    Identification Information:

    Source: Survey Department of Ghana
    Feature Type: Raster

    File type: Grid

    Abstract:

    Survey Department of Ghana is the mandated institution for all mapping related activities in the country. This dataset was prepared as part of the department's mandate to provide other relevant state institutions base data for analyses. The DEM has a resolution of 30m and a contour interval of 60m was used to generate the DEM. The main source of this dataset dates back to the 1970s when extensive photogrammetry works were undertaken by experts.

     

    Purpose:

    The purpose of the DEM is to give an indication of the elevation and topography of the terrain of the entire country. The DEM gives a much clearer understanding of the height values for the various high and low lying areas for easier planning and other development related purposes.

    Spatial Reference Information:
    Geographic Coordinate System: 
    GCS_WGS_1984
    Datum:   D_WGS_1984
    Prime Meridian:    Greenwich
    Angular Unit:        Degree

    Projected Coordinate System:  
    WGS_1984_UTM_Zone_30N
    Projection:          Transverse_Mercator
    False_Easting:      500000.00000000
    False_Northing:    0.00000000
    Central_Meridian:  -3.00000000
    Scale_Factor:        0.99960000
    Latitude_Of_Origin:  0.00000000
    Linear Unit:           Meter

    Attribute Information:

    Z - This gives the height value of the surface from sea level

    FCode - This is a code used to differentiate the different categories of the contour divisions
