How To Obtain These Files:
- 1) Ontario Base Maps are licensed to McMaster University Library
by the Ontario Geospatial Data Exchange Agreement or by the Ontario
Ministry of Natural Resources. They are available only to affiliates
of McMaster University, and may be used only for non-commercial purposes.
-
- 2) The OMNR license form must be signed before the files
will be delivered. A copy of this license form can be obtained in
the Map Collection.
-
- 3) The tiles should be requested by OBM map sheet number. Consult
the paper indexes to the Ontario Base Maps to determine this number
or you can click
here for an online index. Click on this map to zoom in - eventually
it will give you a number for a single OBM sheet. Submit a list of
desired map numbers to the Map Collection.
4) Specify whether you want ArcView shapefiles, ArcInfo Export
format (.e00) or pdf format.
