Tile services typically (not always, but almost always) use the Web Mercator projection (3857), because it has nice properties for tiling. It's a safe assumption. In this case, you don't need to assume, since it's in the metadata for the service: https://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer/ This tile pattern (z/x/y) is ...

Found out the solution. The shapefile was read only, I couldn't figure out how to edit the attribute table or create new features. In order to remedy this you have to exit ArcMap. Open the file explorer (or ArcCatalog) go to folder containing shapefile > properties > uncheck read only. Once the shapefile was editable a tool called "Add XY coordinates" was ...

I have never tried this for such a huge amount of rasters; hope this works: GDALTileIndex (Raster > Miscellaneous > Tile Index) on your raster Centroids (Vector > Geometry Tools > Centroids) on the tile polygons (from Step 1) Add Geometry Attributes (Processing Toolbox > Vector geometry) on the centroids (from Step 2)

Do like sailors did in the past: take a mercator map that has the two locations on it, draw a straight line between the two points and measure using a protractor the angle with a meridian, that angle is your bearing. You already found the link to maths and software https://www.igismap.com/formula-to-find-bearing-or-heading-angle-between-two-points-latitude-...

Numbers that big are going to be small units like metres or feet. The earth circumference is about 40,000,000 m, so your numbers might be about 15,000,000m east and 4,500,000m south of some origin point. The most common coordinate reference used these days is Google's Web Mercator system. I can use R to see where your point is in latitude-longitude: > ...

I was using the FCC's API for a bit but for 19k coordinates, the process took several hours. GrantD71's script seemed to work pretty quick on a few hundred but I had issues getting my set done in a timely manner. Geopandas spatial join is the quickest way I've found so far. The TIGER shapefiles are on the Census's website. Import them and your coordinates ...
