Precise positing – the ability to know your location from a latitude – longitude, or X-Y location, on the earth and how high above mean sea level your feet are firmly planted on the ground to within centimeters. Is this type of information becoming a wave of the future or am I just a geek about it? When I go to the gym in the morning, I am strapped with my fitbit and my Polar Heart Rate monitor which provide me with information about my speed, distance, x-y-z location, and heart rate while I train. Not to mention, providing me with an avenue to publish my activity via social media to participate in competitions with friends. J This type of information can be plotted on Google Earth to see where I have traversed, although, sadly enough when I workout at the gym my traverse is a “dot” as I barely change in x and y or z (height) for that matter, when on a treadmill. On the other hand, when I am outside, my walk changes in all three dimensions which can be displayed quite nicely in Google.

On August 20th I posted a blog on a distinguished Intermap employee “Mr. Robert Crawford” who has been in the remote sensing business for nearly four decades. The blog had a snipped of a newspaper article from “CORPUS CHRISTI CALLER dating back to February 18, 1977.
Flood inundation models provide predictions of the depth and extent of a potential flood. This information is then used in the assessment of risk to life and property in the floodplain (e.g. creation of hazard and risk flood maps), and to develop mitigation and restoration strategies. We have seen over the past decade significant advances in flood inundation modeling due to advances in hydrological modeling software coupled with the availability of more accurate elevation data. But how is the accuracy flood hazard and risk maps established? (more…)
While at the ASPRS “Imaging and Mapping for Disaster Management: From the Individual to the Global Community” I attended many excellent talks about remotely-sensed solutions for disaster management. An excellent presentation, given jointly by Rohini Swaninathan (NASA Intern) and Pedro Juan Rodriguez Rivera, reported on the use of freely available, satellite-based, remote sensing technologies and GIS solutions to help identify hotspots of large fires burning in Mexico. This project was prompted because of the 2011 fire in Coahuila, Mexico, where nearly 100,000 hectares of land were burned, costing the Mexican government to spend over 19 million US dollars. This fire represents the largest amount of land burned in a single fire in Mexico and took weeks to be extinguished.
