Hello,
I am having a hard time figuring out why I receive a 010005: unable to allocate memory error when running the optimal path as line tool. My inputs for the tool include a back direction and distance raster derived from the distance accumulation tool as well as the source destination, which are points in a single feature class. The rasters were created by using a mosaicked DEM as the surface raster and inputting a table representing Tobler's off-path hiking function as a cost relative to vertical movement in the distance accumulation tool. I have successfully generated several LCP's (upwards of 8 during a single run), however after so long, the optimal path as line tool stops working. When operating properly, the tool takes less than a minute to run. Recently, it takes about 20 minutes to trace cells and ultimately fail when I receive the unable to allocate memory error. When troubleshooting the error, I find this:
Description:
The computer does not have enough available memory to perform the operation.
Solution:
Close down other unneeded applications to free up system memory. You can also increase the virtual memory allocation of your system. Another option is to split the input dataset into smaller sections and merge the results. Also try using a larger cell size.
I have reduced datasets, moved projects to a different computer, restarted the project and I do not understand why I keep receiving the error (even when trying to run a single LCP) when I did not experience any issues when beginning my project. If anyone has any insight into this and how to resolve it, it would be very helpful and greatly appreciated.
Thank you,
Talissa
