## Creating a Central Class from which to Execute the Whole Programme
## Step 1: Creating a Central Class from which to Execute the Whole Programme
To make the whole programme run smoothly without the user having to figure out which classes to execute and in which order, we simply applied our previously gained knowledge about modularity and decided to create a set of non-executable classes that will be called from the main class in the correct order.
The corresponding .java file for this class can be found [here](https://git.sbg.ac.at/s1080384/EoT/-/blob/main/.java%20Files/execute_programme.java).
## Download WMS from Web
## Step 2: Web Map Service
Another key component of our project is to access, download and integrate a Web Map Service (WMS) of Boston. This task was divided into two sub-steps:
### 2.1: Connecting and Downloading WMS
First, we created a non-executable class that contains a method **getMap()** that:
> 1. creates a WebMapServer object
> 2. tests the URL
> 3. retrieves the WMSCapabilities and information about the service
> 4. sends a fully configured GetMapRequest
> 5. asks the user if they would like to see information on the service (and either shows it or moves on)
> 6. writes the image in .png to the local directory
When this method is called from the main class, the user will be kept updated and will see the following on the console:
```
Accessing WMS and downloading .png of Boston to local directory at: C:\Users\Christina\Documents\EoT\boston.png...
Testing Heigit's wms service URL...
URL vaid.
No errors in communicating with the server.
Would you like additional information on the WMS service while the programme runs? Type Y for yes or anything else for no and hit enter.
y
The WMS capabilities are being retreived from a server called: OGC:WMS
And the server's title is :OSM-WMS Uni Heidelberg.
The requested image will be stored as a .png with dimensions of 1000 x 1000 pixels.The coordinate reference system is set to ESPG:4326
Requested URL: http://maps.heigit.org/osm-wms/service?REQUEST=GetMap&FORMAT=image%2Fpng&SRS=EPSG:4326&BBOX=-71.13,42.32,-71.03,42.42&VERSION=1.1.1&STYLES=default&SERVICE=WMS&WIDTH=1000&HEIGHT=1000&TRANSPARENT=TRUE&LAYERS=osm_auto%3Aall
Image was successfully saved at: C:\Users\Christina\Documents\EoT\boston.png
Step 1 completed.
