这个方法会损坏原始栅格的内容 操作思路就是使用栅格计算器的SetNull函数将指定图层的制定数值设定为Nodata,也就是Null,执行之后,所有的 0 值变成了 Nodata,彻底去了黑边。 SetNull(“RasterLayer” == 0 , “RasterLayer” ) 1. 3.2 不显示无效值(0,0,0)(255,255,255) 右键图层,点击...
When Nodata is present, the output of QGIS is different, it seems to preserve more pixels around nodata values. QGIS vs GeoServer with bilinear: And the same with nearest: Interesting.. QGIS seems to be "filling holes" when using bilinear......
首先就是下图中上方的红色方框,选择我们需要设置的栅格文件即可。随后就是下图中下方的红色方框,我们首先在“Bands for NoData Value”选项中,找到我们需要配置的波段;其次,在“NoData Value”选项中,输入0即可。如果我们是需要对其他指定的数值设置,就在这里填写这一指定的数值即可。 设置完毕后,可以在栅格...

The correlation matrix sets the row and column corresponding to a constant value dataframe column to NaN. A workaround could be to remove the NaN columns and rows, as suggested by @TrentonMcKinney, for example with corr = corr.dropna(how='all', axis=1).dropna(how='all', a...
