nasa-develop / metric Goto Github PK

This came up in issue #3 by @lsapia, but deserves a separate issue thread.

Somehow the Con function from the arcpy.sa module is not importing properly.

Dear Jeff Ely,

I have been conducting studies with evapotranspiration of crops and recently started studying the metric.

Due to little experience in programming in python I have not been able to program metric in ArcGIS.

I was able to execute your tool, "metric configure", however I can not execute "metric run" because I can not find the file valid for execution.

How can I proceed? I am running ArcGIS 10.6.

Thank you!

#Hi Jwely,

i found an error in the code. If you look at line 628 in the function_bank.py (see below) the k "von Karman's constant" should be 0.41, instead of .041...right?

Cheers,
Luca

I am not able to create a valid configuration file using METRIC_configure.
Many annoying issues occur (.ovr and .xml are required, shapefile codepage etc.).
The bad point is that Landsat band 2 seems to be skipped (wrong enumeration?)...
Do you have a working config file, just to check its format and/or try a manual config?

In Arcmap 10.1 I load the .pyt toolbox, but the two scripts don't run. The error message is blunt ("Unable to execute the selected tool", and that's all...).
From IDLE, the scripts run with no errors - obviously, also no output.

Sir,
how is possible to add this tool in ARC GIS i tried to add it as py script in tool box it didn't work?
regards

Hi
I cannot run METRIC "metric_tbx.pyt" , Error is:

"Traceback (most recent call last):
File "", line 249, in execute
File "D:\METRIC-master\METRIC\prepare_metric_env.py", line 115, in prepare_metric_env
raise Exception("input workspace must be a directory that does not already exist! one will be created here!")
Exception: input workspace must be a directory that does not already exist! one will be created here!

Failed to execute (METRIC_configure)."

I saw coment in "#5" and use "https://github.com/NASA-DEVELOP/METRIC/archive/patch-ovr-issue.zip" file but I faced by error message again, How do I Solve It?
best regards

Hi all,
i'm an italian engineer. I have studied the METRIC model for the estimation of actual evapotranspiration from satellite images.
I found on github your model (NASA-DEVELOP/METRIC) and i'm trying to make it work on Northern Italy, but it doesn't work. I can't understand why...
Can you help me?
I'm attaching the input dialog box and error message printed in Executing METRIC_configure in ArcGIS 10.2.2:

Thank you for your attention,
Luca

Dear all,
I a student working on the hydrological process, I have stepped to the "METRIC_run" in ArcMap of METRIC model (’METRIC-patch-ovr-issue‘ package), but with the file 'config.txt' from the last step output, the problems come as follow, could anyone help me with them? I will be appreciated, cuz it now the only method I find to finish my project.
