This DSM category complements the more conventional one based on satellite, airborne and terrestrial imagery, which, in the same period, has seen an important evolution in terms of resolution and acquisition technology.<\/p>\n<p>Optical temporal analysis is typically carried out using 8-\/16-days temporal composites derived from medium resolution data, such as MODIS. The combination of Sentinel-2 and Landsat-8 high resolution time-series complements\u00a0 the more conventional MODIS based one by providing a higher level of detail, particularly important in agricultural related applications.<\/p>\n<h4 class=\"chapter\"><span style=\"color: #0018b7;\"><strong>Mod<\/strong><\/span><span style=\"color: #0018b7;\"><strong>ules<\/strong><\/span><\/h4>\n<p style=\"margin-bottom: 0;\">Opticalscape &#8211; available in ENVI and QGIS environment &#8211; is a modular set of functions supporting:<\/p>\n<ul class=\"ul\" style=\"margin-left: 30px;\">\n<li>The generation of DSMs based on satellite, UAV, airborne, and terrestrial stereo images.
