I don't use QGIS for Archaeology per se, but for forest management plans. Since forest soil is usually undisturbed for centuries, the forests are full of historic and archaeologic sites ("Bodendenkm?ler"). It is vital in forest management that these sites stay undisturbed. So in preparation of a management plan I use officially/openly available data of the Bodendenkm?ler and I also check the DGM if there are any abnormalities or distinctive features visible. I mark everything on a map that I'll load into QField and check the sites when I'm on location. > I would be very grateful for any insights on the following questions: > > Do you use QGIS only as a GIS client, or have you also used it for documentation/database-like workflows in archaeology or cultural heritage? I use it in documentation/database-like workflow for forest management. If I have the data available, I will load past management plans to track the changes to the new management plan. I mostly use Spatialite and occasionally PostGIS. Both have the benefit of being able to use a variety of tools to extract data from and write data into the database. For the management plans I have a couple of R-scripts with a collection of functions in combination with SQL-script templates. In the past I've also used LibreOffice Base to manage the data and bring it into reports. > Are there known limitations when using QGIS for long-term excavation documentation, metadata management or multi-user environments? I strongly recommend to do any documentation, metadata and multi-user management in a database. There are no specific limitations when using QGIS, the limitations are more on the database side. > Do you have recommendations for combining QGIS with external databases (e.g., PostgreSQL/PostGIS, SQLite/Geopackage)? Geopackage works great a data exchange format and as a singe-user database. Although for the latter, I prefer Spatialite, as it has more functions in the database. For multi-user, (incremental) backups, version control there is no way around PostGIS. Generally, I strongly recommend to use a Free Software/Open Source solution. For your specific use case you will easily pay the same if not more for a proprietary CAD/GIS solution, but then no-one else can benefit from your specific developments and licensing internally in your org is a hassle. One forest administration that I know is set on ESRI products since decades, but the licensing and distribution restrictions now lead to a lot of workers using QGIS for their tasks. So now they have two GIS infrastructures, one official and expensive, on informal with no proper documentation or backup strategy. It's the same as the uncontrolled distribution of macro-ladden Excel-sheets in large organizations. If you don't have the expertise in-house, you should hire a consultation agency to help you set up a database schema and an initial workflow. QGIS specific and already in the market with a lot of solutions for the public sector, norbit GmbH comes to my mind. They are also contributors to QGIS: https://www.norbit.de/ Best regards -- Tobias A Schula Forestry Expert geospatial at schula.org -------------- next part -------------- A non-text attachment was scrubbed...

The idea is to: There is a difference between "commercial" and "proprietary". Any OpenSource software can be "commercial" in nature, as it is allowed to sell it, sell service around it, or documentation? The commercial aspect is not impacted by opensource licences. The business models are different though, as any end-user or other person obtaining the software is allowed to copy and redistribute it, leading to a situation where "licence-based" or "royalties-based" business models are not really possible. Proprietary software is any software not respecting the 4 foundamental principles of OpenSource, usually by using a non-opensource ( non-OSI-approved ) licence. > Use QGIS as the main GIS platform / interface, > Integrate or call a YOLO-based object detection workflow (e.g., as a plugin, script, or external service), > Package this as a solution that I sell to my customers (either as a service or as software they install). > > I would be grateful if you could clarify the following points: > > Licensing and redistribution > > QGIS is licensed under the GPL. Under what conditions may I bundle QGIS with my own code and distribute it as part of a commercial offering? QGIS code is licenced under GPLv2 or later. Therefore, you can only bundle code that is compatible with GPL version 2 or version 3. As soon as other code is linked with QGIS ( e.g. a python plugin *importing* qgis modules, or c++ code dynamically linked by a compiler), then this code needs to be GPL-compatible. Also note that GPL version 2 and 3 are not compatible. If you bundle QGIS and other codes *not linked*, but working together by other means, then the GPL "virality" does not apply. > If I write a QGIS plugin that uses YOLO (for example, a Python plugin calling external inference code or a remote API), does this plugin also need to be GPL-licensed, or can it be under a different license? Your plugin and any library/module it imports needs to be GPL compatible, therefore GPL or a more permissive licence ( e.g. MIT ). > Are there specific requirements for how I should provide source code, notices, or license information when distributing QGIS together with my own software? As far as licence compliance is required there is no specific requirement, you must provide access to source code, and licence informations for any user, but _how_ you do it is up to you. If you want to distribute your plugin, there may be additional requirement though, according to the platform you use. > Commercial use and charging customers > > Am I allowed to charge customers for installation, customization, training, and ongoing support of a QGIS-based solution that includes my own YOLO-based object detection tools? Yes, as said above, there is no commercial aspect in opensource software. There are trademark rights for QGIS you have to comply with though : https://qgis.org/community/organisation/guidelines/ All of this said, you should think twice about your business model and the way you will develop your activity and product. It is generally speaking not advised to fork projects. Maintenance costs will be your sole concern if you do not contribute anything back upstream. Also, packaging is a hard task and should not be taken lightly. Also, keep in mind that you will necessarily be part of an ecosystem and a community, be it technical or economic. You should stay fair with it, and not act as a freeloader towards the QGIS community at large, the YOLO developers, or any other contributor who shares time and money for the public goods.

Hi Jeroen, which QGIS version are you using exactly? Which WKT type is the input point layer? AFAIK the "Points to Path" (native:pointstopath) processing algorithm correctly adds the M value to the output line vertices if the input points have an M value as you can see in the screen recording available at https://jumpshare.com/s/5J2ipdRIijEiNJUkTTmO.

You need an attorney versed in open source licensing, and a business consultant who understands the landscape. Your description is all over the place and it sounds like you don't understand. You've already gotten some good advice, including a comment that I'll second that it is rude to ask the Free Software community for zero-cost help with your business. > QGIS is licensed under the GPL.

Generally, plugins are considered a derived work under copyright law because they use the QGIS APIs. Thus, it is improper to distribute them under a license other than GPL2. > Am I allowed to charge customers for installation, customization, training, > and ongoing support of a QGIS-based solution that includes my own > YOLO-based object detection tools? There are no prohibitions against charging for your time to help people in the GPL. But don't take my word for it. Read it yourself, very carefully, and go over it with your attorney. That is usually considered the honorable approach to making money in a Free Software context.

Perhaps you could store everything inside a geopackage rather, similar to a CAD file, although yes, they are not all linked. You could then do table join if you wanted to, but probably unnecessary. You can emulate the CAD colours by having a CSV table of RGB colours, which relate to the CAD colour names and which then you can link to the attributes and use the RGB in your colour expression and in the same way as well as line type. You can also emulate the line thickness by using the attribute in the line layer. Hopefully this helps. --- Regards, Nigel Berjak Please consider the environment before printing this email.

Did you import the dxf via import-tool (onboard or ?another dxf importer?-plugin) or drag and drop?

Here I will just summarize some points to observe. If your software is derived from a GPL code, as stated by the license itself, your software has to be GPL licensed as well and it has a series of obligations (described in license) about full source code distribution. If our software is developed using LGPL libraries, again as stated in in the license itself, ou may keep your code closed, but there is a series of obligations described in the license itself. This is how a large number of commercial closed source software (e.g. Oracle Database) can exist and be sold targeting platforms like Linux based systems If your is derived, or based, of proprietary/comercial software with non GPL/LGPL licenses ou have to study those licenses and act according to them. Bundle QGis with your software may not be a problem, provided that you fulfill your obligations as stated by the license. Other possibility is ou sell/license your software only and let the the clients know what version it will support. If you are investing in commercialization of your software, as suggested in other answer to our questions, the better way to be safe is consult a lawyer specialized in IP and Licensing.

But since a QGIS plugin will be distributed linked with QGIS anyway, best is to directly licence the code under a GPL licence. Also, beware of GPL2 / GPL3 non-compatibility. To all QGIS users, if you want to simplify things and stay safe, publish your plugins under a "GPL v2 or later" licence.

My name is Lars Uhlmann and I am studying Geothermics at the Technical University of Munich and at the Friedrich-Alexander University of Erlangen-N?rnberg. At the moment I am doing my Master Thesis with the topic "Creation of a subsurface model for Erlangen and derivation of geothermal potential". That is why I am writing this email, as I need help with how to display the underground model in QGIS. I believe that it is possible to represent the thermal conductivity of the subsurface in subsurface polygons down to a depth of 50 metres. The Problem is that I dont know how to do that by myself. Just a quick addition to give you a better idea of the data basis. I have around 400 boreholes in the urban area of Erlangen (80 km?) with depths ranging from 1 to 200 metres. These are very well documented stratigraphically (in some cases in 1 m increments). I would like to connect these layers and then, for example, form a 2D surface of the subsoil every 5 metres in order to map the thermal conductivities there. The data is available as an Excel file. Please feel free to write to me if you need further information. It would be very helpful for me if someone could tell me whether this is possible in QGIS and either provide instructions, a YouTube video or perhaps offer their own help! You can reach me by this email lars.uhlmann at fau.de or at this number_ +49 1766 444 1849 in English or German. Many thanks for every reply and kind regards, Lars Uhlmann :)
