Stitching of satellite images

Not a direct map request, rather looking for some assistance. From USGS EarthExplorer, I downloaded some early satellite images (the low-resolution preview version, high resolution is not available for free). These image are not georeferenced and show only very small areas, so for georeferenciation, the images need to be stitched first. Have not done that before, so the question, is there free software for that purpose?--Antemister (talk) 19:56, 29 February 2024 (UTC)

Antemister, what product are you using from the EarthExplorer? I didn't even know there were things you could purchase from the site-- are you sure it isn't a free download? A georeferenced raster could very easily be merged in QGIS or similar. – Isochrone (talk) 21:00, 29 February 2024 (UTC)

It is about the "declassified data", it contain images from the early US reconnaissance satellites in the 1968s. The images are scanned, but only in low resolution and not properly georeferenced. What I want to do is drawing the shorelines of Aral Sea in 1968, for that I have to download a few dozens of these narrow stripes and then stitch them before georefencing.--Antemister (talk) 21:28, 29 February 2024 (UTC)

Can we add Albania and Kosovo on this map since the verore is also used there?

This map is really useful in illustrating why the U.S. state of Virginia was split in two during the American Civil War, but it's difficult to read, and a colorful SVG would be better! We wouldn't need all the numbers or the names on the counties, just the map with colors shaded in a similar way. Thanks! -- Patrick Neil, _oѺ^∞/Talk 19:04, 2 March 2024 (UTC)

Location of the Karnat dynasty as per the Schwartzberg Atlas of South Asia

Article(s)

Karnat dynasty

Request

Please create a map showing the rough location of the Karnat dynasty as per the Historical Atlas of South Asia by Joseph Schwartzberg. For copyright reasons, I can’t use a screenshot from the map itself so if you could make an equivalent showing the location of the Karnatas, that would be appreciated.

If you zoom in, the Karnats are based on the India/Nepal border.
