Calculate coordinates based on pixel location.
(Thanks to the ogr cookbook!)
Parameters
| Name | Type | Description | Default |
|---|---|---|---|
gtf |
tuple | The geotransform of a grid dataset. Can be optained via the get_geotransform method. Has the following shape: (left, xres, xrot, upper, yrot, yres). | required |
x |
int | Column number of the pixel | required |
y |
int | Row number of the pixel | required |
Returns
| Type | Description |
|---|---|
| tuple | Return the x, y coordinates of the upper left corner of the cell. |
Examples
# Load a dataset
gs = fiat.io.GridSource(<some raster file>)
# Get the geotransform
gtf = gs.get_geotransform()
# Calculate the coordinates
x, y = pixel2world(gtf, <column>, <row>)
