      Scale_Factor_at_Central_Meridian: 1.0

      Planar coordinates are encoded using distance and bearing
      Planar coordinates are specified using distance and bearing values. Resolution of distance values: 1
      Resolution of bearing values: 0.0002778
      Bearing is specified in units of Degrees and decimal minutes
      Bearing is measured North
      Bearing is measured from the Magnetic meridian
      Planar coordinates are specified in Meters

      The horizontal datum used is Hong Kong 1980 Geodetic Datum.
      The ellipsoid used is International Hayford (1910).
      The semi-major axis of the ellipsoid used is 6378388.
      The flattening of the ellipsoid used is 1/297.0.

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   Everyday the core database (M10000) of the Small Scale Mapping System (SSMS) are updated in accordance with the daily changes in Computerized Land Information System (CLIS) data, viz. 1:1000 scale basic map (B1000) and the Geo-reference data. This approach ensures the data currency of the SSMS with respect to the CLIS data source.
   Validation tools are developed for the purpose of validating the SSMS data with reference to those of the CLIS and other relevant sources. On the other hand, software utility would also be deployed to check the accuracy of the SSMS annotations in map products in different scales.
   The B10000, which is derived from the M10000, comprises the graphic and attributes that should pass through a validation process with respect to M10000 before the dissemination to other Offices, Government Departments and public.

2. How accurate are the geographic locations?

   Over 90% B10000 data are derived from CLIS data [B1000 basic map data and Geo-reference dataset from CLIS]. Daily updating has been deployed in M10000 of SSMS to ensure the data currency of the SSMS with respect to the CLIS data source. There is a dependency on the B1000 database because point features in B10000 are extracted from B1000 whilst linear features are generalized with not more than 10 percent of the points tested shall be in error by more than 0.8mm, measured on the publication (1:10000) scale. Polygons are generated in 1:10000 accuracy but retained the characteristic of the footprint. Road widths are exaggerated, with reference to the centre line of B1000 basic map, to the nearest 10m, 15m and 20m for clarity of presentation.(Note: These limits of Horizontal Accuracy shall apply in all cases to positions of well-defined points only.)

3. How accurate are the heights or depths?

   Vertical Accuracy, as applied to elevation features on 1:10000 publication scale, shall be such that not more than 10 percent of the elevations tested shall be in error more than one-half the contour interval.

4. Where are the gaps in the data? What is missing?

   The entire territory of Hong Kong is represented by a total of 59 tiles in 1:10000 scale covers. They have been completed and are regularly updated in 6-month revision cycle.

5. How consistent are the relationships among the observations, including topology?

   Whereas shades are maintained in DGN, DWG and DXF formats, polygon and chain node topology are presented in ArcInfo format.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
