Spatial Modeler Discussions

[cbmccann3]

Hi there,

I am trying to create an spatial model that will allow me to preform an atmospheric correction on worldview-3 data. In the spatial modeler it seems that it is having issues recognizing the companion metadata for worldview3 which is a .imd file. Does anyone have experience preforming and ATCOR on WV-3 data? I am new to this program and it seems like the is limited resources available in terms of information. Any information or suggested workflows would be greatly appecaited!

Thanks for the help!

This is aslo my first time posting on a forum like this, if there are any suggestions that could help me pose a question here in the future, just let me now!

Hi cbmccann3,

Welcome to the discussion boards!

Do you have access to the .XML header file? That's working for me:

How many bands does your WV-3 image have? It must have 4 or 8 bands to work with Rapid Atmospheric.

IMD is working for me too. So I do wonder how many bands your data has? Also, when you feed the raster stream to Rapid Atmospheric is it still u16? If not you'll need to convert it. If things still aren't working - what error message are you seeing? What does your model look like?

Oh, and what version of ERDAS IMAGINE? ERDAS IMAGINE 2018 Update 2?

Cheers

Hi cbmccann3,

since your are running a model and mention ATCOR I assume you are referring to ATCOR Workflow for IMAGINE.

Basically WV3 should work in ATCOR Workflow for IMAGINE reading the IMD as metadata as you have described.

Please find documentation, Tour Guide and Example Data on our website

ATCOR Workflow for IMAGINE is a product of GEOSYSTEMS and supported through us or your local reseller.

Could you please submit a support incident regarding this to either of us.

I kindly ask you to provide us also the .log-file of ATCOR Workflow. It contains detailed information about the ATCOR process including warnings and error messages.  It is named after the input file and can be found in your ATCOR project folder (together with a calibration file ‚.cal‘ and a sub-folder ‚_Repository‘).

You can also add a screenshot of your spatial model after running it.

Thank you,

Eva
