Production Activities
Acquiring Topographic Data in Northern Canada (Carto-Nord Project)
Objective: Complete the topographic coverage of Northern Canada at the 1:50 000 scale by January 2012.
-
Planimetric component
The work consists in capturing 3D topographic features using aerial photography Natural Resources Canada (NRCAN) aerotriangulation survey database. After, update the captured data using SPOT or Landsat7 orthoimages provided by the Center of Topographic Information of Sherbrooke (CTIS), in accordance with the acquisition specifications of the Carto-Nord Project.
-
Altimetric component
The work consists in providing to CTIS a digital elevation model (DEM) that corresponds to the Canadian Digital Elevation Data (CDED) product standards and the effective acquisition specifications using sources provided by the CTIS.
-
Qualification
Contractors that wish to qualify for the CartoNord project must have relevant and meaningful experience in stereo photogrammetric data capture. Knowledge in geomorphology related to the Northern Canada is also useful.
The qualification consists to produce 1 dataset (planimetric and altimetric component) to the CTIS satisfaction. The qualification is neither subject to payment nor reimbursement.
Twelve weeks are allocated from the signature of the contract to complete the qualification contract to the CTIS satisfaction.
Then, completing a transition contract to the CTIS satisfaction will qualify the Contractor for this type of work. The basic amount allocated for the transition contract is determined according to the complexity of the area dealt with.

Note
Strating April 2010, SPOT-HRS imagery will be used for 306 datasets. This 3D source will be used in priority where air photos are not available. This source will also be used for the Altimetric component.

Updated the data of the Geospatial Data Base “BDG” (MAJBDG Project)
Objective: Update data from the Geospatial Data Base (GDB) using SPOT 4&5 or Landsat7 orthoimages.
Qualification requirements
A qualification is a prerequisite for this work and is neither subject to payment nor reimbursement. The qualification process consists to update four datasets in accordance with the effective acquisition specifications and the contracting out standard.
Twelve weeks are allocated from the signature of the contract to complete the qualification contract to the CTIS satisfaction.
The CTIS accepts to qualify firms from April 1st to September 30th.
Note: The CTIS recommends strongly reading and understanding the acquisition specifications using the demo datasets before starting a qualification.

Production of National Hydro Network (NHN) Data
Objective: Complete the first national coverage in NHN data, using Natural Resources Canada's (NRCan) digital topographic data, in compliance with the "National Hydro Network, Canada, Level 1, Edition 1.0" Standard. Then, gradually replace this first NHN national data coverage by current data, of better resolution and more recent data or of higher NHN completeness level data.
Data updates of NHN source data is carried-out via the GDB Update project (see description above) or via partnership agreements with interested provincial and territorial governments. The use of updated source data in the generation of NHN data generally improves their completeness level. The CTI-S is also implementing an NHN regeneration process to produce data compliant with the NHN Completeness Level 3.
Provincial and territorial partners who whish to make their hydrographic data available on the GeoBase Web portal in compliance with the NHN Standard, may do so by producing directly their NHN data in compliance with the NHN model, or since early 2009, they may opt for an intermediate model named NHN-Hybrid. Once the data compliant with the NHN-Hybrid model, CTI-S has the responsibility to generate the final NHN data and publish it on the GeoBase Web Portal.
Documentation describing the official NHN Standard as well as good data coverage are available on the GeoBase Portal under the National Hydro Network section. Then refer to the Description/Documentation and Data/Download sub-sections.
For 2011-2012, NHN data production aims:
- The production of new NHN Work Units where new data becomes available;
- The replacement of some NHN Work Units where the source data has been updated;
- The replacement of some NHN Work Units by NHN data generated from provincial source data;
- The improvement to the NHN Completeness Level 3 (NHN-CL3) for a limited number of NHN Work Units.
The production of new or updated NHN Work Units is carried-out by a CTI-S internal automatic process using the best available NRCan data. The Carto-Nord and GDB Update (MAJBDG) processes are the contracted activities contributing to the NHN data production. For more information on these processes, please refer to the above respective sections.
The production of NHN-CL3 data will start with an internal experimental production of a limited number of NHN Work Units. This production aims among others to determine if such activity can be carried-out via contracts to the private industry. In such case, the required qualification will be established late 2011-2012. Note that the volume of data to produce at the NHN-CL3 has yet to be determined.
