- Abstract:
-
The SG_TOWNSHIP feature layer, as part of the ISC Sask Grid TFM 2010 data set, contains the annual copy of the GIS layer taken from Information Services Corporation of Saskatchewans live geospatial database at the end of each calendar year. The data is comprised of geospatial locations and attributional information for all of the townships that reside within the province of Saskatchewan. The feature layer identifies each township by township number, range number, meridian number, concatenated TRM identifier and geospatial location. The townships have been derived from legal survey data or theoretical interpolation where survey plans are not available. Their origin can be determined by an FCODE value of Surveyed or Theoretic. This data is suitable for use in Geographic Information Systems (GIS) and Computer Aided Drawing Systems (CAD).
- Purpose:
-
The ISC Sask Grid TFM 2010 dataset is distributed as the annual release of the township, section, quarter-section, legal subdivision and monument layers, which approximate the Dominion Land Survey System grid for the Province of Saskatchewan. The grid is derived from a combination of original township surveys and mathematically interpolated (theoretic) projections, covering the entirety of the province. The data has been designed to serve as the reference grid for a range of applications including oil and gas, land use, planning, emergency response, demographic analysis, land management, and facility management. The data can be maintained via change records on an annual basis.

- Attribute_Accuracy_Report:

* Attributes have been created by two means, depending on the attribute. Some, like the PPID, are generated by the system according to a set of rules. Others, like the legal land descriptors, have been manually entered (transcribed) from the source paper documents. Transcribed values are checked manually on a sampling basis to identify errors. As well external sources of information have been used to validate the values wherever possible. There has been some limited quantification of the accuracy rate for the attribute values, and it appears to be very good. The monument theme attributes qualification has been proven to be better than 98% accurate* General Principles & Rules * The product is spatially integrated with the Cadastral Fabric base. * The aggregate layer is continuously maintained and provides; current status of data; point in time view of data; and date range in support of change records * The theoretic LSD theme is an overlay theme and does not fracture the line work of the quarter sections or other township fabric components, while corners are coincident. * Parent child relationships between township/section/quarter section/LSD are maintained in ISDB. * There are not any LSDs within river-lots or Hudson Bay Company reserves. * Data has been attributed to show the survey status (surveyed or un-surveyed) distinguished by the feature code. * Northern Theoretic Township Geographic coordinates were assembled or calculated for any section corners with sufficient ties to the geodetic framework, along meridians and baselines. Where possible, geodetic control was brought in where northern roads intersected baselines or meridians. Where geographic coordinate values were missing along meridians theoretic township dimensions were applied and theoretic position of points along all meridians were derived. Un-surveyed baselines were projected west from the meridian, holding the latitude at the meridian fixed all the way to the next meridian west. The deflection from baseline to west meridian was applied at the township corner of the last or partial township. From each baseline, the eastern township edges were projected 2 townships north and south. Distances across the resulting correction lines were checked and the coordinate values at the township corners adjusted to make the distance across the correction line approximately one chain in width. All township outlines were then filled-in based on the 3rd system of survey. Road allowances were accounted for. * Northern theoretic townships match existing surveyed base and meridian lines and do not contain separate parcels for road allowances (road allowances are included as part of the quarter sections and LSD's rather than being a separate entity). * Discrepancies between northern theoretic township positions and surveyed baselines are placed in the last section adjoining these baselines. * LSD's in the southern surveyed areas were generated from quarter section monument values, following Dominion Land Survey System rules. * Some Indian reserves, parks and Hudson Bay reserves contain township fabric, but this was not done consistently. * In the southern surveyed portion of Saskatchewan, road allowances are excluded from the quarter sections and LSDs (except southern theoretic LSDs). * Coordinate Disclaimer - Coordinates provided by this dataset are not to be used for placing township or section corners, as these coordinates represent a theoretic reference grid not the positions of township fabric points either surveyed or theoretic. In order to establish township or section corners in theoretic or un-surveyed areas written instructions describing method for establishment must first be received from the Controller of Surveys. As coordinates represent a theoretic reference grid, they may be used to locate existing monuments in surveyed areas.
- Logical_Consistency_Report:
-
All line work data is topologically clean with no gaps or overlaps. The polygonal data does have some gaps between polygons (referred to as "slivers") that were created during the data assembly and loading. The vast majority of these have been eliminated but the remaining slivers require manual intervention to clean them up. These are being removed in conjunction with the maintenance of the data. The number of slivers in the data represent less than 0.1% of the total features.
- Completeness_Report:
-
The data is complete with respect to the entry of information from township plans. All plans that represent currently active primary surveys have been entered. New restoration plans are entered into the Integrated Spatial Database (ISDB) as they are approved, and the ISC Sask Grid TFM Dataset is produced annually.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
The absolute positions in this data set relative to datum are correct to within 5-10 metres in the rural portions of the province and to within 1-2 metres in the urban portions. The relative accuracies are better than 5 metres in the rural areas and 1 metre in the urban areas for points that are near each other. The relative accuracies decrease as the distance between points increases.
- Quantitative_Horizontal_Positional_Accuracy_Assessment:
-
- Horizontal_Positional_Accuracy_Value: varies
- Horizontal_Positional_Accuracy_Explanation:
-
The accuracy of the coordinate varies with the age of the surveys, the quality of the surveys, the quality of the geodetic control and the quality of the ties to the geodetic control. There has been no attempt to quantify these contributing factors. The coordinates were calculated using ties to geodetic control and information shown on plans of survey and then fit together. Where the fit between the various plans was within acceptable limits rubber sheeted (adjusted) to fit. Where plans did not fit together properly other sources of information were used for rubber sheeting, including, but not only, historical survey plans, field measurements, and aerial photographs.
