Converted CAD shapefiles seeminlgy lacking all spatial reference

[adamalsamadisi125]

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 suggestions?

Thanks!

Hey Adam - So is your problem that the data's projection information doesn't persist in the dataset or that it's not lining up with other, more accurate data?
