| − | Typical spatial extent of application
| + | |
| − | The normal spatial application level of ETÇAP is the forest level with various stands. Yet the spatial resolution of the model is the stand, the smallest identifiable unit of forest area.
| + | |
| − | Forest data input
| + | |
| − | ETÇAP input information are inventory data that can be imported from files with .xls or .mdb extensions with a specific format.
| + | |
| − | The input data required depends on the characteristics of the stand. Three groups of data are needed for the model; the current area of the stands generated by a GIS software, current status of each stand measured with inventory sheets for per area growth and yield characteristics (in each plot: the plot size, diameters of all stems, ages of some stems, age and dominant height for a number of stems, and ten-last-years growth for some trees) and the other support tables (volume table, empirical yield table, site index table, product assortment table and financial value table) characteristics
| + | |
| − | In order to allow spatial layout of a harvest schedule for visualization and generation of maps, compartments, forest stratifications and analysis areas have to be set and related to each polygon (a sub-compartment =stand) with geographic files

| + | |
| − | • Design: ETÇAP model is designed to create a forest management plan with management objectives and constraints. The objectives could either be achieved by simulating the forest conditions into future (planning horizon) or achieved by finding the best combination of prescriptions through mathematical optimization approach. As well, spatial lay out of management choices is determined with combinatorial optimization techniques to generate a management plan implementable on the ground.
