Urban land use types can be differentiated either by their physical characteristics (such as reflectivity and texture) or social functions. Remote sensing techniques have been recognized as a vital method for urban land use classification because of their ability to capture the physical characteristics of land use. Although significant progress has been achieved in remote sensing methods designed for urban land use classification, most techniques focus on physical characteristics, whereas knowledge of social functions is not adequately u","authors_text":"Carlo Ratti, Chenghu Zhou, Shih-Lung Shaw, Stanislav Sobolevsky, Tao Pei","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cs.CY","submitted_at":"2013-10-23T07:23:02Z","title":"A New Insight into Land Use Classification Based on Aggregated Mobile Phone Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1310.6129","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5f2dee0e406c4339232da518a54148f86e774f0eca043f16505c30ecde667e9b","target":"record","created_at":"2026-05-18T03:09:21Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"72cefbb9ede2ff908c384b60d25805008cda426b22f71f9900298c50854b8cba","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cs.CY","submitted_at":"2013-10-23T07:23:02Z","title_canon_sha256":"0ed7318a765c99e334bda74e8258ce4b46b1946dfce30d8ba96f70d3b88a6faa"},"schema_version":"1.0","source":{"id":"1310.6129","kind":"arxiv","version":1}},"canonical_sha256":"790f58053f4cc5c7186e18e728ecaf628f653f003880810512aa2d23b91a5238","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"790f58053f4cc5c7186e18e728ecaf628f653f003880810512aa2d23b91a5238","first_computed_at":"2026-05-18T03:09:21.373720Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:09:21.373720Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GPKio1mEKRQg12GFQDea0fzT3WhGVg7EoXLBXce64gLBdU1V1howFydoR6EHppTc3m1blG+vPCGMdKyfV7e3AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:09:21.374389Z","signed_message":"canonical_sha256_bytes"},"source_id":"1310.6129","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5f2dee0e406c4339232da518a54148f86e774f0eca043f16505c30ecde667e9b","sha256:4821c8039dd7add7db5e58d156763dc05f23cf4409e8ebe1bd16b6093f91e02d"],"state_sha256":"64e184ff34f7b941f20810cfc98d815d0cf823c795b54db76aadd43d5f7d9fb9"}
