Work with coordinates and geographic formats. Confirm the input coordinate system and precision before reusing a result.

10 tools in this category.

• Coordinate distance

  Approximate great-circle distance using a spherical Earth model. Not a driving route or navigation system.

• Coordinate formats

  Convert signed decimal degrees to degrees/minutes/seconds and back.

• Country reference

  ISO codes and Unicode locale data: language names, currency identifiers and time zones. No population, leaders or current political judgements.

• GeoTIFF inspector

  Reads TIFF and GeoTIFF: dimensions, compression, IFD tags, GeoKeys and georeferencing from pixel scale and tiepoint.

• GeoJSON simplification

  Simplifies lines and polygons with Douglas-Peucker, keeps rings closed and reports area, length and point reduction.

• Vector tile encoding

  Turns GeoJSON into a Mapbox Vector Tile version 2: layers, attributes, command-encoded geometry and a decode check.

• OSM XML import

  Parses OSM XML: nodes with coordinates and tags, ways with references, relations, bounds, tag statistics and missing references.

• OpenPLZ address lookup

  Check postal code and locality for DE/AT/CH/LI.

• Geological units and columns

  Macrostrat stratigraphic units or columns at a coordinate: age, lithology, thickness and colour.

• OSM features by tag

  Select OpenStreetMap features by tag inside a bounding box: name, type, coordinates and link.
