An effective disaster management is very important in order to lessen the impact of disaster. It defines into two phases, i.e. post-disaster and pre-disaster. Response is one of the important parts of the post-disaster phase. In order to provide the geospatial information about the disaster area, creating an innovative strategy and system can be an effective way to make a fast disaster response. In this research, a strategy to generate and display a photo-realistic 3D model through website is proposed in order to offer geospatial information about an area where was exposed by disaster. Nowadays, the advancement of web technology has caused a paradigm shift in the use of the website, especially for 3D contents. Web browsers have become effective platforms, as they are able to execute HTML5, JavaScript, WebGL, and OpenGL 3D graphics library that runs directly inside the browsers. WebODM (Open Drone Map) is an open-source cloud computational platform which is able to generate georeferenced maps, point clouds, elevation models and textured 3D models when user upload 2D UAV images into the WebODM. It provides some parameters that have significant changes over 3D model quality. After the user has upload all UAV images and setup the parameters, it will process the image through Structure-from-Motion method to obtain their interior and exterior orientation parameters. In 3D reconstruction phase, WebODM uses Patch-based Multi-View Stereo (PMVS) algorithm. PMVS is an image matching algorithm that uses a set of images as well as the camera parameters as inputs and then reconstructs the 3D model of an object or a scene that is visible in the images. The generated photo-realistic 3D texture model can be visualized in the CesiumJS website. It is an open-source JavaScript library for displaying world-wide 3D globes and maps. CesiumJS provide open standard format glTF as 3D model format. Generally, most 3D results are in OBJ format. Thus, the conversion from OBJ into glTF is necessary. The result of 3D texture model still has some holes on the occluded area, but the texture and color are well rendered. After that, CesiumJS will display the 3D model and some features about disaster management are integrated with the 3D model. It brings to the result that the combination between WebODM and CesiumJS would be a practical way to generate and visualize 3D model over Internet efficiently for disaster management purposes.
