Abstract:
1. A method of rapidly assessing population using a spatially-stratified random sample and displaying the assessed population to a user, the method comprising: creating a systematic grid on a study area, the systematic grid being defined by a given number of target grid points so as to form grid cells; dividing each one of the grid cells into a series of sub-grid cells, each one of the series of sub-grid cells being identified from left to right and from bottom to top within each one of the grid cells; identifying each one of the sub-grid cells that intersect the study area; listing each one of the sub-grid cells that intersect the study area, the list of sub-grid cells being sequences in the same order as the grid cells and the sub-grid cells; dividing the sub-grid list into a given number of sections, each of the given number of sections being configured to have substantially equal numbers of sub-grid cells, and the given number of sections being equal to the given number of targeted grid points; selecting a random sub-grid cell from each section of sub-grid cells so as to obtain the spatially-stratified random sample; using the spatially-stratified random sample to assess the population; and displaying the assessed population to the user.
