How BHSoft utilized Cesium and Leaflet for a drone-based building inspection application

The key technologies of the application and why BHSoft chose them This is a multiplatform drone-based building inspection application that can examine buildings fast, efficient and automatedly. The application uses the images and data collected from drones to display 3D models, draw buildings, and provide many different machine learning-powered functions. BHSOFT helped our client build the application to perform both primary functions: controlling the drones to take images; and processing the images to display the 3D model, draw buildings, and make related reports. With years of experience in working with GIS-related as well as 3D projects, we completed this project with no major difficulties. For this project, we built three […]

Understanding vector tiles

In 2D GIS (Geographic Information System) world, vector tile is an important concept for mapping. This article will introduce to you the general definition of vector tile and the reason why it is the next generation of tiled maps. Introduction to vector tiles People have been familiar with the raster tile concept. With raster tile, the map is illustrated by a set of squared images placed next to each other, each with a fixed geographical area and scale. Vector tiles, which were introduced later also divide data into square. The difference is that there is no raster image, instead, pre-generated vector data are present on the requested area. These vector […]
