Statistical Methods To Partition Effects Of Quantity And Location During Comparison Of Categorical Maps At Multiple Resolutions, R. Gil Pontius
Statistical Methods To Partition Effects Of Quantity And Location During Comparison Of Categorical Maps At Multiple Resolutions, R. Gil Pontius
Geography
New generalized statistical methods to measure agreement between two maps at multiple-resolutions, where each cell in each map has a multinomial distribution among any number of categories, are presented. This methodology quantifies agreement between any two categorical maps, where either map uses fuzzy or crisp classification. The method measures the agreement at various resolutions by aggregating neighboring cells into an increasingly coarse grid. At each resolution, the method partitions the overall agreement into correct due to chance, correct due to quantity, correct due to location, error due to location, and error due to quantity. In addition, the method computes six …

The purpose of this study is to compile the best available long-term historical information on agricultural land use in Maine and to briefly analyze these data to develop a statewide description of Maine's land use history from the mid-1800s to present. Our emphasis is on compiling statistically based information and, in particular, land use data reported in the Census of Agriculture. Objectives were (1) to compile available statewide data on agricultural land and land cover (LULC) in Maine, 1850-1997; (2) to examine temporal and spatial patterns in the LULC of Maine; and (3) to discuss the implications of the major …

Between 1935 and 1992, the number of farms in the United States decreased from approximately seven million to fewer than two million. This change left a noticeable imprint on the landscape. Working farmsteads have been reduced to idle, desolate buildings, or in some cases there are no buildings left at all. To study this transformation, black and white air photographs from 1950 were compared with 1990 air photographs. Also, plat books and ground checks in four townships in Watonwan County in southwestern Minnesota helped document changes. Farmsteads were abandoned or demolished because people began to find they could not economically …
