Nº 033-2008-AG, divididos y codificados con el método Pfafstetter. Escala 1:1'800,000\nLa informacion fue proporcionada por el MINISTERIO DE AGRICULTURA segun OFICIO N° 221-2009-ANA-SG/DGCCI\nEl Mapa contiene unidades de tipo cuenca -en gran mayoría- incluyendo las intercuencas de mayor tamaño en el Amazonas y la Intercuenca Ramis en el Titicaca.\nPacífico : 62 Cuencas\nAmazonas : 39 Cuencas y 45 Intercuencas\nTiticaca : 12 Cuencas y una intercuenca\nEstas unidades fueron seleccionadas, en primer lugar, por su importancia en estudios de evaluación e inventario de los recursos naturales (deviene de las cuencas determinadas por la Oficina Nacional de Evaluación de Recursos Naturales - 1980); en segundo lugar, por la ubicación que ellas representan respecto a la unidad mayor a la que pertenecen, por el cual estas unidades podrán ser identificadas por su código y nombre. El número de dígitos corresponderá al nivel de jerarquía que se encuentre la unidad.\nTOPOLOGIA: Poligonos.\nNo DE ELEMENTOS: 231 poligonos.\nFUENTE DE LA INFORMACION GRAFICA: Unidades hidrograficas\ngeneradas a escala 1:100 000, utilizando la Cartografia Digital Base del\nInstituto Geografico Nacional (IGN).\nESCALA DE LA CAPTURA DE LA INFORMACION GRAFICA: 1:18000 V 1:8 000.\nTIPO DE ENTRADA DE LA INFORMACION GRAFICA: Digitalizacion\nvectorial por pantalla.\nEMPRESA/ORGANISMO EJECUTOR: IRH-INRENA / MINAG (Lima)\nFECHA CREACION DE LA COBERTURA: 2 008\nDOCUMENTO DE OFICIALIZACION: R.M.
