Özet:

 


In this research, we comparatively analyzed different interpolation methods to create soil moisture maps by
using field measurements and remotely sensed data. Impacts of number and distribution of field measurements
on interpolation procedure was also investigated. Soil moisture measurements of 36 different locations
collected from Büyükçekmece water basin and RADARSAT-1 image of the same region obtained
simultaneously on 2nd of September 2010 to create soil moisture maps of the study region. Locations of 36
field measurement points were selected considering land use/cover, soil type, elevation, spatial distribution and
accessibility to transportation lines. 25 of sample points were used as Control Points (CPs) and used for soil
moisture map creation and 11 of them were reserved and used as Independent Check Points (ICPs) to validate
the accuracy of each approach applied. Two different experiments were conducted with 25 and 15 CPs to
analyze the impact of number and spatial distribution on interpolation. Inverse Distance Weighting (IDW),
Global Polynominal Interpolation (GPI), Local Polynominal Interpolation (LPI), Radial Basis Functions
(RBF), Kriging, Cokriging and regeression methods were applied to different combination of data sets to create
soil moisture maps and obtained results were compared.
