getLST8: Retrieves OLI & TIRS raw values and calculates REFLECTANCE...

In rbarango/LST8: TOA and BRIGHTNESS TEMPERATURE converter for Landsat 8

Description

getLST8 Process Level 1 GeoTIFF Data Product of Landsat 8 and converts to REFLECTANCE TOA, RADIANCE TOA and BRIGHTNESS TEMPERATURE.

Usage

getLST8(dir, geometry)

Arguments

dir	The folder or directory where the Landsat 8 GEOTIF files are stored.
geometry	The geometry object of the geographical zone to retrieve the data from.

Details

The procedure considers as input (1) the folder where the GEOTIF data products are stored taking into account that each data product must be decompress in one folder and (2) a geometry object corresponding to the geographical zone to retrieve the data from (for instance a SpatialPolygonsDataFrame) The output of this procedure is a CSV file including the spatial data points of the extent with the raw data of the OLI (Band B8 panchromatic is not included) and TIRS bands and their corresponding reflectance and radiance TOA values for the spectral bands and, for thermal bands, their brightness temperature. The name of the CSV file is LST8_startDate_endDate. This procedure has dependences on rgdal, raster and sp R packages. The procedure does not download the data products. The data products can be downloaded from http://earthexplorer.usgs.gov/

The structure of the CSV file is the following:

x: Coordinate x of the data point in the CRS of the data product y: Coordinate y of the data point in the CRS of the data product crs_proj: CRS projection string of the data product date: Year + Day number of the year in the format YYYYddd 30_B1: OLI band 1 30_B2: OLI band 2 30_B3: OLI band 3 30_B4: OLI band 4 30_B5: OLI band 5 30_B6: OLI band 6 30_B7: OLI band 7 30_B9: OLI band 9 30_B10: TIRS band 10 30_B11: TIRS band 11 30_QA: Quality indicator of the measures 30_B1_RADIANCE: RADIANCE (TOA) for band 1 30_B1_REFLECTANCE: REFLECTANCE (TOA) for band 1 30_B2_RADIANCE: RADIANCE (TOA) for band 2 30_B2_REFLECTANCE: REFLECTANCE (TOA) for band 2 30_B3_RADIANCE: RADIANCE (TOA) for band 3 30_B3_REFLECTANCE: REFLECTANCE (TOA) for band 3 30_B4_RADIANCE: RADIANCE (TOA) for band 4 30_B4_REFLECTANCE: REFLECTANCE (TOA) for band 4 30_B5_RADIANCE: RADIANCE (TOA) for band 5 30_B5_REFLECTANCE: REFLECTANCE (TOA) for band 5 30_B6_RADIANCE: RADIANCE (TOA) for band 6 30_B6_REFLECTANCE: REFLECTANCE (TOA) for band 6 30_B7_RADIANCE: RADIANCE (TOA) for band 7 30_B7_REFLECTANCE: REFLECTANCE (TOA) for band 7 30_B9_RADIANCE: RADIANCE (TOA) for band 9 30_B9_REFLECTANCE: REFLECTANCE (TOA) for band 9 30_B10_TEMPERATURE: BRIGHTNESS TEMPERATURE (TOA) for band 11 30_B11_TEMPERATURE: BRIGHTNESS TEMPERATURE (TOA) for band 12
