ОВЕРЛЕЙНИЙ АНАЛІЗ ЯК ЗАСІБ
ЗАБЕЗПЕЧЕННЯ ІДЕНТИФІКАЦІЇ
ЛАНДШАФТІВ ПРИРОДООХОРОННОЇ
ТЕРИТОРІЇ
Овчаренко А. Ю.
ХНУ ім. В. Н. Каразіна
Факультет геології, географії, рекреації і туризму
науковий керівник:
проф., доктор техн. наук Черваньов І. Г.
Науковий консультант:
канд. геогр. Наук Бодня О. В.
1
Створення бази даних ландшафтного
картографування:
2
Продовження 1
3
Знімки Landsat 8
Рослинний покрив
Некерована класифікація
4
5
Керована
класифікація
Атрибутивні дані (по тематичних шарах)
(усього 7991 одиниць контурів)
Атрибутивна таблиця до тематичного шару ґрунтового покриву
6
 Атрибутивні таблиці містять інформацію про
форми рельєфу, четвертинні відклади, ґрунтовий
покрив та наявні рослинні угруповання кожного
контуру.
Об’єднання тематичних шарів
(Overley→Intersect)
Надає можливість
поєднання тематичних
шарів шляхом їх
просторового
співставлення
7
Об’єднання атрибутивної інформації для
кожного контуру в одному стовпці таблиці
Використання інструменту
Field Calculator
Для поєднання стовпців «Форми рельєфу»,
«Четвертинні відклади», «Ґрунти»,
«Рослинність»
8
Об'єднання за спільним атрибутом
(Geoprocessing →Dissolve)
та перевірка отриманих контурів
 Використання інструменту
Dissolve дозволило уникнути
повторів різних типів фацій в
атрибутивній таблиці. Таким
чином, загальну кількість контурів
(7 991) вдалось поєднати в 129
типів фацій.
9
Польові методи дослідження
10
 Перевірка отриманих контурів
проводилася польовими
методами:
 з використанням
стандартних бланків опису
фації за формою №1
«Лісова, чагарникова і
болотна»;
 з використанням інструменту
ArcGIS for Windows Mobile
«Збір даних» (Create
Inspection Report).
11
Висновки
 Застосування інструментів оверлейного аналізу в
ArcGIS 10.2 та даних ДЗЗ дозволяє суттєво
прискорити і значно спростити процес
ландшафтного картографування в камеральних
умовах для укладання ландшафтної карти-
гіпотези.
