- 35. YOUR TURN Download images and shapes of the DC area from here: https://goo.gl/UqgNDx
- 36. WHAT WE WILL ACCOMPLISH: 1. Open and View Satellite Imagery of DC a. Combine spectral bands to form a “True Color” RGB image of DC b. Apply Brightness/Contrast Enhancement c. Zoom in/out of the map 1. Create a “False Color” image using the Near Infrared band 1. Identify Wet areas using the Normalized Difference Pond Index (NDPI) a. The same method can be applied to get the ND-Vegetation Index (NDVI) 1. Open and View DC Features as ‘shapefiles’
- 37. OPEN QGIS You might have already downloaded QGIS, if not, go to https://goo.gl/2K90hr OPEN QGIS. Different computer types might show different versions.
- 38. ADD IMAGES Click on the square ‘add raster layer’ button on the left panel to add images also called ‘rasters’ to the map
- 39. NAVIGATE TO WHERE YOU’VE DOWNLOADED THE SAMPLE DATA Select the files that end in “B2”, “B3”, “B4”, “B5”, and “B6”
- 40. BAND 2: BLUE BAND 3: GREEN BAND 4: RED
- 41. RED-BLUE-GREEN “TRUE COLOR” COMPOSITE Open the “Toolbox” Type in “Composite” in the search box
- 42. OPEN THE COMPOSITE FILE Type “32618” in the “Filter” box, then click ok. This will make sure your image shows in the correct location on the map.
- 43. RED-BLUE-GREEN COMPOSITE OUTPUT It looks very dark! Apply Contrast/Brightness enhancement

- 51. CREATE NEW INFORMATION USING BAND CALCULATIONS The raster bands are similar to matrices. They can be added, subtracted, multiplied and divided. Calculations can be performed over the Landsat data to extract meaningful information. Open the ‘Raster Calculator’ To identify water bodies and wet areas, we will calculate the Normalized Difference Pond Index (Lacaux 2006)
- 52. THE NORMALIZED DIFFERENCE POND INDEX (NDPI) NDPI was created in response to several indices aimed at identifying small water bodies. When applied to Landsat data the formula to calculate NDPI: (Band 6-Band 3)/(Band 6 + Band 3) This formula normalizes the differences between the shortwave infrared band, and the green band, focusing on open water, wet and swampy areas.

Editor's Notes
- No experience in fashion or technology. But they were passionate about fashion, and letting other women enjoy fashion affordably. The idea was a good one.

- This slide can be used as a background before the presentation begins.
- I’d love to clip the photos into circles.
- Bear Glacier is an outlet glacier of the Harding Icefield in Kenai Fjords National Park, Alaska. Glaciers form when fallen snow compresses into an ice mass over many years; the process usually takes centuries. The ice then flows to lower elevations. Since Bear Glacier and many other remote glaciers are largely inaccessible, satellite images provide important insights into how they change over time. During the last 100 years in Alaska, the annual average temperature has increased by about twice the global annual average temperature change. A temperature increase like this can change the regular pattern of glacial advance and retreat. Between 1950 and the 1990s, Bear Glacier retreated 1.55 kilometers (1 mile). Small icebergs were calving into a lagoon that had developed. By 2004, the glacier’s floating terminus calved, causing an additional 2 kilometers (1.25 miles) of retreat. Between 2000 and 2007, the terminus retreated another 3.5 kilometers (2 miles). Large icebergs now float in the lagoon, visible in the Landsat images as light blue spots in the water.
- California’s San Joaquin Valley is one of the world’s most productive agricultural regions. Much of that productivity depends on the availability of water for irrigation. Recent prolonged droughts in California have underscored the importance of accurately monitoring changes and trends in water use in order to make well-informed water management decisions. ET is the combined effect of evaporation from the soil and transpiration from plants. ET is a major part of the hydrologic budget of a watershed. It varies with different climate, vegetation types, and land use. With ET estimates derived from satellite data, scientists at EROS estimated how much water is being used to water crops. They used a computer model that incorporates Landsat imagery, including the Landsat 8 thermal band, along with climate data to estimate ET for every Landsat scene of the San Joaquin Valley from 1984 to 2014. They then used the ET results along with precipitation and runoff data to create maps that show water use in the valley over that 31-year time period. The maps show seasonal crop water use in millimeters with enough detail to show individual fields and reveal which crops are using the most, or least, water.
- Lake Pontchartrain covers the northern part of these Landsat images. The curvy dark line is the Mississippi River as it meanders past New Orleans. The dark straight lines are canals, built for flood protection and as an aid to water navigation. The September 7 image shows New Orleans days after Hurricane Katrina struck. The flooded areas are dark, giving the city a bruised appearance. A straight vertical line separates a dark flooded area of the city from the light green-pink unflooded area. The floodwaters appeared to have stopped at the 17th Street Canal. This canal failed but the west dike held, keeping that part of the city from flooding. Floodwater from the Gulf of Mexico made its way to Lake Pontchartrain, which then flooded this part of the city with an 11-foot storm surge. Water entered the canals but the canal walls did not overtop. The walls failed when water had only risen part of the way up the wall. When these canals broke, water from Lake Pontchartrain poured into these neighborhoods. By September 7, the city had started to drain. Pumps worked to return the water to Lake Pontchartrain. About 380 cubic meters (100,000 gallons) of water were pumped out of the city every second.
- Glen Canyon Dam on the Colorado River was completed in 1963. It creates Lake Powell, which ebbs and flows depending on upstream precipitation. Lately, it’s been more ebb. Glen Canyon National Recreation Area encompasses Lake Powell and is visited by more than 2 million people per year. Since 2000, the Colorado River Basin has been in an extended drought. In over 100 years of record keeping, the basin has had its lowest 16-year period of inflow from rain and snowmelt. During 2000–2015, the inflow of water into Lake Powell was above average in only 3 years. As a result, Lake Powell was at less than half of capacity in 2015. Droughts combined with a rising population means water sustainability will only become more of a challenge. In addition, hydropower capacity at Glen Canyon Dam could be reduced. Severe droughts are a regular part of the climate variability in this region; however, droughts are expected to become more severe in the future. Referred to as the “bathtub ring,” this pale outline shows when the lake is below capacity. Calcium carbonate and other mineral compounds, many of them various salts in the water, attach themselves to the sandstone and leave behind this white mark. The top of the white mark is the high water mark. The only time the bathtub ring is not visible is when the lake is completely full.
- The patches of red in these false-color Landsat images are the forests where monarch butterflies spend the winter. Starting in late summer and fall, monarchs in the United States and Canada migrate south to Mexico. Some travel up to 3,000 miles. The delicate insects are capable of flying 50–100 miles a day. Cold weather drives the monarchs to head south to hibernate for the winter. They head for the only habitat suitable for their hibernation, oyamel fir (Abies religiosa) forests. These forests grow in only small areas of mountain tops in central Mexico, about 3,000 m above sea level. The monarchs usually cover whole trees as they keep each other warm. The short needles of the oyamel fir allow the butterflies to cluster together better than they could on flat-needled cedars or long-needled pines. The oyamel forests provide a microclimate for the butterflies. Temperatures stay above freezing. If the temperatures were lower, the monarchs would have to use their fat reserves. The humidity provided by the forest also keeps them from drying out. The monarchs stay in Mexico from about November to March. In the spring, they fly back north. On the way, they lay eggs on milkweed. These eggs hatch into caterpillars, who devour the milkweed leaves, then metamorphose into monarchs. These monarchs live about 5 weeks or so. Apr. 1, 2016, Landsat 8 (path/row 27/46) — Pelon site, Monarch Butterfly Biosphere Reserve, Mexico Monarch Butterflies, Mexico Degraded Habitats Global Forest Maps Lomas de Aparicio NDVI Pelon Monarch Value The monarch migration is an endangered phenomenon. Logging in the overwintering sites in Mexico reduces the area available for the monarchs. The Monarch Butterfly Biosphere Reserve, established in 1986, is intended to protect the overwintering areas. But studies have shown that deforestation has occurred within the reserve. Some of that deforestation can be tracked from space with Landsat imagery.Landsat sensors use infrared reflectance. One of the wavelengths of light they use is called near-infrared. Actively growing vegetation reflects this wavelength, so when this wavelength is assigned the visible color red, vegetation is displayed as red in these false color images. As you take a closer look at the zoomed in areas in the other sections, watch for gray patches in areas that were once red. This indicates a degraded forest. Not all of the reduction in the monarch population can be attributed to oyamel forest loss in Mexico. In the United States, expansion of agriculture and herbicide use are reducing the milkweed that the caterpillars need. Extreme weather conditions have also been harming the monarchs. Satellite imagery continues to be useful in tracking the monarch population in these overwintering sites and can help recover this remarkable migration. These close-ups show another core zone area of the reserve called Pelon. Forest disturbance is most visible in the 2000 image. Later Landsat images reveal some red filling in in this area. In the Landsat imagery, red indicates any actively growing vegetation, so it may not be the tall trees of oyamel forest recovering yet.
