摘要
在实际工作中求算图斑面积一般采用网格法和GIS技术,前者工作量大而且精度不高,后者不易操作和实用性较低,文中研究在实践中总结出的新型简易的图斑面积技术。文章以实例详述Photoshop在基层林业面积测算上的应用以及原理推导,意在推广这一技术在基层林业生产实践中的应用,以提高林业生产效率。
The grid method and the GIS's technology are used generally in reckoning the area- patch in the practical work, but also the accuracy is the former tall greatly amount of work, and the latter does not easily manipulate to let drop with pragmatic quality, and the article is researched the simple and easy technique of new pattern which summarized the practice in.The article.discuss carefullythe application of Photoshop in the basic forestry area measurement by the example and the principle inferential reasoning, intends to promote the application of technology in the basic forestry production practice,.improves the forestry production efficiency.
