I know I can overlay a grid on my canvas by going to view -> decorations -> grid.

However, I want to overlay a box grid that is 50 by 50 meters. Is there a way to specify this?

CRS: WGS 84 zone 47 N
EPSG: 32647

It is a map of Thailand.

I looked at create points at 50m and creating fishnet grid.

SAGA -> vector general -> create polygons

From creating fishnet grid answer, does division width and division height correspond to meters? Is it capable of being set to a certain unit?

  • The unit of EPSG: 32647 is in meter. What is the problem with it? Look at the details here: https://epsg.io/32647 – ahmadhanb Mar 28 '19 at 04:44
  • @ahmadhanb I am not a GIS expert. I didn't know that. I just want to create a 50 by 50 meter grid overlaying the country. I am simply trying to do that. – dustin Mar 28 '19 at 04:46
  • Then use the one of the answers in the question you are referring: https://gis.stackexchange.com/questions/123444/creating-fishnet-grid-shapefile-in-qgis?noredirect=1&lq=1 to create a grid 50 x 50 m as your EPSG already in meter. – ahmadhanb Mar 28 '19 at 04:49
  • @ahmadhanb I am trying that so does that mean division height, width set to 50 would be 50x50 meters? – dustin Mar 28 '19 at 04:51

    In QGIS, use Vector -> Research Tools -> Create Grid. Set the horizontal and vertical spacing to 50. If you want polygon, select polygon under Grid type. Then run the tool. – ahmadhanb Mar 28 '19 at 04:55
  • @ahmadhanb okay, thanks. I will give that a try. – dustin Mar 28 '19 at 05:01
  • @ahmadhanb what is the difference between overlay and spacing? – dustin Mar 28 '19 at 05:07
  • Please have a look at the help: https://docs.qgis.org/3.4/en/docs/user_manual/processing_algs/qgis/vectorcreation.html#qgiscreategrid. If you need to set the grid spacing to 50 for both horizontal and vertical, just use horizontal spacing and vertical spacing, and ignore the overlay (keep the default value). Personally I did not use horizontal and vertical overlay. If you want to see the difference, you can test it with some values and see the results. – ahmadhanb Mar 28 '19 at 05:25
