Abstract
Aspects of the disclosure relate generally to condensing sensor data for transmission and processing. For example, laser scan data including location, elevation, and intensity information may be collected along a roadway. This data may be sectioned into quanta representing some period of time during which the laser sweeps through a portion of its field of view. The data may also be filtered spatially to remove data outside of a threshold quality area. The data within the threshold quality area for a particular quantum may be projected onto a two-dimensional grid of cells. For each cell of the two-dimensional grid, a computer evaluates the cells to determine a set of characteristics for the cell. The sets of characteristics for all of the cells of the two-dimensional grid for the particular quantum are then sent to a central computing system for further processing.
