 3D city models in the GIS field are evolving toward technological integration, infrastructure development, and deeper applications, becoming an important component of national strategic infrastructure. They are playing an increasingly significant role in areas such as urban planning and environmental protection. However, the primary challenge remains how to quickly generate building models. It is impractical to model each building individually — this would be too tedious, especially given the vast scale of cities and their continuous development, with new buildings constantly emerging. Is it possible to generate buildings in batches? To address this issue, the GISBox team has successfully implemented a feature in the GISBox scenario editor that allows users to select an area on the map and instantly convert it into building models. This functionality transforms vector data into realistic 3D building models, providing substantial support for GIS applications. This article will demo...

  The operation and maintenance of daily infrastructure—such as snow removal (in areas with frequent snowfall), garbage collection, road management, and water supply and sewerage system inspections—are often regarded as routine tasks that "naturally function as expected." However, in the face of demographic changes (such as population decline in some regions and labor migration leading to local manpower shortages), resource constraints, and climate change (with frequent extreme weather events affecting infrastructure stability), their maintenance is becoming increasingly challenging year by year. In such work settings, what role does Geographic Information System (GIS) actually play in practice? And what changes are lightweight GIS solutions like GISBox bringing about? Let's delve into this. Firstly, tasks like snow removal (in snowy areas) and garbage collection are highly "geographically dependent." Determining where snow accumulation is heavy, which roads sho...

 In the fields of 3D GIS and digital twin technology, the 3DTiles format has become one of the industry-standard data formats due to its outstanding performance. Proposed by the Cesium team, it is specifically designed for optimizing the visualization of large-scale 3D scenes, enabling rapid loading and smooth rendering of massive model data. Meanwhile, the PLY format, as a widely used 3D model storage format, is primarily employed for storing point cloud or polygon mesh data. To meet the demands for 3D data in cutting-edge fields such as digital twins and smart cities, efficiently converting PLY to the 3DTiles format is crucial. This article will analyze how to achieve this conversion using the GISBox software. I. PLY Format The PLY (Polygon File Format) is a 3D model file format developed by Stanford University for storing point cloud or polygon mesh data. It adopts a simple text or binary structure and supports attributes such as vertex coordinates, colors, and normals. It ...

 In fields like urban planning, logistics optimization, and environmental monitoring, GIS software has evolved into an essential tool for spatial data processing and analysis. User needs vary widely across different contexts: individual developers often prioritize open-source and free tools, enterprises focus on professional-grade capabilities, and project teams require efficient data transformation and collaboration features. Below are four GIS software options selected to address a range of requirements — from lightweight data handling to advanced spatial analytics. I. QGIS QGIS is a free, open‑source, cross‑platform GIS application with the following key strengths: Cost‑Free and Open Source: No licensing fees; its transparent source code allows for customization and community‑driven enhancements. Broad Format Compatibility: Supports nearly all common spatial data formats (e.g., Shapefile, GeoJSON, PostGIS) and can read many proprietary formats, including those from Esri. Extensi...

 WMTS (Web Map Tile Service) is an open standard web mapping service based on a RESTful architecture. It provides efficient map visualization by pre-generating and then clipping standardized map tiles (images) at different scales. This service uses a pyramid model to organize spatial data at multiple levels, enabling fast retrieval and loading. This significantly improves the transmission efficiency and rendering performance of large-scale geographic data in network environments, and is widely used in various online electronic map platforms and WebGIS applications. What is GeoJSON? GeoJSON is an open standard format based on JSON (JavaScript Object Notation), specifically tailored for encoding and exchanging geospatial data (such as points, lines, polygons, etc.). Standardized by the IETF (Internet Engineering Task Force) as RFC 7946, GeoJSON is widely used in web mapping development, geographic information systems (GIS), and data sharing due to its lightweight, readable, and ...

 In fields ranging from urban planning and logistics scheduling to environmental monitoring, GIS (Geographic Information System) software has evolved into an indispensable core tool for spatial data processing and analysis.

 In fields such as digital twins, smart parks, and urban planning, the integration of BIM (Building Information Modeling) and GIS (Geographic Information System) has become a core requirement. However, their core data formats have inherent differences: IFC, as the standard format for BIM, focuses on the attribute information, geometric relationships, and interaction logic of building components, and is often used for collaborative work during the design and construction phases; while 3DTiles, as the standard format for GIS 3D visualization under the OGC standard, excels at the efficient loading, layered rendering, and spatial overlay of large-scale 3D data, and is the core supported format of GIS platforms. II. Core Value of the Conversion 1. Solving “Information Silos”: Integrating detailed component information from BIM models into the geospatial framework of GIS, achieving a unified display of “internal building details + external geographical environment”; 2. Improving Visualiz...

In today’s rapidly developing Geographic Information Systems (GIS) landscape, the efficient processing and service publishing of image data has become a core concern in the industry. Image tile technology, as a key means to solve pain points such as slow loading and difficult transmission of large-scale image data, is increasingly demonstrating its application value. This article will elaborate on the definition, advantages, GISBox conversion tool, and practical steps of image tiles, providing WebGIS users with comprehensive technical references and practical guidance. I. What are Image Tiles? Image tiles are small blocks of image data in GIS, cut into fixed sizes (e.g., 256×256 pixels), organized through a multi-level pyramid structure to achieve fast loading and display. By pre-generating tile caches of different scales, it supports dynamic scaling and efficient rendering of map services and is commonly used in online map services. II. Advantages of Converting TIF Images to Image...

  Free on-premise cesium ion alternative WMS (Web Map Service) is an international standard protocol developed by the Open Geospatial Consortium (OGC). It defines how to request and retrieve dynamically generated map images (such as PNG, JPEG, or SVG formats) from geospatial databases over the Internet, rather than the map data itself. Users simply specify the desired map layer, spatial extent, coordinate system, and image size through a simple parameterized URL request, and the server will return the corresponding visual map. This allows geographic data from different sources and platforms to be shared, overlaid, and displayed in a unified manner, and is one of the core services for achieving geospatial data interoperability. What is GeoJSON? GeoJSON is an open standard format based on JSON (JavaScript Object Notation), specifically tailored for encoding and exchanging geospatial data (such as points, lines, polygons, etc.). Standardized by the IETF (Internet Engineering Task Forc...
