J. Wallace Posted September 9, 2020 Share Posted September 9, 2020 Hello everyone I have a question that I haven't been able to answer as of yet. I just imported some shapefile contour lines from a drone survey and the 185 acre site model creation was quick and painless...yeah! The high resolution Tiff file (overhead view of site) is about 1.6 GB and will not import into VW or any other software I have which is not a total surprise. The drone operator has asked me what is the max size I can handle??? No idea...I do see that I've used images that are 200+ mb but I'm not sure of VW limitations. Any thoughts would be appreciated. Thanks 😀 Quote Link to comment
Claes Lundstrom Posted September 10, 2020 Share Posted September 10, 2020 I regularly and very frequently import huge image files, 200 - 500 megapixels, with no problem whatsoever. There must be something else going wrong than VW's basic capabilities. One thing to check though may be if the image exceeds 30,000 pixels in any given direction. Not sure where VW stands on this thing, but many programs have such a limitation, even older versions of Photoshop. Quote Link to comment
Administrator JuanP Posted September 10, 2020 Administrator Share Posted September 10, 2020 @J. Wallace I was not aware of any file limitation importing Tiff files. Any chance that you can share the file? I couldn't find a Tiff file close to 1GB to test. If so, you can upload it using this LINK thanks, 1 Quote Link to comment
Jeff Prince Posted September 10, 2020 Share Posted September 10, 2020 @J. Wallace Good question, I don’t know the answer. However, regardless of any limit within Vectorworks, it’s best to break those large images up into tiles so you can turn them off by area when they are not needed. I also prepared a low resolution version of my aerials to use when quality requirements aren’t as high. 4 Quote Link to comment
J. Wallace Posted September 10, 2020 Author Share Posted September 10, 2020 Thanks @JuanP I have am uploading this know, it might take a bit of time. Thanks for looking at this. @jeff prince thanks for the feedback, using tiles is a great idea and I have these as part of the deliverable s I received. I'll give that a try. 1 Quote Link to comment

The link is working maybe the connection timed out due to the size of the upload and the upload speed. I will reach out directly. Quote Link to comment
Art V Posted September 19, 2020 Share Posted September 19, 2020 (edited) @J. Wallaceas @jeff prince already mentioned, splitting the images in tiles is they way to go. If the Tiff image is georeferenced, which I assume it is, it best to use a GIS program (QGIS, GlobalMapper, ArcGIS etc). to keep the georeferencing intact. That way you can seamlessly import the tiles and they should align properly without having to manually align them. When creating the tiles it is best to save them as georefenced jpg files instead of georeferenced tiff files. Even when there is no size limit for TIFF, importing jpg files is quicker than importing TIFF files because VW does not have to compress them internally as jpg/png . At least that is my experience. Because JPG files usually compress tiff files by a factor of 10, I would aim for tiles of approx. 400 megabytes uncompressed maximum, which creates jpg files of approx. 40 megabytes that should import without issues. I've been able to import 20+ GB georeferenced TIFF files that way into VW without problems. (Though you do end up with a big pile of tiles 😁) Edited September 19, 2020 by Art V Quote Link to comment
