I want to make simple regular point grid for a polygon but of known distance in meters between points, in QGIS using regular points research tool. How do I input my own distance? The spacing value '0.0001' is not clear what metric that is

    Can you clarify your question? For example what software are you using, what have you tried so far, and what is your input data?

  • @JimT I think it's a QGIS question.

    A tenth millimeter grid over an object measured in meters is going to be HUGE, with 100 million points per square meter. Please edit the question to specify the software you are using the objects you are sampling.

    Please edit the question to contain changes requested in comments. It's not fair to those who would answer to need to mine the comments for critical information. See the tour for a better idea how our Q&A site works.

    @rae, that number is only a default value which has the units of measurement of your CRS. It makes sense for CRS using degrees (so, it would be 0,0001 degrees of lat/lon) but, in your situation, they are assumed as meters (so, it becomes 0.0001 m). In your case, you need to insert 6000 as input value.

The Regular points tool uses 0.0001 by default and this is a value which has the units of measurement of your CRS. It makes sense for CRS using degrees (so, it would be 0,0001 degrees of lat/lon), but not for those using meters or feet as units.

Referring to your comments, it seems that you are working with a Projected Coordinate System and, if you need to generate a new point every 6 km, you should insert 6000 as input value.

This explanation is for the Point spacing/count parameter, but it also applies to the Initial inset from corner (LH side) one.
