Data Collection Remote sensing is the most commonly used method of counting trees. This technique stores data on the counted number of trees, which is then made accessible to the public. However, there are different methods of assessing this remotely sensed data: LiDAR, satellite images, UAV/drone images, and terrestrial photogrammetry. Examples Would you be happier

The Percentage of the Area That is Covered by Green Space
Data Collection The method of data collection mostly used in estimating the percentage of area occupied by green space are satellite imagery, aerial photography, or GIS mapping. Ground-truthing methods such as transects or quadrants are also used to measure the percentage of an area covered by vegetation. Once the data is collected, several methods can
Reduction in Carbon Emissions
Data Collection Organizations with databases that store data on carbon emissions include the National Energy Technology Laboratory, Carbon Dioxide Information Analysis Center, the Environmental Protection Agency, and the Intergovernmental Panel on Climate Change. These organizations use different methodologies to track and report carbon emissions data. The Carbon Dioxide Information Analysis Center uses a bottom-up approach,
Increase in Covered Miles of Roadway or Covered Surface Area
Data Collection The EPA collects and stores data on covered miles of roadway. The EPA uses a variety of methods to collect this data, including aerial surveys, ground-based measurements, and satellite imagery. Examples Protecting Water Quality From Water Runoff Some researchers have found that increasing the pavement surface area can increase stormwater runoff. A team
Reduction in Damage to Property or Infrastructure
Data Collection Data collection can be done by measuring the degree of destruction caused by stormwater runoff. There are a few ways to go about this; firstly, an observation can be done to estimate the damage that has been done to infrastructure and property in the aftermath of a storm. This can give an idea
The Concentration of Pollutants in the Runoff
Data Collection There are a few key methods for collecting data on the concentration of pollutants in the runoff: – Influent and effluent sampling: Sampling at the point where water enters and leaves a treatment facility can provide important data on pollutant concentrations. – Composite sampling: This method involves taking multiple samples over time and
Traffic Speeds and Speed Differentials
Data Collection Data on traffic speed can be collected from the U.S. Department of Transportation which records and stores data on traffic speed. USDOT collects data on traffic speeds from a variety of sources, including state and local law enforcement agencies, traffic engineers, transportation planners, and data from automated speed cameras and radar guns. The
Number of Collisions/Crashes
Data Collection The California Highway Patrol (CHP) is an example of an organization that records data on the number of collisions and crashes. Every year, the California Highway Patrol (CHP) investigates thousands of collisions and crashes across the state. This data includes information on the location, time, and type of accident, as well as any
Reduced Traffic
Data Collection Several organizations measure road traffic levels. These include the Federal Highway Administration (FHWA), the National Highway Traffic Safety Administration (NHTSA), and the Insurance Institute for Highway Safety (IIHS). Each organization has its method for measuring traffic levels, but all three use data from various sources, including state and local agencies, private companies, and
Reductions in Ambient Temperature
Data Collection Several online databases can provide data on temperature measurement. A weather station is also a good source that measures and stores data on measured ambient temperature changes . In addition, online temperature trackers are good sources of data collection . Examples Small increases in green spaces can offset temperature rise According to the
