WorldNote Mapper is a multipurpose app for geolocated notes, GPS field measurement, route recording, navigation, and satellite data checks. Whether you’re exploring a trail, planning a trip, documenting a site, or building a personal map of places that matter, complete with a geolocated photo gallery, you can capture the details and find them again when you need them.

More than a field-measurement GIS tool. More than a geolocated annotation app.

• Save positions and landmarks

• Draw distance lines and measurement fields

• Record GPS tracks as you travel, then review distance, duration, and route geometry

• Customize map objects with colors and icons

• Add names, descriptions, photos, and other details; categorize everything

EXPLORE & ORIENT

KEEP YOUR FIELDWORK ORGANIZED

• Browse saved objects and open their details to edit or update

• Capture and edit photos to document places and observations

• Keep tracks, waypoints, and measurements together in one visual workspace

COMPREHENSIVE AND PRIVACY-CONSCIOUS

• Notes, coordinates, recorded routes, and attachments stay entirely on your device, nothing is sent to someone else’s server

• Import and export geospatial data in GPX, KML, and JSON

• Generate PDF and map-image outputs for reports, records, or sharing

• Carry a complete portable copy of your mapped information, including image attachmentsIT’S

NOT JUST “WHAT” THAT MATTERS, BUT ALSO THE “HOW”

Built to high standards with decades of software-development experience, WorldNote Mapper packs every function into a highly optimized 10 MB APK—smaller than many apps that offer only a fraction of its capabilities. No piles of libraries for features that can be implemented natively with current methods. No bloat. No slop.
