An original point of view
The georeferencing option in QGIS is very handy when we want to have some interesting images on the map canvas. I mean the map images in the vast majority (optionally historical maps), and they will be subject to my explanation in this article. The georeferencing is fairly possible by the Georeferencer plugin (Georeferencer GDAL), which … Read more
Stellarium is a free open-source planetarium, which can be used in different ways. The primary software is dedicated to your computer, but you can still work with Stellarium by using it both via a web application (Stellarium-web.org) as well as an Android application (Stellarium Mobile). Within this second one, there are also another two ways … Read more
This article is probably a compression of the ebook, which I would like to release in the nearest future about the 500 spots, from where you could observe both annular and total solar eclipses worldwide in the 2021-2040 period. I have inspiration from the Sky and Telescope magazine, which has prepared recently a similar list … Read more
This text is somewhat the continuation of the previous one, tailored for the most unique celestial events or group of celestial events, which will occur in the 2021-2030 decade. This time you will read about 10 of the best occurrences in the sky within the next 20 years. Some of the astronomical events described in … Read more
This short post shows you how to install the Python package in Visual Studio Code, which is widely used in the programming environment. The prerequisite for our operation is the Python extension in Visual Studio code, which should be installed at the very beginning (Pic. 1). You can do the installation from this link and … Read more
The Ordnance Survey grid conversion is usually required when dealing with some projects across the UK. Usually, along with the standard WGS 84 datum, we need to define X (Easting) and Y (Northing) coordinates. This task might be quite time-consuming when converting our locations one by one. Fortunately, we have some tools, which can do … Read more
Recently we have entered the new decade 2021-2030. This is a good time to take a look at what major astronomical events will occur throughout this time. I don’t mean typical celestial events, as known from a vast majority of astronomical calendars issued usually on a yearly basis. I would like to take a deep … Read more
It’s still quite a lot of time to the 2026 total solar eclipse event, which has been already considered by me in terms of the possibility of seeing its impact on the atmosphere when the phenomenon happens below the horizon. However, the character of this path of totality requires attention far earlier than normal, as … Read more
If you are interested in long-distance observations or simply panoramic views from some location, mainly mountain peaks or hills, you should have heard about the Ulrich Deuschle panorama generator. This is the web-based tool, which in 2010 successfully superseded its predecessor – Kashmir 3D software, which was based on simple digital elevation model (DEM) files … Read more
There are a few nice tools, which help you to get your map larger than the screen of your desktop. However, all of them are predominantly focused on Google Maps, which is the most popular interactive map platform. If you want to have your Google Map bigger than your screen, even up to 12000x12000Px resolution … Read more
Google Earth is a handy tool, which includes much information. Most of this information can be shown as the layer overlaid on the satellite imagery covering our virtual globe. These layers can be displayed along with our own .kml files plotted into our area. The layers built into Google Earth are not sole. The user … Read more
In this thread, I would like to describe a swift method, which allowed us to make some changes within the .kml files. I am focusing on the names of columns inherited from the .shp files, although the described method can be applied to other texts and even some values too. What is most important, we … Read more
This article is aimed at the recommendation and substantial guideline for apparently the best screenshot application available on the market, which is the PicPick application. Probably you have been wondering how can I create arrows or some weird elements in my screenshots from time to time. All of them have a common source – the … Read more
I would like to introduce the new tool, whose goal is to extract the ephemeris data from the Astropixels.com service. Before I start to describe the major features of my program I would express a big thanks to Fred Espenak the author of this platform. Fred Espenak is already a retired American astrophysicist, whom we … Read more
In the last article about the OpenLayers output from the QGIS2Web plugin, I would like to give up the time for labelling issues, which I believe is another important element of our map, without which it can’t be displayed properly. Sometimes labelling is of the same importance as key, when we want to see where … Read more
When you work with any Excel data, probably you experienced sometimes, that the spreadsheet input looks messy. I personally deal with the address data predominantly, which you could notice by reading my previous articles about geocoding and reverse geocoding. What is the most fun here, even the reverse geocoding results can bring confusion to our … Read more
The total solar eclipse on December 14, 2020, was the last one in the 2nd decade and obviously the first “Twenty Years Solar Eclipse Path Tables” of the XXI century. Most people call this eclipse the COVID eclipse, due to omnipresent travel restrictions, which kept a lot of eclipse chasers in their homes. They could … Read more
Legend and scale besides the pop-up window and labeling is another important map element, which everyone wants to have clean and tidy. In this shorter (I hope) article I want to explain to you how to customize the legend for your OpenLayers map generated by the QGIS2web plugin and add some relevant elements like a … Read more
Another year is coming now. The year will open the 3rd decade of the XXIth century. Time flies. It looks like it’s already 5th time when I am wishing you a Happy New Year! As usual, I would like to share with you the memories from this special night, which is already around the corner … Read more
Continuing the explanation of the ways, where we can upgrade the QGIS2web plugin manually, I would like to explain how to expand the search range in this plugin for more than 1 layer. The plugin supports the option for 1 layer only, but if you need more, coding is required. My goal is to show … Read more
