POIs are batch added in the following format (a JSON array of objects):
[
{
"name": "name_of_node_1",
"coords": [lon, lat]
},
{
"name": "name_of_node_2",
"coords": [lon, lat]
}
]
Coordinates are of the format longitude/latitude in decimal degrees, multiplied by 1e6. So for example, 58.234234 is entered as 58234234.
