Gpstrack4maas
Currently I am improving my skills in front-end development. Therefore I have developed a small application in Angular with a Firebase backend. It is constantly under construction but you are invited to look at it.
The idea of the application is that you can share gps tracks and view them on a map. So if you are interested to view, download or upload tracks just click here .
On older version of this application made with Google Web Toolkit (GWT) and the Google App Engine as backend is still running and can be found here. Unfortunately I have lost the latest version of this software so the application is stale in terms of development.
PhotoLabeler
This is a Java application I wrote long time ago (2004), but since I still use it it might be handy for you too. It is a Java Swing application . PhotoLabeler is a tool I made to add gps location data and some tags to digital photo’s. You can do this with groups of Photo’s. Installation info can be found here . Detailed info
Progressive WebApp example
Just to see how easy it is to make a progressive web-app I have made an example. You can go to the website of the app and on Android save it as an app on your home-screen. also of IPhone you can put the app on your screen like an application.
The source of the code is found on GitHub
