Soils 1:25 000-1:100 000

The soil map shows the distribution of soil species in or near the soil surface and the presence of blocks in the soil surface. The soil types are classified according to their method of formation and grain size composition. Superficial soil layers with a power of less than half a to one meter and soil layers at depth are reported in some cases. Some landforms, such as moraine hill landscapes, moraine ridges and air sand dunes are also reported.
The purpose of the soil map is to provide a basis for analyses of groundwater conditions, the spread of pollutants in soil and groundwater, soil stability, erosion, buildability, natural values and other soil-related issues. The information in the map can be used to produce various thematic products, such as groundwater vulnerability, soil permeability, erosion sensitivity and landslide conditions. The information forms the basis for SGU's printed earth maps and various mapping services.
The mapping has been done with different methods, varying geographical basis and for presentation scales from 1:25 000 to 1:100 000. This means that there are major differences in quality within the product, both in terms of positional accuracy and the division of soil types. The differences in mapping methods used in the mapping are reported by marking the information as different types of maps.

本土壤地图展示了土壤表层及近表层区域的土壤种分布情况，以及地表存在的块状体。土壤类型依据其成土方式与粒度组成进行分类。部分案例中记录了厚度介于半米以下至一米的浅表土层，部分情况还包含深层土层。部分地貌类型亦被纳入记录，例如冰碛丘陵景观、冰碛垄及风成沙丘。
本土壤地图的编制目的是为以下分析提供依据：地下水状况、污染物在土壤与地下水中的扩散规律、土壤稳定性、土壤侵蚀、建筑适宜性、自然价值以及其他与土壤相关的研究议题。地图所载信息可用于制作各类专题产品，如地下水脆弱性、土壤渗透性、侵蚀敏感性及滑坡状况相关专题图件。该信息同时为SGU的印刷版纸质地质地图及各类测绘服务提供了基础数据支撑。
本次制图采用了多种技术方法，制图基准地理范围各不相同，输出比例尺覆盖1:25000至1:100000区间。这导致该产品的质量存在显著差异，具体体现在位置精度与土壤类型划分两个维度。制图方法的差异可通过将信息标记为不同类型的地图来予以说明。
