DeprecationWarning

[micbrenn]

I am new to Node.js, and have very limited knowledge of coding. That being said, I am attempting to use AGStoSHP to create a shapefile from a WMS service layer for use in ArcMap. I am under the impression that this tool will allow me to accomplish this, but please correct me if I am wrong. Let me briefly explain the process that I have gone through.

---

• I first installed Python 3.6.1 amd64 on my 64-bit windows machine. Since then, I have realized that Python 2.7 is already installed, which is the version that Arc is using. I have not yet tried installing GDAL with Python 2.7.

• I then installed GDAL 2.1.3 amd64, following the instructions here: ( https://sandbox.idre.ucla.edu/sandbox/tutorials/installing-gdal-for-windows ).

• I then installed Node.js 6.10.2 (x64) with npm. I have also tried using version 7.9.0, which didn't work either.

• After downloading the 'AGStoShapefile-master' and saving it to my Documents folder, I edited the 'services.txt', leaving only my service ( http://sig.se.gob.ar/cgi-bin/mapserv6|planosbase_puntos_caracteristicos ).

• I then opened the Node.js command prompt, navigated to the AGStoShapefile-master folder, and entered the following :

node agstoshp.js services.txt ./output/

• Here is the output that was returned:

(node:9444) DeprecationWarning: process.EventEmitter is deprecated. Use require('events') instead.

Like I said before, my knowledge is limited, but I can follow if told where to go, what to look for and what to change. Any help that anyone could provide would be extremely appreciated.

Hi micbrenn,
I got a 404 error when I went to http://sig.se.gob.ar/cgi-bin/mapserv6%7Cplanosbase_puntos_caracteristicos
Your link might be bad. Also, I think it needs to come from a rest endpoint like these: (https://services.arcgis.com/cJ9YHowT8TU7DUyn/arcgis/rest/services/About_EPA_-_EPA_Locations/FeatureServer/0)

Hi @micbrenn , @kawikakanaka is correct that that it must from an Esri REST endpoint. It supports Esri Feature Services, and Dynamic Map Services with the Query endpoint enabled. It does not support WMS. WMS returns an image of the rendered layer and does not allow access to the individual features. You can export features from a WFS, although this script does not specifically target OGC services. When working with ArcMap, you can add a WMS directly, although you cannot interact with the service like you could with a WFS or Esri Feature Service.
