Landsat 8 easier than ever!

VERSION 0.6

• Added a new function loadImageSR to load surface reflectance from
  Landsat 8 from ESPA files
• calcSR only works for L7
• calcTOAr() now estimates TOA reflectance for Landsat 8
• surfaceTemperature() uses the scene in DN and estimates the brightness
  temperature for Landsat 7 or 8. Argument thermalband is deprecated.
• Added a new example of weather station for the new Landsat 8 example
• Added a Landsa 8 scene as example dataset in raw format complete with the
  surface reflectance estimated by ESPA
• Added a new vignette describing how to use Landsat 8 data in water package

endmembers overhauled

VERSION 0.5

• Added maxit parameter to calcH to control the maximun number of iterations.
• Added an optional constrain to the selection of anchors pixels using the
  location of the weather station and a 30km buffer.
• Changed default value for Z.om.ws in calcH. (From 0.0018 to 0.03)
• Added a new parameter to calcAnchors, available for both methods: buffer.
  buffer allow to set the minimun distance between two anchor pixels of the same
  kind
• Added a new method for calcAnchors = "CITRA-MCBbc". This method chooses the
  coldest and hottest anchors pixels availables. Previous method ("CITRA-MCBr")
  chooses random pixel who meets the conditions. CITRA-MCBbc is now the default
  method for calcAnchors
• General remote sensing functions moved to a separate file
• loadImage detects when there is more than 1 image on the working folder
• Rn, G, H, LE are restricted to values > 0
• Improvements to anchors pixels selection: more releaxed hot
  temperature criterium, distance, mean of many pixels, etc
• Added two methods for land surface estimation: single channel and split windows.
  Split windows only works for Landsat 8.
• loadImage now loads thermal data also: low gain for L7 and both bands for L8
• Fixed big bug when estimating ETo with a large weather station file

L8&L7 tested

VERSION 0.3.2

• Solved errors when using non ASCII characters
• Fixes some bug who prevent using water with L8 data
• More flexibility on band names and changes to reflect the changes on USGS's
  ESPA file naming
• Improvement to plot.waterWeatherStation to plot only data from the sattelite
  overpass when the object was created using a MTL file.

First CRAN release!

VERSION 0.3

• First release to CRAN!

VERSION 0.2.9

• Added dailyET function to calc and sum hourly ET for a complete day
• Added new parameter to hourlyET and dailyET to choose between ETo or ETr
• read.WSdata doesn't require a Landsat metadata anymore. Now you can process
  weatherstation data without a landsat flyby. print method changed to reflect
  this
• function METRIC.EB now accepts many parameters for method of the included
  functions. For example, you can set with method you choose for LAI estimation
• We're approaching CRAN launch date. Changed version numbering to reflect this.
  First CRAN version will be 0.3

VERSION 0.0.2.4

• Added function to prepare data from Weather Station and calc weather
  conditions at satellite flyby.
• Added function to calculate Surface Energy Balance using METRIC

VERSION 0.0.2.3

• Rename sensibleHeatFlux() to sensibleHeatFlux_old()
• Remove sensibleHeatFlux.CITRA()
• Split sensibleHeatFlux in 2 new functions:
  • calcAnchors() for anchors points
  • calcH() for the iterative process to calculate H and dT
• Added function to estimate Net Radiation

Beta 2.3

• Rename sensibleHEatFlux() to sensibleHEatFlux_old()
• Remove sensibleHEatFlux.CITRA()
• Split sensibleHeatFlux in 2 new functions:
  • calcAnchors() for anchors points
  • sensibleHeatFlux() for the iterative process to calculate H and dT
• Added function to estimate Net Radiation

Beta1

All features complete. Now should work with Landsat 7 or Landsat 8. Needs meta-functions. Needs documentation.

alpha4

Now works from start to G. Takes 4.84 minutes using ON aoi. Still need to solve iteractive process.

alpha

Start preparing the package to distribute. All files created, need more documentation, and the iteractive functions doesn't really works... but I have a tar.gz So I Got That Goin For Me Which Is Nice.
