Using Landsat data acquired between and , Masek and Lindsy mapped the growth of the Washington D.C. metropolitan area. They found that the Washington area has expanded at a rate of square miles (22 square kilometers) per year with notably higher growth during the late s, a trend that followed the regional and national economy. The Landsat program is the longest-running enterprise for acquisition of satellite imagery of is a joint NASA/USGS program. On J the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. The most recent, Landsat 8, was launched on Febru The instruments on the Landsat satellites have acquired millions of images. Monitoring urban development using satellite images human settlements typify the most dynamic regions on earth. To cope with this development urban planning and management requires up-to-date. Landsat is the Earth Observatory System (EOS) satellite series that has been providing data since the s. Landsat satellites are considered a valuable source of observation and monitoring of global changes because of the medium spatial resolution and the availability of long-term data (Masek et al. ; Wulder et al. ).For decades, data from Landsat have been widely used by scientists Cited by: 5.
Landsat data constitute the longest record of global-scale medium spatial resolution earth observation data. As a result, the current methods for large area monitoring of land cover change using medium spatial resolution imagery (10–50 m) typically employ Landsat data. Most large area products quantify forest cover by: Nairobi city expanded spatially leading to the formation of km 2 Nairobi Metropolitan Area. The region faces rapid urbanization challenges and lacks reliable data for urban planning. This study is aimed at monitoring the urban land cover using GIS and Remote Sensing techniques. Three different land cover maps produced at ten year epochs between and were used to evaluate Author: Monica Machuma Katyambo, Moses Murimi Ngigi. Landsat Program In the mid’s, the National Aeronautics and Space Administration (NASA) embarked on an initiative to develop and launch the first Earth-monitoring satellite to meet the needs of resource managers and earth scientists. The U.S. Geological Survey (USGS) entered into a partnership with NASA in the early ’s to assume File Size: 22KB. The Landsat mission provides the longest continuous space-based record of Earth’s land, dating back to and the Landsat 1 satellite. Starting with Landsat 4, each of the satellites imaged the Earth’s surface at a meter resolution about once every two .
The Landsat satellites make loops around the Earth and are constantly collecting images of the surface through the use of a variety of sensing devices. Since the beginning of the Landsat program in , the images and data have been available to all countries around the world. Landsat data is free and available to anyone on the : Matt Rosenberg. LANDSAT AND THE RISE OF EARTH RESOURCES MONITORING. Disagreements among users made it difficult to design the satellite and resulted in only weak support from users when funding decisions were made. 4 These factors, plus a lack of strong leadership in the project after its earliest years, left it caught in limbo without sufficient funding to realize the potential it had demonstrated. The Greater Toronto Area is the most vital economic centre in Canada and has experienced rapid urban expansion in the past 40 years. This research uses Landsat images to detect the spatial and temporal dynamics of urban expansion in the Greater Toronto Area from to We quantitatively analyzed. In the mid's, the National Aeronautics and Space Administration (NASA) embarked on an initiative to develop and launch the first Earth monitoring satellite to meet the needs of resource managers and earth scientists. The U.S. Geological Survey (USGS) entered into a partnership with NASA in the early ?s to assume responsibility for archiving data and distributing data products.
