Try out examples of what LuciadMobile has to offer
The samples are small applications that illustrate one or more functionalities of LuciadMobile. The samples are a good starting point to create your first LuciadMobile application, since you can combine and customize the demonstrated functionalities to suit the requirements of your application.
The all military symbols sample provides a graphical overview of all available military symbols.
You can change which symbology to display by selecting another symbology from the menu.
The Arrows sample illustrates the use of ELcdLineInterpolation and TLcdLineMarker
to create layers that contain arrows that are discretized as quadratic Bezier splines.
This sample starts with an empty layer and contains a menu item that allows creation of new arrows. The creation of arrows is performed by dragging a smooth curve. Arrows can be edited after a long-press on the arrow you want do edit.
The balloons sample illustrates the use of ALcdBalloonProvider
to define a completely custom balloon style.
In contrast to the default balloon style, the balloons in this sample are not center aligned but left aligned. This
sample also uses a custom nine patch background (res/drawable/balloon.9.png) to provide a different look for the balloons.
The Bitmap Icons sample illustrates the use of bitmaps and composite drawables to render icons.
In this sample a single TLcdFeatureLayer is created with 20 randomly distributed points.
The icons are drawn as bitmaps using the default BitmapDrawable provided by the Android
API. Selected points are drawn with a composite drawable that paints a circular gradient
underneath the selected icon.
You can select and deselect points by tapping the icons. To edit points, long-press an icon and select Edit Geometry from the pop-up menu.
The Common Operational Picture (COP) sample is an all-in-one sample demonstrating various functions of the LuciadMobile API. It consists of two main components: a client application and a server application.
The COP sample offers the following functionality:
Synchronization of data depends on an external server running the COP web services. A COP sync account must be defined in order for the sample to find this server. You can create a COP sync account under the 'Accounts' section of the 'Settings' application of your Android device.
The Custom Controllers Sample illustrates how you can implement and use controllers.
In this sample, a few custom controllers can be activated from the options menu. Three controllers can be used:
The Custom Data Format sample illustrates how to decode and display data stored in a custom format file.
This sample shows how you can decode a custom-format data file that describes flight plans and way points, and how you can display those data elements on top of a background layer. The sample also illustrates how you can label the data elements using balloons.
The File Loader sample illustrates how to load GeoPackage, LVDB, LRDB and KML files from the storage on a device. File will automatically be decoded and added to a map view.
The First Sample illustrates how to set up a basic application with the LuciadMobile API.
In this sample a background raster layer, representing the earth, and a single TLcdFeatureLayer with two
features (a polygon and a polyline) are created.
The shapes are styled with a default ALcdFeaturePainter. This painter
defines the basic styling settings, line and fill color for example, for features drawn in the features layer.
To select or deselect a feature, tap the feature. To edit a feature, long-press the feature and select Edit Geometry from the menu.
The GeoCanvas sample illustrates how to use the geocanvas to customize painting.
You can use the options menu to add new points.
The Geodesy sample illustrates how to use the geodesy API to perform distance, forward azimuth and interpolation calculations.
Move the two points of the line to change the measurements. The bottom panel displays the distance between the two points, the forward azimuth from one point to the other, and an interpolated point located halfway between the two points.
Sample to demonstrate decluttered labeling.
When starting the sample, it first shows the states of the U.S. with their abbreviated name as label. States with a high population have a higher chance of their name being painted. As you zoom in and more space is available, the full name of every state will become visible.
When zooming in even further, cities and rivers will also become visible. Cities with a high population have a larger point and label than cities with a low population.
This sample demonstrates how to paint decluttered labels for points, polylines and polygons. The sample uses three layers with vector data from the US. Each of these layers uses a separate painter that defines the specific styling that should be applied to the vector data.
To paint labels, every painter overrides the ALcdFeaturePainter#paintLabel method and uses
the ALcdLabelCanvas to paint labels. Depending on the properties of a feature, different styling
for both the label and its shape is applied.
Use the options menu to toggle the visibility of the different layers.
The Location sample uses the TLcdLocationManager to display a single point icon and its
coordinate at the current device (GPS) location. The sample also displays a circle, of which the radius indicates the
accuracy of the location measurement.
The Longitude-Latitude Grid sample illustrates the use of the TLcdGridLayer
to draw a longitude-latitude grid. The grid will dynamically adjust the size
between grid lines when the scale of the map changes.
The MGRS Grid illustrates the use of the TLcdGridLayer to draw an MGRS
for a specific UTM or UPS zone. It also uses a TextView to show
the most general MGRS coordinate for the area currently in view.
The military symbols sample illustrates how to create and draw military icons and shapes.
The sample contains some preconfigured military icons and shapes that are
distributed over the map. The military icons are points that are rendered
using an ALcdMilitaryIconSymbol drawable. To military shapes
are lines and areas that require an ALcdMilitaryShapeSymbol
as a style.
By long-pressing an icon or shape, the selected military symbol can be edited. To create a new military icon, choose the draw icon action from the options menu. Military shapes can be drawn by selecting draw graphic. A new activity will be started allowing you to choose the military symbol. Depending on whether you're drawing an icon or a shape, a different set of symbols will be available to choose from.
Note: In the symbol chooser, you can add new symbols by pressing the Add New button (star icon). You can also edit one of the listed symbols by long-pressing a symbol.
The Multi Map sample is an extension of the First Sample. It displays the map data in three separate
TLcdMapView instances.
The first map shows a regular map, the second one is rotated at 45 degrees, and the rotation of the third map is coupled with the onboard compass of the Android device. Each map displays the same shared content. If geometries are modified in one map, those changes will be displayed in the other maps as well.
The Orientation sample is an extension of the First Sample. It allows you to change the map's orientation policy from the options menu.
The following orientation policies are available:
The Raster Tile Sets sample illustrates the loading of various types of raster tile sets that are support by LuciadMobile. This includes:
Choosing LRDB will load an LRDB file from the sdcard of the device. The LRDB file in question contains a low resolution version of the NASA Blue Marble imagery combined with some higher resolution aerial imagery in the Los Angeles, USA region.
The Luciad Fusion option pops up a dialog allowing you to enter a URL referring to a Luciad Fusion server. After connecting to the server a list of available coverages will be presented. Choosing a coverage from the list will add a layer to the map displaying the coverage.
Selecting Bing Maps will connect to Microsofts Bing Maps server and display global high resolution aerial imagery. In order to access the Bing Maps servers you will have to enter a Bing Maps key. Your Bing Maps key can be entered in a dialog box or it can be placed in a file named bing-key.txt which should be placed on the SD card of your device in the folder MapData.
Choosing WMTS will pop up a dialog for the WMTS server URL. When pressing OK, the sample will retrieve the list of available WMTS layers from the server and display the subset of those that can be displayed by LuciadMobile. Choosing a WMTS layer name creates and adds a new layer to the map that displays the WMTS layer.
The Scale Dependent Icons sample illustrates the use of drawables to render different icons depending on the current view's scale. As you zoom in on the icons they will grow in size in discrete steps. When zoomed in far enough the dot icon changes to a bitmap icon.
In this sample a single TLcdFeatureLayer is created with 20 randomly distributed points.
To select and deselect points, tap the icons. To edit points, long-press an icon and select Edit Geometry from the pop-up menu.
The Shape Annotation sample illustrates how to annotate features interactively.
This sample is an extension of the Creation Sample. It allows the user to annotate features with a single text string. To create an annotation, long-press a feature and select Annotate from the pop-up menu. To view the annotation of a feature, tap the feature briefly. A balloon containing the annotation appears.
The Shape Creation sample illustrates how features can be created interactively.
In this sample, feature creation is initiated from the options menu. You can create either lines or areas:
This sample illustrates the use of a TLcdFeatureLayer
to display points as icons.
In this sample, a single TLcdFeatureLayer is created with randomly distributed points. Styling of the
points is performed using the default TLcdDrawableProvider. The icons are drawn as simple circular
disks using a custom Drawable implementation. Select or deselect points by tapping the
feature. Edit features by long-pressing an icon, and selecting Edit Geometry from the pop-up menu.
Sample to demonstrate the terrain analysis features such as terrain sampling and line-of-sight.
In this sample the green dot represents the user's location. The white objects are targets. Depending on which element you tap, a different LOS computation is executed.
TLcdLOSViewshedOperation.TLcdLOSPoint2PointOperation from the user to the point.TLcdLOSPoint2LineOperation from the user to the polyline.TLcdLOSLayer.
Use the options menu to change the accuracy setting of the LOS or to change the color map that is used for visualization. Points and lines can also be moved by long pressing on them and selecting the edit geometry option.
This sample also contains a TLcdRasterTileSetLayer layer to visualize elevation data
from an ALcdRasterTileSetModel. The elevation data is visualized using the default
TLcdElevationColorMap.
Sample to demonstrate how to consume a live track feed from a network service.
This sample shows track positions that are randomly generated by the COP web services. Tracks are displayed as airplane icons rotated according to their heading. Communication between client and server is via WebSockets.
This sample requires a server running the COP web services. A COP sync account must be defined in order for the sample to find the track server. You can create a COP sync account under the 'Accounts' section of the 'Settings' application of your Android device.
The View Decorator sample illustrates how you can add custom view decorations.
This sample shows four different types of decorations. You can activate a decoration type by selecting it from the options menu. The following decorations can be activated:
