  • You are on the mountains and you are geocoding your data, not orthorectifying it.
    You should orthorectify it instead.

  • Dear dan,
    i met nearly the same problem.
    I choose a GCP and set it.
    i have checked the DEM file via visualization and it seems fine.
    the location of GCP is correct in reflectivity map and in google earth.
    However, the geocoding reflectivity map is offset far from the right location.
    Please have a look with the attached files.
    Thanks,
    Regards,
    Qingli

    the dem was all fine, but the second point helped to load it at a correct position, thank you!
    I however noticed that the subset in the “SLC Data Import” wasn’t applied correctly so that confused me a lot 😀 Was probably my fault, I’ll run it again with the correct subset.

    1. check that you have a DEM correctly loaded. to check it, you can click “dem visualization” in the frame “preliminary geocoding” in “site processing”. if you get a green flat picture, probably it failed downloading SRTM data (you should have got messages about that). In such a case delete the corresponding SRTM files (SRTM directory in the…[Read more]

    Please check the MCR version and make sure it’s the 8.3. Here the full list https://www.mathworks.com/products/compiler/mcr.html
    Uninstall it and re-install it again.
    Check also the path of your pc (environment variables) and make sure the MCR location is present
    It should be something like this: C:Program FilesMATLABMATLAB Compiler…[Read more]

    Dear all, I use 16 Sentinel-1 SLC scenes (same track) for change detection analysis.
    I followed the tutorials I and II for data import. Master selection and coregistration worked well but I keep struggling with the GCPs as the scene is always shifted to a large degree (please see screenshot below).

    Do I miss anything that is not contained in…[Read more]

    Hello,
    I re-installed windows 10 in my computer, and when I installed MCR and run SARPROZ I got this message: “Could not find version 8.3 of the MCR Attempting to load mchmcrt8.3dll. Please install the correct version of the MCR. Contact your vendor if you do not have an installer for the MCR.”

    How can I solve this problem?
    Best regards

    Hi Cecilia,
    yes, on the manual you find some explanation, here in particular http://sarproz.com/manual/geocod.html
    what you have written is correct if no correlation with temperature was estimated. If on the contrary you did remove a temperature-correlated trend, then you have to tick on the corresponding box to see it, otherwise it is removed…[Read more]

  • Hello,
    I got maybe a stupid question but I got suddenly unsure.
    So when in Geocoding (Small processing) I click on “Data series” I get the time series of the point but, please correct me:
    -if I do not tick anything I get the residues phase, which is the phase minus the topographic and the movement component
    -if I tick “mov” I add the movement…[Read more]

  • Hello,

    It would also be nice to see the jpeg image of the master in your FITTED folder. Could you share that as well? You can upload the jpeg file to wetransfer and paste the link here.

  • I m having error “cull_points: fewer than minimum points” in 15 images. Im using the version 18-sep-2017, my master image has no rain/snow and and area of 20km radius, also already try orbit and coarse xcorr. co-registration but with the same outcome error

  • Yes. We closed this issue but forgot to post the solutions here.

    There were several errors/messages mentioned in this post. Which one exactly are you getting?

    We have fixed all the errors that were discussed in this post, so the first thing is to make sure you have the newest version of sarproz.

    Then please let us know which error you are…[Read more]

  • Did any solution came from this post? Im facing the same problem cull points:fewer than minimum points

    Dear all,

    last week we discovered a change in the policies/formats of the website from where Sarproz is downloading weather data (wunderground.com). With old software version you will not be able any more to download weather data.
    Wunderground is now requiring to register on their webpage to get an API code to download weather data.

  • periz replied to the topic Reference point in the forum Sarproz Forum 1 week ago

    You can choose any parameter for your reference selection: temporal or spatial coherence, amplitude stability index, reflectivity map or whatever.
    Or you can even pick it up manually (ticking the corresponding box) depending on other infos/observations (e.g. you want it on the ground, in a stable area or whatever).
    InSAR is a differential…[Read more]

    Hi
    I’ll appreciate you if answer my question:
    Which parameters should i choose in “small area processing > multi image analysis” module where is located in “reference point” section? And why the results varies with choosing different parameters of reference point?

    Thanks and best regards
