Create a bounding box from point shapefile

Question

I have a BigTiff image and an associate point shapefile with features. I would like to know how can I create a bounding box from that shapefile to create/clip images around that points to train a model.

EDIT: I'm trying to do it automatically in a Jupyter Notebook and I've followed this threat but all exported images are completely black.

from osgeo import ogr, gdal

InputImage = 'XXX.tif'
Shapefile = 'XXX.shp'
RasterFormat = 'GTiff'
PixelRes = 0.5
VectorFormat = 'ESRI Shapefile'

# Open datasets
Raster = gdal.Open(InputImage, gdal.GA_ReadOnly)
Projection = Raster.GetProjectionRef()

VectorDriver = ogr.GetDriverByName(VectorFormat)
VectorDataset = VectorDriver.Open(Shapefile, 0) # 0=Read-only, 1=Read-Write
layer = VectorDataset.GetLayer()
FeatureCount = layer.GetFeatureCount()
print("Feature Count:",FeatureCount)

# Iterate through the shapefile features
Count = 0
for feature in layer:
    Count += 1
    print("Processing feature "+str(Count)+" of "+str(FeatureCount)+"...")

    geom = feature.GetGeometryRef() 
    minX, maxX, minY, maxY = geom.GetEnvelope()
    xmin, ymin = minX - 50, minY - 50
    xmax, ymax = maxX + 50, maxY + 50

    # Create raster
    OutTileName = str(Count)+'.SomeTileName.tif'
    OutTile = gdal.Warp(OutTileName, Raster, format=RasterFormat, outputBounds=[xmin, xmax, ymin, ymax], xRes=PixelRes, yRes=PixelRes, dstSRS=Projection, resampleAlg=gdal.GRA_NearestNeighbour, options=['COMPRESS=DEFLATE'])
    OutTile = None # Close dataset

# Close datasets
Raster = None
VectorDataset.Destroy()
print("Done.")

Moreover, I feel this is not the most simple or efficient way to do the bounding box.

Answer 1

From the Processing Toolbox run the "Extract layer extent" algorithm.

Answer 2

I advise you to use rasterio library for raster's manipulations. Here you have the command to easily extract the bounding box of your raster.
