NextGIS Web - Uploading raster tiles to Web GIS
why we need to transform the DEM?
Hello. In this particular case by two reasons: 1. Transforming DEM to metric coordinate reference system is crucial for calculating derivatives like slope angle 2. All input datasets should have the same extent, pixel size and coordinate reference system as input Land Use/Land Cover rasters, so we should transform everything to their spatial domain
Why does molusce give me "nan" value in the evaluation correlation, do you know anything about that?
Hard to say without data samples. You can send us some to support@nextgis.com and we'll try to figure out
Thank you so much...I was struggle with the matching of the geometry but after watching your videos I solved it.....really appreciate it...
great, brah
Hello, thanks for the video. I am new to MOLUSCE and I am strugling a bit to understand the bottom table in the Area Changes results. For instance, what does it mean the almot 59% in the Barren to Barren transition? Thanks a lot!
Hello! It means that 59% of Barren pixels remained the same class (Barren). And 41% of them were transited to "Natural Herbaceous".
@@nextgis_channel Thanks very much for your answer 🙂
hello,I found the current validation kappa in my result was low (about 30), what should I do? Which part of my model has a problem?😭
Hi, usually it means that your hypothesis about influecing environmental factors is wrong, or model parameters are wrong, or both. First step is to play a lot with model parameters, if metrics dont grow, then you should reconsider spatial variables
Does this not support other map projections?
Hello, I'm in Nigeria. I've been unable to make payment for the geodata I ordered using my debit cards. Please can you tell me what to do.
Hello! Write to the chat, please: t.me/nextgis_talks
Sir.... Which version of qgis you used for molusce support
hi, is there any alternative if I dont have any applied style in my folder? how can I still colored it?
Is it free
There is a free plan, as well as paid ones: nextgis.com/pricing-base/
Thank you for sharing. I'd like to ask, after I used the molusce plugin in QGIS for simulation, the overall accuracy is below 0.6, and the historical accuracy is 0.8. What could be the reason for this?
@user-md3tg8pe5h 0 seconds ago when i add slope map as a spatial variable to predict LULC by Weight of evidence i face a problem that the Rand min and Range max for the slope raster appers as (nan) how can i fix this problem, please?
If "range min" and "range max" values are invalid, it seems to be a problem with your input rasters and their metadata, so plugin is unable to take correct min/max values from it
what about Weight of evidence method, could you teach us about it, please?
It's very simple and doesn't have many things to be tuned. You should only set up the process of converting continuous data to discrete, selecting number of intervals for each factor.
Thank you so much guysss for update it. Really thanks from my heart....... ❤❤❤❤
Hi there, I noticed that your predicted results for 2022 and 2027 are pretty similar at first glance despite the rigorous process. Almost unable to discern any changes from the full view between the 2 iterations. What do you think is the reason?
Hello! Actually hundreds of pixels were changed, so model was able to catch something. But in general hypothesis in this demo case was very weak, so I wouldn't count on results as something real. If we would take a look at transition potential maps for each pair of classes, we would notice that there many potential changes, but model wa not confident enough most of them, so it prefered to leave state unchanged.
What year should the predictor maps (road network, water bodies,etc.) be? And what is the resolution of your input data?
Hello! In current implementation of MOLUSCE predictor maps are static for the whole period, including forecast. It is one of current limitations. Usually it's better to use predictors data relevant for the latest known LULC date. Resolution of data could be different, depending on your study scale. In this video we used MODIS MCD12Q1 data with ~500 meters/pixel spatial resolution.
Thank you sir for providing us Molusce 4 that works in QGIS 3.x, I'm glad to hear that. I'll try.
Finallyy!!
Very good! Brazil
What is the main difference between this version and the previous version?
@@akwijayanto Hi! First of all, the plugin was transited from the QGIS 2 engine to the QGIS 3 engine. It is a huge thing, a lot of internal mechanisms are changed. It also means that we are able to support Molusce again, which was nearly impossible before the update (too much outdated code was inside). Besides that: - Improved styles support. Now Molusce works with paletted/unique values render type, which is the actual standard for land cover rasters. In the previous version you had to use singleband pseudocolor, and in many cases (gaps in class numbers etc.) it wasn't convenient. - calculation efficiency of ANN method has been improved significantly, and stop button now works well (which is very important for fast experiments with training the model under different parameters) - some bugs and UI fixes
Can it be installed in QGIS 3.2 version?
@@tahmidanam6391 hello, minimal QGIS version is 3.22
Было бы неплохо сказать, что для этого нужен платный модуль, иначе WMS просто не будет работать
Can't see what is done on that video. Quality is not very good
Hmm, set the quality to 1080, make the video full screen
Thank you so much for making this plugin. It works with QGIS 3.32.3 and it solved my problem.
Glad it worked for you!
How to do it? Do we need api-key of our dataset?
Hello! To upload via the Connect module, you'll only need your data and/or a configured project in QGIS. Please ask any API-related questions in this chat: t.me/nextgis_talks
how did you get the satellite data?
Satellite data, specifically cloud-free Sentinel 2 mosaics, can be obtained through the NextGIS Data service: data.nextgis.com/
Does this method just create a layer from a google spreadsheet? When adding new records to Google Spreadsheet, these new records are not synchronized with WebGIS?
Indeed, this tool generates a layer using the data from the table. It is important to note that each row should contain coordinates. In case you make any modifications to the table, in order for the new objects to appear on the map, you will need to utilize the tool again and choose the appropriate mode: "ADD" or "REPLACE".
Any idea what the file size would be doing this for the entire US? It would be really nice to have topographic maps of the country and be able to overlay your gps position over it.
it will depend on zoom scales needed
In QGIS 2XX it used to have this function, but also by clicking and selecting 2 layers and clipping the difference between them on the go, without the need to create a new layer/file, where's this function?
Wow!! Want views? Check promo sm!!
Только не совсем понятно, от куда взялась ссылка на svg-маркер.
годится любая прямая публичная ссылка на любой опубликованный файл SVG
Is there a way to clip an OSM to the boundary of a .shp file? Trying to clip the boundary of a country with the OSM in the background. Thanks!

Очень интересная функция. Хотелось бы увидеть, как выглядит результат такого заказа.
Нет проблем, вот тут есть примеры data.nextgis.com/ru/about/#pdf
Спасибо! Очень полезный и удобный модуль 🤗
why don't you port the plugin for qgis 3.X?
Hi! Now it's available for QGIS 3
Can we have this plugin in version 3.X please
Did you got any other plugin like this??
try points to path tool
Thanks@@haidersaady2280
its there in 3.16.16. as [ Connect Points]
@@komal164 , thanks i have seen
i typed in the wrong country name on accident and now i cant edit the search bar.. do you know how to fix this? Thanks!
this plugin does not exist in v 3.6
How does one do this with QGIS 3.10, there is no open layers plugin, and i can't find OSM under Vector
