Generate a Grid / Points around a single point
I have Baseline points. Around these points I would like to generate a grid that is a at a specified distance. Lets say that this grid will be 10km x 10km. It should have a limited amount of rows and columns for-instance 3 x 3. Please see what I mean in the attached picture.
I can generate a Fishnet and then move the grids by hand but that will be labour intensive due to the amount of Baseline points I have.

Hello,
What version of Global Mapper are you using?
It sounds like you want to start with a single point, and create a grid that is centered on that point. Correct?
Global Mapper has a function that allows you to create a grid, but the starting point is the upper-left corner of the grid.
You can get what you want by performing the following steps:- Select all of your baseline points, right-click and choose: Create Area/Polygon Feature | RANGE RING
- Click "Yes" to create range rings centered on the selected points
- On the Select Range Ring/Ellipse Parameters screen, type the radius for your grid (15 km in your example, since you want a 3x3 grid of 10 km cells), and click the check box to Create Bounding Rectangle(s) Instead of Ring(s)/Ellipse(s).
- Click OK. This will create a square area feature around each point that is 30 km x 30 km.
- Select all of the areas you created above, right-click and choose: Advanced Feature Creation Options | Subdivide Area Quadrilateral.
- On the Subdivide Areas screen, choose the number of rows and columns, and click OK.
- On the Modify Feature Info screen, under Feature Area, choose the option to create a new layer to store the created features. This will keep them separate from the boundary areas you created above.
- Click OK. This will create a grid inside each of the boundary areas.
