Assessment of land cover in Al- Najaf Governorate by using the Remote sensation Technics

The geography is the science that study spatial phenomenona and it's changes, classes and the differences. Remot Sensing techniques make a general geographical picture for the earth that shows the differences for the spatial phenomenona through supervising, analyzing and classifying that geographer do by using modern techniques like Remot Sensing.
the uses of land and generally on the landscape of land surface .
In order to know the time classification of the land Cover for the present period, the researcher uses the analytical approach to analyze space images and display them through the visual interpretation and then the automatic analysis and exposition by way of remote sensing programs, especially ERDAS, which is complete program containing supervised and unsupervised classifications
image which consists of four Landsat 7 images well as field images to ensure that the information is precise and the training spots are limited.
The study area is classified according to Anderson Classification. With the assistance of this categorization and remote sensing techniques the researcher reaches at the conclusion that Najaf governorate comprises five land covers as follows:
• Urban Land or Buildings
• Agricultural Land
• Wetland
• Water
• Barren Land
