Last week we looked at Sentinel imagery coverage and today we are doing the same for Landsat imagery. First, note that we are discussing Landsat 8 imagery only, as Landsat 7 imagery is not currently available on Amazon Web Services (AWS), which is the source of our information. In addition, we have excluded Landsat imagery […]
Creating Satellite Imagery - Landsat: Introduction Creating satellite imagery is quite easy and really a lot of fun. You can see the world in a completely different way. Not to mention, some of those images make for a great desktop background! :) In this tutorial, we're going to focus…

An Atlas 5 successfully launched the latest Landsat Earth science satellits Sept. 27, continuing a program that started nearly 50 years ago.
The Landsat program began in 1972 and is the longest-running operation of its kind. This satellite is the ninth in the program and uses optical and thermal sensors to capture images of the Earth.

Every eight days, a Landsat satellite carrying delicate sensing and scanning equipment passes high above wherever you might be on the planet. Data from Landsat mission images records changes on Earth’s surface since 1972, over the last four decades, and it’s freely available.

NASA's first Landsat mission launched in July 1972. Seven more satellites have been launched since. Two of these, Landsat 7 & 8, are still active. The progra...
Agricultural satellite photo of Parana, Brazil was taken with the Landsat Satellite at 15-meter resolution.
We told you earlier this year about the launch of the Landsat 8 satellite and now the first images captured by that satellite are starting to arrive. NASA’s Landsat Data Continuity Mission (LDCM) page has quite a bit of detail about the imagery including the following: But the work is only beginning for validating the […]

Desertification is a serious threat to the ecological environment and social economy in our world and there is a pressing need to develop a reasonable and reproducible method to assess it at different scales. In this paper, the Ordos Plateau in China was selected as the research region and a quantitative method for desertification assessment was developed by using Landsat MSS and TM/ETM+ data on a regional scale. In this method, NDVI, MSDI and land surface albedo were selected as assessment indicators of desertification to represent land surface conditions from vegetation biomass, landscape pattern and micrometeorology. Based on considering the effects of vegetation type and time of images acquired on assessment indictors, assessing rule sets were built and a decision tree approach was used to assess desertification of Ordos Plateau in 1980, 1990 and 2000. The average overall accuracy of three periods was higher than 90%. The results showed that although some local places of Ordos Plateau experienced an expanding trend of desertification, the trend of desertification of Ordos Plateau was an overall decrease in from 1980 to 2000. By analyzing the causes of desertification processes, it was found that climate change could benefit for the reversion of desertification from 1980 to 1990 at a regional scale and human activities might explain the expansion of desertification in this period; however human conservation activities were the main driving factor that induced the reversion of desertification from 1990 to 2000.
