Visualize elevation of any area on the map with filled area charts also known as a ridge line.
QGIS 3 plugin that is meant for adding globe visualization to the current map.
The plugin is still in beta-development. Please report issues preferably to Issues.
Developed by Gispo Ltd.
Nuclear Energy Plant Radiation Plugin
This project was developed on the course of the Geographic Information System (GIS) of the master’s degree program in data science at the University of Salerno. The goal of this project was develop a python plugin for the software Quantum GIS (QGIS) in order to visualize on the open street map all nuclear energy plant in the world. This plugin use the mqtt protocol for receive of radiation data from sensors in order to dinamically visualize it on the map. In order to clarify the visualization of the radiation data, a heat map was created and used. The plugin uses fake radiation, it simulates that the data comes from real sensors.
It is a simple cutting tool (in slices) of DEM data, to draw pretty postcards, for lovers of reliefs.
The principle is to build a series of altitude profiles (lines or polygons), to juxtapose them to give the illusion of a 3D view. Here, no calculation of the atmospheric refractive index, no consideration of the Earth’s curvature … just a little geometry, and the styles do the rest. The resulting layers are positioned where you want, the coordinate system used is that of the map (prefer 3857 rather than 4326 -in degrees-).
The offsets (varied according to the parameters chosen) in height of each cut simulate parallel or perspective views, a ‘radial’ vision attempts to get closer to the vision that an observer can have.
A ‘ridge line’ calculation enhances the reliefs.
- have an altitude raster image. different possible sources: https://dwtkns.com/srtm30m/, https://opendem.info, https://grindgis.com/data/free-world-dem-data
- to work in a projection whose unit coincides with the altimetric unit of the DEM (3857, WGS 84 / Pseudo-Mercator for example).
