Indices Ndvi(指數 Ndvi)到底是什麼?
Indices Ndvi 指數 Ndvi - The indices NDVI, NDRE, GNDVI, GRNDVI, and PNDVI were used, with changes proposed in the equations of the indices GRNDVI and PNDVI, in which the red wavelength was replaced by the red edge. [1] The indices NDVI, RE-OSAVI, and REMCARI were used with Sentinel-2A images. [2]使用了指數 NDVI、NDRE、GNDVI、GRNDVI 和 PNDVI,並在指數 GRNDVI 和 PNDVI 的方程中提出了變化,其中紅色波長被紅色邊緣取代。 [1] 指數 NDVI、RE-OSAVI 和 REMCARI 用於 Sentinel-2A 圖像。 [2]
Vegetation Indices Ndvi 植被指數 Ndvi
Seven broad-band vegetation indices NDVI, NDRE, ClGreen (GCI), CCCI, CVI, GNDVI, MCARI were used in the study, estimating changes in chlorophyll a and b content in soybean leaves. [1] 8 Wien, the vegetation indices NDVI and NDWI were used to classify agricultural, pasture and forest areas by biome. [2] With the help of satellite images of the Terra/Modis spectroradiometer, we determined the burnt areas and vegetation indices NDVI and EVI for the territory of Tsasuchey pine forest. [3] Second, for the crop segmentation we developed a website, in which we have calculated vegetation indices NDVI, SAVI, OSAVI. [4] This study aimed to estimate the biomass potential of nypa palms, calculate the relationship between vegetation index and palm biomass content, and compare the vegetation indices NDVI and GNDVI. [5] Vegetation indices NDVI and GNDVI as well as biophysical parameters LAI and FAPAR were calculated from Sentinel-2 bands using the SNAP Sentinel2 ToolBox. [6] The set of vegetation indices NDVI and its modifications is justified. [7] In addition, the analysis of the FPAR inversions of different vegetation indices showed that the inversion accuracies of the red-edge vegetation indices NDVIred-edge and SRred-edge were higher than those of the other vegetation indices, which confirmed that the vegetation indices involving red-edge information can more effectively retrieve FPAR and aboveground biomass of crops. [8] The methodology is based on Circular Hough Transform (CHT) and Balanced Random Forest (BRF) classifier using vegetation indices NDVI/SAVI generated from Landsat 8 images and Land Use and Land Cover (LULC) data provided by project MapBiomas. [9] As a first step towards the quantification of its causes and consequences, we here assess anomalies of atmospheric circulation patterns, temperature loads, and climatic water balance as potential drivers of ecosystem responses as quantified by remote sensing using the MODIS vegetation indices NDVI and EVI. [10] The significant differences in brightness values and vegetation indices NDVI and MSI between diseased and healthy areas were determined. [11] When December and January were excluded from the analysis the negative correlations between vegetation indices NDVI, OSAVI and SR and red AGB remained significant (r = −0. [12]研究中使用了 7 個寬帶植被指數 NDVI、NDRE、ClGreen (GCI)、CCCI、CVI、GNDVI、MCARI,估計了大豆葉片中葉綠素 a 和 b 含量的變化。 [1] 8 Wien,植被指數 NDVI 和 NDWI 用於按生物群落對農業、牧場和森林區域進行分類。 [2] 借助 Terra/Modis 光譜儀的衛星圖像,我們確定了 Tsasuchey 松林境內的燒毀面積和植被指數 NDVI 和 EVI。 [3] 其次,對於作物分割,我們開發了一個網站,我們在其中計算了植被指數 NDVI、SAVI、OSAVI。 [4] 本研究旨在估計睡蓮棕櫚的生物量潛力,計算植被指數與棕櫚生物量含量的關係,並比較植被指數NDVI和GNDVI。 [5] 植被指數 NDVI 和 GNDVI 以及生物物理參數 LAI 和 FAPAR 使用 SNAP Sentinel2 工具箱從 Sentinel-2 波段計算。 [6] 這組植被指數 NDVI 及其修改是合理的。 [7] 此外,對不同植被指數的 FPAR 反演分析表明,紅邊植被指數 NDVIred-edge 和 SRred-edge 的反演精度高於其他植被指數,證實了涉及紅邊的植被指數-邊緣信息可以更有效地檢索農作物的FPAR和地上生物量。 [8] 該方法基於循環霍夫變換 (CHT) 和平衡隨機森林 (BRF) 分類器,使用從 Landsat 8 圖像和 MapBiomas 項目提供的土地利用和土地覆蓋 (LULC) 數據生成的植被指數 NDVI/SAVI。 [9] 作為量化其原因和後果的第一步,我們在此評估大氣環流模式、溫度負荷和氣候水平衡的異常,作為生態系統響應的潛在驅動因素,使用 MODIS 植被指數 NDVI 和 EVI 進行遙感量化。 [10] 確定了病區和健康區之間亮度值和植被指數 NDVI 和 MSI 的顯著差異。 [11] 當 12 月和 1 月被排除在分析之外時,植被指數 NDVI、OSAVI 和 SR 與紅色 AGB 之間的負相關仍然顯著(r = -0.
