Appendix 2 - Project specific Data capture
Many terrain projects are lkely to have project specific attributes. These attributes are not within the standards for digital terrain capture and will not be systematically stored in the provincial data warehouse. However, consulting companies, regions and districts can store and manage this data for their specific applications. At this time the data warehouse will look into storing this data in flat file format only.
With respect to slope classes; the slope tables recorded below provide a format and guide as to how companies can enter their own specific slope classes. However, being that the relationship of slope classes to local and regional topographies can vary, mappers must therefore set their own class limits.
The provincial terrain database committee prefers that mappers record the actual numeric valus of slopes within polygons, this way the information is more definitive and suitable for intrepretations. This is the reason the slope class tables were removed from the database standards and placed in into the project specfic level.
