This tool allows you to add sensor information received from a Context Broker into an ArcGIS Online or ArcGIS Server account.
To install Fiware-ArcGIS you just need to execute the following commands:
$ git clone git@github.com:esri-es/fiware_arcgis.git
$ cd fiware_arcgis
$ npm install
$ node fiware_arcgis.js
With these commands we launched the server and waits until we receive any requests from the Context Broker to process the information and add it to ArcGIS Online / Server.
Let's review the configuration file (config.json):
{
"debug": false,
"port": 4003,
"username": "<your user>",
"password": "<your password>",
"root_url": "www.arcgis.com",
"services_url": "services1.arcgis.com",
"account_id": "<your account id>",
"sensors":{
"traffic" : {
"serviceName": "Traffic sensors",
"route": "/santander_traffic",
"fields": [
["TimeInstant", "esriFieldTypeDate"],
["id", "esriFieldTypeString"],

["status", "esriFieldTypeDouble"],
["vehicle", "esriFieldTypeDouble"]
]
}
}
}Let's see the configurations variables:
- debug: True/False if we want to activate/desactivate the verbose mode.
- port: Listening port
- username: nominal user
- password: nominal user's password
- root_url: www.arcgis.com if we want to user ArcGIS Online; or the url where the Portal for ArcGIS is located in case you want to use ArcGIS Server. It's neccesary to call the generateToken, isServiceNameAvailable and createService methods
- services_url: url where the app is going to hostyour features services (en caso de ArcGIS Online es normalmente: services1.arcgis.com). It's neccesary to call the addFeatures method.
- account_id: Identifier after the root_url. Neccesary to call the isServiceNameAvailable method.
- sensors: It's a JSON object that includes as many sensor descriptions as you need (normally you will add one for each Context Broker suscription), for each sensor we must specify:
- serviceName: name we want to use to host the data
- route: path where the app is going to be listening
- fields: it's an array of arrays with two elements: the attribute name and the field type
The next image shows where you will find the services_url and account_id values in ArcGIS Online:
