Percival vs Coordinate Converter

Marine Logbook - Voyage & Fix Logging: Records position fixes, averaged speed, course, and timestamps over the course of a passage. - Observations & Voice Notes: Allows sailors to record voice memos and text notes tied to specific GPS fixes. - Noon-to-Noon Calculations: Calculates traditional passage-making metrics, such as 24-hour day runs (noon-to-noon) and daily distance made good. Live Navigation Instruments - Displays passage data including averaged Speed Over Ground (SOG), Course Over Ground (COG), Velocity Made Good / Velocity Made on Course (VMG/VMC), and range/bearing to destination. - AIS & NMEA Integration: Ingests marine NMEA 0183 data streams and AIS vessel feeds (both local NMEA feeds and internet AIS) to monitor surrounding vessel traffic. ETA windows - Computes ETA estimates based on three velocity calculations. Mapping - Map Views & Waypoints: Plots the voyage track, note markers, and live positions over map layers (including NOAA charts and satellite tiles). Sharing & Passage Data - Standard & Native Exports: Exports trips in standard formats (.gpx, .csv) as well as native Percival voyage backup files (preserving tracks, notes, and voice clips) to share with other crew and sailors.

Read coordinates from your camera or an imported image, use your live location or select a point on the map, and convert between reference systems. Keep your results ready for the next step. CoordCap is free to download. Manual conversions, the built-in WGS 84 / UTM workflow, and Auto UTM on the map are free. CoordCap PRO is an optional, one-time in-app purchase that unlocks other map targets, plus capture and saving with additional transformations. No subscription. INCLUDED FOR FREE - Enter coordinates manually and convert them using the built-in WGS 84 / UTM workflow or transformations you add. - Read original coordinates with your camera or from imported images. - Convert between WGS 84 latitude/longitude and UTM using the built-in workflow. - Capture, review, save, and export individual coordinates and coordinate lists using the built-in WGS 84 / UTM workflow. - View, copy, and save map coordinates with Auto UTM. Use your live location or select a point with the crosshair; the UTM zone and hemisphere update automatically. - Copy and share manual conversion results. REQUIRES COORDCAP PRO - View, copy, and save map coordinates using any target other than Auto UTM, in both Live and Target modes. - View converted coordinates from your camera or imported images using transformations you add beyond the built-in WGS 84 / UTM workflow. - Capture and review coordinate lists using those additional transformations. - Save individual results using additional transformations, including results entered manually. - Save and export captured coordinate lists using additional transformations. Manual conversion with an added transformation is free. Using that transformation to view converted map coordinates, for converted camera or image capture, or to save results requires PRO. Auto UTM on the map stays free, including copying and saving. The built-in WGS 84 / UTM workflow also stays free, including capture, saving, and export. REVIEW BEFORE YOU USE Check captured readings, correct coordinates, and choose which rows to include before exporting. Coordinate recognition can make mistakes, so always review results against your source.
