Batch Processing

Efficiently process massive CSV files with thousands of A → B coordinates in seconds.

Global Formats

Supports Decimal Degrees (DD), Degrees-Minutes-Seconds (DMS), and Decimal Minutes (DDM).

Strict Validation

Choose between Permissive mode for bulk processing or Strict mode for data integrity.

Technical Specifications

Input Requirements

The CSV must include headers: name_a, lat_a, lon_a, name_b, lat_b, lon_b.

Coordinate Systems

DD: 48.858056 (Decimal)
DMS: 48°51'29.6"N (Secs)
DDM: 48°51.4'N (Dec. Mins)

Output Data

Ektaon enriches your data with:

Distances in km and miles
WGS84 Normalized coordinates
DMS conversion for all points
Nearly-identical flags (11cm tolerance)

CLI Usage

Example Command

# Standard run
ektaon --input points.csv --output results.csv --input-format=ddm

# Strict mode (stops on first invalid line)
ektaon -i input.csv -o output.csv -f dms --strict
