To all, I am a very rudimentary user of ArcMap 10.3.1, I use it for several basic operations that typically involve exporting portions of data sets to CAD. However, I have a data set that I believe I need to convert in order to export properly. The rundown:
FEMA makes available GIS data for floodzone information on a County level. This data comes as GCS: GCS_North_American_1983, Datum: D_North_American_1983. We also have the County-produced parcel data which comes as PGS: NAD_1983_StatePlane_Kansas_South_FIPS_1502_Feet
When adding the two data sets to ArcMap 10.3.1, they align appropriately. However, when exporting (such as clipping the FEMA data to a single parcel which is what we will typically do) the FEMA data is scaled at 1/10000 or less and is not aligned with the parcel data at all. It also appears the FEMA data is reduced in a different scale in the Y-axis when the data is manually aligned and scaled.
I would think this is a result of the different coordinate systems though I can not understand why it would appear correctly in Arc but not as soon as you export. Can someone provide a step by step process to address this issue?
I'm certain it's frustrating to well-versed users reading posts like this, but I truly appreciate any help. I find it easier to learn by repeating the actions than trying to stumble through the help index without fully knowing my fundamentals.
