Geo2020 地質剖面產製 (Geo2020 Geological Profile Builder) QGIS 4 compatibility

讀取經濟部地質調查及礦業管理中心 Geo2020「工程地質探勘資料庫」MDB 檔（內建純 Python Access 讀取器，免安裝 ODBC），在地圖上顯示鑽孔位置，並依剖面線、數值地形 (DEM 或等高線) 批次產生地質剖面 QGIS 專案檔 (.qgz)，所有圖層存入 GroProfile.gpkg。剖面包含鑽孔柱狀圖（依 2008 資料作業規範附錄B 工程地質圖元符號，內含全部 131 個圖元）、地形線、土岩界線、地下水位、RQD、SPT、不連續面，以及含圖例、比例尺、格線的版面配置。另提供岩心箱照片檢視工具：點選地層即顯示對應深度的岩心照片；以及 3D 剖面預覽與 3D 剖面成果圖：DEM 地形貼上平面圖，剖面圖（含技師修改後的剖面專案）立於剖面線位置。 about=⚠ 警語：本工具為地質剖面「製圖輔助」工具，不能取代地質專業判斷。地質模型須由熟知地質原理、能建立地質概念模型的地質師負責建構與確認；不具地質專業者請勿僅依本工具成果進行工程判斷，建模時應諮詢應用地質師。 【用途】節省鑽孔柱狀圖繪製、圖例配置、SPT／RQD 展示等製圖工作，讓地質師把時間留給地質模型的思考與判斷。功能分三部分：(1) 讀取地礦中心 Geo2020 工程地質資料庫（MDB），依 2008 資料作業規範附錄B（131 個圖元）自動繪製鑽孔柱狀圖；(2) 依鄰孔分層、地質事件先後順序（斷層、不連續面、地層面）及代表位態，產生地層界線連接與視傾角延伸的「初稿」；(3) 將地質師編修確認後的剖面組成 3D 地質剖面與地層界面展示。 【限制】 - 成果品質取決於 MDB：鑽探資料須正確輸入、分層須合理。鑽孔柱狀圖的分層不必然等於剖面應採用的地層分層，可能需要細分或整併。 - 自動產生的界線、視傾角延伸及由 MDB 建立的地層界面，均為未經確認的初稿。須由地質師依地質概念模型檢核、修正剖面（必要時修正 MDB）後才能使用。 - 3D 地層界面為內插、外推結果，遠離鑽孔與剖面處屬推估。不整合、褶皺、複雜斷層等地質構造無法自動判釋。 - 成果的地質合理性由使用者負責。 Reads Taiwan Geo2020 engineering-geology borehole databases (Access MDB, built-in pure-Python reader, no ODBC needed), shows borehole locations, and batch-generates one geological cross-section project per section line using a DEM or contour layer. Layers (strata columns with the official Geo2020 lithology patterns, terrain, soil/rock interface, groundwater, RQD, SPT, discontinuities) are stored in a single GeoPackage and each project includes a print layout. A core-box photo viewer shows the core photos of a clicked stratum, and a 3D preview / 3D result page shows the (edited) sections standing on the DEM terrain draped with the plan map. ⚠ Disclaimer: this plugin is a drafting aid for geological sections and does not replace geological judgement. Geological models must be built and checked by a qualified geologist able to develop a conceptual geological model; users without geological training should not rely on its output for engineering decisions and should consult an engineering geologist. Purpose: it saves the drafting work (borehole logs, legends, SPT/RQD display) so geologists can spend their time on the geological model. It (1) draws borehole logs from the Geo2020 engineering-geology database (MDB) with the 131 standard symbols of the 2008 data specification; (2) drafts stratum connections and apparent-dip extensions from neighbouring holes, the order of geological events and representative attitudes; (3) shows the sections, once edited and confirmed by the geologist, as a 3D model with stratum interfaces. Limitations: results are only as good as the MDB data and its layering, and borehole layering is not necessarily the stratigraphy to use in a section. Automatic boundaries, apparent-dip extensions and MDB-based interfaces are unconfirmed drafts that must be checked and corrected by the geologist. 3D interfaces are interpolated and extrapolated, so areas far from boreholes and sections are estimates. Unconformities, folds and complex faulting are not interpreted automatically. The user is responsible for the geological validity of the results.
