On what coordinate system are the SNB Digital Products?
Most of SNB’s digital or paper maps are in reference to NAD83 (CSRS) and the NB Double Stereographic projection is used for plane coordinates: • All cadastral data (PLANET) • All enhanced topographic database files (ETB) • All digital terrain models (DTM) • All digital colored orthophotos Only the NB Atlas book is still in referenced to ATS77. The difference between ATS77 and NAD83 (CSRS) is on the average 4.3 metres, thus well within the scaling precision of coordinates from the Atlas. In this case, one can easily consider the coordinates equivalent to NAD83 (CSRS) for all intensive purposes.
