Yes, we have an FTP site set up for that part - the whole share size will be something like 200GB. I did try an export raster from arc and got a washed out looking tiff. Looks like the LizardTech's tools did work fine on one of the sid files. No idea why it was failing on the sample sid I had. Who knows maybe it was old or corrupt in some way. Don't look a gift horse in the mouth. I exported one so now I have a tiff that is ~30GB. I cut it up with the split raster tool which did make the tiff tiles ok - but the images in the tiles looks all washed out when done (looks the same as my esri export to tiff output)?? Why would this be happing? Other options for cutting it up into tiles?

The size is the same for the one I checked - 28.79GB.

That is uncompressed size from the properties in ArcCatalog - looks like the size on disk is a little less then a gigabyte per sid. We are doing a data share and we can only release imagery in the area of interest. We want to share GeoTiffs so that the consumer of the data can import them into a CAD package.

Hi Jake, Thanks for taking the time to reply. The sid sizes are 19.21GB and 28.79GB. I have tiff tiles for the other imagery years and after I have clipped them to the area of interest the output directory has been between 35GB and 45GB so I would image that the clipped output of the sids should be about the same if not smaller (the cell size for the year in quetion is only 2x2 vs 1x1 for the other years). The cell size of the provided sids and tiff are both the same in the tiffs and sids for these years. What would your suggestion be to demosaicing them. Maybe just an export in arc?

I have two sid files, around 25GB, that I need to process. I need in the end geoTiff tiles (1GB in size would be fine) of a sub area defined by a polygon. And I need to preserve the data quality. I have tried extract by mask, thinking that I could cut the sid down with the polygon to make the file size smaller, but it did not make an output after an hour of running even with a relatively small polygon mask. Next I looked at LizardTech's tools here: http://www.lizardtech.com/downloads/category/#tools__utilities I ran the command "mrsidgeodecode -wf -i input.sid -o output.tiff" on a 1GB sid, I downloaded for testing, and it failed. What is the best way to do this?

Is it not possible to rename a feature class that participates in topology rules? It is grayed out in ArcCatalog....

Dan thanks for taking the time to reply. I am aware of the options in the tool. That is why I said this in my original post: Please keep in mind that I would like to avoid finding the smallest straight line segment (but I guess I could). But I did not know about the Douglas–Peucker algorithm - thanks for that. Also I am 99% confident my smallest straight line segment will be smaller then max distance between vertices that I wish to target for removal. I think what I am going to try is: 1) Running the tool aggressively 2) Run the erase tool on the input and output to identify areas that got altered. 3) Fix by hand the problems

You can check out XTools pro (it has a one month trial period, I think). With that you can use convert features to points and generate points at 1m intervals on your lines. Then use them to cut your line. Then buffer your line to get polygons.

Ya, but no. It looks to me that it can change the shape of the polygon. Take a look at this screenshot from the esri docs. I was thinking that esri would have a pre-made tool for this operation. but maybe not. I think I may have to strip the FC down to lines/points and/or attack it with python.

Dan thank for the suggestion. Yes, I am aware of that tool. I have used it in the past for operations where my final output was graphical only. My concern with it is that in may alter some of the polygons shape. This is not going to be ok in this case. If I could be 100% positive that all shapes would be preserved and that all extra vertices would be removed I would run it. . . I don't know maybe the thing to do is turn them into polylines and then try to kill them and then go back to polygons.

I have a polygon FC with approximately 600,000 polygons. The problem is that polygons have extra unneeded vertices on straight line segments. In one case I counted 23 vertices where 4 would do. 19 * 600,000 = 11,400,000 extra vertices to draw; causing a lot of drag on the users of the data. What is the best way to remove the extra vertices on the straight line segments with out changing a single feature. Please keep in mind that I would like to avoid finding the smallest straight line segment (but I guess I could). Thanks for any input, Forest
