Model Documentation

Rollout Modeling Packages:

Rollout modeling packages contain models and results used by the ILAP project for projecting landscape conditions for each model region for forests and arid lands. The Path models provided have ILAP's spatially defined, modeling strata.

Only the Region3 packages contain the multipliers needed for rerunning Path models' modeling strata. For Region6, if the user needs to modify models (e.g. multipliers, states or transitions) or the spatial conditions described within each modeling strata (e.g. ownership boundaries, PVT classes) for rerunning models, they should refer to the prerollup modeling folder found on this site.

Pre Rollup Modeling Packages:

Pre Rollup modeling packages contain the VDDT models database (Db) and a template Path models Db. If the user needs to modify models (e.g. multipliers, states or transitions) or the spatial conditions described within each modeling strata (e.g. ownership boundaries, PVT classes) for rerunning models, they should refer to the packages found in this folder. The user will then need to re-rollup the models into a landscape-ready format. This path modeling rollup tutorial provides instructions on the rollup process.
