Systems, devices, applications, and methods for generating an open area map are disclosed. For example, a software application is configured to run on a computing platform of an end user. The end user generates an image of a layout of a walkable area. The software application performs a method of generating an open area map based on the image. The method includes applying an array of uniformly spaced objects on the image. A routable map is generated as a function of the array. The routable map is configured to provide point-to-point routing within the layout.
