We're modeling hyperlocal news articles. Each article is indexed with a shape that corresponds to the region of the map that is covered by the source of the article. We considered modeling the locality of the articles as points, but that approach would have limited our search options to bounding box filters and slow distance calculations. We also felt that the shape approach more closely resembled the true nature of the data. For now, we're only using rectangles, but this approach will give us the ability to index amorphous shapes as well. Are there any other techniques for indexing shape data?
