The plugins are available for download and use directly in QGIS, these add useful features to the software. It should be noted that the add-ons are developed by QGIS and by other independent users who want to extend the core functionality of the software.
Below we present a top 5 plugins for QGIS and its functionalities.
5. QuickMapServices
Allows the user to load base layers from fonts such as Google, Bing, Yahoo, Open Street Map and waze, among others. Perhaps this is the plugin one of the most used by QGIS users.
For example, if we want to add a Google base layer or some other, we can add them in the following way:
Or we can add a large number of layers.
4.- mmqgis
MMQGIS is an add-on used to edit vector layers. Input layers can be from any source of geospatial data supported by QGIS. The output file format is contained by the file extension given in the output file name.
With this tool you can make different types of edits to vectorial layers with which you are working in QGIS such as: create animations, joints, geocoding, conversion of geometry, modification of columns, among others.
3. Digitizing tools
This tool is a compilation of tools that are missing in basic QGIS, especially when digitizing into existing features.
The tools covered here range from ring fill, attribute switching, multipart to single part switching, moving, cropping, adding polygons.
2. Semi-Automatic Classification Plugin
This plugin is useful for semi-automatic classification or supervised or unsupervised classification of remote sensor images (satellites), with this plugin you can also download available satellite images. In addition to providing tools for downloading images free of charge from Landsat, Sentinel-2, Sentinel-3, ASTER and MODIS satellites, support in preprocessing these images, postprocessing classifications and calculating raster bands.
1. Georeferencer GDAL
This add-on allows raster to be georeferenced to geographic or projected coordinate systems by creating a new GeoTiff or adding a reference file to the existing image.
This tool is very useful, as you can georeference maps that can be on paper and have in digital format.
