This post is about recent updates to the USGS Spectral Library Data Download. Recently the **USGS** has removed the previous Spectral Library download service and the new download information is at https://www.usgs.gov/media/files/usgs-spectral-library-data-download-information-docx , which describes the download of the whole archive as a .zip file. Consequently, the Semi-Automatic Classification Plugin tool to Download USGS Spectral Library can't work. However, it is still possible to import the USGS libraries using the Import tool. Following the main steps to import a library: 1. download the main archive ASCIIdata_splib07a.zip from https://www.sciencebase.gov/catalog/item/586e8c88e4b0f5ce109fccae 2. create a directory and move one spectral library (name ending with _AREF.txt) and the wavelengths file (file name splib07a_Wavelengths_ASD_0.35-2.5_microns_2151_ch.txt) in it 3. create a .zip file of this directory which can be imported in SCP. For any comment or question, join the Facebook group or GitHub discussions about the Semi-Automatic Classification Plugin.

This post is about******Remotior Sensus**, a Python package that allows for the processing of remote sensing images and GIS data. In this tutorial we'll see how to search and download Sentinel-2 images and calculate the Normalized Difference Vegetation Index (NDVI) using Remotior Sensus. Following the video of this tutorial.

This is a tutorial about******Remotior Sensus**, a Python package that allows for the processing of remote sensing images and GIS data. In particular, this tutorial illustrates how to create a high resolution jpg image from a Sentinel-2 image. Of course, this tutorial could be extended to other satellite images such as Landsat. Following the video of this tutorial. Read more »

The new **version 8.3** of the **Semi-Automatic Classification Plugin** (SCP) has been recently released, which enables the localization of the user interface. I invite you to partecipate to the **translation of the user manual** and the SCP interface **to your language**. Also, I would like to thank the 190 persons who already joined the translation project. **Your contribution is fundamental** for every user who doesn't speak English. It also can be a fun way to learn more about the SCP. Read more »

The **Semi-Automatic Classification Plugin (SCP)** has been updated to**version 8.3.0**. This new version requires **Remotior Sensus** to be updated to at least version **0.4.0.** ** ** ** ** During the update process of SCP from version 7 to version 8, several tools were excluded in order to give priority to the main plugin functions. With this 8.3.0 update, several tools are reintroduced, such as **Clustering tool for unsupervised classification** (K-means method)**, the Spectral distance tool, the Edit raster tool, and the Raster zonal stats**.

This post is to announce that the **new version 8.3**  of the **Semi-Automatic Classification Plugin**  (SCP) for QGIS will be released the **3rd of  August 2024**. This new version will require the new version 0.4 of the Python processing framework Remotior Sensus, and will include several new features such as such as clustering, raster editing and raster zonal stats. For any comment or question, join the Facebook group or GitHub discussions about the Semi-Automatic Classification Plugin.

I'm glad to announce the update of Remotior Sensus to**version 0.4**. This new version add several new features such as **clustering** , **raster editing** and **raster zonal stats**. Following the complete changelog: * Added tool "Band clustering" for unsupervised K-means classification of bandset * Added tool "Raster edit" for direct editing of pixel values based on vector * Added tool "Raster zonal stats" for calculating statistics of a raster intersecting a vector. * Improved the NoData handling for multiprocess calculation * In "Band clip", "Band dilation", "Band erosion", "Band sieve", "Band neighbor", "Band resample" added the option multiple_resolution to keep original resolution of individual rasters, or use the resolution of the first raster for all the bands * In "Cross classification" fixed area based accuracy and added kappa hat metric * In "Band combination" added option no_raster_output to avoid the creation of output raster, producing only the table of combinations * In "Band calc" replaced nanpercentile with optimized calculation function * Improved extraction of ROIs in "Band classification" * Minor bug fixing and removed Requests dependency Read more »

This **tutorial** illustrates a proof of concept about using **Remotior Sensus** in **Jupyter** through an interface similar to the **Semi-Automatic Classification Plugin.** Jupyter notebooks are interactive documents that can be edited in a web browser, which allow for coding in Python and interact with widgets. Several cloud services offer Jupyter notebooks to code, and for example **Google Colab** is a free service by Google that allows for executing a Jupyter notebook in the cloud. In a recent Remotior Sensus update (v. 0.3), a new module allows for displaying an interface similar to the Semi-Automatic Classification Plugin in Jupyter notebooks, allowing for the interactive search and download of remote sensing images, the interactive creation of Band Sets, training input, and ROIs, and the classification of the bands (the interface is still in development and only a few tools are available). For example the following command displays the interface for downloading products. rs.jupyter().download_interface() Read more »

I'm glad to announce the update of Remotior Sensus to**version 0.3**. The main new feature is a new module for displaying an interface similar to the Semi-Automatic Classification Plugin (which is based on Remotior Sensus) in **Jupyter notebooks**. Jupyter notebooks are interactive documents that can be edited in a web browser, which allow for coding in Python and interact with widgets. The Jupyter interface is **still in development** and only a few tools are available. For the moment, the **available tools** are: * search and download of remote sensing images; * creation and management of Band Sets; * the dock for creating a training input and saving ROIs created interactively through polygons or region growing; * the import of vectors in training input; * the plot of spectral signatures; * the classification of the Band Sets; * a file browser for selecting files or directories. For example the following command displays the interface for downloading products. import remotior_sensus rs = remotior_sensus.Session(n_processes=2, available_ram=1000) rs.jupyter().download_interface() Of course this is a **proof of concept** , considering that this interface doesn't have all the functions of the Semi-Automatic Classification Plugin, and there are a few differences in the look and feel because of the characteristics of Jupyter notebooks. A tutorial describing this new feature will be released soon. For any comment or question, join the Facebook group or GitHub discussions about the Semi-Automatic Classification Plugin.
