Manual to Load Oblique Image Model

Overview

Oblique image model is becoming an important source of 3D GIS because it is precision, efficient, real, and cost effective. SuperMap GIS products support oblique image model. SuperMap iClient3D for WebGL can directly load oblique image model publishied by the server.

This document explains how WebGL Client load and browse oblique image data.

Operations

Here is an example to illustrate the steps.

1. Generate Configuration File

Introduction

You can generate a .scp format configuration file based on .osgb files from multiple folders. The configuration file records the relative paths, names, insert points, coordinate information, etc. of the oblique image model data.

If you already have the .scp format configuration file, you can skip this step to 2.Publish 3D Services.

Basic Steps

1 Open SuperMap iDesktop, go to Oblique Photogrametry > Create configure file.

2 In the dialog box that displays, as shown below:

3 Select the folder of OSGB models for Source Path

4 For Result Settings, please follow the suggestions below:

Target Path: The path to save the configuration file
Target File: The name of configuration file.

5 Set X, Y, Z for Reference Point. The default is (0, 0, 0).

Reference Point is the center of the oblique image mode. X represents longitude, Y represents latitude, Z represents elevation.

6 Check Projection Settings, set projection for the .scp file.

7 After settings, click OK to generate the configuration file.

Results

A new file with the extension of .scp will be generated at the specified target path, as shown below.

2. Publish 3D Services

Introduction

When you get the configuration file, you can publish the oblique image model.

Basic Steps

For details, please refer to Load Oblique Image Model with WebGL.

Results

1 Open SuperMap iDesktop, Workspace Manager>Scene>New Spherical Scene.

3 After loading data, save scene and workspace.

4 Start iserver via 4 startup.bat under %SuperMap iServer_HOME%/bin.

5 Start bowser, enter Web Manager via http://localhost:8090/iserver/manager. Quickly publish a service at Home Page.

When finished, click Finish and Close.

Results

The service displays in the service list http://localhost:8090/iserver/services, as shown below.

3 Browse Oblique Image Model at Client Side

Introduction

After publishing service, WebGL Client can load the oblique image data.

Please place WebGL package at %SuperMap iServer_HOME%/webapps.

Basic Steps

1 Get the url of the 3D data.

Enter http://localhost:8090/iserver/services and find the published 3D service.
Enter root directory page, click realspace.
Enter 3D page, click datas.
Enter datas page, click Config.
Enter data page, click Get 3D data configuration file to display the page as shown below, and copy the url address.

2 Enter the path of WebGL product package in %SuperMap iServer_HOME%/webapps, in the examples folder, open S3MTiles.html with text editor, and modify the following content.

Fig. Change parameter

Modify the scene. addS3MTilesLayerByScp () function, and change the address to the copied address, and change the name.
Modify the Cesium.Cartesian3.fromDegrees() function. The parameters of this function are longitude, latitude, elevation of the center point of the model. Please modify the insert point in the scp file, which is used to fly to the position of the oblique image model.

3 Open the S3MTiles.html page, that is, enter the url http://localhost:8090/%WebGL Package%/examples/S3MTiles.html in the browser.

Results

After you open the page, the camera flies to the position of the oblique image data, as shown below.
