GPSeismic Dominion Land Survey Option Canadian users have the ability to use the integrated GPSeismic tool which provides access to the Alberta and Saskatchewan Dominion Land Survey (DLS) systems, as well as the British Columbia Petroleum and National Gas grid system (PNG). The DLS/PNG township option for GPSeismic allows the user to determine from within various applications which section/unit a point is contained in or which corner a point is nearest to. Also, maps can be created for any region which depict the sections/units, and where applicable, road allowance and legal divisions. You must obtain the desired data for Alberta, Saskatchewan or BC. For Alberta, the data is free from AltaLis: http://www.altalis.com For Saskatchewan, the data can be purchased from Information Services Corporation in either NAD27 geographics or NAD83 UTM zone 13 grid coordinates. http://www.isc.ca/ For British Columbia, you want the unit level data 'U83' files. There are 151 lettered quad files in UTM83 which are about 4MB each uncompressed: follows: http://srmwww.gov.bc.ca/sstu/portal For Public Land Survey System (PLSS) data in the United States, the DLS option is not required. We have a utility that provides the boundary of a section given the land description or provides the boundary and land description for any point you click on.
