IRM utilizes the ArcGIS 8.1 geographic information system combined with image processing programs such as ERDAS and OrthoGIS to make sense of large multifaceted and complex land management issues.
IRM has the capability to efficiently and accurately map forested landscapes and create high quality maps which provide answers to our clients' spatial questions.
IRM also uses GIS to increase the effectiveness of its crew in the field. Accurate mapping and the "rubber sheeting" of color aerial photographs allows our field foresters and biologists to more effectively conduct their field studies.
The Trimble system is capable of sub-meter accuracy and can be used to navigate to points in the field using real time correction. IRM's field GPS technicians are highly experienced and as a result they ensure a quality-mapping product.
Services:
- Vegetation Typing
- Custom Aerial Photography
- Resource Mapping (roads, water, noxious weeds, etc.)
- Fire Regime and Behavior Mapping
- Spatial Analysis for Harvest Layout, Road Design, and Fuel Reduction Projects
- Ortho-Rectification
Pacific Forest Trust - Road Maintenance Inventory and Mapping
In the spring of 2005, IRM conducted a road maintenance inventory and mapping project for the Pacific Forest Trust on 7,000 acres of managed forest near Corvallis, Oregon. IRM designed a custom data dictionary, which dovetailed with the client's GIS database.

IRM field technicians mapped over 75 miles of roads using our Trimble PRO XR GPS receiver. Attribute data was collected for roads, culverts, stream crossings, bridges, mass wasting sites, and other pertinent features.
The position data was post differentially corrected using the Trimble Pathfinder Office software and was exported into ESRI shapefile formats for incorporation into the PFT GIS database. This highly accurate and complete dataset will allow the PFT to effectively and efficiently manage the road system and prevent damage to non-timber resources as a result of poor maintenance. |

Double E Northwest - Forest Land Management Mapping Project
|
IRM uses its GIS to effectively manage a 3,000 acre tract of forestland, in the Oregon coast range. The GIS is used for the following:
Harvest Unit Maps;
Stand Inventory Maps;
Endangered Species Compliance and Management;
Structural Diversity Planning; and
Road Maintenance Monitoring.
IRM uses its Trimble PRO XR receiver to collect data for the GIS, in order to maintain an up to date spatial database. |
GIS is a powerful tool for analysis of harvest layout and facilitates protection of site resources. |
Willapa National Wildlife Refuge - Road Maintenance Inventory and Mapping
In the Spring of 2005 , IRM conducted a road maintenance inventory and mapping project for the Willapa National Wildlife Refuge on 4,000 acres of previously managed forest on Long Island in Willapa Bay, Washington. IRM designed a custom data dictionary, which dovetailed with the client's GIS database. IRM field technicians mapped over 25 miles of roads using our Trimble PRO XR GPS receiver.
Attribute data was collected for roads, culverts, stream crossings, bridges, mass wasting sites, and other pertinent features. The position data was post differentially corrected using the Trimble Pathfinder Office software, and was exported into ESRI shapefile formats for incorporation into the Willapa National Wildlife Refuge GIS database.
This highly accurate and complete dataset will allow the Willapa National Wildlife Refuge to effectively and efficiently manage the road system, prevent damage to non-timber resources, and help them decide which roads should be abandoned.
