QGIS resultant shape correct by way too big! #26

Closed dougbrugg closed 7 months ago

dougbrugg commented 4 years ago

Thanks in advance for reading and any advice! I set my layer projections to NAD83 [4269] to draw surveyor results across a parcel in the US. Define the starting point using decimal degrees. Under Options I selected "Bearing" and under Distance unit "Default" was selected. I loaded the csv file with azimuth and distance using ; as separator. Distance units are ft. Clicking draw produces the right shape but at a huge magnitude. The projection of the resulting shape is NAD 83 [4269]. Any ideas would be great!!

This plugin uses Euclidean geometry, so it only works with planar projections, not ellipsoidal coordinate systems such as NAD83 or WGS84. See https://github.com/mpetroff/qgsazimuth/issues/12#issuecomment-291692157.

While it doesn't work with NAD83 directly, it works fine with the NAD83 state plane zones.
