formatSRdata: formatSRdata

In RSAlgaeR: Builds Empirical Remote Sensing Models of Water Quality Variables and Analyzes Long-Term Trends

Description

Format surface reflectance data

Usage

formatSRdata(data, value, imagerydate, samplingdate = "", location, datatype,
  qaband, qa_accept)

Arguments

data	dataframe of surface reflectance data. Designed to work with reflectance values for bands from Landsat surface reflectance products (Blue, Red, Green, NIR, SWIR1, SWIR2, QA Band) at specific point locations
value	string, name of column with water quality parameter values
imagerydate	string, name of column for imagery dates (must be date format)
samplingdate	string, name of column for sampling dates (only required if dataset is used for calibration, must be date format)
location	string, name of column for location identifier
datatype	string, "Calibration" or "Estimated"
qaband	string, name of column for QA (such as a cloudmask) rating
qa_accept	vector, QA classes which are acceptable

Value

dataframe with formatted data

Examples

data(srdata)
formattedsrdata <- formatSRdata(data=srdata,value="FieldValue",imagerydate="ImageDate",
samplingdate="SamplingDate",location="StationID",
datatype="Calibration",qaband="CloudMask",qa_accept=c(0,1))
