Sections Modified by Direct Shares in the Cauce

The mapping included in this service contains the sections modified by direct actions in the channel for each of the sections of the inter-Community water bodies. These elements have been obtained and generated as indicated in the Protocol of Hydromorphological Characterisation of Water Masses of the Category Rivers (PHMF), through the comparison between the orthophoto PNOA Maxima Actualidad and the orthophoto of the flight known as American Flight – Series B, made between January 1956 and November 1957.本服务所包含的制图数据，涵盖了各跨社区水体（inter-Community water bodies）各河道段中，因河道直接作业而发生改造的河段。本次涉及的相关要素严格遵循《河流类水体水形态表征规程》（Protocol of Hydromorphological Characterisation of Water Masses of the Category Rivers，PHMF）的规范，通过比对PNOA Maxima Actualidad正射影像与1956年1月至1957年11月期间实施的“美国飞行-系列B”航摄任务所获取的正射影像，完成获取与编制。
