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.
