On the website terraingis. ruyou can find a real storehouse of knowledge for those who work with geodata, especially in the field of cadastral work and the implementation of GIS technologies. This is not just a website, but a living project, which is filled with practical information from a geoinformation specialist - Alexander Fadeev.
The focus is on the topic of local coordinate systems, which are used in various territories of Russia: the Arkhangelsk region, the Republic of Khakassia, the Sakhalin region, the Tomsk region and the Nenets Autonomous Okrug. Each of these systems has its own characteristics, but all of them are created for accurate and reliable recording of real estate, performing cadastral activities and ensuring compliance with the requirements of the Unified State Register of Real Estate.
Local coordinate systems are not just abstract mathematics. These are real tools that allow you to build maps with high accuracy within a certain area. For example, MSK-19 in Khakassia or MSK-65 in Sakhalin - each of them is divided into zones where either design parameters are used or those that are consistent with GOST 51794-2008. And here the most interesting part begins - how to correctly connect this data to the program?
This is where Alexander Fadeev’s blog becomes an indispensable assistant. He doesn’t just talk about formats, he shows exactly how you can add parameters for the transition from a local system to a generally accepted one, for example, from MSK-12 zone 1 to WGS84. True, he sometimes has minor inaccuracies in wording - but this only makes the text livelier, clearer, as if you were reading a practitioner’s diary, and not official documentation.
The material covers in detail questions about working with two main platforms: QGISand GIS Axiom. Each of these solutions has its own approach to implementing local coordinate systems. In QGIS, everything is done through three ways to add parameters - and this is important to know, because skipping one step can ruin the whole job. And in GIS Axiom it is possible to use video instructions that help you better understand the installation process.
Honestly, even if you have been working with these systems for a long time, after reading the article, you will find something new. For example, how to correctly build the format for MSK-70 of the Tomsk region or why MSK-83 of the Nenets Autonomous Okrug needs special attention.
Plus, the site is not just an information portal - it is actively updated. The last publication was published on September 3, 2023, and the most recent was published on May 18, 2025.This suggests that the author lives in the topic, works on current issues, and does not simply drown in old information.
It is simple, but at the same time rich in practical experience. No extra words, no water. Just specifics: what zones, what parameters, how to connect, where to look. Sometimes the text seems a little illegible - commas are missed, phrases are repeated, but this only enhances the feeling of a real person behind the keyboard, sharing knowledge without pathos.
Such things are rarely found on the Internet. Even if you have experience with GIS, it's still worth visiting here. Maybe you didn’t know that MSK-65 is divided into five three-degree zones, or that MSK-19 is one such zone. And now you know.
The site discusses MSK-12, MSK-19, MSK-29, MSK-65, MSK-70 and MSK-83 - each of them is used in a certain region of Russia for cadastral work and real estate accounting.
Parameters of local coordinate systems can be used in QGIS and GIS Axiom - both programs are described in detail with examples of adding parameters for the transition from local systems to WGS84.
This standard defines the accuracy requirements for coordinate conversion. The articles indicate that for some MSKs you can use either calculated values or those that correspond to this GOST - the choice depends on the task.
Yes, there is a video for GIS Axiom that helps you visually understand the process of setting up a local coordinate system - especially useful for beginners or those who want to test their approach.
Such a site not only exists - it lives. He breathes, develops, shares knowledge without unnecessary noise. And if you work with geodata, you should definitely know it.
