Author Topic: Large utm file (Read 5103 times)

Oak · « **on:** December 20, 2003, 12:25:24 PM »

I have a set of large UTM files, between 3 and 15 megs. It would be extremely neat to be able to use them on Topo fusion. I am able to display them fine, but program crashes if I try to move them. I realize they are exesive in size but is there an easy solution memory or such? the program crashes after I draw the box around the object and before it highlights the points.

Thanks
Oak

I think there might currently be a hard limit on the number of possible selected points, I will check into it. Â Thanks for reminding us about it (it should not be limited like this, and it certainly shouldn't crash).

Looks like the limit is 100,000 selected points! We'll make it dynamic for either the next beta or full release (probably beta).

No one could possibily select more than that right? ':p'

This is one for the brown's list. Thanks for pushing the edge of TF.

I am a bit curious why you want to move all these points? Are you avoiding a reprojection or something (just doing it by hand?)..

I have map files that unfortunately do not have geo refernece data, so I re-write them to a nearby location, then slide them to the exact location. I am really excited about there use. The file I have made is a txt utm file it has many many many
begin line
blaha blah blah
endline
begin line
blaha blah blah
endline
begin line
blaha blah blah
endline
Sometimes with only one or 2 lines in each.

Very awsome program you have made

Are your files generated by some version of TopoUSA? If you export to "UTM text file" you get a similar structure (begin line end line, etc).

If so, they should read in with TopoFusion no problem, just make sure they have the txt extension. Good luck.
