Abstract:

The CSRLP system maintains a digital map database as an up-to-date registrar of all registered slope features in the Hong Kong Territories. This dataset contains attributes of slope features which are identified as cut slope, cut slope with retaining wall, fill slope, fill slope with retaining wall, retaining wall, disturbed terrain, natural terrain with stabilization measures and natural terrain with defence measures. Slope Location Plans (SLP) are the graphical presentations of the registered slopes in digital form and record the shapes and locations of the slope features. Basemap information in the SLPs are supplied by the Land Information Centre (LIC) of the Lands Department.

Purpose:

The CSRLP system provides easy search and inspection of the existing slope location by internal staff.

Browse_Graphic:

Browse_Graphic_File_Name:

The 1:5000 series survey sheets' naming convention as adopted by the Survey and Mapping Office (SMO) of the Lands Department with extension. SLP makes up the syntax of the file names.

Browse_Graphic_File_Description:

The file contains all registered slope features being identified by polygons with different colours according to their types. Their associated slope numbers are annotated also.

Browse_Graphic_File_Type: ArcMap 'FGDB' format.

Data_Set_Credit:

The Land Information Centre of Lands Department provides topographic basemaps to the graphic files.

Security_Information:

Security_Classification_System: Windows login control
Security_Classification: Unclassified
Security_Handling_Description: -

Native_Data_Set_Environment:

The CSRLP uses ArcMap 10.8.2 running under Windows 10 for updating slope features, and Oracle 19 for databases.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attribute accuracy is checked by manual comparison of the hard copy plots with the source. In addition, CSRLP customized software tests the spatial data against a master set of valid slope attributes.

Logical_Consistency_Report:

When building topology, all slope boundaries are closed polygons. All slopes' centroid must be enclosed by their associated polygons. Every polygon is associated with an annotation box pointing to it. Annotation texts indicating slope numbers have to be placed inside the boxes. Each polygon is associated with an unique slope number.

Completeness_Report: All registered slopes are included.
Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal positional accuracy for the digital data is checked by visual comparison of hard copy plots with the source.

Process_Step:

Process_Description:

All slope boundaries are stored in Oracle database. New slope and any amendment of existing slope will input into the system's database via ArcMap. Graphic linking between each textual record and its associated graphic elements was established by the in-house customized programme of CSRLP.
