Spatial Modeler Discussions

[lola5]

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?

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.

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

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

Hi, Yes I did it.

Hi,

Would you care to share how you resolved it?

Cheers,

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:
