green space is counted as one of the important bases of each city, especially great cities like tehran. with considering to vast application of urban green aria, the necessity of the managing these sources is felt more day-by-day. for proper managing each source, first the inventory of that source is taken into the consideration. regretfully so far there has been no comprehensive studios patter...

The use of remotely sensed imagery to generate land cover models is common today. Validation of these models typically involves the use of an independent set of ground-truth data which are used to calculate an error matrix resulting in estimates of omission, commission, and overall error. However, each estimate of error contains a degree of uncertainty itself due to 1) conceptual bias, 2) locat...

The Victorian Land Use Information System (VLUIS) produces an annual land information product for the state of Victoria. It comprises three important characteristics of land information: tenure (ownership), use (property type), and cover (physical surface). The land cover component is created using a remote sensing approach. Using MODIS EVI 16-day image composites (MOD13Q1) collected over 12 mo...

Department of Mathematics, University of Coimbra, Portugal Reference databases for the accuracy assessment of land cover maps are assumed to represent the true land cover in a set of selected locations. Although, the elaboration of reference databases through field visits or photo interpretation of aerial images is a hard and difficult task due to uncertainty in the assignment of the most corre...
