面向农田信息采集的数字照片空间标识索引方法
Digital photo geocoding and indexing method for field data collection
摘要
Abstract
A kind of automatic digital photo geocoding method based on time threshold, photo indexing and hotlink was developed for precision agriculture field data collection and management. By this method, field multimedia GIS software was developed with functions of digital photo collection, automatic synchronization and geocoding, indexing, hotlink and data conversion as an integrated flow. This software supports different data collection ways such as common digital cameras with hand-held GPS devices, digital cameras with built-in GPS module or smart hand-held PDA with GPS and video camera, which can achieve dynamic photo indexing and linking under GIS environment. Validity and practicality of the method and software were tested by application on field facilities distribution geo-referenced multimedia data collection and process.关键词
