Re: [scikit-image] Techniques for Aligning images to GIS data

The automated approaches use other imagery as a reference. They rely on matching various scale invariant features. I'm not aware of any open implementations. It's not impossible to roll your own, but it will require significant effort and significant computing resources. Also, I'm guessing things

Re: [scikit-image] Techniques for Aligning images to GIS data

Thanks for the input Joe. What you are suggesting seems to be manual annotation, are you aware of any literature which does this automatically ? Thanks Vighnesh On Sat, Jul 1, 2017 at 9:35 PM, Ömer Özak wrote: > Hi Vigresh, > > You can try Geopandas and Georasters which are specialized package

Hi Vigresh, You can try Geopandas and Georasters which are specialized packages for GIS. Best, Ömer Sent from my mobile Please excuse any typos > On Jul 1, 2017, at 7:56 PM, Joe Kington wrote: > > You'll need to use geospatial software or libraries for this. GDAL is your > best choice. gda

Re: [scikit-image] Techniques for Aligning images to GIS data

You'll need to use geospatial software or libraries for this. GDAL is your best choice. gdal_translate with the -gcp option is what you want in this case. You can do the equivalent from gdal's Python interface, but it's a bit more involved. There's also a QGIS plugin to interactively build the GDA

Re: [scikit-image] Techniques for Aligning images to GIS data

Hello Answering Michael's questions The images I have are already ortho rectified. I don't want to co register 2 images. I want to register an image with some GIS data (like Open Street Maps). So in that sense it is the problem of registering an image with a vector of features. Thanks for the po

Re: [scikit-image] Techniques for Aligning images to GIS data

Hi Vighnesh, There was a talk by Kat Scott from Planet at PyCon 2017. It’s great and comes with a bunch of nice notebooks. I suspect it will be useful. Juan. On 1 Jul 2017, 2:16 AM +1000, K.-Michael Aye , wrote: > I don’t know your status of knowledge, so I apologize if I state the obvious. > >

Re: [scikit-image] Techniques for Aligning images to GIS data

I don’t know your status of knowledge, so I apologize if I state the obvious. Your issue is that of the co-registration of images. You have to always decide what your “prime” or “truth” is. How was your “GIS” data precisely located? How do you know it’s not that which is off? (Even so, if you h

[scikit-image] Techniques for Aligning images to GIS data

Hello Has anyone here worked with satellite images before ? I am dealing with the problem of aligning satellite images to GIS data which can be off by upto 15pixels. Could someone point me to good literature to read on the topic ? Thanks Vighnesh ___ s
