Hi,
I was considering an import of Connecticut statewide hiking trails
import from DEEP:
http://www.ct.gov/deep/cwp/view.asp?a=2698&q=322898&deepNav_GID=1707%20#OutdoorRecreation
This data is released under Public domain licence:
http://www.cteco.uconn.edu/metadata/dep/document/TRAIL_FGDC_Plus.htm
"Access constraints: None. The data is in the public domain and may
be redistributed. Use constraints: No restrictions or legal
prerequisites for using the data. ...... Once the data is
distributed to the user, modifications made to the data by the user
should be noted in the metadata. The State of Connecticut, Department
of Energy and Environmental Protection and all other Originators
(referenced in the Citation section of this metadata), should be
acknowledged as the data source in products derived from the trail
data. For example, include the following data source description on a
map: Trails - From the Connecticut Statewide Trails layer, compiled
and published by CT DEEP and other trail data collecting agencies and
organizations. Source map scale varies."
Is this compatible with current OSM licence or do I still need
approval from DEEP for use in OSM?
I am not qualified to answer this question, but I'm going to give an
opinion anyway: that sounds to me like a somewhat poorly phrased version
of the standard "you can do whatever you want, but it would be nice if
you gave us credit". The standard way of doing that (as mentioned in
the import guidelines) is to give them a listing at the Contributors
page on the wiki.
As I was looking at the file, I noticed this in the metadata:
Trail line feature information was prepared by collecting trail
positions in the field using GPS equipment, digitizing trail maps,
compiling information onto a planimetric correct base and digitizing,
or by copying previously digitized road and trail centerline
features. Horizontal accuracy varies depending on the methodology
used to map and digitize each trail system. Consequently, as a whole,
these data are generally not intended for maps printed at scales
greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet).
Refer to the Horizontal Accuracy Notes attribute in the Trail line
feature and Roadway line feature class for more specific horizontal
accuracy assessments when mapping individual trail systems at larger
(more accurate) scales. Trail Access point and Trail Interest point
feature information was prepared using similar methods, with
horizontal accuracy varying accordingly.
Sounds to me like care will be needed in importing. Hopefully the source
is listed on a per-feature basis, so any with less accurate sources can
be more thoroughly verified.
