Determines the location of Coal Titles within the Province of British Columbia. It is established under the authority of the Petroleum and Natural Gas Grid Regulation. It is defined by a set of UTM coordinates which approximate NAD 27 latitude and longitude positions. Blocks are the second finest level of the coal grid. A block consists of 100 units divided into 10 rows by 10 columns. There are also 12 blocks in a group, comprising 3 rows by 4 columns and labelled A to L. E.G. 084E05L

European Datum 1950(ED50) is the de facto and de jure geographic coordinate reference system for petroleum industry licencing and operation on the Norwegian continental shelf. The basic input data to this wms service is defined in this Datum, transformations to Euref89 (WGS84) is done on the fly in the server. As the oficially agreed transformations is rather complex, we have choosen a seven parameter vector which gives the smallest overall error |dX| < 1.8m |dY|< 1.7m South of 62 deg N and |dX|< 6.0m |dY|< 2.6m north of 62 deg N.
