Tobler (1965) introduced bidimensional regression to the research field of geography in 1965 to provide a method for estimating mapping relations between two planes on the basis of regression modeling. The bidimensional regression method has been widely used within geographical research. However, the applicability in assessing the degree of similarity of two-dimensional patterns has not much ex...

  Application of gepraphic information system and image processing in evaluation of surface runoff of a watershed in recent years has increased greatly. In the study , the runoff curve number map was prepared using geographic information system (GIS)and Landsat Sattelite Images (ETM+)for two watersheds of Mansourabad in southern Khorasan province and Navroud in Gilan province based on the facto...

today, extensive improvements in fields of soil mapping have increased the purity and accuracy ofsoil maps. usual mapping methods moreover depend on skills and experience of surveyor inidentifying and delineating the boundaries, also need the high cost and time consuming that face thesoil mapping with restrictions. in this study, aerial photographs with 1/40000 scale were used in orderto prepar...

flood risk zonation is necessary to control and predict the amplitude of flood damage.the purpose of this research is to evaluate the rate of flood risk vulnerability and the flood damage assessment in tabriz. specific variables of this study are land use , population density , river beds , slope classes residential density , cn coefficient , runoff coefficient , open spaces and old buildings.m...

This paper discusses the process of identifying stakeholders for the evaluation of health information systems through a map. Defining the multiplicity of stakeholders associated with a new system as well as the nature of their relationships is an important aspect of evaluating any intervention. We report a study of the Electronic Prescription Service (EPS) in primary care in England. We describ...

Three sections of the same distance education class completed a series of Web-based concept map assessments using one of two methods. Open-ended maps applied in section 1 led students to conduct more relational thinking overall, but variance in map items was very high introducing more subjectivity in scoring. Pre-selected term mapping applied in sections 2–3 led students to correctly classify m...
