polygon_to_array returns shorter y dimension than source rasters #311

Hi @WY-CGhilardi thanks for posting. The default behavior of To start, could you try the following with your data? import geowombat as gw
with gw.open(
filenames,
band_names=['band1','band2','band3','band4','band5']
) as src:
poly_array = gw.polygon_to_array(training_polys, col="class", data=src, bounds_by="union")
print(poly_array)Are you able to share your data? |
|
Here's another test to see if the polygons are properly converted using a config context. import geowombat as gw
from geowombat.backends.rasterio_ import get_file_bounds
aoi_bounds = get_file_bounds(filenames, return_bounds=True, bounds_by='union')
with gw.config.update(ref_bounds=aoi_bounds):
with gw.open(
filenames,
band_names=['band1','band2','band3','band4','band5']
) as src:
X, Xy, clf = fit(data=src, clf=pl, labels=training_polys, col='class') |
|
Currently ml functions don't work on time series stacks, this would also require time series training data. Instead you need to set with gw.open(
filenames,
band_names=['band1','band2','band3','band4','band5'],
stack_dim='band'
) as src:
X, Xy, clf = fit(data = src, clf = pl, labels = training_polys, col='class') |
Merged

I cannot share the data but it sounds like this is a issue with how the series is stacked. For completeness here are the two configs requested above. The first returns the same results as my previous call to with gw.open(
filenames,
band_names=['band1','band2','band3','band4','band5']
) as src:
poly_array = gw.polygon_to_array(training_polys, col="class", data=src, bounds_by="union")
print(poly_array)

Do you have polygons that exceed the bounds of the images? Or that contain missing data? |
No, the polygons were explicitly drawn within this AOI. Doubling checking the bounding boxes for both the geodataframe and xarray stack check out as well

I'm not sure if it's a formatting/syntax error, but in your last post it didn't look like you wrapped the polygon conversion within the context. Are you running the following test? with gw.config.update(ref_res=3.2175):

# This needs to be indented here in order to use the config resolution
labels = polygon_to_array(training_polys, col='class', data=src)

with gw.open(

band_names=['band1','band2','band3','band4','band5']
) as src:
X, Xy, clf = fit(data=src, clf=pl, labels=training_polys, col='class')I don't have the same raster file you're using, but if I resample the array then the polygon array shape aligns. data_resamp = data.gw.transform_crs(dst_res=(3.2175, 3.2175))
poly_array = gw.polygon_to_array(

$ pip list | grep geowombat geowombat 2.1.19Originally ran into this issue when following this example in the docs
I have a time series of 5 banded imagery
This returns the following array with dimensions
20596by16400I have a
geodataframeI am loading from ageopackageWhen I try to fit a model, the resulting rasterized array is short on the y axis by one row
Looking through function definitions I was able to reproduce the mismatch with the
polygon_to_arrayfunction. This returns a20596by16399dimension arrayI realize I am not explicitly setting the
ref_resconfig parameter like in the example, but it seems to be trying to just matchsrcparameters, which seems like perfectly reasonable behavior. I am not sure if this just fails because of the non-square resolution.The text was updated successfully, but these errors were encountered:
