3 Overview The SkylineGlobe 3D Web Application is a powerful application made available in the SkylineGlobe Web Package for navigation, viewing, analysis and editing of high resolution 3D landscapes created with the SkylineGlobe products. Website users can overlay the terrain with basic objects, imagery layers and feature layers (in.fly,.shp, or.kml/.kmz formats), as well as analyze the terrain using a powerful set of measurement and terrain analysis tools. Extended capabilities are automatically available to users with TerraExplorer Plus and TerraExplorer Pro installed on their system. TerraExplorer Plus users can import feature and raster layers as well as fully textured urban model databases (3DML), while Pro users can further enhance the photo-realism of their 3D view by also adding advanced objects like buildings, dynamic objects, video, and terrain modification objects. Both TerraExplorer Plus and Pro users can connect to and load sources from TerraCatalog, a catalog database that helps you access, manage and organize your raster, feature, projects and other geographic assets. Additional features available to TerraExplorer Plus users include: Extended feature layer support. Import and editing of raster layers. Import and editing of 3D mesh layers. Interactive drawing tools to overlay and edit all 2D and 3D objects. Access to TerraCatalog, a catalog database that helps you access, manage and organize your raster, feature, projects and other geographic assets. Features available to TerraExplorer Pro users include all Plus features and the following: Feature layer editing. Tool for publishing project kits. Interactive drawing tools to overlay and edit advanced objects (Building, Video on Terrain, Terrain Modification, Hole on Terrain and Dynamic Objects). 3

4 Extended Feature Layer Support and Editing SkylineGlobe Advanced Capabilities TerraExplorer Plus and Pro users can load all feature layers in supported formats, (e.g. Esri shapefiles, Microsoft Access, DXF, DGN, MapInfo) and from supported servers (e.g. WFS, TerraCatalog, Skyline Feature Server, ArcSDE, Oracle). Layer level operations can then be performed using the layer s property sheet Pro users can also perform advanced feature layer editing. The Attribute Table enables you to search the layer attribute database files and display the results in the 3D Window. You can use this table to fine-tune the information that is displayed on the terrain or to create a new project layer or file based on the filtered layer. The original layer is not modified. Spatial Queries - Features can also be selected based on their spatial relationship with a drawn polygon, line or point, or with an existing object. You choose whether to include only features that entirely overlap with your selected or drawn geometry, or whether to include also those that partially intersect. You also can define a buffer zone to include features within a certain radius of the selection. Selected features can then be merged into a single feature, clipped one from another, deleted, or exported to a new file. Spatial Query Various spatial operations can be performed on the selected features, including deleting selected features, merging features into a single feature, creating a multipart feature, clipping one polygon from another, exploding a multi-part feature into its individual component features, and exporting selected features to a new file. Saving: Since you are always connected to the data source (local or remote), you can easily get the latest source updates by refreshing the layer. For.shp files and SFS/WFS-T (A WFS service with read-write access by enabling transactions), all changes can be saved directly to the original source file. Data source updating is also allowed for streaming layers. 4

5 Import and Editing of Raster Layers TerraExplorer Plus and Pro users can overlay the terrain with imagery layers containing geo-referenced, satellite or aerial images and replace the elevation data of the terrain database with geo-referenced elevation raster. Raster layers can be loaded in supported formats (e.g.,.jpg,.ecw,.img,.bmp) and from supported servers (e.g. WMS, Oracle Spatial, TerraGate, ArcSDE). Raster layer properties can then be set in the layer s property sheet. Imported data, of unlimited size and resolution, is automatically morphed with the terrain imagery. SkylineGlobe for TerraExplorer Plus Users Imagery Layers An imagery layer is a geo-referenced, satellite or aerial image that overlays the terrain imagery. The imagery layer feature enables the user to add unlimited size, geo-referenced, satellite and aerial images directly to a TerraExplorer project. A source file that has multiple resolution levels (e.g., Skyline MPU, MrSID, etc.) is visible from any altitude. The layer can be of better resolution than the area on which it is placed. Automatic morphing between the terrain imagery and the imagery layer is performed. Projection: If the source file is not rectified to the same coordinate system as the terrain coordinate system that the TerraExplorer uses, the user can reproject it on-the-fly using the built in mechanism. Clip Polygon: A subsection of a raster file can be displayed by loading a Shape file containing the required clip polygon. SkylineGlobe supports the following imagery layer file types and servers: Skyline Image MPU (.Ii.mpu) Windows Bitmap (.bmp) ER-Mapper (.ecw) ER-Mapper Jpeg2000 (.jp2,.j2k, jpc) Gdal formats (Gif, Ntf, Jpeg, Tiff, Img, Cib) Gdal Jpeg2000 (.jp2,.j2k,.jpc) HTC raster file (.htc) Mip Terrain (mpt) Web Map Server (WMS) Oracle Spatial Database ArcSDE Raster Server ECW Image Web Server TerraGate Server (.tgate) Web Catalog Service (CS-W) TerraCatalog 5

6 Image MPU (.li.mpu) MrSid (.sid) Erdas Imagine (.img) NGA formats (.CIB,.CADRG,.ADRG,) Tile Text file (.tlt) Projection Text file (.prj) Tiff Format (.tif) Local Skyline terrain database (.MPT) Elevation Layers An elevation layer is a geo-referenced elevation raster that replaces the elevation data of the terrain database. The elevation layer feature enables the user to add unlimited size, geo-referenced elevation data directly to a TerraExplorer project. The file can be of better resolution than the area on which it is placed. Automatic morphing between the terrain imagery and the imagery layer is performed. A source file that has multiple resolution levels (e.g., Skyline MPU, WMS etc.) is visible from higher altitudes. Projection: If the source file is not rectified to the same coordinate system as the terrain coordinate system that the TerraExplorer uses, the user can reproject it on-the-fly using the built in mechanism. SkylineGlobe supports the following elevation layer file types and servers: Window Bitmap (.bmp) ER-Mapper (.ecw) Gdal formats (Tiff, Img, Arc/Info Binary Grid, USGS SDTSDem, USGS ASCii Dem, Dted) Erdas Imagine (.img) Mip Terrain (.mpt) Elevation MPU (.Ei.mpu) NGA DTED (DMED) No Stream formats (Bitmap, Jpeg, Gif) Tiff (.tif) TiLe Text file (.tlt) Projection Text file (.prj) Skyline TerraGate Server Web Map Server (WMS) Oracle Spatial Database ArcSDE Raster Server ECW Image Web Server Web Catalog Service (CS-W) Import and Editing of 3D Mesh Layers (3DML) A 3D mesh layer (3DML) is a fully textured urban model that has been compressed and stream-optimized to accelerate loading speed and efficiently handle memory. 3DMLs are created in TerraBuilder CityBuilder by merging 3D mesh models generated by TerraBuilder PhotoMesh and/or layers with individually referenced 3D models. These photo-realistic, geographically accurate, and stream-optimized databases can be included in local TerraExplorer projects or published to remote clients via TerraGate. SkylineGlobe constructs a 3DML layer as a layer object, which is then displayed in the Project Tree. After loading the layer from file or server, you can set its appearance and parameters in the layer s property sheet. Streaming: 3DML layers can be loaded from 3DML files on your own computer or local network or from a database that is served over a network by the TerraGate SFS service. Styling: When a 3DML layer is loaded, it is read and put in the Project Tree as a 3DML Object that contains each of the feature layers which was merged in creating it. This layer object enables you to perform layer level operations by using the property sheet to set the appearance and behaviors of the features contained within the layer. 6

7 Spatial Queries: Various spatial queries can be performed on the 3DML s feature layers, to select features within a particular geographical area. Using the Attribute Table Took, the layer attribute database files can be searched to easily edit the attribute values of multiple features and to create a new shapefile based on the filtered data. Saving: Layer changes can be saved to the original shapefile or to a new shapefile. 7

8 Publishing Project Kits TerraExplorer Pro users can create a kit for an entire online project or for a subset of an online project to use offline in disconnected environments, and to share with external users. When creating an offline project in a specific area, all project terrain, data, and objects are included in your mini-project so that you can view and display your area of interest comprehensively and accurately in a fraction of the time required to create an entire project. SGWP also offers the option to publish local and Internet kits. Publish Offline Project in Area 8

9 Advanced Objects TerraExplorer Plus and Pro users can create complex 3D visualizations by adding to their project: 2D Objects - Text Labels, Image Labels, Polylines, Polygons, Rectangles, Regular Polygons, 2D Arrows, Circles, Ellipses, Arcs 3D Objects Buildings, 3D Polygons, Boxes, Cylinders, Spheres, Cones, Pyramids, 3D Arrows. After creating objects, the user can edit single or multiple objects parameters using the properties sheet, edit objects directly in the 3D window, and copy /move/delete objects in the 3D window. The objects are organized in the Project Tree. TerraExplorer Pro users can further enhance the photo-realism of their 3D view by adding: 3D models - Load pre-prepared models, such as buildings and billboards, and place them anywhere on the terrain. Models can be loaded in a variety of formats, including Collada, Direct X, 3DS, OpenFlight, and then optimized by conversion to XPL2 to improve overall model display performance as well as download rate. Building objects - Add 3D buildings to the project by manually defining the geometry of the building rooftop and stretching it above the basic terrain, or by importing the rooftop geometry from external feature layers. Dynamic objects Easily add movement to 3D objects. The object s route is set by manually placing waypoints in the 3D Window. Terrain objects Modify the elevation values of the terrain or cut a hole in the terrain based on a polygon s shape and elevation. Video file on the terrain - Play a video file either on a selected area of the terrain (Video On Terrain), or on a floating billboard. Point cloud models - Add a pre-processed point cloud model at any point in the 3D terrain. These models are created from a list of points in a 3D area that are collected by various 3D scanners. You can also add a pre-processed point cloud model set. These sets are created from lists of points in a 3D area that are collected by various 3D scanners, and GPS route reading of the collecting instrument s movement while scanning the data. Draw Tab 9

10 Importing 3D Models The 3D model feature allows you to place a pre-prepared 3D object at any point in the 3D terrain. These models can be created using external design tools. Models can be loaded in any of the following formats: Collada (DAE) Direct X (X) and its compressed version (XPC) 3DS - 3D studio format for exchanging 3D data models OpenFlight (FLT) Multigen format for exchanging 3D data models and its compressed version (FPC) XPL and XPL2, which provide better performance for the Direct X model (A set of XPL files is created from a single X file where each file contains data for one Level of Detail (LOD) only) All model formats support BMP, JPG, DDS, and PNG texture formats. FLT also supports Silicon Graphics popular texture formats (RGB, RGBA, INT, INTA, BW). All loaded models can be optimized by conversion to XPL2, either by using the MakeXPL tool or automatically during the publishing process. When a model file is converted to XPL, a set of XPL files is created from a single X file where each file contains data for one Level of Detail (LOD) only. TerraExplorer displays the best LOD file based on the viewer position in relation to the object. When downloaded from a web server, each file is also downloaded independently. This results in an improvement in overall model display performance as well as download rate. 3D Models 10

11 Building Objects The Building feature allows you to add 3D models to the project by manually defining the geometry of the building rooftop and stretching it above the basic terrain, or by importing the rooftop geometry from external feature layers. You can define the shape of the roof as a flat surface, or as an angular surface. After defining the building geometry, you can assign fill color and texture from external files, or apply texture from the terrain to the roof and side walls. Dynamic Objects Easily add movement to 3D objects. In addition to the featured set of ground and air vehicles, Pro and Plus users can upload any 3D model file. The object s route is set by manually placing waypoints in the 3D View. There are two types of dynamic objects: Ground Vehicle: Get pitch and roll angles according to the terrain surface under the object while it moves. Air Vehicle: Get pitch and roll angles according to the altitude differences between the waypoints, regardless of the terrain surface. Terrain Objects The user can add objects that affect the terrain model, either modifying the terrain or creating holes in the terrain. Modify Terrain Tool: Changes the elevation values of the terrain based on a polygon. The surface of the terrain is raised or lowered according to the elevation values of the polygon's points. Different elevation behaviors allow replacing or cropping above/ below the original values of the terrain. The interior of the polygon can be flat or irregular in shape. Modify Terrain Tool Hole on Terrain: Cuts holes in the terrain based on a polygon that exposes the other side of the terrain through the opening. 11

12 Video on Terrain Live or recorded video streams can be displayed in their correct geographic context by importing a video file into TerraExplorer. The video can be stationary or move on the terrain based on telemetry data. Projection options include Video on Terrain in which the video file is projected on the terrain, and Video Billboard, in which the video is projected on a floating billboard. Like other objects that can be added to the terrain, video objects are saved with the TerraExplorer project along with their defined properties including field of view, projection distance, and projector color and size. When a video is being projected on one specific area of the terrain, the video projector and projection can be positioned using the video property sheet and the 3D Window. When the camera is moving across the terrain (e.g. video from UAV), telemetry data is used to synchronize the video frames with their corresponding locations. Telemetry data can take either of the following forms: File-based A separate comma-delimited text file holds location parameters for the video frames. Integrated digital encoding of metadata KLV (Key-Length-Value), a data encoding standard, is used to embed location information in the video feeds. Items are encoded into Key-Length-Value triplets, where key identifies the data, length specifies the data's length, and value is the data itself. Integrated KLV data can be used for real time streaming, in addition to pre-recorded movies. Supported video file formats are determined by the codecs that are installed and registered on your computer. Most files that Windows Media Player can play (e.g., *.avi, *.mpg, etc.), including streaming Microsoft Media Server (MMS) content, can be draped on the terrain. TerraExplorer can also use RTSP, or any custom protocol using video:myprotocol:// for any custom protocol that is defined on your system: e.g. video:custom1://. Display Live Video on Terrain 12

13 Point Cloud Models The Point Cloud model allows you to add a pre-processed point cloud model at any point in the 3D terrain. These models are created from a list of points in a 3D area that are collected by various 3D scanners. The import Point Cloud feature supports Skyline s proprietary Point Cloud files (CPT). The Import Linear Point Cloud Set allows you to add a pre-processed point cloud model set. These sets are created from lists of points in a 3D area that are collected by various 3D scanners, and GPS route reading of the collecting instrument s movement while scanning the data. Timespans Timespans can be set for groups and objects, limiting the display of the object or group on the terrain to the specified start and end time values integrated in the object or group s property sheet. The project s time and date are adjusted using the time slider. API Development SkylineGlobe Application Programming Interface (SGAPI) Extend your application by developing your own JavaScript or HTML tools, which use the SkylineGlobe Application Programming Interface (SGAPI). The SkylineGlobe Application Programming Interface (SGAPI) provides the properties and methods to create tools to execute and manage SkylineGlobe tools and panels (e.g. Favorites, Project Tree, Results, and Search). SGFramework is the entry point to all SkylineGlobe classes. Through this class you can customize the different components of your web application as well as access all the properties and methods of the TerraExplorer v65 API. The following classes are properties of the SGFramework class: Favorites - Provides methods for adding and removing any object or location to/from the SkylineGlobe Favorites panel.

14 TerraExplorer API The TerraExplorer Application Programming Interface (API) provides a powerful way for integrating SkylineGlobe and custom applications. It also provides a way to create extensions that can access external information sources such as databases or geospatial files. The following main issues are addressed by the TerraExplorer API: Navigating in the 3D world. Project management (e.g. creating extensions to add support for additional file and database formats). Feature and raster layers (e.g. editing of feature layers) Object management (e.g. real-time movement of objects for command and control applications or addition of custom-made objects). Terrain analysis (e.g. advanced terrain queries such as terrain profile). Event notifications. In addition, TerraExplorer's API allows a variety of other operations such as controlling the content of the containers, querying the terrain for height information, taking snapshots, controlling the mouse and more. ISGWorld is the main entry point to most TerraExplorer interfaces. Through this interface you can manage your application and 3D content and handle events. The following interfaces are properties of the ISGWorld interface: IProject65 (.Project) Open the project, manage its properties and save the project. INavigate65 (.Navigate) Navigate in the 3D world by setting the camera position and produce complex movements such as FlyTo and Zoom in and out. IProjectTree65 (.ProjectTree) - Provides complete access to the TerraExplorer Project Tree. It allows the creation of groups and queries on objects in the tree.

ICommand65 (.Command) Enable activation of TerraExplorer user interface operations such as turning on and off the underground mode or start manual object editing. ICoordServices65 (.CoordServices) Coordinate system related features. It allows you to define a coordinate system for your input coordinates, and have TerraExplorer convert them to the coordinate system of the current terrain database. Events Listen to TerraExplorer events using the AttachEvent method. See for an API reference guide. 14

15 TerraCatalog TerraCatalog is a catalog database that helps you access, manage and organize your raster, feature, projects and other geographic assets. It catalogues raster, feature, and project information, maintaining detailed information including type, dimension, dates, tags, metadata, and custom data. You can easily search and find the standard geographical data you require for a project, using various text and geographic properties. TerraCatalog enables you to do all the following: Work collaboratively, contributing all updates to a common repository. Automatically scan and catalog entire folders. Store connections to various data sources. Publish selective parts of your catalog to Web Catalog Service (CS-W). Note: TerraGate Web Catalog Service (CS-W) provides TerraCatalog search interface for remote users, so that imagery and elevation data that is stored on files and in remote databases can be easily searched and located using TerraCatalog. TerraCatalog s data sources can be located on a local disk, on the network, on Oracle or on an SQL Server. Sharing Information SkylineGlobe enables you to freely share the unique 3D worlds you create with all or specific users in your organization, by publishing projects and project data on a SkylineGlobe server. You choose precisely what content to share and with whom to share it. Those individuals can then view that content with the free SkylineGlobe web application. Collaborate on a project with other Skyline users using the Community tool to chat, jointly annotate the terrain, and synchronize flight. 15
