Fusion is one of the major applications in NIMAMUSE. Fusion allows you toselect certain types of graphic and textual map information and present itin a manner you choose. The focus of Fusion is the building of individuallayers of data, and then outputting those layers as a single map object,readable by many popular commercial products.
Fusion produces digital maps by fusing vector and raster map data layerstogether. A single raster map serves as a base layer, while user-selectedvector features in other layers are overlaid on this base. A user-designedannotation layer can also be laid on the constructed map. After all layersof the map are assembled and crafted to a desired appearance, Fusion freezesthe layers together into a new, single raster map object (your new custom-mademap) that can be printed, that can be saved to a file to be distributed,or that can be saved to a file to be used as input to one of manyapplications.
Typically, a raster base layer is chosen first, with one or more layers ofvector map data overlaid next, followed by a layer of user-defined annotations(your custom map data). Since these layers are always visible while beingconstructed in Fusion, you can continually refine the appearance of the displayedmap layers. You can refine the appearance of the vector data by the orderingof the layers. You can also refine the appearance by choosing any color,line weight, and shading of the vector objects. You can choose to includeonly certain features in the vector layers.
Once you are satisfied with the final appearance of your multi-layered mapobject, you can perform some analysis of this area while still in Fusion.You can choose to view the latitude and longitude of the cursor in the mapwindow, and you can also perform measurements on your map such as distance,azimuth, and area calculation.
Fusion Input and Output
After you have crafted your multiple inputs into a single map object usingFusion, you can save your new map object in two basic ways:
First, you can save this map in Fusion's native "Map Document" format, whichis readable by Fusion. This format preserves the separation of the individuallayers and all of the information in the layers of your map for furtherrefinement and analysis by any machine running Fusion. These Map Documentsare saved to files with a " *.map" extension.
Second, you can output your map built in Fusion as a group of pixels in asingle raster file. This single raster file can be output in the NIMAMUSEraster format (*.ima) for further use in the NIMAMUSE applications "Lineof Sight" and "Perspective Scene". This single raster file can also be outputin the standard formats TIFF (*.tif) and BMP (*.bmp), making it readableby many popular commercial software products. However, since all of yourlayers are now fused together into one single map object in a raster file,the vector features and annotations that you made are no longer individuallyaccessible or editable by these commercial products or by Fusion.
The following tables illustrate the breadth of both input and output inFusion:
Some Fusion Session Windows
In the sections that follow, some of the more common Fusion windows willbe presented to illustrate basic Fusion functionality of input, output, andmap layer definition. Also, there are nine Fusion tutorials in Section 1of the Fusion User's Guide, FUS_UG.DOC. Refer to this Fusion User's Guide towork through these highly recommended tutorials. Fusion has many optionsbeyond the basic functions presented here, and you are encouraged to explorethose options and features on your own.
Here are some sample Fusion session windows from where you will build yourcustom-made map:
The raster basemap is loaded first during a typical Fusion session. Hereis an empty map window with the "Raster Background" choices displayed fromthe "Data" pulldown:
(Note that having no raster basemap is a valid choice. You have more freedomto change projections with no raster basemap.)
The next step would be to load and symbolize you vector data. This data youhave already prepared with the NIMAMUSE Vector Importer (vpf_imp). The followingwindow shows the command to add vector data as the pulldown "Data/OverlayFiles.../Add...".
You will then be presented with a file selection box to identify your vectorfile(s). These vector files have the extension " *.vec":
Once the vector files have been loaded you can change their symbology andcolor. Here is a small example from Tutorial 3 which shows roads and populatedareas as vector data overlaid on raster basemap CADRG at Norfolk, VA. Althoughthis page is shades of gray, you can see the thick lined roads and the hatchuredwhite area of the populated place features:
You can also change raster basemaps during your Fusion session. Compare thefollowing map using CAC with the previous map using ADRG (note that the vectorportrayals did not change):
Changing the Appearance of Vector Data
Choosing the "Data/Overlay Files.../Modify..." from the main pulldown menugives you the "Vector Overlay List" window shown below. This is where youcan change symbology, color, and layer order. Clicking the "X-box" in theDisplay column turns on the display of that theme, clicking on the symbolin the Symbol column brings up the second window shown below, and highlightinga row and click "UP" and "DOWN" rearranges the layer order.
The "VPF Symbol Selection" window lets you choose from many available symbolsand colors. Note that only the applicable feature type (either point, line,area or text) is active.
Drawing Tool Bar
Drawing tools for hand placement of text andvector annotations in a vectorlayer are presented in a toolbar near the top of the standard map window:
These are the functions associated with each button shown above from leftto right:
- Insert a Point Feature
- Insert a Text Feature
- Insert a Line Feature
- Insert a Polygon Line Feature
- Insert a Rectangle Feature
- Insert a Range Ring Feature
- Selection Tool
- Line Aggregation
- Ring Aggregation
- Edit Current Symbology
- Measure Tool (distance, volume and area calculations)
- Spatial Query (on attributes of VPF features)
- Anchor Tool (computes range and bearing)
- Assigns Tool Functionality to Annotation Layer
- Assigns Tool Functionality to the ODBC Query Layer
- Drawing Toolbar Help
Tutorial 5 in the Fusion Users Guide willstep you through these toolbar functions.
New to the NIMAMUSE 2.1 version of Fusion is the ability to determine VPFattributes from the VPF vector data that you put in a vector layer. Thisworks just like VPFView, which is also on the NIMAMUSE 2.1 release.
First click on the Spatial Query button on the Drawing Tool Bar, which isthe button with the exclamation point " ! " on it. Then, using thecursor, click on any VPF feature portrayed in your window. As an examplein the window below, Populated Places point features are shown as smallplus-signs:
A text window (like the second window shown below) will appear with thatfeature's VPF attributes:
As mentioned before, your custom-made map can be saved as a Fusion Map Document( *.map ), or as a raster file ( *.bmp, *.ima, *.tif ).
The window below shows the "Save As..." function on the "File" pulldown.This is where you would save your work as a Map Document. Remember, Map Documentscan be read in later by Fusion and all of the layers will still be accessiblefor modification.
The window below shows the " Data/Export Map Image " function. This choicewill save your work as a raster file. You then further choose "As BMP...","As NIMAMUSE raster...", or "As TIFF..." to select one of the three rasterfile types available:
As mentioned before, it is highly recommended that you work throughthe hands-on tutorials in the Fusion UsersGuide, FUS_UG.DOC . A favorite approach is to print out the tutorialson paper first before doing them.
