+# CrowdDensityMapper
+
+The application "Crowd Density Mapper" was developed in the context of the course 
+"Advanced Geospatial Web Technologies" at the University of Münster.<br>
+With the app the following issue is addressed: 
+"Several areas around a stadium are often crowded before and after football games. 
+The app can allow the user to view and potentially avoid these crowded areas by analyzing 
+volunteered smartphone trajectories."
+
+###Components
+For the execution of the application, three components are needed: A Web Processing Service,
+a spatial database, and a front-end. This repository contains the code for the **front-end component**.
+The code for the database component can be found here: https://github.com/LEinfeldt/AdvancedGeoWeb<br>
+
+###Front-end
+The front-end is based on *HTML*, *CSS*, *JavaScript*, and *PHP*. 
+It has a responsive design (using *Bootstrap*) and was developed for usage in Chrome (mobile and desktop).
+During the project, the application was hosted on an *Apache2* server. 
+
+The Application consists of two pages. One page is an "About" page showing important information and hints.
+The other one is the main page and shows a *leaflet* map with different layers. 
+One layer displays a density map, processed by the Web Processing Service. 
+A time-slider can be used to examine the temporal progress of the density.
+ 
+For calculating the density of the crowd, the users coordinates are used. 
+For this reason, the user of the app is requested to activate the GPS device in his smartphone and allow 
+the applicaton to use his actual location. 
+If the user does not allow the usage of the location he can't use the application.
