uDig Quickstart

uDig (User Friendly Internet Desktop GIS) ist ein Desktop GIS-Client zum Anzeigen und Editieren von räumlichen Daten.

Dieser Quickstart beschreibt, wie Sie:

  • load a map layers from a shapefile and Web Map Service (WMS)

  • Verwenden der Standardwerkzeuge zum Navigieren in der Karte

  • Anpassen der Farbe für die Darstellung von Objekten (Stil)

uDig starten

  1. Geospatial ‣ Desktop GIS ‣ uDig im Startmenü des Desktops wählen

  2. nach einem Moment wird die Anwendung gestartet und ein Begrüßungsbildschirm angezeigt


If you have any difficulties, or are running uDig please review the Running uDig reference page.


  1. When you start up uDig for the first time the Welcome view takes up the entire display. This screen has links to tutorials, documentation and the project website.

  2. Click the arrow labelled Workbench in the upper right corner, to reveal the contents of the uDig workbench.


Die Willkommensansicht können Sie jederzeit wieder herstellen, indem Sie im Applikationsmenü Help ‣ Welcome auswählen.


Im Arbeitsbereich gibt es einen Bereich für die Karten, der umgeben ist von Ansichten, die das Arbeiten mit der Karte unterstützen. Viele Ansichten zeigen dabei kontextbezogene Informationen zur aktuell geöffneten und ausgewählten Karte an.


Oben ist ein typischer uDig -Arbeitsplatz mit Ansichten für die

  1. Kartenlayer Layers (1),

  2. Kartenprojekte Projects (2),

  3. dem Katalog Catalog (3) sowie

  4. der Karte (4)

zu sehen. Die Ansichten und deren Verwendung werden weiter unten beschrieben.


Um einen ersten Eindruck der Anwendung zu gewinnen, werden wir Beispieldaten laden, die auf der DVD enthalten sind.

  1. Wählen Sie Layer ‣ Add vom Applikationsmenü. Es öffnet sich der Wizard Add Data.

  2. Wählen Sie in der Liste der Datenquellentypen Files aus.

  3. Klicken Sie auf die Schaltfläche Next. Es öffnet sich ein Dialog zur Auswahl von Dateien.

  4. Die OSGeo-Live DVD enthält Beispieldaten im Ordner:

    • ~/data (als Kurzform zu /usr/local/share/data)

  5. Wählen Sie die folgende Datei aus dem Ordner natural_earth2 aus:

    • ne_10m_admin_0_countries.shp

  6. Klicken Sie auf die Schaltfläche Open

    • Eine neue Karte wird geöffnet, die den Inhalt des Shapefiles anzeigt. Der Name und die Projektion für die Karte wurden vom Shapefile übernommen (Standardverhalten)

    • Die Katalogansicht (Catalog view) wurde aktualisiert und enthält nun einen Eintrag für das Shapefile ne_10m_admin_0_countries.shp. Diese Ansicht enthält als Liste alle Resourcen, die in den unterschiedlichsten Karten der uDig Anwendung verwendet werden.

    • The Layers view shows a single layer is displayed on this map. This view is used to change the order and appearance of information in your Map.

    • The Projects view has been updated to show that your map is stored in projects > ne 10m admin 0 countries. You can have multiple projects open at a time, each project can have several maps.

  7. Open up the ~/data/natural_earth2/ folder on the desktop

  8. Drag HYP_50M_SR_W.tif onto the Map Editor, a new layer is added to to the map.

  9. You can see the order the layers are drawn in the layer view. Right now the HYP_50M_SR_W layer is drawn on top of the ne 10m admin 0 countries layer.

  10. Select the HYP_50M_SR_W layer in the catalog view and drag it to the bottom of the list



One of the most common questions asked when uDig is considered for an organization is how much memory the application uses. Unlike most GIS applications uDig can get by with a fixed amount of memory. The above shapefile is not loaded into memory, we have a policy of keeping data on disk and drawing data like this shapefile onto the screen as needed.


You can also drag and drop shapefiles directly into the uDig application!


You can control where in the world the Map Editor is looking by using the navigation tools in the tool bar along the top of the screen.

  1. The ZOOM Zoom tool is available by default

    • Use the zoom tool by drawing a box using the left mouse button around the area of the world you wish to see.

    • To zoom out draw a box with the right mouse button. The current map extents will be located within the box you draw.

  2. The PAN Pan tool can be used to scroll around your map with out changing scale.

  3. There are also several navigation buttons that can be used at any time:

    • SHOWALL Show All, can be used to return to the full extents at any time

    • ZOOM_IN Zoom In and ZOOM_OUT Zoom Out can be used to change the scale by a fixed amount.

    • You can use Navigation Back BNAV and Forward FNAV in the menu bar to cycle though previously visited locations.


Most tools allow you to Pan by holding the center button and control the scale using the scroll wheel.

Web Map Server

One of the reasons to use an application like uDig is to access all the great free geospatial information available on the web. This section covers the use of Web Map Servers which make available layers of information that you can mix into your own maps.


If you are not connected to the Internet run Geospatial ‣ Web Services ‣ GeoServer ‣ Start GeoServer for a local WMS. The script will open a page with a „Service Capabilities“ section and two links for WMS Services you can drag into your empty map.


You can copy a WMS URL (e.g. for WMS 1.1.1) from right panel of GeoServer Welcome page and „paste“ it either on the Map view or the Layers view. A wizard shows you the layers you can add to the Map. You can also connect to Web Map Servers using the Add Data (Layer ‣ Add…) Wizard and paste WMS URL right there.

  1. Select File ‣ New ‣ New Map from the menu bar

  2. Change to the Web view, click on the tab next to the Catalog view to reveal the Web view.

  3. Klicken Sie auf den Link WMS:http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?Service=WMS&VERSION=1.1.0&REQUEST=GetCapabilities

  1. From the Resource Selection page we are going to choose the following layers:

    • Elevation/Bathymetry

    • Parks

    • Cities

  2. Press Finish to add these layers to your map

  3. Use the ZOOM Zoom Tool to move closer to one of the Parks

  4. Switch to the INFO Info Tool and click on one the parks to learn more about it


You can switch between the zoom and info tools by pressing Z and I on the keyboard.


  1. Select the project > ne 10m admin 0 countries, you can double click to open this Map, or Right Click and choose Open Map

  2. Select the countries layer in the Layer view

  3. Open up the Style Editor by right clicking on ne 10m admin 0 countries layer and choosing Change Style

  4. We are going to change a few things about how countries are displayed

    • Line: Click Border, click on the Color button and change the color to BLACK

    • Fill: On Tab Fill uncheck the box enable/disable fill to turn off fill

    • Label: On Tab Labels check the box enable/disable labeling, and choose the attribute NAME from the list of attributes

  5. Press Apply to see what this looks like on your Map, the Layer view will also be updated to reflect the current style

  6. When you are happy with the result you can press Close to dismiss the dialog


Some files include style settings. The Style definition can be found in files with the *.sld extension. The name itself should be equal to the file containing the data. If such a Styled Layer Descriptor (SLD) file exists, the style will be applied automatically.

Sometimes it is a bit hard to see what is going on with layer providing much details. To get focused on the task you like to work on, you can choose Map ‣ Mylar from the menu bar. Using the Layer view select different layers in turn to see the effect. You can turn off this effect at any time using Map ‣ Mylar from the menu bar.


Weitere Aufgaben

Hier sind einige zusätzliche Herausforderungen für Sie zum Ausprobieren:

  1. Try viewing your own GIS map layers, or try adding a layer from a Web Feature Service (WFS)

  2. Try styling the WFS layer.
