Where do I find the coordinate system for a data frame?
Go to View > Data Frame Properties > Coordinate System tab, and verify that a Current Coordinate System is set for the Data Frame. Note: The coordinate system of the Data Frame is adopted from the first data added to the new Data Frame.
What to do when spatial reference does not match data frame?
The spatial reference of the layer does not match the projection of the data frame. Solution: Ensure that the projection information of the layer matches the other layers and the data frame. This may mean that you need to reproject a layer to match the data frame or change the projection of the data frame to match the layer.
What happens when data is based on a different coordinate system?
If the data are based on a different geographic coordinate system, such as the North American Datum of 1927 (NAD27), ED 50, Amersfoort, or Tokyo; then misalignment may be quite noticeable at the local scale.
What happens when data is added to ArcMap?
When adding data to ArcMap, the application reads the coordinate system (projection) information stored with the dataset. When displaying multiple datasets with different coordinate systems, ArcMap will project the data ‘on-the-fly’ to the coordinate system that is set for the Data Frame:
Why does Google Maps not match geolocation coordinates?
Cad has indeed forced that ‘clicked spot’ to correspond to the lat/long of your pin, but it won’t necessarily force your clicked spot to correspond to UTM meters shown in the Google image (it forced the x-meters and y-meters to your clicked spot, not the true easting/northing). Instinct tells us it should match, but it doesn’t.
What to do when data does not line up in ArcMap?
Right-click the name of the layer in the Table of Contents, select Properties > Source tab, and examine the contents of the Data Source box for the coordinate system definition. If there is no coordinate system defined, review the metadata in ArcCatalog, or additional documentation that may have been delivered with the data.
Is the survey database the same as the drawing coordinate system?
Point coordinates are showed up as a fraction of an origin value. Drawing coordinate system and survey database coordinate system are different. Confirm the drawing settings coordinate system is correct. In the Survey tab of the Toolspace, right-click on the the survey database name and click Open for edit. Expand the Import Events and delete all.
