Grid with parameters of the surface drainage...
The shapefile is a polygon dataset of rectangular (square) grid where each grid cell is exactly overlaying a pixel of the LANDSAT 8 imagery as downloaded from the Google Earth Engine. Each cell contains information about properties of 2013 and 2022 DEMs and stream maps as well as derived data such as differences in the parameters between the years and resutls of analysis with Local Indicator of Spatial Association (LISA). The files have progressively more complete tables, with the final version (univ_tongue_grid_streamDataWithMorans.shp) having the following:
Fields: POLY_ID, id - ID number of the cell, Sedim. 202 - sediment abundance in 2022 Sedim. 201 - sediment abundance in 2013 Slope 2013 - mean slope of the surface derived from a 2013 DEM KBRI 2013 - value of the KBRI index derived from a LANDSAT 8 image KBRI 2022 - value of the KBRI index derived from a LANDSAT 8 image Slope 2022 - mean slope of the surface deriveed from a 2022 DEM dem22mean - mean elevation derived from a 2022 DEM dem22stdev - standard deviation of elevation derived from a 2022 DEM dem13mean - mean elevation derived from a 2013 DEM dem13stdev - standard deviation of elevation derived from a 2013 DEM strDen2013 - stream density derived from the 2013 stream map (m/m2) avgOrd2013 - mean order of streams within the cell derived from the 2013 stream map medOrd2013 - median order of stream derived from the 2013 stream map minOrd2013 - minimum of the order of streams within the cell derived from the 2013 stream map maxOrd2013 - maximum of the order of streams within the cell derived from the 2013 stream map stdOrd2013 - standard deviation of the order of streams within the cell derived from the 2013 stream map strDen2022 - stream density derived from the 2022 stream map (m/m2) avgOrd2022 - mean order of streams within the cell derived from the 2022 stream map medOrd2022 - median order of stream derived from the 2022 stream map minOrd2022 - minimum of the order of streams within the cell derived from the 2022 stream map maxOrd2022 - maximum of the order of streams within the cell derived from the 2022 stream map stdOrd2022 - standard deviation of the order of streams within the cell derived from the 2022 stream map strDenDiff - difference in density of streams between 2022 and 2013 debDiff - difference in debris abundance between 2022 and 2013 kbriDiff - difference in KBRI between 2022 and 2013 sloDiff - difference in slope between 2022 and 2013 avgOrdDiff - difference in mean stream order between 2022 and 2013 LISA_I_den - Moran's LISA value based on the stream density difference map LISA_CL_de - Class of Moran's LISA analysis based on the stream density difference map LISA_P_den - p-value for determination of statistical significance of the LISA_I value for the stream density difference map LISA_I_ord - Moran's LISA value based on the mean stream order difference map LISA_CL_or - Class of Moran's LISA analysis based on the mean stream order difference map LISA_P_ord - p-value for determination of statistical significance of the LISA_I value for the mean stream order difference map
