NextGIS plugins, part 2: vector objects and QML styles

In the second part we will consider plugins for QGIS which automate and facilitate some tasks of vector geometry processing and work with QML styles. The presented plugins will help to:

quickly create linear and polygonal objects from point vertices;
combine lines and cut off their superfluous parts;
extract objects from OpenStreetMap and save them into a vector layer;
apply QML styles to a group of layers;
instantly save QML styles of one or a group of layers to your PC.

As a reminder, our plugins work in our own NextGIS QGIS build as well as in QGIS 3.

Points2One: create lines and polygons from vertices

Create lines and polygons based on the point layer. Group them according to the attributes of the original point layer.

Join lines: permanently join two lines

Permanently join two intersecting or snapped lines. Dangle part will be dropped. Same layer. Not to be mistaken with a multiline.

OSMInfo: get features from OpenStreetMap database at the location

Available objects:

ATDs and boundaries;
Protected areas and water bodies;
all road infrastructure;
buildings, urban infrastructure;
points of interest;
and all other objects from OSM.

When you save the layer, the data structure is preserved as well.

MultiQML: apply a style from a QML file to multiple raster or vector layers

The MultiQML plugin for QGIS is a quick way to assign a single style to a group of vector or raster layers.

In the plugin window you need:

select the data type – raster or vector;
select the layers you want to assign a common style to;
load the QML-file of the style.

Quickly save default QML: save default QML in one click

The Quickly save default QML plugin for QGIS allows to instantly save a layer style to the folder with the source layer.

Group saving of vector and raster layer styles is supported.

Wurman Dots: Mapping Object Density

We’ve developed a new Wurman Dots plugin for QGIS. It helps visualize the density of objects in a point layer. Check out our article for a detailed explanation and a demo video!

Conclusion

The GIS task space is endlessly diverse. Refining and optimizing the software for your business processes should be a continuous process. Become a NextGIS customer and we will be happy to discuss your challenges and needs and to turn them into useful new QGIS plugins.

We have developed more than 30 plugins – more than any other company in the world. These plugins are available in the official QGIS plugin repository.
