RockWorks will assume a Cartesian coordinate system whereby X coordinates increase in value to the east, and Y coordinates increase to the north. Local Coordinates: Use this if your XY (map) coordinates are undefined, or if they are X and Y coordinates in a local grid (e.g.The following coordinate systems are available, though not all are available for all interfaces and processes. ! If you don't know/don't care what system your spatial coordinates represent, choose Local Coordinates. The intent here is to make it possible to output your maps to Google Earth or other geo-referenced software programs. RockWorks includes the ability to define coordinate systems and units in the Borehole Manager, and in the EarthApps and Utilities datasheets. W4 -4th meridian at 110° west, which forms the Saskatchewan–Alberta boundary and bisects Lloydminster.Coordinate Systems in RockWorks Coordinate Systems in RockWorks.W3 -3rd meridian at 106° west, near Moose Jaw and Prince Albert, Saskatchewan.W2 -2nd meridian at 102° west, which forms the northern part of the Manitoba–Saskatchewan boundary.W1 -1st, also known as the Principal or Prime, meridian at 97☂7′28.41″ west, just west of Winnipeg, Manitoba.The Meridians I care about are as follows: A Meridian is a line that runs north-south on a DLS map and it is the starting point on a map to find things that are WEST of it. In my example "W2" means that the homestead is West of the 2nd Meridian. Let's reverse them and look at them one by one beginning with "W2" which is the Meridian. This address gives us five pieces of information which are presented to us beginning with the smallest unit and ending with largest unit. This was the homestead of Pentile "Peter" Popescul. There are a small number of websites that will convert a DLS land package for you into longitude and latitude and I suggest you look for one of those if that is your need. If I had to build the whole DLS map so that you could trust it, it would be a huge task. I tried to make them 'more correct' in the area around Kayville, Saskatchewan but the point of this page was to communicate how to understand the concepts behind the DLS. So, even though I have put more work into these map overlays than I wanted, they are still far from perfect. I now understand the work that I still need to do and I've thrown up my hands for the moment. I came to understand some of the more technical descriptions in the explanations of the surveys. With each adjustment I made, I got closer. The amount of 'drift' is quite dramatic over short distances in some regions. If I used simple math to calculate coordinates they become inaccurate the farther they got from the starting point. The same goes for moving from south to north. It turns out that as you move from east to west adjustments must be made. Once I compared my results to actual DLS locations I had only been successful in representing land locations in some areas but not others. However, the devil, as they say, is in the details. I was able to generate some map overlays that looked pretty good. I began initially out of innocence thinking that I could make a spreadsheet which would take some of the initial coordinates and then calculate points of longitude and latitude which I could then plug into KML files. I've done a bit of work with Google Maps on this page for the maps. You can read about it in detail in the Wikipedia Article: Dominion Land Survey. It is also used for the western portion of Manitoba and small segments of British Columbia. This method of land surveying covers the whole provinces of Saskatchewan and Alberta. These designations are part of the land survey system called the Dominion Land Survey (DLS) which was implemented in about 1871 when the settlement of the Canadian Prairies was set to begin. Did you happen to uncover some of your Saskatchewan ancestor's homesteads or farms and end up with a designation like SW-16-09-24-W2? I'll bet you were excited like I was when I discovered my first one and plugged it into Google Maps only to find out that the mighty Google will not plot it on a map!! How can you find the location of the land on a map? I'll help you by sharing with you what I have learned.
