File Names: Maritimes09a.zip, Maritimes09b.zip (2 Parts)

Author: Gilles Gauthier

Date of Release: May 2003

Version: 1.00

The files in this package contain a new 76m (LOD09) terrain mesh for Canada's Maritime Provinces. The source data is the Shuttle Radar Topography Mission (SRTM-3, 90m). All data were compiled and edited in MicroDEM 6.02, converted with BIGBSQ and resampled to LOD (Level of Detail) 9, or 76.4 meters horizontal resolution, with the Microsoft Terrain Software Developer's Kit (SDK) utilities. The following sections provide information on installation, comments, and procedures used.

1) Extract the zipped files to a temporary directory, making sure that the "use folder names" option is enabled.

2) When the files are unzipped to the temporary directory you should see a folder, called "Maritimes09", with the standard "scenery" subfolder.

3) The "Maritimes09" folder contains this readme file, maps and a couple of screenshots of the new terrain mesh.

4) The terrain mesh .bgl files are in the "scenery" subfolder, and labeled by a geographic name.

5) Move the "Maritimes09" folder wherever you keep your add-on sceneries.

6) Activate the scenery in Flight Simulator 2002 Scenery Library

The river elevation near by Fredericton, NB, have been corrected so some lakes around. (see map NB_correction_rive.jpg). Also, some lake elevations are corrected near by three airports in Newfounland : St.Andrew’s, Stephenville and Deer Lake. (see map NF_correction_lacs.jpg)

The lakes, shorelines and airports are fixed in location and elevation in default terrain mesh. Any new terrain mesh can disrupt this balance.

For CapBreton, Avalon, Gander, Gros_Morne, Halifax, SAndrews, SJohns, Torngat1 and Torngat2 bgl, the SRTM latitude and longitude have been adjusted to fit (as near as possible) the land/water mask (LWM) fixed by FS2002 default files. There will be disrupt in elevations between the bgl.

For Labrador, only the Torngats Mount region have been processed.

The compatibility with add-on sceneries is not fixed.

The 90-m digital elevation model (Shuttle Radar Topography Mission - SRTM-3) for Canada's Maritime Provinces was contained in ftp://edcsgs9.cr.usgs.gov/pub/data/srtm/North_America/3arcsec/ for public distribution.

1) Import QC source data into MicroDEM/TerraBaseII 6.02 (March 2003) and correct data. (Microdem is freeware, by Professor Peter Guth of the Oceanography Department, U.S. Naval Academy: http://www.usna.edu/Users/oceano/pguth/website/microdem.htm)

2) Use BigBSQ.exe freeware utility to convert MicroDEM .dem files to .bsq flat binary format. (John Childs: bigbsq.zip, available at http://www.terrainmap.com/)

3) Use resample.exe (LOD09 - 76.4-m) from FS2002 Terrain Software Developer's Kit (SDK) freeware utilities: http://zone.msn.com/flightsim/FS02DevDeskSDK15.asp

4) Extracting (with BglAnalyze, 3.1) the lake LMW to correct from Hyp536208.bgl, Hyp540212.bgl and Hyp536212.bgl. New ASM file creation with only the LMW to correct. In this file, elevation adjusting to fit the mesh. New specific BGL creation

5) FS Screen for in-flight screenshots.

These sceneries are released as Freeware and shall remain as such.

1) The archive must be distributed without modification to the contents of the archive.

2) The inclusion of any individual file from this archive in another archive without my prior permission is prohibited.

3) No charge may be made for this archive other than that to cover the cost of its distribution. If a fee is charged it must be made clear to the purchaser that the archive is freeware and that the fee is to cover the distributor's costs of providing the archive.

These files are supplied AS-IS. No warranties or guarantees are implied or supplied. I will not supply additional explanations regarding the installation, the use of Flight Simulator or the softwares used with this scenery.
