Web Map Tile from Coordinates

web map tile from coordinates calculator online

Use web map tile from coordinates online for latitude deg, longitude deg, zoom. Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.

How to use it

Enter latitude deg. Set longitude deg, zoom. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

Calculation method

tile = tile(latitude_deg,longitude_deg,zoom) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply web map tile from coordinates to the case below, keeping the displayed units and assumptions. Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.

Web Map Tile from Coordinates — worked case

Settings: longitude deg: 19.8; zoom: 10

Input:

41.3

Calculated result for these inputs:

Output:

{
  "tile": {
    "x": 568,
    "y": 382,
    "zoom": 10
  }
}

Choose the right tool

Choose great-circle tools for shortest spherical paths and rhumb tools for constant bearings. Spherical models differ from ellipsoidal survey calculations. Web-map tiles have latitude limits and grid bearings require a stated convergence convention.

Limitations and common mistakes

• Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.
• Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
