The historic calibration is typically done with land-use maps with a ten years interval as indicated in the figure. The reason is that production of land-use maps is elaborate and time-consuming, because it is usually based on visual interpretation of remote sensing data in combination with other datasets. This also leads to temporal inconsistencies. The sporadic availability and temporal inconsistencies hamper the historic calibration of land use change models

Two major research issues. Improving calibration implies defining what improvement means and how it can be measured.
Explain that a method is being developed that uses spatial metrics that describe characteristic aspects of urban form and structure. Parameters in the model are tuned in such a way that the simulated patterns of urban growth, as described by the metrics, match the patterns observed in remote sensing imagery

then we define some spatial units based on an intersection of a road network with recent moland land-use data
