Web software to create thematic maps for precision agriculture

Abstract: The objective of this work was to develop and provide a free web application able to generate thematic maps. The initiative aims to incorporate the functionalities of the “Software para Definição de Unidades de Manejo” (SDUM) desktop application, which has proven to be suitable for working with thematic maps and management zones, but that was only available for desktop computers. The developed web application was tested with real data from two agricultural fields located in the state of Paraná, Brazil. Thematic maps of soil and plant characteristics relevant to precision agriculture were created through the following interpolation methods: inverse distance, moving average, and nearest neighbor. The obtained results show that the usage of this web tool allows identifying areas with the same behavior toward soil variables, making it possible for the user to have a better and more accurate vision of the area to be worked on and to identify possible causes of variation in productivity. Because it is installed in a server with on-demand features, the software has a satisfactory performance from a functional point of view and can be accessed from any web environment.

摘要：本研究旨在开发并提供一款可生成专题地图的免费网页应用。本项目旨在整合「Software para Definição de Unidades de Manejo（缩写SDUM）」桌面应用的功能，该软件已被证实适用于专题地图与管理分区的相关工作，但此前仅支持桌面端使用。本次开发的网页应用通过巴西巴拉那州两处农田的真实数据开展测试。研究采用反距离法、移动平均法与最近邻法三种插值方法，生成了与精准农业相关的土壤与植株性状专题地图。研究结果表明，使用该网页工具可识别出土壤变量表现一致的区域，帮助使用者更全面、精准地掌握待作业区域的整体状况，并定位产量变异的潜在诱因。由于该软件部署于支持按需服务特性的服务器中，从功能性能维度来看表现优异，且可通过任意网络环境访问使用。
