Abstract

To search and localize objects of interest among massive and multi-modality geospatial data is key in spatial computing. However, the effective and efficient searching among an extensive collection of geospatial data (e.g., global satellite imagery, building footprint) for interesting patterns can be challenging. In this context, not only does one need to know where to look to find objects of interest but also which model to use for different searching tasks. What if prior efforts had already created models on an exact or very similar task? How should users search for such models? When models are available, how should they be stored? Many applications become possible if we manage to make large data collections and models searchable by content, metadata, and analytic tasks. Application users would like to solve these challenges by knowing which model to use, which task the model is relevant for, and how to simultaneously search across all geospatial data representations (vector, raster, text, fields, point clouds, etc.), and finding all objects of a certain type in a huge data cube (e.g., a large point cloud or time-series EO data). In the long term, users will want to search broadly, interactively, quickly, and using different or even mixed modalities.

SuP-SLiP: Subsampled Processing of Large-scale Static LIDAR Point Clouds

Annotation is a crucial component of point cloud analysis. However, due to the sheer number of points in large-scale static point clouds, it is an expensive and time-consuming process. We address this issue using a novel lightweight approach to reduce ...
