I have extracted these coordinates from geolinkedata And I don't know what system they are using:
What I know is that they correspond with these WGS84 Coordinates:
I am trying to use the SPARQL interface of linkedgeodata (2) to match some streets names I know, with instances of streets in their SPARQL Endpoint. To do so, I need to filter all the streets to keep only those that are placed in the surroundings of Cáceres.
If the coordinates of the streets in the SPARQL interface of linkedgeodata (2) were in WGS84 I wouldn't have any problem, because I understand those coordinates and I know how to work with them.
The problem is that I really don't know what system they are using, that's why I searched a street manually:
whose first node is:
Which has the following coordinates:
Then I searched this same street in the OpenStreetMap (which is where the data of linkedgeodata comes from):
I saw the coordinates in wgs84:
This approach I used was possible because I knew this street beforehand, so it is not replicable to all the other street names.
What I need:
I need to know what kind of coordinates are
(-15.4400797 28.131791000000003) to convert all the other streets' coordinates automatically to WGS84, the format I understand and the one I feel comfortable working with.
