Rural Municipality of Rosedale Information Bulletin 99-39 Page 3 INTRODUCTION The location of the Rural Municipality of Rosedale is shown in Figure 1. A brief overview of the database information, and general environmental conditions for the municipality are presented. A set of maps derived from the data for typical agricultural land use and planning applications are also included. The soil map and database were compiled and registered using the Geographic Information System (PAMAP GIS) facilities of the Land Resource Unit. These databases were used in the GIS to create the generalized, derived and interpretive maps and statistics in this report. The final maps were compiled and printed using Coreldraw. This bulletin is available in printed or digital format. The digital bulletin is a Windows based executable file which offers additional display options, including the capability to print any portion of the bulletin. Figure 1.

Page 4 Information Bulletin 99-39 Rural Municipality of Rosedale LAND RESOURCE DATA Terrain Layer The soil and terrain information presented in this bulletin was A separate terrain layer was produced for municipalities for which compiled as part of a larger project to provide a uniform level of only reconnaissance scale soil map coverage was available. This land resource information for agricultural and regional planning was compiled by aerial photo-interpretation techniques, using recent purposes throughout Agro-Manitoba. This information was 1:50 000 scale stereo airphoto coverage. The terrain information compiled and analysed in two distinct layers as shown in Figure 2. was transferred from the photographs onto the standard RM base and digitized in the GIS. Where the soil and terrain boundaries coincided, such as along prominent escarpments and eroded stream channels, the new terrain line was used for both layers. The terrain line, delineated from modern airphoto interpretation, was considered more positionally accurate than the same boundary portrayed on the historical reconnaissance soil map. Each digital terrain polygon was assigned the following legend characteristics: Surface form Wetland size Slope Erosional modifiers Slope length Extent of eroded knolls Percent wetlands The four legend characteristics on the left are considered differentiating, that is, a change in any of these classes defines a new polygon. Soil Layer Older, reconnaissance scale soil maps (1:126 720 scale) represented the only available soil data source for many rural municipalities. These maps were compiled on a soil association basis, in which soil landscape patterns were identified with unique surficial geological deposits and textures. Each soil association consists of a range of Figure 2. Soil, Terrain and Base Map data. different soils ("associates") each of which occurs in a repetitive position in the landscape. Modern soil series that best represent the Base Layer soil association were identified for each soil polygon. The soil and modifier codes provide a link to additional databases of soil Digital base map information includes the municipality and properties. In this way, both detailed and reconnaissance soil map township boundaries, along with major streams, roads and polygons were related to soil drainage, surface texture, and other highways. Major rivers and lakes from the base layer were also used soil properties to produce various interpretive maps. as common boundaries for the soil map layer. Water bodies larger than 25 ha in size were digitized as separate polygons.
