RE: [MI-L] Shifting vectors over image

[David Reid]

Title: Message

This happens too in "draw" programs, Corel Draw for instance.  If zoomed in too close, the raster will appear to shift around as I digitize.   I suspect it to be the dimensional size of the raster, and or its resolution. My high resolution DOQQ's don't appear to jump around, however, I have a single ortho that covers my entire county, 8-10meter resolution, 10's of thousands of pixels wide (image width) and if I'm zoomed in too far with it, it will dance the Jitter Bugg when I digitize or move a node.   Dave   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ryan Morgan Sent: Monday, April 03, 2006 10:48 AM To: Robert Crossley; mapinfo-l@lists.directionsmag.com Cc: Mark Beech Subject: RE: [MI-L] Shifting vectors over image Hi Robert, I doubt the vectors are moving, don’t ignore the possibility the imagery is the layer that is shifting about.  This is especially likely if there are two or more raster layers open at the same time.   Hope this helps,   Ryan Morgan Aerials Express   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Crossley Sent: Thursday, March 30, 2006 8:42 PM To: mapinfo-l@lists.directionsmag.com Cc: Mark Beech Subject: [MI-L] Shifting vectors over image   A colleague rang today with an issue about Mapinfo moving its vector layers as he zoomed in or out.  The vectors were overlayed over a very high resolution image, and moved as he used the mouse wheel to zoom out or in. One click out and the vectors were displaced 20m, another click and they were right again. Another user was using the same image reprojected to another projection to match their vector data, and he had the same issue. Any suggestions on a cause or even better on a solution?
