This is notebooks illustrates how to obtain and visualize global climate data in R.
This notebook illustrates land cover classification from multispectral imagery using the package ranger which is a fast implementation of random forests.
This notebook illustrates how to assess thematic accuracy of pixel-based land cover classification using different metrics.
This R Notebook illustrates several functionalities to obtain, process and visualize digital elevation models in R.
This notebook illustrates how to conduct land cover classification from multispectral imagery using the terra library. It aims at helping Percepcion Remota students at UNAL to get started with remote sensing image analysis in R.
This is the fourth notebook that GB students need to write to get started with R geospatial capabilities.
This is the third notebook that Geomática Básica students have to write to get started with R & RStudio.
This notebook illustrates how to calculate uni-band and multi-band statistics of remote sensing images using the raster library. I will use a spatial and spectral subset of a Landsat 8 scene collected in 2013. The subset is a seven-band image which covers the area known as Montes de Maria, in the Colombian Caribbean region. I explained in a previous notebook how to find, download, and subset Landsat images.
This notebook illustrates how to improve image visualization of remote sensing images (when traditional contrast stretch techniques are not good enough).
This notebook illustrates how to read, visualize and explore Landsat satellite images using the terra package.
This notebook illustrates kriging interpolation using code written by Barry Boessenkool.
This notebook illustrates how to read, subset and process Sentinel-2 data in R.
This is an R Markdown Notebook which illustrates how to access SoilGrids using the webDAV protocol.
