I am working in Inkscape v1.0.1 on a macOS Catalina. I have a PDF image (Input.pdf) and a PNG image that I want to import in Inkscape, add text to, and then export as a single PDF image (Output.pdf).
When I import Input.pdf into Inkscape, thin horizontal white lines appear across the map, and they seem to appear/disappear depending on how much you zoom in (see Project.svg). If I export from Inkscape as a PNG, I do not see the white lines (Output.png), but I need a PDF. When I export the completed project as a PDF and then open Output.pdf in Mac Preview, I still see the horizontal white lines, and they still appear/disappear and move around depending on how much you zoom in. If I open Output.pdf in Adobe Reader, I do not see the white lines. I need to be able to submit this as a PDF as part of a manuscript upload, so I cannot control how the people on the receiving end open the PDF, and therefore need to do everything in my power to make sure it looks right.
I need this file to be in PDF format that is viewable on-screen (not just in print). I have searched in this forum and in google, and I cannot find anyone talking about this exact problem. The closest problem I can find is talking about fixing white gaps between objects, but that's not my problem.
I emailed the Output.pdf to several other people - some of them see the white lines, and others do not, and this does not seem to relate to OS.
Has anyone experienced this problem before? I can't imagine I'm the first to encounter this issue, but I cannot seem to find any existing posts asking for help related to this. Is there something different I need to do when importing Input.pdf into Inkscape? Is there something different I can when exporting the final Output.pdf?
The artifact is a unfortunate result of the satellite image background being a series of tiled bitmap images, and using a PDF as source material. (PDF is intended to be a release/distribution format.)
That said, the tiled images can be reproduced in Inkscape as a single image and the tiles can be discarded. It takes a bit of fiddly work, but if the result is acceptable, I'll outline the process.
That product looks good to me! Yes, if you wouldn't mind outlining what you did so I can repeat those steps in the future, that would be great. Thanks!
The command File → Clean up document removes unused definitions from the <defs> section of the SVG file. This includes things like unused gradients, patterns, markers, and filters.

Thanks in advance for any suggestions.

Examine the attached pdf and chime back.

To eliminate the white lines, I used these steps:
Open Project.svg
Open Menu: Object>Objects (docked list on right)
Save the SVG for editing and save a COPY as PDF for release.
(Images are in reverse order.)
NB in the Preferences dialog, bitmap quality is set to 300, for good print quality.
Thank you! I was able to recreate the process. Last question out of curiosity - what does "clean up document" do?
