Conversion supports CSV files containing Geometric Points defined by separate fields for Latitude and Longitude. The following case-insensitive field name variants are accepted:

• Latitude: lat, Lat, LAT, latitude, Latitude, LATITUDE
• Longitude: lon, Lon, LON, lng, Lng, LNG, long, Long, LONG, longitude, Longitude, LONGITUDE

Filtering presupposes that the CSV file includes all or any of the predefined case-insensitive field names: Passages, Type, and Region.

• If filtering fields are absent, the entire dataset will be converted to GeoJSON and KML without filtering options.
• If filtering fields are present, all their unique values in the dataset are displayed as options in their respective select element.
• You can combine filtering by choosing options from all fields.

You can switch between server files (via the select element) and your own local files (via the File System). Selecting one will replace the other.

Two versions of KML files are generated:

• One includes field names and values as ExtendedData, using <Data> and <value> elements.
• The other embeds all fields in a Description element with HTML formatting, suitable for platforms like Google Maps.
