherable error messages. If it's an authentication problem, this should be reflected in the resulting error

[vincentsarago]

I understand but that's a GDAL/Rasterio error.
Noticing that it might be updated with the work currently happening on rasterio/rasterio#1429

[zags]

Fixing the GDAL configuration does not solve this problem. GDAL then gives:

ERROR 4: /vsis3/sentinel-s2-l1c/tiles/22/J/ER/2018/8/3/0/preview.jp2: No such file or directory

/vsis3/sentinel-s2-l1c/tiles/22/J/ER/2018/8/3/0/preview.jp2 is being generated by RIO-tiler.
