Partial output from MakeStreams #43

Hi Adam, I loaded a 5.75 GB GeoTIFF into TAK and the .mat file was output in a reasonable amount of time, but when I did not see the other files for GIS usage, I let it run a few more days. It never generated the other files. I tried running the same DEM through the compiled version (input as follows: TAK MakeStreams D:\SinkholePlainGIS\20200505 CentralKentuckyMerged.tif 1e6 test) and received the error, "Too many input arguments." Also wanted to say, I love the look of the new GUI! Way easier than the compiled version. My only recommendation would be to add a progress bar or something similar so people can gauge how long they might expect it to be processing. Thanks, Rachel

Hi Rachel,

Sorry, just seeing this now. That is a pretty big TIFF and it might have just maxed out the active memory. One issue with the GUI is that has more overhead, so it eats into what can be processed. Was the .mat file large? (i.e. was it empty?) At the end of the day, the work around for really big files is usually to chop them up if possible.

RE a progress bar, this is actually a lot more challenging than it seems like it should be unfortunately.
