Conefor for Processing

13.07.2023 14:19 ·  GIS  ·  qgis, plugins, processing

At the beginning of the year, I developed a new plugin — Conefor for Processing.

Conefor (previously known as Conefor Sensinode) is a tool to quantify the importance of habitat areas and links for the maintenance of connectivity. It is also used to evaluate the impacts on connectivity of habitat and landscape changes. Conefor is used to conduct a spatial ecology analysis and conservation planning. The Conefor for Processing plugin contains tools to prepare data and perform all types of analysis available in the Conefor.

The new plugin is a great addition to the Circuitscape provider I have developed before. Together, these plugins create a powerful set of tools for spatial ecology and conservation, allowing researchers from different fields to predict the movements of animals, evaluate the impact of climate change on range shifts, analyse the spread of invasive species or disease, understand how landscape patterns affect gene flow, and much more.

MIL-STD-2525D symbol renderer for QGIS

09.07.2023 09:26 ·  GIS  ·  qgis, plugins

To be effective on the battlefield, make informed and timely decisions, the army needs to analyse tons of data. While all information comes from various sources and in different forms, it ends up being laid out on a map. There are many ways to represent it, and one of them is by using special symbols like the ones described by NATO APP-6D and DOD MIL-STD-2525D standards.


Processing providers updated for QGIS 3

17.01.2018 17:43 ·  GIS  ·  qgis, plugins, processing

As QGIS 3.0 has entered the “hard freeze” phase, it is time to update the plugins. I decided to start with Processing providers, as they are the most relevant. As of today, all of them are updated and available for installation from my plugin repository:

WhiteboxTools for Processing

23.12.2017 09:59 ·  GIS  ·  qgis, plugins, processing

Yesterday I published a new plugin — WhiteboxTools Processing provider.

WhiteboxTools provides a set of spatial analysis tools, primarily for raster data. It was developed as a response to numerous requests coming from users of the specialized GIS called Whitebox GAT. People wanted to use Whitebox GAT functionality in automated data processing workflows. At the time of this post, WhiteboxTools already contains more than 250 tools from Whitebox GAT and about the same number will be added in the near future. The WhiteboxTools for Processing plugin I have developed integrates these tools into QGIS.

The plugin is already available from my plugin repository. Only QGIS 3.0 is supported. Currently, the plugin has an experimental status, so do not forget to enable experimental plugins in the QGIS Plugin Manager settings. In addition to the plugin, you should also download and install WhiteboxTools and specify their location in the Processing settings.

what3words and QGIS

17.03.2016 06:00 ·  GIS  ·  qgis, plugins

Have you ever tried to pass the coordinates of any location by phone or explain to someone where to find a specific place on a map in the absence of a map? This is not an easy task: not everyone can easily memorize long coordinates, and it is difficult to recognize them, especially when spelling over the phone. Of course, there are different techniques designed to simplify this. For example, one can say coordinate in full, spell it by individual numbers, or even use the International Phonetic Alphabet (of course, if interlocutors are familiar with it). But anyway, it is slow, inconvenient, and error-prone.

In such cases, the what3words service comes to the rescue. With its help, one can pass the coordinates of any location with 3 meters of accuracy in just three words. All you need to do is install the Android/iOS application or open the website, find the desired point on a map, and copy three words that encode the point’s coordinates. For instance, V. N. Karazin Kharkiv National University (Svobody square, 4), where the GIS-Forum 2016 is currently taking place, is at robes.mimics.array.

The service is free and already supports 8 languages. The number of supported languages grows every month.

QGIS users can install the plugin of the same name developed by BoundlessGeo. The plugin allows you to get the coordinates of any point in what3words notation and quickly navigate to a location defined by what3words coordinates.

New Photo2shape

21.11.2014 08:30 ·  GIS  ·  qgis, plugins, photo2shape

I have released a new version of the Photo2Shape plugin. This is a QGIS plugin that allows you to create a point vector layer from a set of geotagged photos.

Users now have the ability to recursively process directories and the option to append data to an existing file. The code has also been refactored, and instead of EXIF.py the more convenient and reliable exifread is now used.

GdalTools update

03.02.2010 15:36 ·  GIS  ·  qgis, plugins, gdaltools

Today we merged the experimental branch of the GdalTools plugin into the main development branch.

GdalTools (aka Raster Tools) provides users with a simple graphical interface to perform the most common raster processing tasks. Originally the plugin was created by Faunalia (Paolo Cavallini, Giuseppe Sucameli and Lorenzo Masini), the icons for the extension were created by Robert Szczepanek. About a month ago I also joined the work (and this experimental branch is my work).

This is what we ended up with:

Yesterday my patch adding import/export of connection settings to geodatabases and WMS servers was accepted.

When the user clicks on the import/export button, the following simple window appears

Manage connections dialog
Manage connections dialog

The file to which the data will be written (or from which it will be imported) is selected at the top, and the connections from that file are displayed below. Multiple selection can be made using the Ctrl and Shift keys, also list items can be selected by dragging the mouse.

Once you have saved the file, you can transfer it to another machine and add the necessary connections in a few clicks.

I also forked Tim’s ImagesToShape plugin, rewrote it to use the EXIF.py module and added some improvements. This is how Photo2Shape was born. It is already released, but there is not much feedback yet, or rather none at all :-).

Geotagging tools

27.01.2010 17:22 ·  GIS  ·  qgis, plugins

Recently Tim Sutton published a blog post about geotagging with free software and released his QGIS plugin for it. The plugin uses the exiv2 library and requires the python-exiv2 package, which is not available on Windows/OSGeo4W. Therefore ImagesToShape is not available from the plugins repository.

As I’m interested in geotagging myself, I contacted Tim and offered to rewrite the plugin, abandoning exiv2 in favour of a pure Python module.

Approval granted, so I start work on the plugin.

Improving GdalTools

23.12.2009 16:28 ·  GIS  ·  qgis, plugins, gdaltools

I’ve already submitted some patches for fTools, now it’s time to look at GdalTools. I have already added an “Info” tool to display information about the raster, implemented internationalisation support, added several new options to the “Merge” and “Warp” tools, and now I am working on a batch mode. There are also plans to add more tools.

Hopefully I will be able to get most of the work done before the New Year, and then I will start improving Statist and developing another plugin.
