The dataset is a zip file that contains: i) a file pdf (readme.pdf); ii) a polygon shape file of the study area (study_area_bnd) and iii) 29 polygon shape files corresponding to the layers of the multitemporal inventory (from A0.shp to G13.shp); iv) geopackage of the layers. Each layer represents a different temporal slice, according to the following table. Table 1. List of the layers included in the M-LIM-C. ELA: estimated landslide age. P-I: photo interpretation. F-S: field survey. GSD: ground sample distance. The letters from A to E indicate the layer prepared by the photointerpretation of the stereo-aerial photographs. The letter F indicates the layers prepared through field surveys. The letter G indicates the layers prepared using satellite imagery.
