HEC-RAS is designed to perform one-dimensional hydraulic calculations for a full network of natural and constructed channels. HEC-RAS has been developed for the U.S. Army Corps of Engineers. It is also available for download and use by individuals outside of the Corps of Engineers without charge. Download learning tutorial on HEC-RAS from following Link:
CO2 emission can be measured using LIDAR. Following are the details of projects and datasets for CO2 Emission:
The Vulcan Project: The Vulcan Project is a NASA/DOE funded effort under the North American Carbon Program (NACP) to quantify North American fossil fuel carbon dioxide (CO2) emissions at space and time scales much finer than has been achieved in the past.You can use Vulcan Project’s Google Earth Application for CO2 Emission from Fossil Fuel 2002. It requires Google Earth Plugin.
Experimental Advanced Airborne Lidar (EAARL) and Airborne Lidar Processing System (ALPS) Software: The Experimental Advanced Airborne Lidar (EAARL) system used in this data acquisition effort is uniquely suited to capturing sub-aerial and submerged topography in the same overflight. The voluminous data sets acquired from the EAARL surveys are processed using a Linux-based, custom-built system, Airborne Lidar Processing System (ALPS), developed in a NASA-USGS collaboration. This processing system enables the systematic creation of highly detailed submarine and sub-aerial topographic maps for use in ecological models and environmental stewardship. You can use also USGS- NPS-NASA EAARL Data.
Extract the zipped file of contourmatlab to required directory.
Open matlab and set your current directory of matlab to the extracted folder.
Change the data in data.xls file to your own data. Remember that first column is latitude, second is longitude, both in decimals. While third column is value which you want to plot in contour. Same Latitude and Longitude should not repeat in rows. For good contour plot, given data should be well distributed.
In matlab command line, type: plotcont
Your contour will be plotted.
To change the region of your plot or spacing of the plot data, you must edit plotcont.m file.
You can use this file to plot the elevation contour of given region. All you need is to take latitude, longitude and elevation data for the required region. You can use google earth for this or if only elevation data is required then use online elevation profile.
