چکیده

Pada daerah yang luas biasanya terdapat kesulitan dalam memantau fase tumbuh tanaman padi. Seiring dengan berkembangnya teknologi, salah satu alternatif dapat dilakukan untuk memperoleh data tersebut adalah menggunakan citra satelit. Fase padi diketahui menghitung indeks vegetasi berdasarkan tingkat kehijauan bantuan MODIS algoritma NDVI. Tujuan dari penelitian ini menentukan persamaan dan rentang nilai NDVI memprediksi tahap pertumbuhan di Kecamatan Sungai Tarab Kabupaten Tanah Datar. Dalam pengambilan data, pengamatan lapangan pada lokasi pixel ≥50% sawah. Pengamatan validasi koordinat sampel pengamtan, kesesuaian penggunaan lahan, umur padi, varietas Dari hasil analisis, diperoleh yaitu y = -0.0001011274 x 2 + 0.0128987956 0.3189628155 dimana (HST) (NDVI). Rentang air ≤ 0,4797; vegetatif 1 0,4797-0,6149; 0,6149-0,7300; generatif 0,7300-0,6379; 0,6379-0,5142 bera 0,5142-0,2868

Multifractal Downscaling of Rainfall Using Normalized Difference Vegetation Index (NDVI) in the Andes Plateau

In this paper, a multifractal downscaling technique is applied to adequately transformed and lag corrected normalized difference vegetation index (NDVI) in order to obtain daily estimates of rainfall in an area of the Peruvian Andean high plateau. This downscaling procedure is temporal in nature since the original NDVI information is provided at an irregular temporal sampling period between 8 a...

Preliminary comparison of landscape pattern-normalized difference vegetation index (NDVI) relationships to Central Plains stream conditions.

We explored relationships of water quality parameters with landscape pattern metrics (LPMs), land use-land cover (LULC) proportions, and the advanced very high resolution radiometer (AVHRR) normalized difference vegetation index (NDVI) or NDVI-derived metrics. Stream sites (271) in Nebraska, Kansas, and Missouri were sampled for water quality parameters, the index of biotic integrity, and a hab...

Global Trends in Seasonality of Normalized Difference Vegetation Index (NDVI), 1982-2011

A 30-year series of global monthly Normalized Difference Vegetation Index (NDVI) imagery derived from the Global Inventory Modeling and Mapping Studies (GIMMS) NDVI3g archive was analyzed for the presence of trends in changing seasonality. Using the Seasonal Trend Analysis (STA) procedure, over half (56.30%) of land surfaces were found to exhibit significant trends. Almost half (46.10%) of the ...
