LiDAR data interpolation is an important step in LiDAR data processing. Interpolation arithmetic involves high time complexity. Now it is difficult to tackle it by existing centralized processing because of increasing datasets. Emerging Grid technologies is a cost-effective solution for solving scientific problems that involve large datasets and complex analyses. In this paper we present a grid-based architecture to coordinate various resources as LiDAR data processing platform, utilizing centralized task scheduling and parallel computing technologies. LiDAR data is partitioned into appropriate slice and neighboring slice boundary is overlap. These slices are send to each node by scheduler. Computation speed is improved by parallel computing of each node. Grid service is the interface of interpolation arithmetic. In addition, it is beneficial to make these available to the community in a unified framework through a portal, so scientists can focus on their scientific work and not be concerned with the implementation of the underlying infrastructure.
