A question for those who might answer or offer advice for this problem of mine. First I should say that I enjoy this program more and more, great work and support. Now my questions:
My height field was generated from 3arc second STRM data and our intended coverage area encapsulates about 720km. I have to cram that onto a 131072 plane. 3arc second is about 90meter resolution so I have to upsample by a significant value (16). The process I have tried using is to resize my imported HF on export from the 8192px* to 131072 as a HF mosaic. Ideally I need tiles themselves of 8193 * 8193 but I don't get very far with a tile that size so I left it at 512*. Is this the correct way?
I would also like to use L3DT to generate an attribute map which I am inturn using for the game engines texture correlation and placement, and would like to do that with a HF chunk of 8193px. So, it would be great to keep thing in that size unless I could solve my next problem. Presently, I have been upsampling one at a time after cutting the map up without resizing, and while this works fine, I am running into slight differences in my elevations at the seams. This certainly is my error however I have tried border duplication, horizontal scale is the same so it must be my vertical scale that is at fault? I'm using a .png with this pS plugin http://www.fnordware.com/superpng/
and assume I am just letting it span the grayscale by leaving it default?
Any help would be appreciated.
