More than 70% of the earth's surface is covered by water. Sea transportation is the main means of moving goods and raw materials needed by the economy of maritime countries. Currently, more than 85% of the commercial exchange of our country is carried out by sea. Hydrography is considered as the key to infrastructure development of coastal countries. Lack of resources to provide accurate, reliable, publicly available, networked and up-to-date marine location information has caused many problems for the country's maritime users, which, in addition to the dangers of navigation, the use of foreign mobile software or applications such as Primar, Navionics, Cmap, etc.,Which have sometimes been sanctioned for Iran, by Iranian sailors will bring special security-technical problems. The production and publication of nautical charts is the most important infrastructure of hydrographic knowledge.
none of which have achieved the desired result, and at best, they were satisfied with the ability to load grid layers in one system. But surly no institution in the country has provided services based on vector layers and with OGC standards. At the global level, there are various systems for providing nautical chart services, these systems have the ability to provide various types of nautical charts with different features.
The launch of this system is vital because by providing an accurate, up-to-date and practical service, all navigational information, including sea charts with appropriate scale, weather information, marine remote sensing identifiers, marine traffic, etc., can be recorded and monitored, and this It shows that it is possible to act more precisely in order to create the aristocracy of spatial information in the maritime domain and to reduce as much as possible the access of other countries to the maritime information of the blue borders and prevent its various consequences.
