Abstract:

The dataset was developed as part of the Western Economic Partnership Agreement (WEPA) project covering all of NTS 73M, southern three-quarters of 74D and southeast part of 84A. It contains all the linear landform features such as eskers, flutings and melt-water channels, etc. Part of the dataset was complied by air photo interpretations and followed by random ground-truthing (NTS73M) by AGS geologists. Dataset was then merged with other existing surficial geology maps (NTS 74D and 84A).

Analysis of surficial geological materials, aspects of local relief, and morphological characteristics of surface landforms form an integral component in the evaluation of recharge fluxes to regional groundwater flow systems. To assist in the evaluation of groundwater recharge, terrain analysis maps were constructed in GIS format at a scale of 1:50 000 and 1:250 000 for most of the study area, including all of map NTS 73M (Winefred), the southern three-quarters of map NTS 74D (Waterways), and the southeast part of NTS 84A (Algar). Surficial geology maps of the portion of the study area that lies within map area NTS 83P (Pelican) were published by the surficial geology group in the Minerals Section of the Alberta Geological Survey.

The terrain analysis maps in NTS 73M and NTS 84A were constructed almost entirely from the interpretation of 1:60 000 scale aerial photographs, supplemented with only a minor amount of ground verification. Terrain analysis maps in the area defined by NTS 74D were constructed from both aerial photograph analysis as well as from published surficial geology information (Bayrock, L. and Reimchen, T., 1973). Classification of the terrain was based on interpretations of landform types, tonal reflections of surface materials, differences in vegetative cover, and differences in drainage patterns and characteristics, all of which can be identified on aerial photographs. It is for this reason that the maps are referred to as aerial photograph terrain analysis maps, rather than surficial geology maps, which generally have a greater amount of ground verification. The reader is therefore cautioned that a higher degree of uncertainty exists regarding the information depicted on the terrain analysis map, compared to that on a surficial geology map.

Purpose: To create a Surficial Materials map for the WEPA report

Data Quality Information:
Attribute Accuracy:
Attribute Accuracy Report:
Locations of linear features and attributes (descriptions) are checked visually by comparing the printed map with each Mylar. All discrepancy has been fixed or updated.
Logical Consistency Report:
Linear features of this dataset are extracted from thirty-two 1:50 000 scale surficial materials maps (see Surficial Materials of the Athabasca Oil Sands (In Situ) Area for details). As many of these features are too small/short to be displayed at the final 1:250 000 scale, almost are exaggerated (length wise) and generalized. Their direction and orientation are preserved.
Completeness Report: All linear features identified on the Mylar are included.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
dataset is created by geo-referencing and vectorizing scanned Mylar for each 1:50 000 NTS mapsheet. The average RMS error for the dataset is about 150 meters.

Process Step:
Process Description:
The photo-interpreted surficial deposits were transcribed onto 36 mylar transparencies at 1:50 000 scale and scanned into images. These images were then georeferenced and rectified based on a minimum of four known coordinates. The projection used for georeferencing was Zone 12 Universal Transverse Mercator (UTM) in NAD83. The average registration error is 3 m. The rectified images were converted (vectorized) into lines in ArcInfo. These lines were extracted into separate files (ArcInfo coverages) based on their feature types all unit boundaries were put into one coverage while surface linear features such as esker, glacial fluting, etc. were placed into separate coverages. Each coverage was edited (cleaned and smoothed) in ArcEdit. These processes were performed on all 36 of the 1:50 000 scale maps that cover the study area. Hardcopy map was each coverage was produced and overlaid with its Mylar for quality control. The description of each line feature in the coverage was entered as an attribute in the database. Combining the information in the 36 maps into one created a 1:250 000 scale compilation map of linear landform features in the study area. Detailed surface linear features were simplified (generalized and/or exaggerated) and their general directions and orientations were preserved.
