Reconnaissance soil การสํารวจที่ดินและสิ่งปลูกสร้าง surveys give data for specific soil surveys and wide land use setting up and agricultural progress. (iii) Thorough-Reconnaissance Soil Survey: It can be a mix of reconnaissance and thorough soil surveys which is undertaken for comprehension distribution of standard soil classes of collection as well as their phases. (iv) Semi-Specific Soil Survey: This sort of soil survey comprises incredibly specific examine of some selected strips cutting throughout a lot of aerial-Photograph-interpretation (API) models for acquiring correlation involving API units and soils. This type of soil survey gives adequate specifics of a variety of types of soils, which includes problematic soils.

But as being the map scale decreases (from one: 25,000 to 1: 50,000. or one: one,00,000), sophisticated mapping units are utilised. Approaches Utilized in Soil Survey:
