According to NCC news, On the occasion of December 5, World Soil Day, the National Cartographic Center of IRAN (NCC) celebrated this day with a message which is as follows:

Soil protection, like air and water protection, is essential and inevitable for the care of the planet Earth and its environment, and for survival in general.
Soil protection guarantees a better future for all human beings and future generations. Soil as the basis of agriculture and food supply is the main factor in achieving food security and eradicating hunger in the world. Undoubtedly, healthy soil is the source of healthy and nutritious water and food. Soil hosts a significant share of the Earth's biodiversity, and its sustainability moderates the severity of climate change.

With this description, it is necessary to raise the awareness of human societies about the importance of conservation and sustainable management of soil resources, and to make serious efforts to protect and preserve this vital resource.

Today, modern spatial sciences and technologies play an important role in soil pollution reduction projects, conservation and health programs, and in increasing soil productivity. For example, soil mapping and mapping of distribution patterns and mapping of soil characteristics using aerial and satellite imagery (remote sensing method) are among the necessary measures in the realization of the mentioned plans and programs. Accurate data related to spatial changes in physical, chemical and qualitative properties of soil (in other words, identification and zoning of soil properties), monitoring, evaluation and control of factors affecting land degradation such as soil contaminants, unprincipled land use changes, uncontrolled cultivation and harvesting Excess groundwater resources are also of great importance.

In addition, soil erosion is an expression that refers to the continuous erosion and loss of soil surface, as well as its transfer or movement from one point to another by factors such as water or wind on the surface. Hence, the erosion process involves surface and elevation movements and displacements on the earth's surface, which are often measured by geodetic methods. Today, global positioning systems for satellites are widely used to determine the displacement and deformation of the Earth's surface. In addition, the use of radar satellite imagery and radar interferometry techniques has become an efficient way to measure surface displacements, and with the help of this technology, accurate and continuous monitoring of small surface movements, resulting in phenomena such as erosion and subsidence has become possible on a large scale.

By creating a geodynamic network consisting of permanent stations for positioning and satellite navigation, in addition to determining the coordinate framework of the country, the country surveying organization measures and analyzes the movements and displacements of the earth's crust, especially in active tectonic areas. The organization also processes data from radar interferometric techniques with wide coverage and high spatial resolution, determining the exact position of satellites and the method of accurate alignment, provides changes in the earth's crust in areas affected by subsidence in the form of maps and atlases.

In addition, by designing and developing the National Spatial Data Infrastructure (NSDI), the National Cartographic Center of IRAN (NCC) has shared a variety of spatial information, including cover, case and city topographic maps, digital elevation models, digital aerial and satellite imagery, and a variety of spatial services. Provides users. Obviously, this infrastructure is a good platform that can facilitate and accelerate the access of users, planners and decision makers in the field of soil resources with the participation of active devices in the field of soil resources and with the addition of related general and specialized data sets.
