Abstract: The i-Series Digital Maps, including iB1000, iB5000, iB10000 and iB20000 Digital Topographic Map, iC1000 Digital Land Boundary Map and iG1000 Geo-reference Database, provide more comprehensive datasets in new data formats and enable users to select the seamless version covering users’ defined area-of-interest so that they do not need to combine discrete tiles of digital maps into one single file for their work. The Digital map detail is represented as single coordinated points, or lines of multiple coordinated points. Coordinates of the Digital Map are in Hong Kong 1980 Grid, and heights are in metres above the Hong Kong Principal Datum. Updating of Digital Topographic Map iB5000 Data Structure The data structure of the iB5000 will be changed on June 11th 2024, in which the "ENGLISHNAME" and "CHINESENAME" attributes will be removed from feature classes, BuildingPoly, BuildingsPointAnno_C, BuildingsPointAnno_E, BuildingLine, BuildingPolyAnno_C, and BuildingPolyAnno_E. Users can still access these attributes from the "BuildingsPoint" feature class. You may refer to the proposed iB5000 Data Dictionary version 1.3 (https://pubsharetest.blob.core.windows.net/data/Proposed%20iB5000%20Data%20Dictionary%20-%20FGDB%20v1.3.pdf) for details.

摘要: 「i-系列」數碼地圖包括iB1000, iB5000, iB10000及iB20000數碼地形圖、iC1000數碼土地界線圖和iG1000地理參考數據庫，提供更全面的數據集和全新數據格式。用戶亦可選用覆蓋他們自選範圍的無縫「i-系列」數碼地圖，從此不必再把多個獨立的數碼地圖融合成單一檔案才使用。所有地圖資料以無縫無框的延續方法儲存。數碼地圖採用香港 1980 方格網座標系統，參照香港水平基準量度高度，以米為單位。更新數碼地形圖iB5000的數據結構數碼地形圖iB5000的數據結構將於2024年6月11日更新，包括刪除英文及中文名稱屬性資料，涉及圖層包括：BuildingPoly，BuildingsPointAnno_C，BuildingsPointAnno_E，BuildingLine， BuildingPolyAnno_C，BuildingPolyAnno_E。更新後用戶仍可在圖層BuildingsPoint 內查閱該屬性資料。詳情可參閱建議的iB5000數據字典1.3版(https://pubsharetest.blob.core.windows.net/data/Proposed%20iB5000%20Data%20Dictionary%20-%20FGDB%20v1.3.pdf)。
