Flexible Soil Model Maps Remote Areas

innovlogo…from Innovations Report

“Soil scientists often face the dilemma of wishing to study soil in remote areas because they are ideal places to study soil formation and distribution under natural conditions, but mapping them requires a huge investment of time and resources. Computer-based models offer an efficient alternative. Researchers used ArcGIS geodatabase software to develop the Remote Area Soil Proxy (RASP) modeling technique to predict natural occurrence of soils in remote areas.

“Bruce Frazier and Richard Rupp of Washington State University and Toby Rodgers and Crystal Briggs of Soil Survey conducted this work in the Pasayten River watershed in north-central Washington. Their results are reported in the summer issue of Soil Survey Horizons. Data were collected from dominant landscape facets accessible by or near trails, and soil formation was modeled using surrogates for the soil forming factors.”

The Need for Comprehensive 3D City Models

stu_rich22Stu Rich has a new post on his Spatial Explorations blog titled “The Need for Comprehensive 3D City Models (Part 1)“.  Here’s an excerpt:

“On my recent trip to Vancouver to speak at the GeoWeb 2009 conference, however, I was inspired by Thomas Kolbe’s work on CityGML to think more about collections of buildings and how they work together in an urban environment. As we move to this city and regional scale, the level of granularity at which we model our buildings has big implications on scalability, performance, and the tool sets that we use for visualization and analysis.  For the purposes of our discussion here, let’s define a “City” is a reasonably large collection of buildings in a condensed area. This city might be a traditional municipality like Philadelphia or Chicago, it might be a military city like Langley Air Force Base, or it might be a college campus like Boston University.”

Looking forward to reading Part 2, Stu!

University of Arkansas gets DOE Grant for Water Resource Simulation Model

…from New Technology Magazine

“The Office of Fossil Energy’s National Energy Technology Laboratory (NETL) has selected nine new projects targeting environmental tools and technology for shale gas and coalbed methane (CBM) production. NETL’s goals for these projects are to improve management of water resources, water usage and water disposal, and to support science that will aid the regulatory and permitting processes required for shale gas development.

“University of Arkansas, Fayetteville, Ark.—The ultimate goal of this project is to develop a water management decision-support system by modifying and integrating a state-of-the-art water resource simulation model with a modern enterprise geographic information system (GIS). This will provide a science-based tool that can be used to support development of energy resources in the Fayetteville Shale region of Arkansas. (DOE share: $636,467; recipient share: $179,517; duration 24 months)”

Spatial Analysis Aids Relocation of Javanese Rhino

…from The Jakarta Post

“The study was aimed at assessing the geology, soil type and proximity to water in order to find suitable areas for the planned relocation of the Javanese rhino.

“The proposed areas are adjacent to Gunung Honje, Gunung Halimun, Masigit Kareumbi and Leuweung Sancang, all of them close to the Ujung Kulon area on the western tip of Java Island.

““The spatial analysis suggests there is good possibility of an area on the Ujung Kulon peninsula and on Gunung Hone suitable for the Javan rhino,” the study said.”

Spatial Analysis of Social Facts

By Claude Grasland

“A tentative theoretical framework derived from Tobler’s first law of geography and Blau’s multilevel structural theory of society.

“This document presents an attempt to build a theoretical framework for the spatial analysis of social facts, derived from Tobler’s first law of geography (‘Everything is related to everything else, but near things are more related than distant things’) and Blau’s theory of macro sociology and multilevel structural analysis. At individual level four basic times of position and interaction are defined (geographical/sociological and discrete/continuous). It is then necessary to discuss the effects of scale aggregation and time dynamics on the elementary levels of position and interaction. This part is illustrated by examples about airflows between world cities in 2000 and euro coins diffusion across borders between 2002 and 2007.”
