Upload GPS points to Track using Python

JPMeijers — Wed, 10 Nov 2021 12:46:25 GMT

I have a couple of hardware GPS trackers which we install on vehicles. The gps points from these trackers arrive on one of my servers, from where I want to push the locations into Arcgis Online.

I have tried this piece of Python code to append a track point to the track layer:

gis = GIS(username="redacted", password="redacted")

izinto_item = gis.content.get("redated")
feature_layer = izinto_item.layers[1]

new_feature = {"geometry": {"x": redacted, "y": redacted, "spatialReference": {"wkid": 4326, "latestWkid": 4326}}, "attributes": {"activity": 0, "altitude": 511.228589377366, "app_id": "izinto", "battery_percentage": 55, "battery_state": 1, "course": None, "device_id": "test", "floor": None, "horizontal_accuracy": 46.4931761266777, "location_source": None, "location_timestamp": 1636544141380, "session_id": "test", "signal_strength": None, "speed": 0.646095156669617, "vertical_accuracy": 7.64551688182702, "full_name": "redacted", "category": None, "created_user": "redacted", "created_date": 1636544328798, "last_edited_user": "redacted", "last_edited_date": 1636544328798}}

feature_layer.edit_features(adds=[new_feature])

Running this code however results in an error:

Traceback (most recent call last):

What would be the proper way to upload GPS tracks that are obtained from a hardware GPS tracker device?

Does excluding the created_user, created_date, last_edited_user, and last_edited_date attributes from the feature make a difference? Those attributes are typically automatically set by the feature service if they were added to the feature service when editing was enabled.

Thanks for the suggestion @J_R_Matchett. I've done the following:

new_feature = {"geometry": {"x": 12.345, "y": -12.345,
                            "spatialReference": {"wkid": 4326, "latestWkid": 4326}},
               "attributes": {"altitude": 511.228589377366,
                              "battery_percentage": 55, "device_id": "test",
                              "location_timestamp": 1636544141380, "signal_strength": None,
                              }
               }
feature_layer.edit_features(adds=[new_feature])

But now I get a different error:

Traceback (most recent call last):
File "/home/jpmeijers/PycharmProjects/arcgis-update-feature/track.py", line 59, in <module>

File "/home/jpmeijers/PycharmProjects/arcgis-update-feature/track.py", line 55, in main

I'm starting to wonder if this Tracks feature is only supported by the mobile apps, and not third party integrations. Does anyone have a good suggestion how I can upload GPS tracker data into Arcgis Online?

I have now create a new item with only a points layer. I can successfully upload GPS tracker points to this points layer, using application credentials.

For reference my full code

    params = {

    }
    request = requests.get('https://www.arcgis.com/sharing/rest/oauth2/token',
                          params=params)
    response = request.json()
    token = response["access_token"]
    return token


def main():
    # token = get_token()
    # gis = GIS(token=token,
    #           referer="https://redacted")
    gis = GIS(username="redacted", password="redacted")
