Enhancing AR Support for MapMint4ME and adding GPS Satellite Tracking

Idea
MapMint4ME (MM4ME) is an android application with the capability to record data on the field without internet connectivity. It gives users the facility to store any kind of alphanumeric data. Users are able to take photos, record their position, and view their current location on a map based on the configuration settings of their MapMint server. When the user returns back to a place with access to the internet, the recorded data can be uploaded back to the MapMint server. In 2019, we added the AR support to the MapMint4ME. The support was to implement ARScale and CloudAnchor support to the MapMint4ME application. The CloudAnchor was used to implement anchors for representing virtual world object. In this project, we aims to Enhance ARScale and CloudAnchor support to MapMint4ME Android Application. MapMint4ME is an android application for MapMint web-service. MapMint is an internet-based Geographic Information System(GIS), designed to facilitate the deployment of Spatial Data Infrastructure(SDI). In an SDI, geographic data, metadata, tools, and the users are connected in an interactive manner in a framework so as to use the spatial information in an efficient and flexible way.

The MapMint is built on top of the ZOO-Project. The ZOO-Project is an SDI manager which gives the users the capability of building their own map and web-applications.

Project proposal
My proposal for GSoC 2020 can be found at: [proposal].

Advantages from this project
While capturing images, sometimes the user wants to add some extra information for more understanding. Current state allows the user to draw shapes and visualize changes in real time. But this AR scene will not be available once the app closes. So the idea is to store Anchors locally and the entire AR scene into some intermediate format which later can be used for visualization at some stage in future by the user hence helping to analyse the data at later stage. Also I am planning to calculate area of selected anchor space and display it to user in real time. Using this feature user will experience changes in real time. Also, planning to extend some UI features for representing GPS details so that we can integrate real world Lat-Long values to Virtual world AR anchors. This will improve process of information gathering.

4th May - 24th May
Community bonding period: What I have done during this period?
 * Joined MapMint Slack Workspace created by mentors which we will be used as a mode of communication over the GSoC 2020 period
 * Introduced myself over the channel and shared my proposal over mailing list for suggestions
 * Mentors setup initial video call for primary discussion and explained me about my tasks during Community Bonding Period.
 * Created a wiki page for the project "Enhancing ARScale and CloudAnchor support to the MapMint4ME Android Application"
 * Updated wiki User page and added my personal information [Link]
 * Updated links on the wiki Google_Summer_of_Code_2020_Accepted page [Link]
 * Environment setup of MapMint4ME android application on my personal system on Android Studio.
 * Gone through documentation of MapMint4ME Android Application.
 * Gone through documentation for MapMint web application.
 * Gone through the working of the application user interface and code
 * Gone through working and setup which had implemented as part of last GSoC.
 * Analyze structure of MapMint4ME app and understand it thoroughly.
 * Discussed with the mentors their expectations over the GSoC 2020 project period.

What am I going to achieve for next week?
 * Implement basic Html UI elements in app.
 * Try to resolve firebase error which I am getting.
 * Try to implement basic retrieve Location ability within MapMint4ME.

Is there any blocking issue?
 * Currently, I am stuck to connect android studio and firebase.
 * Getting constant error from firebase.

Week 1 - 5 (25th May - 28th June)
Coding Phase 1: What I completed this week? What am I going to achieve for next week? Is there any blocking issue?
 * Week 1 (25th May- 31st May)  :
 * Studied how to add location support in Android Application Link
 * Studied and implemented "Get Current Location in Android"[Link]
 * Tested the simple Location support added to Android Application Link
 * Tested this location application on different android devices
 * Show number of satellites and their position relatively to the current position
 * Add this "Get Current Location" to MapMint4ME application
 * MapMint4ME have different language support while combining new part I have to take care of that

What I completed this week? What am I going to achieve for next week? Is there any blocking issue?
 * Week 2 (1st June- 7th June)  :
 * Studied more about GpsSatellite class[Link] and GpsStatus class[Link]
 * Implemented module that shows number of satellites relatively to current position[Link]
 * Display both number of satellites used to fix location and total number of available satellites with respect to current Gps Coordinates
 * Tried to show satellites' position with respect to current position
 * Will complete implementation of satellites' position with respect to current position
 * Integrate GPS Coordinate finder and satellite tracking module to MapMint4ME app
 * Will test this module on different android devices
 * No blocking issue till now

What I completed this week? What am I going to achieve for next week? Is there any blocking issue?
 * Week 3 (8th June- 14th June)  :
 * I added the following methods which give more information regarding GPS satellites currently used to fix locations, Satellite information is required because MapMint4ME acquires data without internet
 * getPrn method returns pseudo random number for satellite
 * getAzimuth method returns azimuth of the satellite in degrees
 * getElevation method returns elevation of the satellite in degrees
 * getSnr method returns signal to noise ratio
 * usedInFix method returns Returns true if the satellite was used by the GPS engine when calculating the most recent GPS fix
 * Currently all above methods give outputs on the android studio console which can be seen at[Link]
 * Integrated last week’s work on MapMint4ME app, for this I created some UI elements and modified the edit.html file to integrate the GPS Satellite Information module
 * To show output of getPrn, getAzimuth, getSnr, getElevation, usedInFix on UI, discussion is going on with mentors about how we can display it on screen
 * Will integrate this in MapMint4ME
 * Test integration with different devices
 * No blocking issue till now
