OTB.PixelValue: Get the value of a pixel.

This application gives the value of a selected pixel. There are three ways to designate a pixel, with its index, its physical coordinate (in the physical space attached to the image), and with geographical coordinate system. Coordinates will be interpreted differently depending on which mode is chosen.

Inputs

Input image

format
href
Please set a value for in.

This will be the X coordinate interpreted depending on the chosen mode

number
Please set a value for coordx.

This will be the Y coordinate interpreted depending on the chosen mode

number
Please set a value for coordy.

Different modes can be selected, default mode is Index.

string
Please set a value for mode.

This code is used to define a geographical coordinate system. If no system is specified, WGS84 (EPSG : 4326) is used by default.
