In February, 2006, Alberta Sustainable Resource Development
awarded MRF a contract to develop an ArcView
9.1 based application – The Visible Area and Analysis System (VisMap) – to support the management of wildfire
lookout tower network Visible Area Maps. These maps provided graphic
indication of various degrees of visibility at each lookout tower and
allowed staff to select aerial patrol routes, locate fires, and identify
blind areas. VisMap
application will be used as a decision support tool in ArcView environment to assist the planning of new
towers and optimize the lookout tower network to maximize the visibility
area.
The VisMap application has the following
capabilities:
·
VisMap is both analysis and mapping tool that can perform
visibility and best placement analysis and produce visibility maps and
reports.
·
Perform single tower or a group of towers visibility analysis and
mapping
·
Support flexible parameter configuration
·
Support multiple visibility classifications
·
Provide functions for best placement of lookout towers
·
Provide a 3D viewer of the visibility visualization
To date, MRF has completed the detailed system design, visibility
component development, and part of the 3D viewer development. The entire
application has been developed an ArcView extension.
Software used in the development of this project: MRF
Visibility COM component, ArcObjects, ArcMap 9.1, and ArcGIS
Spatial Analyst extension.
