During discussions in our GIS community chat, a colleague humorously noted: "After three years in 3D GIS, my most frequent projects are dashboards." This resonated widely among GIS developers, highlighting a common industry reality—dashboard projects dominate the WebGIS landscape. While not technically complex, these projects demand meticulous attention to aesthetic details like color schemes that consume disproportionate time.

Introducing BigDataView: An open-source repository of dashboard templates designed to alleviate this pain point.

Building on previous world map solutions—either officially approved but misaligned or precisely georeferenced but non-compliant—we present Amap's dataset that combines regulatory compliance, spatial accuracy, and practical usability.

When crafting dynamic marathon routes from official maps, directly tracing simplified route images is inefficient without proper spatial referencing. Georeferencing solves this by aligning raster images with real-world coordinates.

When processing DWG data in QGIS, exporting multiple layers individually becomes tedious. Here are three efficient batch export methods。

When asked about generating dynamic marathon route maps like those in Beijing Marathon 2024, I discovered MapPlus—a zero-code solution for creating animated race visualizations. This tool eliminates the need for custom development while producing professional-grade outputs.

In our previous article 《「GIS Data」Download Updated National Administrative Division Codes》, we discussed methods to acquire administrative codes. A common application is powering location selection components in frontend systems, as shown below:

When our frontend team requested updated administrative division codes, I leveraged the 2024 national standard vector map dataset (Approval No. GS(2024) 0650) shared in our previous article. This official dataset contains accurate administrative codes within its attribute tables, making it ideal for extraction.

Building upon our previous sharing of district/county-level administrative division data, we now provide the 2024 updated version sourced from China's official platform. This dataset addresses limitations in earlier versions (e.g., data gaps, insufficient detail) while maintaining cartographic compliance.

TorchGeo is a PyTorch domain library, similar to torchvision, specifically designed for geospatial data. It provides datasets, samplers, transforms, and pretrained models to help machine learning practitioners work with geospatial data and enable remote sensing experts to explore machine learning solutions.
