Belated #30DayMapChallenge, Day 4: Green 🍏
This place shows the guitar-shaped forest in Argentina that the farmer manually planted in memory of his wife.
You can easily google the story.
We were interested in applying the #forest mask extraction #Mapflow model to this area. Here is the resulting map that we got.
Bless the farmer and his forestry music 💚

One more map for today's #30DayMapChallenge, Day 5: Map about #Ukraine. 🇺🇦
This is the area near Kharkiv (50.0705, 36.4820), switching between different stages of processing of #Sentinel-2 satellite image:
1) NDVI (colored with Ukrainian flag color palette)
2) TrueColor
3) Field mask extracted from the same Sentinel with enhanced resolution
All was done in #QGIS (using #Mapflow-for-QGIS plugin to download Sentinel and apply the field mask extraction). For the resolution enhancement we used #Skycues who provided us with the testing account.
Having said that the crop field segmentation model is still in the experimental mode and requires time series and manual validation for stable results, it can be combined with high resolution (or enhanced one) to achieve better accuracy.

We have released a new version 1.6.5 of #Mapflow for #QGIS Plugin!
No breaking changes, but lots of small issues to make your work more comfortable:
🌏 The most important is that now you can upload area of interest for the processing directly from the plugin interface, or create a new AOI from the visible map extent (see video)
🌍 Previews from Quadkey and TMS basemaps ('Providers' tab) now works properly, and WMS was removed as nobody used it anyway.
🌏 "Use cache" option is removed as it did not work properly. We are reworking this feature on our side, and will return the option as soon as we're done.
🌎 Raster provider imagery search for #Maxar and #Sentinel now clears previous search results (not previews!) when adding new results to the map, in order to not overflow the workspace. If you want to keep the search result in your project, you can duplicate the layer before the new search.
🌍 ...and other minor improvements that can make login, usage and error handling easier.

What a cool infrared cam of Webb Space telescope.
New images of the Pillars of Creation, which is set within the vast Eagle Nebula, 6,500 light-years away.

#Mapflow AI update: enhanced buildings polygonization
One of the issues with buildings simplification is that not all buildings can be polygonized with our heuristic algorithms.
In the latest Mapflow update we have significantly reduced the fraction of unsimplified polygons by adding a generative-adversarial neural network (GAN) that post-processes the individual building masks to refine their shape – see more in our Medium post.
This is included in Simplification option, which now costs 3 credits per square kilometer: it is worth it! For API users, this step is also included in the default Buildings model.

#30DayMapChallenge, Day 14: #Hexagons
The density map of #Ulanbaator yurts (Ger” in Mongolian). (Our office is not in the yurt, so we have walls to hang posters)
The interesting fact about the #dataset is that it was created by ML model detecting yurts in satellite imagery.
If you want to read the story behind the dataset - check Alexander's blog. He wrote in detail about the model development and published the data on Github.
> There is a special tag in #Openstreetmap “Tag: building=ger” and many yurts are already mapped. But I have done much more, and covered whole Ulaanbaatar, not just downtown — it is more, than 4700 sq. km.

Did you know that November 16th is the Icelandic Language Day?
So, today we have prepared a map of Viking expeditions during Early Middle Ages.
As for todays` #30DayMapChallenge - in a totally minimalistic style, only the routes... and Iceland! However, even in this style, with this impressive expedition range you can see Europe coastal line, main rivers and even a touch of America.
Data: Iceland coastal line - OSM, Viking routes - Wikipedia, drawn by hand in QGIS

We are powering #Mapflow imagery integration. The leading service used to apply the Mapflow AI-mapping algorithms is #Maxar #Securewatch. The point is that the imagery streaming model is very cost- and time-effective for a number of applications. Combined with the feature extraction models it drastically speeds up the whole mapping and analytical workflow. Regarding data access, it's almost like Netflix compared to the good old DVDs.
In the past month we started partnering with HEAD Aerospace Group and SkyWatch to maximize the results of available sources for our clients. However, there is still an ongoing process of integration to get things working smoothly.
To tell more - you can connect your imagery service to Mapflow platform to work with your data or expand your opportunities with new and existing clients.

В следующую субботу, 26 ноября, мы проводим наш первый, совместный с географическим факультетов Национального университета, геоинформационный митап в Ташкенте. 🌎
Мы решили сделать мероприятие по следам Дня ГИС (день геоинформационных систем). Но тема получилась ГИС и Космос. Есть еще свободные слоты для докладов! Ждем вас на митапе, если вы в Ташкенте - с небольших встреч начинается новое движение. 😉

Провели наш первый геоинформационный митап в Ташкенте - ГИС и Космос. Одновременно в Астане прошло мероприятие, посвященное прошедшему дню ГИС.
Удалось познакомиться и пообщаться с местными специалистами из коммерческих компаний, Кадастрового агенства, Космического Агенства, преподавателями Геофака Национального Университета. Один из ближайших митапов решили делать в формате образователного семинара для ИТ специлистов и студентов.
И, кстати, присоединяйтесь к новой группе https://www.tg-me.com/gisgeoasia 👈
