Posteriormente se restituyó cartográficamente a una escala 1:10.000 desde el layer Imagery Esri 2023, asegurando las características geológicas (componentes salinos) y los sistemas vegetativos y lagunares importantes en el sistema.Finalmente, se revisó y validó la información por un grupo geológico de experto.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 31994, "latestWkid": 31994 }, "copyrightText": "Elaboración: Pedro Fuentes A.
