Abstract There is an increasing need for small scale information about the temporal shifting of the phenological crop development for applications like fertilization, irrigation, crop and soil protection, weather index insurance, yield prediction, crop classification or as bio-indicator of climate change. This application note introduces PhenoWin, a tool to extract and visualize phenological windows for any given year from 1993 onward and user-defined regions in Germany. Phenological windows represent successive start and end dates of development stages for different main crops, which have been interpolated using the phenological model PHASE. PhenoWin was implemented using R language and the R Shiny web framework. PhenoWin can be used as standalone application or can be embedded in web pages. Both, the used phenological data sets and the PhenoWin source code are available under open source license.

PhenoWin - 用于可视化和提取德国物候窗口的 R Shiny 应用程序

摘要 在施肥、灌溉、作物和土壤保护、天气指数保险、产量预测、作物分类或作为气候变化的生物指标等应用中，越来越需要关于物候作物发展的时间转移的小尺度信息。本应用笔记介绍了 PhenoWin，它是一种用于提取和可视化 1993 年以后任何给定年份和德国用户定义区域的物候窗口的工具。物候窗口代表不同主要作物发育阶段的连续开始和结束日期，已使用物候模型 PHASE 进行插值。PhenoWin 是使用 R 语言和 R Shiny Web 框架实现的。PhenoWin 可以作为独立的应用程序使用，也可以嵌入到网页中。两个都，
