GEMI: a non-linear index to monitor global vegetation from satellites

  title={GEMI: a non-linear index to monitor global vegetation from satellites},
  author={Bernard Pinty and Michel M. Verstraete},
Knowledge about the state, spatial distribution and temporal evolution of the vegetation cover is of great scientific and economic value. Satellite platforms provide a most convenient tool to observe the biosphere globally and repetitively, but the quantitative interpretation of the observations may be difficult. Reflectance measurements in the visible and near-infrared regions have been analyzed with simple but powerful indices designed to enhance the contrast between the vegetation and other…

The Development of Vegetation Indices: a Short Overview
Vegetation indices computed from remote sensing data became key components of agricultural monitoring and assessment. With the help of these indices, the difference of vegetational and other land

A new vegetation index (ADPVI) is introduced using composite data and the result of this index is compared with one of the most popular vegetation indices (NDVI) and Experimental results demonstrate that this new index reduce the deficiencies of NDVI and also is more reliable to be representative for vegetation density.
Spectral band difference effects on vegetation indices derived from multiple satellite sensor data
Vegetation indices based on satellite image data are widely used for change monitoring but, when derived from different satellite sensors, differ as a function of the uncorrectable differences
Significant Remote Sensing Vegetation Indices: A Review of Developments and Applications
The spectral characteristics of vegetation are introduced and the development of VIs are summarized, discussing their specific applicability and representativeness according to the vegetation of interest, environment, and implementation precision.
Compositing AVHRR data for the Australian continent: seeking best practice
Daily observations of the earth by satellite sensors contain significant non-surface contributions such as cloud, atmospheric effects (aerosols, water vapour), and systematic effects resulting from
Spectral Simulations of Vegetation Indices in the Context of Landsat Data Continuity
Among the vegetation indices considered, the Global Environmental Monitoring Index (GEMI) proved to be the least sensitive to spectral dissimilarities between sensors and hence GEMI is worth considering for quantitative monitoring of environmental change using images from multiple sensors to fill the Landsat data archive.
Sensitivity of vegetation indices to different burn and vegetation ratios using LANDSAT-5 satellite data
The application of vegetation indices is a very common approach in remote sensing of burned areas to either map the fire scar or estimate burn severity since they minimize the effect of exogenous
Linearized Vegetation Indices
This book summarizes the multispectral information via vegetation and shadow–water indices and proposes a solution to the nonlinearity (saturation) problem based on this statistical explanation.
