What is the Economic Value of Satellite Imagery?
Does remote-sensing information, such as that from Landsat and similar Earth-observing satellites, provide economic benefits to society, and can this value be estimated? Using satellite data for northeastern Iowa, U.S. Geological Survey scientists modeled the relations among land uses, agricultural production, and dynamic nitrate (NO3–) contamination of aquifers.
The Worldwide Reference System
The Worldwide Reference System (WRS) is a global notation system for Landsat data. It enables a user to inquire about satellite imagery over any portion of the world by specifying
The Thematic Mapper
The Thematic Mapper (TM) is an advanced, multispectral scanning, Earth resources sensor designed to achieve higher image resolution, sharper spectral separation, improved geometric fidelity and greater radiometric accuracy and resolution
The Multispectral Scanner System
MSS Relative Spectral Response > The Multispectral Scanner System (MSS) sensors were line scanning devices observing the Earth perpendicular to the orbital track. The cross-track scanning was accomplished by
The Enhanced Thematic Mapper Plus
The Enhanced Thematic Mapper Plus (ETM+) instrument is a fixed “whisk-broom”, eight-band, multispectral scanning radiometer capable of providing high-resolution imaging information of the Earth’s surface. It detects spectrally-filtered radiation in

Landsat Adds Tremendous Value to Decision-Making and Bottom Line
Dr. Stephanie Hulina, President of Geospatial Data Analysis Corporation (GDA Corp) discusses how access to free Landsat imagery from USGS enables her business to provide value-added products to her company’s clients. The long-term continuity of the Landsat mission is essential to her company’s ability to maintain a competitive edge in today’s global economy.
