Introduction

The USGS Integrated Vegetation Mapping Viewer provides a dynamic online map interface that can be used to view a suite of satellite-derived vegetation condition datasets, integrated with information from The National Map.

Data Available:

The primary dataset is Greenness based on the Normalized Difference Vegetation Index. The secondary datasets are Relative Greenness, Departure from Average, Fire Potential (experimental), Seasonal Greenness and Percent of Seasonal Greenness.

Data Range:

Layers are available for the United States, including Alaska and Hawaii.

Data layers have variable time ranges.

Location/existence of archives is unknown

Data Collection:

?how/from whom the raw data is collected, and how/where it is stored (on server or distributed)?

The vegetation condition information is derived from Advanced Very High Resolution Radiometer (AVHRR) data as part of the Conterminous US Greenness Mapping project and associated research activities.

Data Analysis:

?how/with what data predictions are made (if applicable)?

Presentation/Features:

?map features, software used?

The Map Information and Metadata button will display details on the current extent, scale, image, etc. of the map view, and if available, information on the individual data sets displayed in the view.

The print map button will produce a map that shows the same area, and the same layers in a new browser window.

The download button will allow the user to pick from a set of data sets available for download and will open a new window to the SDDS/E download interface for the selected data set.

Users:

The dataset selection is intended to support wildland fire management, drought monitoring, and agricultural assessment applications.
