If you've looked at any GIS software or application, then you may have been tempted to try and get hold of an Ubuntu machine. This is a popular operating system in the world (particularly for cartography applications). If you're a cartographer, then you'll no doubt have used some version of Ubuntu. And if you're a GIS enthusiast, then the availability of a fully featured (and free) GIS server using Ubuntu on your PC is a sure-fire way to be able to contribute to the community. In this article we will explore the role of the QGIS server in this environment.

When you're running Linux on your computer, there are many programs that will automatically load when you reboot, and some of these will work better with your specific operating system than others. One such program that you may need to load automatically is the \"qgis-server\" command-line tool. It's not strictly necessary but very convenient - and this is the tool that you'll need to load onto your Ubuntu machine. You can just open a terminal window and type this into the field where it lists options; and there you go.
The qgis-server script will load and allow you to import GPDS files from OS Explorer into the browser. Open up the browser and point to the URL of the GPDS server you want to connect to. This should be a physical address in the form of \"http.\" Typically you'll be able to find this in the lower right-hand corner of the screen. If not, simply change the display settings to point to the IP address of your server: the same as you'd point to any other URL on your PC.
Once you've got the URL you need, you can proceed to loading the map onto your QGIS map browser. To do this, simply click on the \"Map\" icon to open the browser; once you're there you can select \"Open Maps\" to load the map on your screen. You'll see a blank black map in the browser; click on the desired location (it may be a city, town or region) and \"Click to Map.\" The map will be loaded and displayed on the screen; you can choose any of the arrows on the lower right-hand corner to zoom in and out of the view. Move the mouse over any part of the map will zoom in to show you that area.
In order to get the data from your Ubuntu computer to your QGIS server, you'll need to add the data to an existing data source. If you're not familiar with how to use the gsis4k snap-in, you'll find the instructions here helpful. Simply locate the folder called \"snap-in-place\" (it'll be blue in color) and open it up. Navigate to \"Add directory\" and enter the path of the GPDS data you'd like to import. Click the \"OK\" button to add the data source.
The final step is to select a layer. To do this, click on the \"Map Layers\" icon in the upper left-hand corner of the screen and click \"New Layer.\" Enter a name for the new layer and drop the data you'd like into the map. When you are satisfied with the map, click on the \"Save\" button to save your map as a JPEG file and place it on your computer's desktop for viewing.
Adding the map to an existing server is relatively easy when using the qgis server software. Even though the snap-in tool might be difficult to learn, once you have learned how to add the map and place it on your server, you can begin creating maps and examine recent trends easily. This server is especially useful for people who want to create bar charts, scatter plots and histograms easily and are familiar with the interface.
The server software is easy to use and comes with many useful features. It'll allow easy importing of geographic data and even exporting data from certain maps that are stored within the program. There are many different types of maps available, including satellite maps of the Earth and satellite images of specific locations. You'll find that the snap-in tool makes it easy to create and edit any kind of map in no time at all. This server Ubuntu is a great program to make your remote server easy to access and understand.
