Point density - Errors

LorenFreslaud

Hello Esri Community,

I would like to do a Density population map for my thesis but I had 2 errors when I tried :
1. ERROR 01038 Syntax error at or near symbol NEW-LINE
I precised that DDminimum does come from a polygone but convex hull (Minimum geometry boundary tool).

2. ERROR 010267 Syntax error in parsing grid expression
I did the Environment setting (attached). Environments > Raster analysis

Looking forward to hearing your feedbacks !
Thank you,

Loren

ERROR near symbol NEW-LINE + parsing grid expression

Is anybody could help please ?

The tool inputs would be more useful.

It looks like you may have a file path that has a space, international characters, or punctuation or the filename itself.

LorenFreslaud

Dear Dan,

Thanks for replying. I started to desperate!

I removed the space from output raster destination, but another error appeared : "unable to open the mask raster ".

"Home range" (previsously called DDminimum) is a file from Minimum geometry boundary tool.

ERROR near symbol NEW-LINE + open mask raster

Do you have an idea ?

c:\Users\Lo'\Documents\MSc WCM\Msc….

punctuation after Lo and space after MSc can't see the rest.

Try moving everything out of the Users folder... maybe C:\GIS

Thank you Dan and Xander for answering !

I changed my folder emplacement and switch off the tick in Background processing

However the error "parsing grid expression" appeared ?

ERROR parsing grid expression

We will success soon I am sure !

Can you show the actual tool dialog input Loren, not where you searched for Point Density.

Point Density—Help | ArcGIS Desktop

ie. the input file, the population field and any other optional parameters.

You do have the Spatial Analyst extension enabled as well?

LorenFreslaud

I have the Spatial analyst extension.

Point density toolbox

From Point density toolbox :

Environment - Raster analysis - Mask

You aren't working with projected data.

The cell size and circle radius units suggest this.

I would use projected data for the inputs.

As for the mask, for now, drop the mask to see if it works without the mask.

Simply use Select by Attributes to select the points that fall within the convex hull and save those as a new (projected) point file.

As for the output... make it a *.tif file avoid an esri grid... simply add tif to the end of the file name once you have chosen your saving location.

I think it is a combination of not using projected data for the inputs and perhaps the mask

And this little snip seems to show that the data points are all on the home range boundary.

Dear All,

It's worked ! any advice to modify my rectangle Point Density (DDdensity) like my DD poly (in transparent) ?
When I selected Mask > DDpoly it repeat th same error :
ERROR 01038 Syntax error at or near symbol NEW-LINE
ERROR 010267 Syntax error in parsing grid expression

Thank you for your help and support !
