[Fiware-tech-help] GeoProperty issues

[Haghgoo, Maliheh]

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": {

>         "type": "Property",

>         "value": [

>                [32.321,-64.757],

> }'



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 :

{



    "type": "http://uri.etsi.org/ngsi-ld/errors/InternalError",

    "title": "error filling a scope",

    "details": "invalid coordinates"



}



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,
