Dear Esteemed Researchers,
I trust this message finds you well. I am currently facing a challenge in my geospatial data analysis, and I am seeking the expertise of the research community to help address the issue.
I possess a shapefile and a raster image, both of which share the same coordinate system. Regrettably, there is a noticeable displacement between the two datasets. I have undertaken the recommended step of reprojection, ensuring that both datasets adhere to a consistent coordinate reference system (CRS). Despite this, the displacement issue persists.
In light of the aforementioned challenge, I would greatly appreciate any insights, guidance, or quick/easy solutions that the research community may offer to rectify this spatial misalignment. I kindly request that suggestions refrain from involving manual digitization processes.
Your expertise is invaluable, and I am eager to explore potential methods or considerations that could contribute to a resolution.
Thank you for considering my inquiry, and I look forward to any assistance or recommendations you may kindly provide.
Sincerely,
Bilal
Dear colleague
You may have a look at our recent technical report report under my profile (key word bear). In short, resample all data layers to the DEM.
Hello Muhammad Bilal
A student of my colleague encountered similar issue previously. For his case, we eventually solved the problem by opening a new ArcGIS/QGIS project and redo all the reprojections. It seems to me the problem is quite random (at least for my case). I think you can ask your assistant to reproject the shapefile to the raster's CRS using multiple GIS softwares and see if things get better. If all fails, the most straightforward (but bruteful, not very recommanded) way is to register the datasets manually (I guess a simple offseting is enough) so that to get things moving.

Hey!
Situatuion is easy, but for You troublesome. Firstly - I would check what data is corrects? - the raster or the vector? You have to connect basemap or WMS service with the OSM project or something similar. In next step - You can: 1) just move the wrong data to the right place (by georeferencing tool); or 2) try to change the coordinate system (for example WGS-84 or Your local coordinate system) for the wrong data.
Good luck!

In my opinion, this is not a problem of coordinate systems.
Because even if the raster and vector have different but defined coordinate systems, the software will calculate it on the fly and adjust it to the system defined in the project.
here you can see that it is not a matter of stretching (other systems) but of displacement
I believe the matter is much simpler, somehow the vector data, as a whole polygon, was moved in edit mode
