"I’m Nancy, Product Line Manager at Pictometry. Measurement accuracy is approximately within 1% of the actual measurement. This does not take into account any error introduced from the user’s pixel placement during the measurement. So, if a measurement result 100 ft, for example, we claim between 99 and 101 feet. Thank you for your interest in Pictometry!”
