Forestry Tools

What open source geo products have tools that may be specially useful for foresters and resource managers? A discussion started on the QGIS-User list led to starting this page.

General Categories

What types of workflow or features are required for managing forests? Think broad, and then we can get into specifics in each category.

GPS traversing

General data capture to record paths, boundaries and locations using GPS.

Ability to turn it on/off
Ability to capture multiple types of features

Design and capture

Block, road, treatment areas

Connect various attributes to GPS collected information
Custom input forms

Mobile map platform

Following current and planned locations

Map layer control on/off
Zoom, pan, query
Basic feature calculations - length, area, sum attributes
Show GPS,
Auto panning map via GPS
Edit stand boundary and sale boundary shapefiles

Inventory collection and analysis

Backend database and front end collection of inventory details

Offline database, with inventory schema
Platform for mobile data collection and input
Auto form generation for particular feature types
Syncing with master db when back online
Generation of reports such as stand tables, stocking tables, and associated information.
Predict future devlopment of standing volume etc.
Perform economic analysis with specifed user input
Ability to calibrate based on localized growth and yield tables.
Support for a varity of cruise methods. (Point, fixed plot, etc.)
Support for a variety of volume tables. (Scribner, Doyle, International 1/4, Carlson Method).

Sample plot reconnaissance and survey

Generate plot schemes based on sampling intensity needs, and other input criteria (random vs. systematic, etc).
- Zig Zag schema based on tract width/length.
Relate/connect plot/survey locations with inventory to allow for plot re-use in subsequent more intensive sampling efforts.

Terrain/slope/area/distance computation and measurements

Ability to work in, use and display acres/hectares rather than just sq ft/m and miles/km.

Time-analysis

What has the development of the different stands been over the years?
Compare pictures taken previously to visualize changes
Linking stands over time (splitting, changing borders)
Change detection
- DTclassifier plugin

Surveying

From old style surveying techniques, calculate positions of corners/markers in GPS datum
