Download a little Visual Basic executable which will generate a regularly spaced point grid that is based on the user's inputs: min/max x,y values and the grid spacing. It is designed to generate the grid based upon UTM or State Plane coordinates. If tried with latitude/longitude, the grid will not be regular (lat/long is a spherical coordinate system and the distance between degrees varies depending on the position on the globe). As a quick example, you might need a 200m grid of points over a certain area of the world. First, get the min/max UTM coordinates for that area, type them into the text boxes on the main form, type in '200' as the spacing, and hit 'run'. The output will be a text file containing all your points (x,y, and a unique identifier). This file is named 'newgrid.txt' and can be found in the same subdirectory as this code. Download HERE. The software is free, please acknowledge the author.
