arcpy support for JSON strings

EricEagle — Fri, 20 Jan 2023 19:32:24 GMT

As far as I'm aware the arcpy.JSONToFeatures_conversion utility only takes a flat file, e.g., your-json-file.json sitting in a directory.

I would like to suggest that this utility provide support for strings embedded right in one's script instead of having to summon os and mess with paths. So basically instead of:

import arcpy

import os

file = your_file.json

path = r"C:\Temp"

json_file = os.path.join(path, file)

arcpy.JSONToFeatures(json_fileaaaaahhhhh just makes my head hurt writing it)

it should be like this:

import arcpy

json = { bunch of json/geojson }

arcpy.JSONToFeatures(json, output)

Currently, the second approach throws a series of GP errors as it does not appear the tool is set up to handle strings but only files.

I just want to add that because of this limitation, I am doing the following extremely dubious workflow -

I am doing an automatic "project this raster to the correct UTM zone" script that is meant to be a part of a larger model run by many users with varying levels of connectivity to data.

So, in the script I put the entire UTM grid in geojson, perfect use case for a geojson string, nobody has to worry about external files, I should be able to simply spatially join the extracted raster geometry (center point) to the grid, keep only common, and read the attributes for the containing zone. Right?

Currently I have to take that text, dump it to a file on the user's temp directory, then re-read the file in, and convert it to a feature. (facepalm)

I think this would help alleviate a lot of frustrations and very unnecessary IO operations to disk.

For anyone else who comes across this post, using arcpy.FeatureSet may be a valid option. It accepts ESRI (featureSet) JSON and GeoJSON as inputs. The result can then be copied to disk as a feature class using arcpy.CopyFeatures_management.
