Abstract: Utilizing spatial information technology to get wide land parcel information is an important way to improve the field operation efficiency. Using Personal Digital Assistant(PDA) as the hardware platform and based on land parcel data and up-to-date high resolution images data, this paper establishes a land parcel information collection system under GIS environment with PDA as the hardware platform. The system is developed with embedded components. It implements functions including location, navigation and information collection, resolves image compression and cutting problems. Practical results validate the feasibility and high efficiency of the system.

Key words: Personal Digital Assistant(PDA), land parcel information collection, mobile GIS, high resolution remote sensing image

摘要： 利用空间信息技术获取野外地块信息是提高外业工作效率的重要途径。基于矢量耕地地块数据和现势高分辨率遥感影像数据，以个人数字助理为硬件平台，建立移动GIS环境下的地块信息采集系统。该系统采用嵌入式开发组件，实现定位、导航和信息采集等功能，解决高分辨率遥感影像压缩与切割问题。实践结果验证了该系统的可行性和高效性。
