About this plug-in

Although it is a vector tile that is in the popular stage such as being planned to be natively supported by QGIS 3.14, the "Geographical Survey Map" of the Geographical Survey Institute, which is one of the most valuable data in Japan, is also provided [Geographical Survey Map Vector (tentative name)) Vector tiles are available as Experiment. You can also read vector tiles with Vector Tiles Reader introduced earlier, but it is dedicated to Geographical Survey tiles so that you can easily obtain vector data with a simple UI. I created a plug-in "GSI-VT Downloader".

Operating environment

--Developed with QGIS 3.10. --Works on both macOS and Windows

Plugin installation

It is not yet listed in the official QGIS repository, so please download the zip file from the above GitHub repository and install it manually.

You can select either "Run in rectangular area" or "Run in display area".

A vector layer will be added to the map as soon as the data download / conversion is complete.

important point

――The wider the target area or the higher the zoom level, the more tiles and data required, and the longer it takes to download.
