Description

The data.txt file is a tab-separated ascii file. The file contains all raw data used in statistical analyses of Greater Rheas habitat models.

The spatial resolution chosen for the analysis was based on the 20 % of Greater Rhea home range. Sampling area is equivalent to 1.5 × 1.5 km moving window, including 2,500 Landsat pixels. The mean value of all pixels within the window was used in each variable.

Column definitions:

1 = ID, Data identification

2 to 7 = Correlation index (CR, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively)

8 to 13 = Variance index (second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively)

14 to 19 = Mean index (MN, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively)

20 to 25 = homogeneity index (HG, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

26 to 31 = entropy index (ENT, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

32 to 37 = dissimilarity index (DISS, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

38 to 43 = contrast index (CONT, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

44 to 49 = second moment index (SECM, second order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

50 to 55 = variance index (VR, first order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

56 to 61 = mean index (MN, first order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

62 to 67 = entropy index (entro, first order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

68 to 73 = skewness index (skw, first order texture variable corresponding to Landsat band 1,2,3,4,5, and 7 respectively).

74 = proportion of bare soil

75 = proportion of grassland

76 = proportion of crops

77 = proportion of forest

78 = proportion of alfalfa

79 = NDVI

80 = Coefficient of variation of NDVI (%)

81 = Distance to houses (km)

82 = Distance to roads (km)

83 = Distance to water (km)

84 = Greater rhea group size

85 = location of each group; UTM_X (m)

86 = location of each group; UTM_Y (m)
