The saturated thicknesses are monitored by sensors integrated on wells distributed on a vast geographic area. Our analytics application also captures the trends and patterns (such as average/standard deviation over time, sudden increase/decrease of saturated thicknesses) of water on an individual well and a group of wells based on their geographic locations. To highlight the usefulness and effectiveness of STOAViz, we demonstrate it on the Southern High Plains Aquifer of ","authors_text":"Abdullah Karim, Long Nguyen, Tommy Dang, Venkatesh Uddameri","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GR","submitted_at":"2018-11-18T19:27:56Z","title":"STOAViz: Visualizing Saturated Thickness of Ogallala Aquifer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.07385","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":"sha256:50f1e8cc90b9b316a6f1f4bd5b692a112c8afac45df76d91531007d6fe8c5599","target":"record","created_at":"2026-05-18T00:00:24Z","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":"b6a75c458645cbf2df712a111815ee5756b64515014c0d58a776e59691526fde","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GR","submitted_at":"2018-11-18T19:27:56Z","title_canon_sha256":"5ac6ea1addba0bbc0c6bcb39d0a66064d447c898958833004c2c0a7b021be49a"},"schema_version":"1.0","source":{"id":"1811.07385","kind":"arxiv","version":1}},"canonical_sha256":"959b020681e39fb063e0ea901474f7dded23d578c8be12f0cac13301c7ca2500","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"959b020681e39fb063e0ea901474f7dded23d578c8be12f0cac13301c7ca2500","first_computed_at":"2026-05-18T00:00:24.682601Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:00:24.682601Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ljRFyFKqi0Hig2ggdBjDHiyszOYLv/oSgL5icWqSQpJ5IpMNG8UjLHHjqH/rwWr/CXAyj5b5XnyLE9/tJ+OgBA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:00:24.683090Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.07385","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:50f1e8cc90b9b316a6f1f4bd5b692a112c8afac45df76d91531007d6fe8c5599","sha256:35938a552d4c2a6d8a5fce76f4c28f5b913e45c79de484e59b2edb2c1fc1a5a5"],"state_sha256":"e2dbe2de270579d2bd0753e96fb1c330f91d81a9359a902aa5e5805440cd3524"}
