Hi how do you make something like this in Illustrator?

The dots have the same size and the space between them is fixed.

I tried halftone function but its not the effect I am looking for.

Thanks!

    While there may be an automated way (I don't know) it seems that doing this by hand wouldn't be too hard. Just start with a picture of a map, then cover it with these dots. Then hand select the ones over water and delete them. – Hanna Jan 26 '16 at 15:16
  • For this image by hand is the way to go. But I actually want to do this with more detailed shapes. – Raymond the Developer Jan 26 '16 at 15:30
  • What do you mean more detailed shapes? – Hanna Jan 26 '16 at 15:35

    This post is essentially duplicate of how-to-convert-a-monochrome-map-into-mosaic-squares with the only difference that it makes circles but that is easily remedied. – joojaa Jan 26 '16 at 15:53
  • @joojaa Less easy than you'd think. See my answer. – Vincent Jan 26 '16 at 15:56

  • Take the accepted answer: How to convert every pixel of raster picture to square objects in Illustrator? to create a mosaic of your image;
  • Double click to enter the resulting group;
  • Select one of the tiles and apply Effect > Convert to Shape > Ellipse... to it. Play with the settings to achieve a circle that is smaller than the original tile. I advise setting Size to Absolute.
  • Open the Graphic Styles palette via the Window menu;
  • Drag your ellipsified tile into the Graphic Styles palette. It will generate a new style.
  • Here comes the tricky part: use the Magic wand tool (Y) set to Fill Color to at once select all grey cells, and not the white ones. You'd achieve this by clicking with the wand on one of the grey cells. Adjust settings for the Magic Wand by double click on the tool in the toolbar.
  • Click on your new graphic style in the Graphic Styles palette.
