• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Where can I get a get a better satellite image for an aerial image

I cannot find a hires satellite image of a particular area which doesn't have a huge shadow across the area I want (caused by tall buildings).
I am using Google Earth and have tried 'historical data' unsuccessfully (usually much lower resolution images).
I would be great if Google Earth had satellite photos taken at different times of the day.
I have googled for satellite images but could not find any hires images.
Does anyone know of where I might try?

Not only shadows, but aerials have perspective issues. Not every structure is top-down, but slightly from a side angle. And the side angles are different as the camera moves to the next snap.
 
Thanks Dick. Yes that can be an issue but (usually) I only want satellite imagery of ground level or not much above ground level.
 
You'll need to edit the aerial in a paint program to get rid of shadows.
 
The latest Google Earth imagery is likely to be some of the best available, and would as Dick states, requires graphics edits to remove / minimize shadows.

The default / current Bing imagery might be regarded as "second best" available.

To fix "perspective" issues, Nanaimo now has LiDAR-derived 3D building models; if their display is enabled in the Google Earth map viewer workspace, top-down screenshots may be captured in Google Earth that appear "on-Nadir", thus showing more of the roofs- and less of the "sides"- of the buildings.

That process could, if one composited multiple 3D tiles, 'cover up' much of the offset building images to reduce overall imagery graphics workload.

That is what I do using Paint Shop Pro (especially using the clone brush) but it is difficult and very laborious. I also considered adding (taxi) 'paths' but didn't think I could get the two color effect.
I just hoped that there were other satellite images of the area taken around midday (in late June - summer soltice) or in the morning when the shadow would be on the other side :rolleyes:.

Not sure if that would help as I only want the ground imagery (the two toned pathway). Maybe add paths then 'overlay' them with a texture for the two color effect - not sure if that is possible but would keep me busy these cold and windy winter days here.

I would use aprons. Base layer one color and another layer over it for the red. Or model it in Blender.
 
Thanks Dick. That is a great suggestion which I would have tried except for the following -
I decided today to try 3d satellite imagery of a large area including buildings and the pathway which seems to work well even though the satellite imagery is fairly low res. That has solved another problem I listed elsewhere regarding strange behavior to the elevation of separate scenery objects when terraforming polygons are used as the 3d satellite imagery creates the changes of ground elevation and so the terraforming polygons are not required.
