## Brief Description

Using available image metadata, project one image onto another one

Geometry,Superimposition

## Long Description

This application performs the projection of an image into the geometry of another one.

## Parameters

- [param] -inr <string> The input reference image.. Mandatory: True. Default Value: ""
- [param] -inm <string> The image to reproject into the geometry of the reference input.. Mandatory: True. Default Value: ""
- [param] -elev <string> This group of parameters allows managing elevation values. Supported formats are SRTM, DTED or any geotiff processed by the DEM import application. Mandatory: True. Default Value: "0"
- [param] -lms <float> Generate a coarser deformation field with the given spacing. Mandatory: False. Default Value: "4"
- [param] -out <string> Output reprojected image.. Mandatory: True. Default Value: ""
- [param] -ram <int32> Available memory for processing (in MB). Mandatory: False. Default Value: "128"
[choice] -interpolator This group of parameters allows defining how the input image will be interpolated during resampling. bco,nn,linear. Mandatory: True. Default Value: "bco"

- [group] -bco

- [param] -interpolator.bco.radius <int32> This parameter allows controlling the size of the bicubic interpolation filter. If the target pixel size is higher than the input pixel size, increasing this parameter will reduce aliasing artefacts.. Mandatory: True. Default Value: "2"

- [group] -nn

- [group] -linear
