زمینه و هدف: یکی از مهمترین داده‌های فعال سنجش از دوری برای استفاده در کمی کردن ویژگی‌های مختلف توده ها جنگلی داده‌های لایدار است. از جمله حوزه های فعال تحقیقاتی سنجش از دور، امکان سنجی برآورد زیتوده درختان با استفاده از متریک‌های مختلف داده‌های لایدار هوایی است. روش بررسی: زیتوده درختان در 127 قطعه نمونه مربعی به روش منظم تصادفی در دو منطقه کم تراکم و پرتراکم به ابعاد 900 متر مربع برای اندازه گیری موجود در قطعات نمونه برداشت شد. داده های لایدار برای یافتن وحذف هر گونه خطا بررسی، DTM [1]، DSM [2]و CHM[3] از این داده ها استخراج و شاخص های آماری مختلف از ارتفاعی داده های لایدار برای هر قطعه نمونه استخراج شد. به منظور برآورد زیتوده رگرسیون گام به گام استفاده شد. یافته‌ها: نتایج دقت متوسط برای براورد زیتوده توسط داده‌های لایدار نشان داد به شکلی که مقدار ضریب تعیین و جذر میانگین مربعات خطا (بر حسب تن در هکتار) در برآورد زیتوده با داده های لایدار برای برگ، سرشاخه، شاخه، تنه وکل درخت در کل منطقه به ترتیب (58/0 و 28)، (54/0 و 23)، (68/0 و 35/1) (68/0 و 53/1) (65/0 و 69/3) بود. بحث و نتیجه گیری: به دلیل خطای بالا در مشخص کردن نوک تاج درختان در توده های پهن برگ و مخصوصا توده های شاخه زاد به دلیل ارتفاع کم و شکل غیرهندسی تر، برآورد ارتفاع و سایر مشخصه ها در این توده ها با خطای زیادی همراه است. رسیدن به دقت‌های بالا مستلزم تحقیقات بیشتر است.
