NextGIS plugins, part 1: tile cache, coordinates, data binding

QGIS is one of the best modern desktop GIS and the NextGIS team has been involved in its development since 2008. In addition to supporting our own build, NextGIS QGIS, we develop extension plugins for QGIS. 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.

Our plugins are designed to simplify, speed up and automate work processes. The plugins are available to everyone and work in both NextGIS QGIS and QGIS 3.

We begin a three-part series describing the plugins developed by NextGIS. The description of each plugin is accompanied by a video tutorial.

Click-Fu: open map click coordinates in QGIS in the map web services

The one-click plugin allows you to switch from the map in QGIS to the most famous web mapping services. Google Maps, OSM, Flickr Maps, GeoHack Map Sources are supported.

It is enough to choose a service and click on the place of interest on the map in QGIS. Your browser will immediately open this service in the click coordinates.

DumpLoadField: add data from TXT-file to the vector layer attributes

Fill text fields of the vector layer attribute table from TXT file. The plugin is used in cases when you need to fill an empty field or when you need to replace values in an already filled field.

With DumpLoadField you can save the contents of an attribute table field to your PC as a TXT file.

Geometry Paster: copy the geometry of one object and assign it to another

With two different vector objects, you can compile the geometry of the first object and assign it to the second.

This creates a “duplicate” of the object, but the style remains the same.

QTiles: create raster tiles from the QGIS project

If you need to quickly prepare an offline basemap pad from your QGIS project, do it with the QTiles plugin. It creates raster tiles for the selected area and in the desired scaling range.

The most common use of such a set of tiles is to work with a mobile GIS in the field without Internet.

Connect Points: connect the points of the two layers by the value of the attributes

This is a simple tool for quickly joining points from two different layers with lines. Attribute values are used for joining.

QuickMapServices: basemaps and geoservices for GIS

One of the most famous plugins among QGIS users all over the world. It is an open catalog of substrates and geoservices with the ability to add them to your GIS.

Copy Coords: copy click coordinates into QGIS

Copy the coordinates of any point to the clipboard. Working with the plugin is extremely simple – no Ctrl+C – just click and the coordinates are copied!

The coordinates are copied in the coordinate system that is set for the project. With SHIFT pressed, the coordinates are automatically converted to latitude-longitude (4326).

EasyQuery: quick search and filtering of vector layer objects

The plugin offers a simple and intuitive visual query builder. You can use it to set a simple condition for filtering layer objects by attribute data and define the sampling mode, without having to delve into the query language.

The values are automatically loaded into the field:

  • all unique values for string fields;
  • minimum, maximum values, as well as the values of 25, 50 and 75 percentage intervals for the numeric fields.

This allows you to make typical queries without entering anything in the value field.

If you set several conditions, you can specify whether at least one of them must be satisfied or all of them at once. The result of the selection can be saved to a separate temporary layer, selected or filtered in the current vector layer.

Identify+: view photos in object attributes

Use the Identify+ plugin in QGIS to view photos contained in object attributes in the program interface.

NextGIS Connect: turn your QGIS project into a hosted interactive map

You can use the plugin only if you have your own NextGIS Web GIS.

The extension allows you to post your QGIS project on the Internet in a matter of minutes. The published project becomes an interactive web map.

With a published web map, you can import individual layers into QGIS, edit them, and update the web map.

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.
