Build Your Own Map



Key Concepts

In NIMAMUSE, the process of building your own map is centered on the NIMAMUSEapplication called Fusion. Fusion requires that input data coveringyour area of interest be accessed and prepared by NIMAMUSE support applicationsRaster Importer (rast_imp) and Vector Importer (vpf_imp). Fusionthen crafts this imported data into a map, and the output from Fusion canbe displayed immediately, printed immediately, and saved to a file in manypopular formats.

Fusion produces digital maps by fusing vector and raster map data. A singleraster map serves as a base, while user-selected vector features are overlaidon this base. User-designed annotation can also be laid on the constructedmap. After all layers of the map are assembled and crafted to a desiredappearance, Fusion freezes the layers together into a new, single rastermap object (your new custom-made map) that can be printed, that can be savedto a file to be distributed, or that can be saved to a file to be used asinput to one of many applications.



Custom maps are built from multiple layers of map information using Fusion.To have a meaningful map, these layers (Raster Base Map, Vector Overlays,and the Annotation Overlay) must represent the same geographic area. Theselayers are individually obtained by using the NIMAMUSE support applicationsRaster Importer and Vector Importer, and judicious use of these importersis required in order for Fusion to precisely align these layers together.This precise alignment of layers of cartographic data is calledregistration.


Reasons to Build Your Own Map

Analysis of Your Area of Interest in NIMAMUSE.  By building yourown map, you can select and display just the features that you are interestedin. In Fusion, there is always an instantaneous readout of latitude and longitudeof any point. There is also basic mensuration in a Fusion display: distance,azimuth, and area.

Use as a Base Map in NIMAMUSE.  Fusion is used to built the basemap element for two internal NIMAMUSE specialty applications: PerspectiveScene and Line of Sight.

Perspective Scene (pscene) builds "from the cockpit window" views of mapdata. Refer to the Perspective Scene page(PSCENE.DOC).

Line Of Sight (los) provides terrain analysis for ground based operations.Refer to the Line of Sight page (LOS.DOC).

Use as a Base Map in other Applications.  NIMAMUSE will outputa Fusion constructed map in many popular formats for ingestion by many popularcommercial geographic information and presentation software packages, aswell as by custom-built software systems.

Produce Paper Maps.  NIMAMUSE has the capability to immediatelyprint any map constructed in Fusion.


How to Build Your Own Map

There are three major steps involved in building your own map usingNIMAMUSE:

The flow of data in the map building process is illustrated in thisdiagram:





1. Access & Prepare NIMA Digital Data

As the diagram above shows, the NIMA Digital Data you use as input must firstbe identified, accessed and prepared for input into Fusion. This is donewith the NIMAMUSE support applications Raster Importer and Vector Importer.Both of these applications allow you to identify and define exact piecesof raster chart data and vector feature data for eventual layering togetherin Fusion. Follow the links below for explicit instructions on using theRaster Importer and the Vector Importer.

2. Fusion

Fusion is one of the major applications in NIMAMUSE. Fusion allows you toselect certain types of map information and present it in a manner you choose.The focus of Fusion is the building of individual layers of data, and thenoutputting those layers as a single map object, readable by many popularcommercial products.

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.


3. Output in Fusion

After you have crafted your multiple inputs into a single map object usingFusion, you can save your new map object in two basic ways: you can savethis map in Fusion's native "Map Document" format, which is readable by Fusion,and preserves the separation of the individual layers and all of the informationin the layers of your map; or you can output your map built in Fusion asa group of pixels in a single raster file. This single raster file can beoutput in the NIMAMUSE raster format for further use in the NIMAMUSE applicationsLine of Sight andPerspective Scene. This single rasterfile can also be output in any of a number of standard formats, making itreadable by many popular commercial software products. . However, the vectorfeatures and annotations that you made are no longer individually accessibleonce Fusion "fuses" all of your layers into one map object.
