Output and database

Live Link: Having this box checked means that changes you make to the view are immediatly reflected in the layout. By turning this option off (uncheck the box) you remove the link and the layout view captures the current view state. Changes you make to the view will no longer be reflected in the layout.
Scale: By default, ArcView scales the contents of the view window automatically; that is, if you change the size of the view frame in the layout, the contents of the view frame will be scaled to fit inside the resized frame. If you want the contents of the view frame to be displayed at the same scale as the view, irrespective of the view frame size, you can choose Preserve View Scale from the Scale drop down list. You can also specify the scale directly by choosing UserSpecified Scale.
Extent: By default, if the contents of the view frame are smaller than the view frame, ArcView will try to fill the view frame with data from the view. This may result in data appearing in the layout that is not currently visible in the current extent of your view. If you don''t want this to happen, set Extent to be Clip to View. Use Clip to View if you want to ensure that only those features currently visible in your view will be displayed in the layout.
Display: By default, ArcView only displays the contents of the view frame in your layout when the layout is active. This saves time when you are working with a live-linked view that contains a large number of features, because ArcView won''t draw them in the layout each time you change your view. To override this, you can set Display to be Always.
Quality: If your view frame contains a large number of features, you can always save time by setting Quality to Draft instead of Presentation. in this way, the contents of the view frame will not be fully drawn either on screen or when you print the layout. When you''ve finalized your layout, you can then set the Quality back to Presentation prior to your final print out.
For now only change the Extent option to be Clip to View, then click OK to proceed. Use the Pointer tool to move and resize the view frame once it appears on the layout. If you would like to add a border to the map view click the button.

Adding Other Map Components
To add a north arrow, select the north arrow icon from the drop down tools bar (fourth in list). Choose an arrow from the resulting box. Use the Pointer tool to move and resize the arrow once it appears on the layout. To add a title to your map, click on the Insert Text Tool . In the resulting window type in a suitable title. To change text attributes select the text using the Pointer tool and then choose Window - Show Symbol Window. In the resulting dialog box, click on the Font button and make changes using the Font Palette.

Next you will insert a scale bar. A scale bar on a layout shows the scale of the contents of the view frame it is associated with. If the scale of the view frame''s content changes, its associated scale bar will change automatically too. Click the Scale bar frame tool from the drop down tools bar (third in list). Use the mouse to define where you want the scale bar to be placed. The scale bar properties dialog appears. Choose the name of the view frame already in the layout, that you want the scale bar to be associated with (in this case The World) and choose the other properties of the scale bar (ie. style, units etc). Click OK to finish. Use the Pointer tool to move and resize the scale bar after it appears on the layout.

Note that, if you want to edit any of the components on your layout, simply double click on that component. The properties will the be displayed in a dialog window. You can then make any changes.

The final component to complete your map is the legend. Like the scale bar, the legend is associated with one of the view frames on the layout. Again, if the view properties change the legend will be updated. Click the Legend Frame tool from the drop down tools bar (second in list). Use the mouse to position where the legend will be placed. In the dialog that appears select the name of the view frame to associate with (in this case The World) and click OK. Use the Pointer tool to move and resize the legend after it appears on the layout.

Finally, use the Text tool to add some descriptive information about the map and also your name.
All the neccessary componets of a map should now be in your layout. Use the Pointer tool to select, move and resize any of the layout components to make it look good. Your layout should contain all those that appear in Figure iii., although it will not neccessarilly look the same.
As a last touch, you should name your layout for future reference. Click the Layouts icon (shown in Fig. i.) from the project window contents. Then select Project - Rename from the main menu and input a new name, click OK to proceed. When you are satisfied with your layout you may move to the next (and last) lesson. Make sure and save your project by clicking the button or by selecting File - Save Project from the main menu.

Output
Once you have set up the view or layout, you will no doubt want to output it for use in hardcopy maps or in image file formats for inclusion in reports. Views, Layouts, charts and for that many any graphics created in ArcView can be output by using the options under File in the main menu. Generally however, you will be outputting layouts.

For this the last lesson you are required to complete two tasks using the layout you created in the previous lesson;

Create a hardcopy (print out)
Create a Windows BMP image file.
Use the instructions below to complete the assigned tasks.

Printing
Select File - Print ... from the main menu.
In the dialog that appears, specify the print options you wish to use.
Exporting to Other Formats
You can export a layout to a graphics file so that you can manipulate it in another graphics program, incorporate it into a report or presentation you are creating with a different application, or send it to a commercial printer. Supported export formats include EPS, Adobe Illustrator, CGM, BMP and WMF. Other formats may also be added so to check the formats currently supported, search ArcView''s online help index for exporting a layout.

Select File - Export ... from the main menu.
In the dialog that appears, choose the file format you wish to export to and specify the name and location of the file that will be created. You can specify the output resolution of this file by pressing the Options button in the Export dialog window.
NOTE: To create a PostScript (.ps) file from a layout, use the Print option not the Export option form under the File menu

Setting up your Database
Before you can do any analysis you need to create and manipulate your spatial database. For this exercise you will use a dataset that covers an area located in central Australia, You have already downloaded the data, now you need to tell ArcView where that data is located. Start ArcView and create a new project file. Save the project and name it as ''Pooncari.apr''. Now you are ready to begin filling your new project. Create a view (remember to set the properties correctly - map units are metres and distance units are kilometres), name it Pooncarie and add the themes contained in your GISDataPooncari data directory.

Remember to add themes you can use the button, navigate to the data directory then double click on the names of each theme. To open multiple themes click on the theme names while holding down the shift key or double click on a particular theme name and repeat the process for other themes. When all themes are selected click the OK button.

Learning to produce a well presented view is essential for cartographic output. To make a good view you need to:

Organise the layers of coverages by dragging themes up and down. Generally you should place point and line coverages above polygon coverages.
Adjust symbols and colours then link maps to an attribute field using the Legend editor by double clicking the themes name.
Turn on or off particular themes by ticking (i.e. click left mouse button on the small box to the left of the theme name) the relevant theme.
Setting up the View
For this exercise you should set up your view to contain the following themes with the following colours and symbols. So go ahead, add the relevant themes and edit their legends so that they appear as described.

Land Systems (landsys theme using attribute feature): Set as the background (lowest theme in list) with the colour specification as listed in the table below. All outlines should be coloured light grey.

Feature Colour
Alluvial Plains Green
Dunefields Orange
Hint: Add the landsys theme. Turn on the landsys theme (tick it). Double click the landsys theme. In the Legend Editor select Legend Type as Unique Value. In the Values Field select Feature. Click on the coloured box next to each feature and change the colour and outline (light grey) to the ones listed above. Then click Apply to Finish.

Roads (roads theme using attribute roads-id): Place above landsystems and use the colour and style specifications listed in the table below.

Roads-id Colour Line Style
1 none none (0)
2 black thick (1)
3 red medium (0.5)

Hint: Add the roads theme. Turn on the roads theme (tick it). Double click the roads theme. In the Legend Editor select Legend Type as Unique Value. In the Values Field select Feature. Click on the coloured line next to each feature and change the colour and line style to the ones listed above. Then click Apply to Finish.

Property Boundaries (property theme): Specify no attribute only set the line to a grey colour with a thin line style.

Hint: Add the property theme. Turn on the property theme (tick it). Double click the property theme. In the Legend Editor click on the coloured box (symbol) and change the colour to none, the outline to grey and the line style to thin (0.1). Then click Apply to Finish.

Your view should now appear like that in Figure i.

Your database is set up so it is time to make some basic queries. You will make both spatial and attribute queries and answer some questions relating to these processes.

Spatial Query
Turn on (tick) the bores theme (point coverage) and move it to the top of the theme list in the view contents. If you wish change the symbol and colour so your view looks good. It may also be a good idea to reduce the symbol size (all done using the Legend Editor). Find the bore nearest the location 725000E, 6274000N. Which property does this bore belong to and what is the bore number (bores_ attribute)?

Hint: Make the bores and property themes active (hold down shift and click each theme name). Use the identify tool . Move the cursor until you are over the correct bore.

Turn on (tick) the tanks theme (point coverage) and move it to the top of the theme list in the view contents. If you wish you can again change the symbol and colour so your view looks good. It may also be a good idea to reduce the symbol size (all done using the Legend Editor). How many tanks are located within 10 kilometres of the above bore?

Hint: Make the bores theme active. Bring up the attribute table . Select the bore in question (i.e. select the record with the bores_ value you found above). Close the attribute table. Make tanks the active theme. From the main menu choose Theme - Select by Theme. Input the correct options from the drop down menus. Make sure you query the correct theme. Open the attribute table of tanks to see how many were selected. Once you have recorded your answer make sure to deselect all currently selected items by clicking button when each theme is active.

What are the land feature types (from landsys theme) in the property "Garnpang"?

Hint: Make the property theme active. Bring up the attribute table . Select the correct property. Click the button to zoom to the selected property. Make the landsys theme active. From the main menu choose Theme - Select by Theme. Input the correct options from the drop down menus. Make sure you query the correct theme. Open the attribute table of landsys to see which land features were selected.

Attribute Query
Display all land systems where soil type descriptions contain "S: SANDPLAINS" and vegetation type descriptions contain "V: abundant short grasses".

Hint: Make the landsys theme active. Use the Query Builder . Use wildcards (i.e. an asterisk "*") at the end of the description.

Create hardcopy output (i.e. print out) on the colour printer next to you. For this you will need to create a layout and use the following design rules:
a) Your map should contain land feature types with the selected polygons highlighted as yellow, roads and property boundaries.
b) You should have a title, legend, scale bar, north arrow and some descriptive text explaining what the map shows.
