signmopa.blogg.se - Map satellite street view

You're unlikely to get the accuracy and precision you're looking for from the imagery on Google Maps. (Had this on SO ( ) first but removing it there since it might be better suited here) Is there a way I can get coordinates of a building from a satellite layer to map the outlines of the same building on the map layer? If so, how could I do it? Plus I somehow need to iron out these differences. I assume that since the Earth is round and a map is flat those derivations exist, but I am not sure. Thus, I went ahead and transformed the satellite coordinates EPSG: 4326 to EPSG 3857 and sent those to my database.

Google Maps is in a projected coordinate system that is based on the WGS84 datum.

Google Earth is in a Geographic coordinate system with the WGS84 datum.

I read here EPSG 3857 or 4326 for GoogleMaps, OpenStreetMap and Leaflet, that: Sometimes it's to the left and sometimes it's to the right. This happens to almost all buildings I am trying to pinpoint. Note that the point is about 1cm to the right within the building.

But if I change the layer to the normal map view I get this result: Note that the point is exactly on the edge. I get the following image in satellite view:

My main problem with almost all my coordinates is that the Google Maps satellite layer is not congruent to the street view. Send coordinates to webmap with SRID 4326.I am using a satellite image to get the correct latitude and longitude and then I send the coordinates via an API.

I am trying to draw the layout of a building and project them to a web map using Django and Leaflet.
