محتوای آب خاک (درصد حجمی) برای مکش های 33 کیلو پاسکال و 1500 کیلو پاسکال پیش بینی شده در 6 عمق استاندارد (0، 10، 30، 60، 100 و 200 سانتی متر) در وضوح 250 متر
نقاط آموزشی بر اساس یک مجموعه جهانی از پروفایل های خاک است:
مراحل وارد کردن داده در اینجا موجود است. مراحل پیش بینی فضایی به تفصیل در اینجا شرح داده شده است. توجه: اینها در واقع مقادیر محتوای خاک اندازه گیری و نقشه برداری شده اند. هیچ تابع انتقال Pedo استفاده نشده است (به جز برای پر کردن چگالی فله NCSS از دست رفته). ظرفیت آب موجود بر حسب میلی‌متر (به‌عنوان تفاوت بین ظرفیت مزرعه و نقطه پژمردگی ضربدر ضخامت لایه) در هر لایه در اینجا موجود است. قطب جنوب شامل نمی شود.
