My business scenario: You need to use html2canvas to download the map drawn by Openlayers. Expectation: Can be downloaded as images or even other formats (svg) files. Result: The download is a blank image. Troubleshooting errors: The request data is echoed to the page normally. When intercepted using html2canvas, cross-domain will occur, resulting in the […]

Implementing batch release of GeoServer vector files based on Python
0. Preface Due to the large number of vector layer files, manual publishing is time-consuming and laborious. The geoserver package (geoserver-restconfig) supported by Python is also in disrepair and cannot be used normally in newer geoserver versions. After consulting a lot of information and referring to the following blog, I simply wrote a code to […]
geoserver automatically publishes vector data: RUST API
Foreword I recently studied the geoserver rust api, and the official documentation is relatively simple and not detailed. This article describes the python code implementation of using the geoserver rust api to publish shapfile data on the official documentation webpage. Among them, there is a warehouse geoserver-rust that implements a large number of geoserver’s rust […]
Application Utility – Reading geospatial raster files using GDAL OpenCV v4.8.0
Previous tutorial: Adding a track bar to our application Next tutorial: Video input using OpenCV and similarity measurement Original author Marvin Smith Compatibility OpenCV >= 3.0 Geospatial raster data is a product heavily used in geographic information systems and photogrammetry. Raster data can often represent images and digital elevation models (DEMs). The standard library for […]

Leveraging geospatial data in Python with GeoPandas
The true potential of spatial data lies in its ability to connect data points and their respective locations, creating endless possibilities for advanced analytics. Geospatial data science is an emerging field in data science that aims to leverage geospatial information and extract valuable insights through spatial algorithms and advanced techniques such as machine learning or […]
ABAQUS geostress balance script (source code) – automatic repeated import into odb method
This code can implement the cycle of ABAQUSautomatically creating a job — importing the odb file of the previous job as the initial stress field — submitting the calculation job —— creating a new job . The number of cycles can be set by yourself. The method of use is to copy the .py file […]

Geoserver configuration based on Jetty9 https certificate
1. Environment preparation Since the jetty version that comes with Geoserver does not have the https module, you need to download the full version of jetty. Here you need to first check the jetty version corresponding to the local geoserver, enter the geoserver installation directory, and execute the following command. java -jar start.jar –version Jetty […]
