Operating System:Windows 7 Easy fix?:No

From http://www.mass.gov/mgis/dd-over.htm
The EPSG (European Petroleum Survey Group) code for this coordinate system is 26986.
The Massachusetts State Plane Coordinate System, Mainland Zone meters is defined as follows:
Projection: Lambert Conformal Conic
Spheroid: GRS 80
Central Meridian: -71.5
Reference Latitude: 41
Standard Parallel 1: 41.71666666667
Standard Parallel 2: 42.68333333333
False Easting: 200000
False Northing: 750000

From TOWNS_POLY.prj downloaded from MassGIS

From QGIS Reference System Selector EPSG:26986
+proj=lcc +lat_1=42.68333333333333 +lat_2=41.71666666666667 +lat_0=41 +lon_0=-71.5 +x_0=200000 +y_0=750000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

  • Note that lat_1 and lat_2 are reversed in QGIS


1) load a vector layer in MA State Plane coordinates into QGIS v1.71 (please check v1.73 for the same error) (EPSG:26986) see attached file
2) change the projection for the layer to EPSG: 26986
3) save the layer (possibly with a new name)
4) open the saved layer in QGIS
5) the EPSG for the saved layer is reported by QGIS as EPSG:2805

Not confirmed, I'm using qgis-master and I tried the following:

  • added the attached vector
  • changed its CRS to EPSG 26986
  • saved a copy of the vector with EPSG 26986

after adding the result in QGIS it shows coorectly as EPSG 26986.

I attach the vector. Please test qgis-master (with the osgeo4w installer) and leave feedback.

Thanks for looking at this issue. I didn't have my email notifications set properly in my tracker account, so I didn't get notified of your comment. I will try to download and install the master from OSGeo when I have time and see if I can repeat the error.
