Spatial Modeller - Orthorectification with control points

Hi,

 

Is it possible to create a spatial model that orthorectifies an image based on existing input & reference control point files? I have many images that each have an associated sensor model, dem file & input and reference coordinate files (.gcc). 

 

I am looking for an efficient way to orthorectify these images without having to open the Multipoint Geometric Correction tool and load all these inputs manually.

 

Is this something Spatial Modeller could do?

Re: Spatial Modeller - Orthorectification with control points

Hi Lola,
Currently it is not possible to Orthorectify images with camera models in Spatial Modeler because only RPCs are currently supported as sensor models.

 

FYI, in other 2D transform types, Spatial Modeler supports only Affine, Polynomial, Rubbersheeting (Linear and Non-Linear) transforms.

Re: Spatial Modeller - Orthorectification with control points

Hi Partha,

I would like to Orthorectify images (with RPCs), in the spatial modeler, using CGP. 

Is there any model example that I can use to start some tests?

thank you very much

Regards

Did you reolve that gmaldera? . I have the same issue.

I'm working with Giuseppe on that.

The following Spatial Model may be helpful in regard to the request to use GCPs to perform orthorectification in Spatial Modeler:
