We are doing the research about applying remote sensed data on hydro logical model . After delineating, the river basin from DEM data using Argis9.3, We have to map the remote sensed data derived from products like PERSIANN. Our task now is to create the grid with the same resolution with the available remote sensed data( for example 0.25degree x 0.25 degree). and have a certain corner that matches with the obtained data. Does anyone know how to deal with our problem? Your help is highly appreciated.
The tool which does this is Create Fishnet - it can be used to create polygons, polylines and labels at regular intervals i.e. a grid of squares or rectangles in any coordinate system.
