Anyone with experience will tell you, gardens do not grow - no matter how talented the landscaper - without an effective growth strategy and a rich soil bed. The same can be said for planning, building and maintaining corporate data repositories - isolated databases don’t typically provide data-rich business intelligence. It’s an analogy that utility company San Antonio Water System (SAWS) understands well.

The selection of effective exploration targets is an important step in achieving success in hydrocarbon exploration. As a common practice, remote sensing and GIS technology are used to prepare baseline information like geological maps, structural maps, geological cross sections, thermal anomaly detection, hydrocarbon micro-seepage identification etc. to shortlist target exploration locations. Integrating geological cross-sections with the sub-surface structural trends leads to the identification of prospect areas.

It is a truism that Canada and the United States share the longest undefended border in the world. What is often overlooked in the observation, though, is that much of the border is water. More than 300 lakes and innumerable streams and rivers are part of or cross the international boundary, accounting for 40 percent of the 8,000-km (5,500 mi) long border. These lakes, rivers and streams are part of 15 distinct transboundary basins – from Alaska-Yukon border, to Coastal Mountain watersheds of British Columbia and Washington, stretching unbroken across the entire continent to the Great Lakes and St. Lawrence River and beyond to the coastal inlets of the Canadian Maritimes and New England.

If you are walking or cycling, and don’t want to (or are unable to) spend most of the time focusing on a screen, the use of mobile devices tends to be a frustrating experience. The same is true in bright sunlight or if your eyesight just isn’t good enough to see every detail on the mobile screen. The persisting problem of displaying information on the small screens of mobile devices is pushing both display development making use of sounds, gestures and the sense of touch.
Land Maintenance Actions in the Turin Province of Italy, A GIS Approach - Part 2

The reduction of land maintenance actions has determined a need for awareness about soil conservation issues. The main consequence is an increasing soil loss due to flash flood or similar phenomena. This issue needs a new approach leading to a continuous analysis and monitoring action. This part’s aim is to describe the main steps of the development of the GIS-based methodology to assess soil stability through GIS modelling. Specifically, soil physical structure has been studied by evaluating its aggregate stability. In order to follow a multidisciplinary approach data obtained from the laboratory analysis has been merged with topographical information and vegetation cover records.
