Pinchpoint Mapper error about

[Shin Kanno]

Hi

After running "build network and map linkages" successfully for my data, I tried "Pinch Point Mapper" , but it gave me this errors on focal node raster.

When I carry out with demo datas, there are no problems.

Using circuitscape and linkage mapper's version are latest.

Thank you in advance for a pleasant response

Best regards

NOTE: ArcGIS errors are more likely when writing to remote drives or deep file structures. We recommend shallow project directories on local drives, like C:\puma. Errors may also result from conflicts with anti-virus software (known problems with AVG). We have also seen conflicts when writing to synchronized folders like DROPBOX.

Note also that Linkage Mapper tools often work best when run from ArcCatalog instead of ArcMap.

I am not sure why that is failing.  Does it also fail if you uncheck "calculate adjacent pairs..." ?

It looks like it is having a problem with your resistance surface.  Maybe convert any null values to a number?

Anyone have any ideas?

Thank you for replying and your advices.

 I carried out Pinchpoint Mapper again without checking   "calculate adjacent pairs.

Pinchpoint Mapper seemed to output the results with no issue for my data, but that output was empty...

 As you said, my resistance data  is probably having some  unsuitable values like no data.

I  try to convert again for my resistance data.

If you come up with any good solutions, please let me know.

Hello Shin,

1) please make sure there are no cells of "NoData" in the resistance surface that are within the extent of the mapped resistance surface.  It is OK if they surround the surface at the edges of the extent.

2) If that still does not work, please send the log text files for the successful Map Linakges and Buld Network model run, as well as the failed pinchpoint mapper run.

Thank you,

JOhn
