Rural Municipality of Springfield Information Bulletin 99-7 Page 3 INTRODUCTION The location of the Rural Municipality of Springfield 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 99-7 Rural Municipality of Springfield LAND RESOURCE DATA Base Layer The soil and terrain information presented in this bulletin was Digital base map information includes the municipality and compiled as part of a larger project to provide a uniform level of township boundaries, along with major streams, roads and land resource information for agricultural and regional planning highways. Major rivers and lakes from the base layer were also used purposes throughout Agro-Manitoba. This information was as common boundaries for the soil map layer. Water bodies larger compiled and analysed in two distinct layers as shown in Figure 2. than 25 ha in size were digitized as separate polygons. Soil Layer The most detailed soil information currently available was selected as the data source for the digital soil layer for each rural municipality. Comprehensive detailed soil maps (1:20 000 to 1:50 000 scale) have been published for many rural municipalities. Where they were available, the individual soil map sheets were digitized and compiled as a single georeferenced layer to match the digital RM base. Map polygons have one or more soil series components, as well as slope and stoniness classes. Soil database information was produced for each polygon, to meet national standards (MacDonald and Valentine, 1992). Slope length classes were also added, based on photo-interpretation. 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 different soils ("associates") each of which occurs in a repetitive position in the landscape. Modern soil series that best represent the soil association were identified for each soil polygon. The soil and Figure 2. Soil and Base Map data. modifier codes provide a link to additional databases of soil properties. In this way, both detailed and reconnaissance soil map polygons were related to soil drainage, surface texture, and other soil properties to produce various interpretive maps. Slope length classes were also added, based on photo-interpretation. Rural Municipality of Springfield Information Bulletin 99-7 Page 5 SOIL AND TERRAIN OVERVIEW excess of 255 m asl.
