Hi Arlene,

 

Thanks for your interest in MGET. I'm sorry you're seeing this problem. Based on the error message you sent, my guess is that we messed up MGET's call to ArcGIS's Near tool and did not catch the problem in testing. It looks like MGET is calling Near with the string 'NOANGLE' rather than 'NO_ANGLE', and ArcGIS is saying that it doesn't know what 'NOANGLE' means (this is probably what "Input to parameter angle not within domain" means).

 

Thanks for sending your data. I will try to run the tool using your data and let you know what I find out. If I am right, the fix should be very easy and I'll be able to send you a file to patch the tool to work properly. In the mean time, you may be able to get the tool working by adding an Angle field to your points and telling the tool to populate it. This will cause it to pass 'ANGLE' to Near, which should work. My guess is that our test code always included an Angle field, thus we never tested the tool without one and did not hit this bug in MGET. Thank you for finding it!

 

Best regards,

 

Jason

 

 

Hello, and thanks for being readily available with tech support!

 

I am excited to find this great GIS analysis tool for marine data! But having a problem with the Find Nearest Features tool. It keeps returning error messages. See error message below.

 

 I have a point file “blackrock.shp” of fish observations and a polygon file “bpi200_ridge.shp” of a single habitat type (converted from a raster of multiple habitat types). I want to measure the distance of each fish observation to this habitat feature. Seems straight forward enough. I created a field called “dist-ridge” in the fish shapefile as the field to receive the feature distance value. I tried adding a search radius of 5m and again as ‘unknown’.  Those are the only parameters I set.  I don’t know why its not working. Can’t decifer the error message. Can you help?  I attached the point shapefile and the polygon shapefile in case you want to try it.

 

Thanks! Arlene
