NWT Centre for
Geomatics Mackenzie Valley Air Photo Project (MVAP) Background
The Mackenzie Mapping Program for
Northern Oil & Gas Development is a federal initiative lead by Indian
& Northern Affairs Canada (INAC), with partners from other federal
agencies, Government of the NWT, aboriginal land claim groups, and the oil
and gas industry. The goal of the program is to provide current 1:30,000
scale colour aerial photography for the area of oil and gas development,
supported by accurate updated DGPS ground control, new 1:50,000 or larger
scale topographic maps with 1m contouring and a matching Digital Elevation
Model (DEM), and a colour digital photo-mosaic of the Mackenzie Delta region and
pipeline corridor to the Alberta- NWT border. It is anticipated that this
information will be a primary environmental and mapping information resource
for environmental management in the Mackenzie Delta region for the next 25
years. Program products (ground control survey data, individual photographs
in digital form, delta region and pipeline corridor photo-mosaics, digital
maps, DEM, etc) will be available at minimal or no cost via Internet (or with
a minor reproduction cost for hard drive of digital data). Copies of
individual prints, or entire sets of photos, are available from the
photography contractor (See contacts below). See maps of the "Completed Areas" here.
Data Distribution: Data Products, including orthotiles, contour, digital elevation models (DEM) and metadata are distributed according to UTM Zone. Data can be view and downloaded from the Data\Downloads page. On the Downloads page, data is prefixed by "MVAP_" and groupd by Contour, DEM and Orthotiles.
Contour Data includes:
DEM Data includes:
Orthotile Data includes:
An index of Orthophoto tiles is available under the MVAP_INDEX category.
See
contacts, below for more information. See a technical description of the
photography, scanning and derived map data: PhotoMapOutline.pdf
Frequently asked questions When the ortho-image tiles are created they range in size from 3-150 MBytes. At this time we can only provide
complete sets of digital data. If the online access described in the
"Access to all images" link does not meet your requirements,then we
can copy the data to your external hard drive. If we do this you will
receive: All the ortho-corrected image tiles (30GB), All the non-corrected
images (241GB), all the contour files (7GB) and all the DEM files (2MB). The
images will be in ECW format only. The contours are shape files and the DEM
are DTED format. Total space required 280GB. Air photo index The following is a list of index
maps of the air photos taken. Click here to see a sample jpeg of an index map. Maps updated
June 6, 2005.
There is a shape file available in
the downloads section under Mackenzie
Valley Gas Project files section. MVGP_PhotoIndex.zip (updated Aug 23,
2005) that has all the centroids with links to tthe photos.
Online access to the air photos There are approximately 4500
images. Each image is approximately 800 Megabytes in size. This is about 3.6
Terabytes or 3,600 Gigabytes or 3,600,000 Megabytes of data. A single image
will fill a CD-ROM or take about 44 hours to download with a dial-up connection.
Making these images available to the government and public users is a
challenge.
