我有一个由.geotiff imagesat中的像素坐标定义的点。
我正在尝试将这些像素坐标转换为经度和纬度。
起初,我试图从我之前问过的反问题here改编给定的代码
def pixel_to_world(geo_matrix, x, y):
ul_x = geo_matrix[0]
ul_y = geo_matrix[3]
x_dist = geo_matrix[1]
y_dist = geo_matrix[5]
_x = x * x_dist + ul_x
_y = y * y_dist + ul_y
return (_x, _y)
def build_transform_inverse(dataset, EPSG):
source = osr.SpatialReference(wkt=dataset.GetProjection())
target = osr.SpatialReference()
target.ImportFromEPSG(4326)
return osr.CoordinateTransformation(source, target)
def find_spatial_coordinate_from_pixel(dataset, transform, x, y):
point = ogr.Geometry(ogr.wkbPoint)
point.AddPoint(float(x), float(y))
point.Transform(transform)
return pixel_to_world(dataset.GetGeoTransform(), point.GetX(), point.GetY())
ds = gdal.Open(source_directory_path + filename)
_t = build_transform_inverse(ds, 4326)
coordinates = find_spatial_coordinate_from_pixel(ds, _t, point[0], point[1])
但是我的最终坐标不正确,我得到类似[[(-1528281.9351183572,1065990.778732022),而不是带有[]的(-13.728790283203121,9.531686027524676)ul_x = -1528281.943533814,
ul_y = 1065990.7964650677,
x_dist = 0.5970709765586435,
y_dist = -0.5972870511184641
我也尝试过光栅方法,例如:
import rasterio
with rasterio.open('path/to/file.tiff') as map_layer:
pixels2coords = map_layer.xy(2679,2157)
print(pixels2coords)
Witch无法返回适当的长纬度坐标对(它返回(-1526993.7629018887,1064390.365811596)。]]我在做什么错?
我有一个由.geotiff imagesat中的像素坐标定义的点。我正在尝试将这些像素坐标转换为经度和纬度。首先,尝试从...
pixels -> lat lngs -> projected
,应该为pixels -> projected -> lat lngs
。以下内容应该起作用
