From OSGeo
Jump to navigation Jump to search



The Idea is basically about introducing the Augmented Reality experience in the present MapMint4ME project by building the AR Draw feature in UNITY 3D and adding its intent in the MapMint4ME project. AR Draw - It’s an AR experience that just lets you draw simple lines using a line renderer in 3D space by touching your screen with a single finger or can be with multiple fingers and moving the phone around the space.

MapMint4ME means MapMint 4 (for) Measure and Evaluation, It is an Android application that allows you to edit geolocated data in online or offline mode.

Project proposal

My proposal for GSoC 2021 can be found here.

Advantages from this project

This project will bring the Augmented Reality capabilities to the software with better UI and UX parts for the MapMint4ME AR Draw experience. User Experience for GIS services puts UX at the heart of your GIS applications, increasing usability for GIS apps.
