After searching around for similar situations, I fixed the issue by' Reordering the bands to RGBN (They were BGRN) with gdal translate Converting the images from Uint16 to Byte with gdal_translate Lastly, I warped them using gdalwarp using the -tr and -tap options. The solution at step 3 I found at: Holes between imagery tiles projected using gdalwarp
You won't have any luck finding a satellite that provides data from the ultra violet (UV) portion of the electromagnetic spectrum. The reason is that the wavelength of UV energy is so short that most of it gets absorbed or scattered by the atmosphere, or tiny particles in the atmosphere before it even gets to the Earth (from the sun) let alone back up to any ...

You can do this as follows: Views in the menu and then Create New View. Load your images in different views.
There is no specific GIS software for doing this: most will handle the RGB image and the Lidar data. Basically, NDVI is (NIR - RED)/(NIR + RED). Most of the time, aerial Lidar gives you the NIR value (to be checked in metadata) and the first band of your RGB image gives you the RED value. Just make sure that your data are calibrated to reflectance (or, if ...
You cannot avoid changes to the online basemap layer because you do not have control over it. The imagery could be updated at any time - all of it, or a single tile. The imagery is loaded each time you connect, so no, it does not 'freeze' at the date you added it to your map. The only way you can ensure you will be using consistent or specifically dated ...
