 This is my "To do list" and "Scrap drawer" where I keep fragmented half baked ideas for articles and scraps. When I begin to focus on one more seriously, I move it to one of my other sandboxes.

Patricia Gober is a geographer, professor of geography at Arizona State University, and was the president of the American Association of Geographers (AAG) between 1997 and 1998. Her research interests include "urban planning and design, sustainability, and the connections among food, water, and energy."

Education and field
Gober earned their B.S. in geography in 1970 from the University of Wisconsin-Whitewater. She earned her M.A. in 1972 and Ph.D. in 1975, both in geography from The Ohio State University.

Honors and awards

 * Presidential Achievement Award Recipients, American Association of Geographers, 2011
 * Prince Sultan bin Abdulaziz International Prize for Water, 2008
 * Faculty Research Achievement Award, Arizona State University, 2009
 * Honorary doctorate of science, Carthage college, 1998

Arizona State University Pat Gober Water Prize
The "Pat Gober Water Prize" was created to recognize Gober's contributions to Arizona State University in 2019. It awarded annually by the ASU School of Geographical Sciences and Urban Planning to students who win a research proposal competition related to water-related research. The award is $1,500, and can be used for research and travel expenses.

Getis-Ord Gi*
Getis-Ord Gi* (pronounced "Getis-Ord G-star") is an extension of the Getis-Ord Gi statistic, which is used to identify statistically significant hotspots and coldspots in a spatial dataset. The method was developed by Arthur Getis and J. K. Ord in 1996 to improve the original Gi statistic.

The Gi* statistic is calculated using a similar formula to the Gi statistic but with an additional term that considers the spatial autocorrelation of the data at different distances. The formula for the Gi* statistic is:

Gi* = (Xi - Xbar) / S * Σj(wij * Xj - Xbar) / √(Σj(wij))^2 / N

where N is the total number of locations in the dataset.

The numerator of the Gi* formula is the same as the Gi formula. At the same time, the denominator represents a measure of the expected value of the sum of the weights for each location. The denominator considers the spatial autocorrelation of the data at different distances and is used to standardize the numerator.

The Gi* statistic produces a z-score, which can be used to determine the statistical significance of a hotspot or coldspot. A positive z-score indicates a statistically significant hotspot (i.e., a location with a high value surrounded by locations with high values), while a negative z-score indicates a statistically significant coldspot (i.e., a location with a low value surrounded by locations with low values).

The significance of the z-score can be determined using a p-value or a critical value. A p-value represents the probability of obtaining a z-score as extreme as the observed value, assuming that the null hypothesis (i.e., no spatial clustering) is true. A critical value represents the threshold above which the z-score is considered statistically significant.

The Gi* statistic can be used to identify hotspots and coldspots in various spatial datasets, such as crime data, disease incidence data, and environmental data. The method is particularly useful for identifying spatial patterns that may be missed by other methods and for generating hypotheses about the underlying causes of spatial clustering.



The laws of geography are a set of scientific laws defining spatial data characteristics.

The concept of laws in geography is a product of the quantitative revolution and is a central focus of quantitative geography. Their emergence is highly influential and one of the major contributions of quantitative geography to the broader branch of technical geography. The discipline of geography is unlikely to settle the matter anytime soon. Several laws have been proposed, and Tobler's first law of geography is the most widely accepted. The first law of geography, and its relation to spatial autocorrelation, is highly influential in the development of technical geography.

Some have argued that geographic laws do not need to be numbered. The existence of a first invites a second, and many are proposed as that. It has also been proposed that Tobler's first law of geography should be moved to the second and replaced with another. A few of the proposed laws of geography are below:

The Terrain Ruggedness Index (TRI) is a quantitative measure used in geography and geomorphology to assess the roughness or ruggedness of a terrain surface. It is a tool commonly employed in fields such as hydrology, ecology, and geology to characterize landscapes and understand their influence on various processes and phenomena.

==Calculation The Terrain Ruggedness Index is typically computed using elevation data, such as digital elevation models (DEMs) derived from satellite imagery or ground-based surveys. The index is calculated based on the variability of elevation within a defined area, with higher values indicating greater ruggedness or roughness.

==Interpretation The Terrain Ruggedness Index provides a quantitative measure of the variability in terrain elevation within a specified area. Higher values of TRI indicate rougher or more rugged terrain, whereas lower values suggest smoother or flatter landscapes. This index is particularly useful in landscape analysis, ecological studies, and terrain modeling, where understanding terrain complexity is essential.
