1. A computer-implemented method of generating data objects for multi-resolution geometry in a three-dimensional model, comprising: identifying a region of high resolution geometry in the three-dimensional model, the region of high resolution geometry having a level of detail that is higher than a level of detail associated with geometry data surrounding the region of high resolution geometry in the three-dimensional model; extending a boundary of the region of high resolution geometry to an extended boundary; generating high resolution geometry within the extended boundary; spatially partitioning the high resolution geometry into a plurality of geospatial data objects; and selectively storing one or more of the plurality of geospatial data objects in a memory.
