As the nature of this project
involves forestry, I was directed through the Ministry of Forestry to an
office in Fort St. John. I requested coverages of an area of about
6000 km2, from Fort St. John north to approximately Prespatou.
I requested this area because it includes the City and the probable timber
supply area. I received data at 1:250k, but it was not of the quality
and accuracy that I had hoped for.
After requesting better data
and giving a non-disclosure statement, I received some excellent data at
1:20k. Due to the larger scale of this data, I chose to use 25 sheets
covering a smaller area of about 3300 km2. The data was
in ArcInfo format, with 22 coverages and an Excel file of metadata. Coverages
that I found useful were double line water features, roads and trails,
and provincial forest/government reserve. Unfortunately, the forest
cover polygons were actually numbered stands and therefore not of much
use to me.
I obtained further data from conventional maps and personal communication. I digitized the BC Rail line and Fort St. John airport after consulting several maps at scales ranging from 1:50k to 1:500k. I obtained the locational information about the proposed location of the OSB plant from the North Peace Clean Air Association (NPCAA) and digitized this as well.
Unfortunately, I was unable
to obtain data to meet all of the requirements of the Slocan-LP Corp.
Data on hydro power lines was difficult to obtain; therefore, I left this
criterion out of my final analysis. As the location of the OSB plant
is not directly related to proximity of timber sources at such a large
scale, I left this out of the analysis as well.
