Monument Sketch
A sketch is a graphical representation of a control survey point in relation
to nearby features such as power poles, centre of highway, etc. It's primary
purpose is to assist in finding the control point in the field. The sketch
provides distance and azimuth measurements to nearby features and some control
point attribute information such as monumenttype and date of last inspection.
Updated sporadically. Format: Available individually by control point number
as individual paper copy. Alternatively, a digital file version of available
sketches (PDF format) is available in the Sketch CD product.

Monument Values/ Control Point Information Report (NSCCS
network points)
A one or two page report is generated for each control point in a request.
Generally the information provided for each control point are ATS77 coordinates;
historic coordinates(usually NAD27), CGVD28 elevation, ATS77 MTM point scale
factor, construction date, last inspection date, type of monument, coordinate
status; if available, connectivity information to other control points.
Updated regularly, printed report.

Monument Index Map (Historical Information)
This is a hardcopy series of maps that show NSCRS network and/or NSHPN control
points that fall within the bounds of a specific map. The map sheets are
based on the NTS 1:50 000 NAD27 series or, a larger scale Inset Map for
areas with a high density of monuments. This series is no longer maintained,
however they do show most of the control points. Each control point is labeled
with a unique number and is the link to the NSCRS database. Maps are available
as duplicate paper prints. Alternatively, a scanned image of each map in
PDF format is available in the Sketch CD product.

SketchCD
This is a 2-CD set that contains available sketches for control points
of the NSCCS network and the NSHPN in a digital PDF file format. One or
more PDF files per control point - 24300 files. Also includes a scanned
image in PDF format for each of the "historical" MonumentIndex Maps. A
data use license is required. (current edition 2003v02) SketchCD (2-CD
set / sketches and MonumentIndex maps).

NSHPNcd
This is a single CD that contains NSHPN control point information. This
includes a network plot file in jpg format, the digital sketch files in
PDF format, digital photographs in jpg format, three (3) fixed width ASCII
text files with NAD83 (CSRS) coordinates, adjustment version NSHPNv1.0,
containing 3D cartesian, ellipsoidal and UTM coordinates respectively.
A data use licence is required. NSHPNcd (current edition 2002v01)

Nova Scotia Coordinate Values / NSCCS.txt
This is a comma delimited ASCII text file containing a comprehensive record
of information for each distributable NSCCS network control point - province
wide coverage. A data use license is required.

Grid Shift File - NS778301.gsb
This file was developed for use with the National Transformation version
NTv2) software or an implementation of it. The file listed is for transforming
coordinates between the ATS77 and NAD83 (CSRS) reference frames. It is a
binary file containing records with the predicted latitude and longitude
shifts between the two reference frames for a grid of regularily spaced
points that covers the Province. Each record also contains a corresponding
accuracy estimate for the shift values. The file is used for the transformation
of points falling within the land mass of Nova Scotia. A data use license
is required. |

Coodinate Transformation Services (Online
and Custom Processing)
Horizontal coordinates (latitude/longitude or northing/easting) and, in
some cases three dimensional coordinates either cartisean (X,Y,Z) or ellipsoidal
(latitude, longitude, ellipsoid height) for discrete points can be submitted
for transformation between NAD27, ATS77 and NAD83(CSRS) reference frames
and/or conversion between the geographic, UTM and MTM coordinate types.
Height transformations between CGVD28 orthometric heights and NAD83 (CSRS)
ellipsoidal heights via the HTv2.0 model is provided as well. Service is
provided through a free, but limited, online coordinate transformation service
and via inquiries by phone, email or fax. A custom processing fee may apply
for some inquiries.

Coordinate Transformation - Online Service This
online web application provides users the ability to submit coordinates
(source coordinates) referenced in one of the supported reference frames
and coordinate types and perform the transformation to one of the supported
target reference frames and coordinate types. Data may be submitted via
keyboard data entry or read from a data file. Check the site to identify
the data file formats supported. |
| Coordinate Transformation - Custom Processing (fee may apply) For
phone, fax, and email inquiries - users should verify input format requirements
for submissions with a large number (>10) of positions. Transformation results
are provided on paper or digital file as required. |
