In my wwwroot folder, I have the following JSON file:
[
{
"type": "feature",
"geometry": {
"type": "point",
"coordinates": [ 54.057122, 6.081795 ]
},
"properties": {
"name": "prachtige rotonde"
}},
{
"type": "feature",
"geometry": {
"type": "point",
"coordinates": [ 54.059813, 6.073641 ]
},
"properties": {
"name": "oude wielerbaan"
}}
]
The thing is, they end up somewhere in Arabia and not near the Netherlands, where they should be. Google maps and openstreetmap itself do interpret these coordinates correctly.
My guess is that you confused longitude with latitude when interpreting a local GEOJson. Another reason why I suspect this, is because the sample code provided on the readme on NuGethttps://www.nuget.org/packages/LeafletForBlazor/1.0.6#readme-body-tab first sets the longitude (y-axis) and then the latitude (x-axis), while normally x comes before y.
