Map Processing

I flew a creek and had it processed and the download-able maps were incomplete. I realize that the lack of overlap due to the trees is causing portions of the maps not to be processed. But the preview image that is overlayed on google maps shows the whole area. I am not looked for 3d data of any really accurate data. I just need to see the creek fully. Is there any way to get the preview(whole) flight picture?

You can get the Flat Map Patched section by appending -patch into the filename. 

For example if the file name was ...e341-90834.tif you would copy the URL and change it to ...e341-90834-patch.tif

That patch is merged with what you get from the photogrammetry and is what is used to generate the icon.

Thanks for the response. Pardon my ignorance, but is this different than the ******.tif-patch (flat map geo tiff) in the files that i can already download? I see the .tif patch in there but is is still an incomplete image and does not match the preview or google maps overlay. If this is different, im not quite grasping how changing the url would work.

 

thanks

So I downloaded the .tif file and saved it with -patch behind the file name. That did not seem to work?

The -patch has to come before the .tif as noted above. I forgot we put a link in there to it now. That is new. 

You have to combine the GeoTiff and the patch to get the whole image. You can find instructions on how to do that here:

But just for viewing purposes importing the two rasters (GIS speak for opening two image files) would be enough.
