How do I convert Ecologys GIS data to NAD 27 (or any other projection)?
In ArcGIS, use ArcToolbox: Click on: • Data Management Tools • Projections and Transformations • Feature • Project Choose the dataset, the name you want to call the output, and then the output coordinate system. At this point you can also choose the projection of your choice, for example, UTM. For Washington stateplane: Choose: • Projected Coordinate Systems • State Plane • Nad 1927 • NAD 1927 StatePlane Washington South FIPS 4602.prj Of course, if your project is in the northern counties of the state, you will want to choose NAD 1927 StatePlane Washington North FIPS 4601.prj. For the Geographic Transformation, you need to add two transformations: • NAD_1983_To_HARN_WA_OR • NAD_1927_To_NAD_1983_NADCON Click on the Button to choose them from the menu. Workstation Arc/Info: If you have a coverage and are using workstation ArcInfo, use the PROJECT command with the COVER option: ARC: project cover
