The Topodata digital elevation model (DEM) is the best DEM available for digital soil mapping (DSM) in Brazil. However, it is not ready to use. We show that the kriging interpolator used to downscale the SRTM DEM from 3 arc-seconds to 1 arc-second spatial resolution increased the double oblique striping (15º and 60º) so common to SRTM DEMs. This is because kriging is quite sensitive to outliers. Besides, the Gaussian model of spatial covariance used in the downscaling enhanced the sensitivity of kriging to outliers, thus enhancing the striping. 2D Fast Fourier Transform can be used to identify whether a destriping procedure need to be employed. The bilinear or cubic resampling methods should be used to warp Topodata DEMs because they are insensitive to the double oblique striping. |

Abstract: The in vivo production of embryos is used to accelerate the multiplication of the herds, but the efficiency of this biotechnology is widely variable in small ruminants. The variability of the superovulatory responses and the production of viable embryos has been related to several factors, including the dose of gonadotrophin used in the hormonal treatment of superovulation, and the occurrence of prematurely regressing corpora lutea. In this context, the present study was performed to evaluate the effect of different doses of pFSH on the superovulatory response and vascularization percentage of the corpora lutea (CLs) formed. In conclusion, the vascularization percentage of the corpora lutea during the initial luteal phase is affected by the dose of pFSH used in the superovulatory treatment of sheep. Despite this, the superovulatory response does not differ between doses of pFSH. Further studies are needed to determine the relationship between the vascularization percentage of the corpora lutea and its functionality.
