Threshold Vectorization QGIS 4 compatibility
Not QGIS 4 ready Likely abandoned
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Processing plugin-based provider that adds a model to polygonize a raster from a lower and an upper threshold. Provedor do Processing que inclui um modelo para vetorização de um raster a partir de um limiar inferior e um superior.
About
The model added is named TV Vectorization Threshold. For this model to work, the plugin adds this and other models to a group called ThresholdVect, and scripts to a group with the same name. There are a number of parameters that can be set to optimize the polygonization. These parameters are described in the help of the model. Also, a model is added to calculate the NDWI, a possible input to the plugin model that can be used to extract water bodies. To extract water bodies using NDWI, perform the following 2 steps: 1- Extract NDWI using the TV Raster NDWI or TV Multiband NDWI model, depending on whether the bands are in different rasters or in a single raster. 2- Execute the TV Vectorization Threshold model. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- O modelo adicionado é denominado TV Vectorization Threshold. Para que esse modelo funcione, o plugin adiciona este e outros modelos a um grupo chamado ThresholdVect, e scripts a um grupo com o mesmo nome. Há vários parâmetros que podem ser configurados para otimizar a vetorização. Esses parâmetros são descritos na ajuda do modelo. Além disso, um modelo é adicionado para calcular o NDWI, uma possível entrada para o modelo do plugin que pode ser usada para extrair massas d'água. Para extrair corpos de água usando o NDWI, execute os 2 passos seguintes: 1- Extraia o NDWI usando o modelo TV Raster NDWI ou TV Multiband NDWI, dependendo se as bandas estão em diferentes rasters ou em um único raster. 2- Execute o modelo TV Vectorization Threshold.
