Both Landsat ARD and Landsat Collection 1 Level 2 Surface Reflectance products have pixel ranges classified as “all range” and “valid range.” We will include only pixels within valid range because negative pixel values outside the valid range will cause band index function to produce wrong re...

1. As the field FAPAR is usually derived together with the field LAI, FAPAR values on the same low-quality LAI measurement date were also excluded. Lastly, a set of 2544 LAI and 2262 FAPAR quality-controlled field records from 40 sites were selected; their distribution is shown in Fig. 2...
Operationally, lakeCoSTR allows its user to select a focal lake, for which the tool returns whole-lake summary statistics and histograms of pixel-level surface water temperature for each available Landsat scene. A “Landsat scene” is defined as an image of the Earth's surface that measures 185...
There are options for Level-1, Level-2, and Analysis Ready Data. Machine to Machine (M2M) –This API is a JSON-based REST API where you can make requests with download URLs to the Landsat inventories. The download options are the same as the USGS Earth Explorer, but M2M uses the REST...
For Landsat 7 images, the ETM' sensor has been carefully monitored since launch (Markham et al. 2004). As such, the conversion of ETM' Level 1 radiometry to at-sensor radiance was a simple matter of applying the rescaling gains and biases from the ETM' header file to the imagery. For ...

Images have various qualities that can be described in terms of their resolution. In remote sensing, we consider four types of resolution. This section provides a high-level overview, but for more detailed information check out theRS Science Deep Divesection within the Appendix of this story. ...
1. 简介 1.1 数据简介 2013年2月11日,美国航空航天局(NASA) 成功发射Landsat-8卫星。Landsat-8卫星上携带两个传感器,分别是OLI陆地成像仪(Operational Land Imager)和TIRS热红外传感器(Thermal Infrared Sensor)。 Landsat-8在空间分辨率和光谱特性等方面与Landsat 1-7保持了基本一致,卫星一共有11个波段,波段1-7,...
