Worked examples

Use this for the specific transformation described above. Start with the fixed sample and compare its result before replacing it with your own representative input.

Reproducible worked example

Settings: Output: geojson

Input:

POINT (19.8187 41.3275)

With the input and settings above, the tool produces:

Output:

{
  "type": "Point",
  "coordinates": [
    19.8187,
    41.3275
  ]
}

The example returns an object with 2 top-level fields. The fields “type”, “coordinates” identify the returned values or sections.

Limitations and common mistakes

Two-dimensional geographic coordinates in longitude/latitude bounds; no SRID, Z/M dimensions, geometry collections or topology repair.
Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
