| Jan 26, 2017 at 19:40 | comment | added | Kazuhito | I am afraid reprojecting raster causes the changes to the cell value, so I would not recommend. Switching Project CRS would be easier than reprojection and does not affect the original raster. | |

| Jan 26, 2017 at 11:03 | comment | added | Kazuhito | @ADorsch Thanks :) I likely misread your previous comment. My apologies. | |
| Jan 26, 2017 at 11:00 | comment | added | ADorsch | @kazuhito Yes you are right of course! The reprojection needs to be done in advance, before running the tool! Changing the values in the attribute table in the shape would only be possible by using the adequate algorithm to transform coordinates from one CRS into another, though... | |
| Jan 26, 2017 at 10:43 | comment | added | Kazuhito | @ADorsch If you are talking about the (Actions) parameters, yes, it keeps raster CRS and it can be latlong. By the way, from my limited experience reprojection did not renew the attribute data created/stored by this tool. | |
| Jan 26, 2017 at 7:09 | comment | added | ADorsch | I think it depends on the CRS of your target raster layer! If this is in lat-lon (e.g. WGS84), this tool should automatically take the according coordinates as X-lon, Y-lat, regardless of your project CRS. You can reproject your raster layer using "Raster -> Projections -> Warp(reproject) function!" | |
| Jan 26, 2017 at 1:42 | comment | added | Kazuhito | This tool takes up the Project CRS. Please switch to geographical coordinates (such as WGS84, EPSG:4326) before running this tool. As long as your Project CRS stays in latlong, the (Derived) parameters will show X-Longitude and Y-Latitude. Meanwhile (Actions) parameters will always show XY of the original layer's CRS. | |
| Jan 25, 2017 at 15:05 | comment | added | jdeere9750 | Thanks! This is very close to what I need. Is it possible to get actual latitude and longitude instead of the x,y coordinates? | |
