The MODIS/VIIRS Global Subsetting and Visualization Tool provides on-demand, customized subsets of several MODIS Collection 6 and VIIRS (Version 001) land products. Data are available to the user through an interactive web page. The user specifies data product of interest and the area of interest by entering geographic coordinates or selecting the location on a map. Data are provided in either the native sinusoidal or geographic (WGS84) projection. Subsets are processed and delivered to the user via email. To view and download the data order, a user is provided with a custom order visualization page with interactive time series plots, data quality information, land cover and phenology data, order and product citations, and download access for the data in tabular and spatial data formats.
