Progressive drying has been observed in the entire Titicaca-Poop\u00f3-Desaguadero-Salar de Coipasa (TPDS) system during the last decade, causing dramatic changes to Lake Poop\u00f3\u2019s surface and its regional water supplies. Our research aims to improve understanding of Lake Poop\u00f3 water storage capacity. Thus, we propose a new method based on freely available remote sensing data to reproduce Lake Poop\u00f3 bathymetry. Laser ranging altimeter ICESat (Ice, Cloud, and land Elevation Satellite) is used during the lake\u2019s lowest stages to measure vertical heights with high precision over dry land. These heights are used to estimate elevations of water contours obtained with Landsat imagery. Contour points with assigned elevation are filtered and grouped in a points cloud. Mesh gridding and interpolation function are then applied to construct 3D bathymetry. Complementary analysis of Moderate Resolution Imaging Spectroradiometer (MODIS) surfaces from 2000 to 2012 combined with bathymetry gives water levels and storage evolution every 8 days.<\/jats:p>","DOI":"10.3390\/rs6010407","type":"journal-article","created":{"date-parts":[[2013,12,27]],"date-time":"2013-12-27T12:54:46Z","timestamp":1388148886000},"page":"407-420","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Remote Sensing-Derived Bathymetry of Lake Poop\u00f3"],"prefix":"10.3390","volume":"6","author":[{"given":"Adalbert","family":"Arsen","sequence":"first","affiliation":[{"name":"Centre National d'\u00c9tudes Spatiales (CNES), Laboratoire d'\u00c9tudes en G\u00e9ophysique et  Oc\u00e9anographie Spatiales (LEGOS), 14 av Edouard Belin, F-31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Fran\u00e7ois","family":"Cr\u00e9taux","sequence":"additional","affiliation":[{"name":"Centre National d'\u00c9tudes Spatiales (CNES), Laboratoire d'\u00c9tudes en G\u00e9ophysique et  Oc\u00e9anographie Spatiales (LEGOS), 14 av Edouard Belin, F-31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muriel","family":"Berge-Nguyen","sequence":"additional","affiliation":[{"name":"Centre National d'\u00c9tudes Spatiales (CNES), Laboratoire d'\u00c9tudes en G\u00e9ophysique et  Oc\u00e9anographie Spatiales (LEGOS), 14 av Edouard Belin, F-31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo","family":"Del Rio","sequence":"additional","affiliation":[{"name":"Departamento de Geofisica (DGEO), Universidad de Concepci\u00f3n (UDEC), Casilla 160-C,  Concepci\u00f3n 4070386, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,12,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"707","DOI":"10.1080\/01431161.2012.667884","article-title":"Does Lake Titicaca still control the Lake Poop\u00f3 system water levels?
