Evaluation of temporal compositing algorithms for annual land cover classification using Landsat time series data

International Journal of Digital Earth, 2023
In this paper, four widely used temporal compositing algorithms, i.e. median, maximum NDVI, medoid, and weighted scoring-based algorithms, were evaluated for annual land cover classification using monthly Landsat time series data.

Nicolas-Auguste Tissot: A link between cartography and quasiconformal theory

, 2016
Nicolas-Auguste Tissot (1824--1897) published a series of papers on cartography in which he introduced a tool which became known later on, among geographers, under the name of the "Tissot indicatrix." This tool was broadly used during the twentieth ...
