[OpenCV implements geometric transformation of images]
Article directory Summary: OpenCV implements geometric transformation, image thresholding and smoothing of images transform summary Summary: OpenCV implements geometric transformation, image thresholding and smoothing of images There are three important topics for image processing using the OpenCV library: geometric transformations, image thresholding, and image smoothing. In the geometric transformation section, the translation, rotation, scaling and […]
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 […]
21.4 Python uses GeoIP2 map positioning
GeoIP2 is an IP address location library that allows developers to find information about locations and geolocations based on IP addresses. It uses MaxMind‘s IP address database and provides a convenient Python API. GeoIP2 can be used for many different applications such as website analytics, ad targeting and authentication. GeoIP2 provides many different information, such […]
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 […]

Computational Geometry +2sat: 1020T3
http://cplusoj.com/d/senior/p/SS231019C We do this conversion Then 0/1 must choose one, and 2/3 must choose one. Then it becomes a 2sat problem If two triangles intersect, one can be selected and the other cannot be selected. One of the diagonal triangles is chosen and one is not chosen. One does not choose, one chooses The triangle […]
