GIS hexagon grid can be created using QGIS. In this case I’m using QGIS version 2.18.15.

First of all, you must have a boundary layer. I’m using Selangor parliamentary boundary.

Steps to Create Hexagon Grid

1) Enable the Processing Toolbox

View -> Panel -> Toolbox

2) From the Processing Toolbox, select Create Grid

3) After setting the configuration as follows, click run:

• Grid type: Hexagon
• Grid extent:  Select canvas and choose Selangor boundary or your boundary layer.

• 

• Horizontal / Vertical spacing: 0.025 (means 0.025km)
• Grid CRS: EPSG 4326 (or popularly known as WGS 84 where Google Map use this CRS)

4) After click Run, a hexagon grid layer will appear as follows:

5) Select Vector -> Research Tools -> Select by Location

6) Input the Configuratoin for Select by Location as follows, then click Run:

• Layer to select: Your Hexagon Grid Layer
• Additional layer (intersection layer): Your boundary layer in my case Selangor parliamentary
• Geometric predicate: choose intersects, contains, touches, overlaps

7)Then click Select Features using an expression -> Invert Feature Selection

8)After inversion, your hexagon grid would look like below:

9) Click Toggle Editing (pencil icon) then Delete (trash icon)

10) Final output would look like this
