In this study, the residual map was obtained after an upward continuation of the TMI-RTE grids at 4 km.
The upward continuation processing of the residual map was obtained at various altitudes.
Figure 5 represents the area residual map of the TMI-RTE upward continued at 4 km.
The HGM map of the study area has been realized by using the residual map of the TMI-RTE upward continued at 4 km (Figure 6).
Each residual map is composed of model residuals from eight different land-cover-specific statistical models predicting the same building type.
Residual maps indicate that both model predictions deviate from parcel counts, with overestimations for one-family residences and underestimations for multiunit buildings.
The residual maps in Figures 6e and f illustrate that multiunit buildings tend to be systematically underestimated in target zones of higher building counts and overestimated where counts are low.
We hypothesised that plant P uptake from fluid MAP fertiliser would not be restricted by a soil moisture deficit and also that some of the residual MAP would be available to subsequent crops.
The P fertiliser treatments were: (1) zero P fertiliser applied in Expt 2 or 3; (2) zero P fertiliser applied in Expt 2 and 8 kg P/ha of MAP banded at 40 mm in Expt 3; (3) residual MAP banded at 40 mm in Expt 2 and zero P fertiliser applied in Expt 3; (4) residual MAP banded at 80 mm in Expt 2 and zero P fertiliser applied in Expt 3; (5) residual MAP banded at 40 mm in Expt 2 and 8 kg P/ha of MAP banded at 40 mm before planting in Expt 3.
Uptake was also similar from soil cores with residual MAP fertiliser placed at 80 mm, growing under wet soil moisture conditions.
The resulting residual map will be named the local anomaly map.
With two successive approaches, firstly over the residual map (data minus regional component) and, secondly, over the residual minus previous estimated signal, the successive correlation analysis of the data gave us a distribution of empirical covariances, which were adjusted by means of suitable analytical covariance functions (Fig.
