Hello Y'all!

    My name is Adam Alsamadisi, I am a student at Rhodes College in Memphis, Tennessee, currently doing research with the Memphis Zoo. With GIS, I am currently creating an information system of the Zoo's Light, Gas, Electric, and Sanitation lines. I have taken the data from their CAD origins (.dwg) to shapefiles (polygons and polylines). I am currently projecting them with the following specifications

    Projected Coordinate System: WGS_1984_BLM_Zone_15N_ftUS
    Projection:Transverse_Mercator
    False_Easting:1640416.66666667
    False_Northing:0.00000000
    Central_Meridian: -93.00000000
    Scale_Factor:0.99960000
    Latitude_Of_Origin:0.00000000
    Linear Unit: Foot_US

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


    Unfortunately though, it does not appear if the layer's information has any spatial significance. I am using UTM because it seems to be the only one that has accurate measurements, but as so far as matching up with ground proofed and reliable data, I'm out of luck. I have tried changing the projections, and for some reason none of the data will georectify as layers (i'm using 9.3). Does anybody have some suggestion

Thanks!
