Need help projecting data....again

RyanMiller — Wed, 01 Aug 2012 16:55:47 GMT

I have downloaded a State-wide wetland dataset from the FWS website, clipped it down to the County of interest and now need help with projecting it correctly to line up with our current data. This seems to happen to me every time so if someone has any good resources on this subject I would appreciate it.

Anyway, I attached the dataset information below of interest (vbc_wetlands2) along with another dataset (County Drains) with the desired projection. Any suggestions?

Thanks in advance!

Wetland Layer to be re-projected:

Data Type: Shapefile Feature Class
Shapefile: P:\temp\MI_shapefile_wetlands\vbc_wetland2.shp
Geometry Type: Polygon

Projected Coordinate System: NAD_1983_Albers
Projection: Albers
False_Easting: 0.00000000
False_Northing: 0.00000000
Central_Meridian: -96.00000000
Standard_Parallel_1: 29.50000000
Standard_Parallel_2: 45.50000000
Latitude_Of_Origin: 23.00000000
Linear Unit: Meter

Geographic Coordinate System: GCS_North_American_1983
Datum: D_North_American_1983
Prime Meridian: Greenwich
Angular Unit: Degree

Current dataset of desired projection:

Data Type: Shapefile Feature Class
Shapefile: J:\VANBUREN_GEODATABASE\Shapefiles\liaa update\County Drains.shp
Geometry Type: Line

Projected Coordinate System: NAD_1983_StatePlane_Michigan_South_FIPS_2113_Feet
Projection: Lambert_Conformal_Conic
False_Easting: 13123333.33333333
False_Northing: 0.00000000
Central_Meridian: -84.36666667
Standard_Parallel_1: 42.10000000
Standard_Parallel_2: 43.66666667
Latitude_Of_Origin: 41.50000000
Linear Unit: Foot_US

Geographic Coordinate System: GCS_North_American_1983

Transform the data using the Project method:

If any exist, read up and use the best Geographic Transformation method.

Hi Ryan,

Here are some KB articles to help.

http://blogs.esri.com/esri/arcgis/2009/05/06/about-geographic-transformations-and-how-to-choose-the-right-one/

Also be sure to know where to find your geographic transformation in your ..\Program Files\ArcGIS\Desktop10\Documentation folder or here - http://mappingcenter.esri.com/index.cfm?fa=arcgisResources.more
