According to the NCC News, the web services of the country's rivers and catchment basins which were produced by the Cartography and National Atlases Department, are presented by the General Department of GIS and SDI.

These web services include the spatial information of the country's catchment basins and rivers network which are as follows:

 1- Catchment Basins Web Service: A catchment basin is an area where rainwater runoff is amassed by waterways and directed to an outlet such as a river, reservoir, lagoon, lake or sea. The catchment area of the country includes six super-basins, each of which is divided into small basins and several smaller categories.

These six super-basins are: 1- Caspian Sea catchment 2- Persian Gulf and Oman Sea catchment 3- Urmia Lake catchment 4- Central Plateau catchment 5- Border catchment.

This service includes spatial information of six super-basins of the country and their sub-basins in 6 levels, which has been prepared by the NCC.







2- Rivers network web service:
The country's river network, by integrating the country's 1: 25000 maps data of the National Cartographic Center, satellite images (ETM, IRS) and information layers extracted from IRAN's Water Resources Atlas (Ministry of Energy) was prepared and ranked by using the Staller method.
This service includes the information of the country's river network, which has been prepared using the Australian method in 8 ranks.






It is noted that the catchment basins and rivers network service of the country is a subset of the products sub-portal of the National Cartographic Center of IRAN / Maps and Charts / Thematic Maps.
