ALCESİ
FAQ
What are the Minimum Computer and Internet Requirements for running ALCES?
The following descriptions provides the ALCES user with the minimal system and hardware requirements to run ALCES:
- Windows CE-based terminals
- Windows CE-based Handheld Professional devices (H/PC Pro)
- 32-bit Windows-based PCs running Windows NT.3.51, Windows NT 4.0, or Windows 2000 Professional
The minimum requirements for the 32-bit Windows are:
- Pentium IV running at a minimum of 1 ghz
- Windows 95,98, ME, Windows NT , 2000
- 8 MB of RAM for Windows 95, 32 MB for NT, 64 for all others
- 20 MB of available hard disk space
- VGA or higher resolution video adapter
- High-density 3.5-inch disk drive
- Network interface card (NIC) using the TCP/IP protocol
- Microsoft serial mouse or 100 percent compatible
The information provided above are the minimum requirements. We recommend having at least a Pentium 4 at 1 ghz with 512MB memory and a 16MB video card.
Does ALCES come fully loaded with landscape-specific data?
Generally, no! Although the ALCES model is complete in terms of its ability to approximate all relevant landuses and natural disturbances, it is the responsibility of the ALCES II user to populate the model with the following data:
1. Initial landscape composition
2. Natural disturbance regime metrics
3. Future landuse trajectory information
4. All metrics (width, length, area, lifespan) of each landuse footprint
Is ALCES a spatial or aspatial model?
ALCES is a spatial model because it stratifies the landscape into multiple geographic strata (generally 20) and tracks a full suite of landuse footprints and natural disturbance regimes separately within each landscape strata. ALCES is not a spatially explicit model, however, and does not keep track of the exact geographic (latilong) location of either landscape types or landuse footprints. That said, the ALCES user has the option of using MapNow, an application completed in 2006, that spatially maps ALCES output into a spatially explicit mapping format.
