Export map mosaice error, erroneous image extents #145

Closed RRLash closed 11 years ago

RRLash commented 11 years ago

I'm a new MapKnitter users, and am trying to make a mosaic of historic aerial photos covering midtown Atlanta. I've created this map- http://mapknitter.org/map/view/1949-midtownairphotos, and it appear to have an erroneous artifact created during the export map mosaicing process, which I can figure out to correct. The attached photos show roughly the images which are being omitted in the final map output. mapknitter_mosaicerror

I've searched the GIT/MapKnitter/Issues page, and done some quick googling, but haven't seen any discussion of people encountering similar issues. The links to the original images are on my map project page. The only further image processing I have done is to open the original JPGs in Photoshop CS6 to crop the images, and do basic contrast stretching enhancements. I then resaved the photos as JPGs from Photoshop, and uploaded these new photos to MapKnitter. I would like to add additional images to the mosaic, but will wait to learn more about how to resolve this issue. Thanks!

Greetings, this is a known issue: https://github.com/jywarren/mapknitter/issues/127

Perhaps you can try producing 2-3 separate geotiffs from this scene instead of 1? Maybe we can trace this issue back to either map extent or some other cause.
