Hi there,

Within the scope of research project powered by FIWARE in energy sector. We are going to have ontology include in our project therefore NGSI-ld is very well fit to our concept. But I faced some issues regarding usage of GeoProperty. Most important one is related to geolocation. There is no fresh document which can help me I found several links and info but none of works.

I posted :

curl -iX POST \

> 'http://IP:1026/ngsi-ld/v1/entities' \

> -H 'Content-Type: application/ld+json' \

> -d '

> {

> "id": "urn:ngsi-ld:ParkingSpot:santander:daoiz_velarde_1_5:5",

> "type": "ParkingSpot",

> "status":

,

> "category":

,

> "refParkingSite":

,

> "name":

,

> "location":

,

> "@context": [

> "https://raw.githubusercontent.com/Maliheh-Haghgoo/N5GEH/master/Core-Context",

> "https://raw.githubusercontent.com/Maliheh-Haghgoo/N5GEH/master/Device.jsonld" ]

> }'

And I would like to query my entities based on location. Here is my Get request :

http://IP:1026/ngsi-ld/v1/entities/?type=Sensor&georel=within&geometry=polygon&coordinates=%20[[25.774,-80.190],[18.466,-66.118],[32.321,-64.757],[%2025.774,-80.190<http://IP:1026/ngsi-ld/v1/entities/?type=Sensor&georel=within&geometry=polygon&coordinates=%20%5b%5b25.774,-80.190%5d,%5b18.466,-66.118%5d,%5b32.321,-64.757%5d,%5b%2025.774,-80.190>]]

This is an error that I'm receiving :

Actually with several tries it still does not work and I'm getting errors , I would appreciate it if you could help me in this regard.

Cheers,
