Estimate Count

Measurements > Estimate Count

Estimates number of features as the total area of selected pixels in a layer divided by the average area of features in a chosen Memory Image. Essentially, it determines how many average features from the Relative To selection would fit within the layer selection. Works best for features which are difficult to separate, and which are all similar in size. Several representative features of interest should be selected in the chosen Memory Image to provide the most accurate estimated count

1. Measure Relative To

Choose which Memory Image to use to estimate the number of features. The total selected area in the image of interest is divided by the average feature area in the chosen Memory Image.
