Geographic masking is a technique used to basically move your data around so not to give away the exact geographic coordinates of individual level data. This is done when locations of individuals (like in health data, crime data, or endangered species data) need to be “anonymized” so they cannot be re-identified through reverse geocoding.
Everything runs client-side in your browser, meaning there’s nothing to install, data never leaves your computer, and as a result nobody except you ever sees your confidential files. It is a safe and secure way to anonymize spatial data. Finally, you can map your secret fishing spots and share them with others without giving away the exact locations! Check it out!
