This project involves scraping temperature data from the DarkSky Forecast API, plotting the data from six cities using the Seaborn and Plotly data analysis libraries, and showing current weather radar data on a map marked with the six cities.
The web map uses open source software and real-time weather radar data. (Click on the "layers" icon in the upper right corner of the map to view the different basemaps.)
To view the code used to scrape data from the Dark Sky Forecast API and process it, see the Jupyter Notebook for this project. (The boxplot in the Jupyter Notebook uses the Seaborn library rather than Plotly.)
Interactive Plotly Boxplot
The HTML page for this project uses a Plotly boxplot which allows the user to hover over the boxes in the plot to see the exact values of the relevant statistics.
For this time period (6/7/16 - 7/6/16), the data show that the daily high temperature for Austin has the smallest fluctuation changing only 12.88 degrees over the 30-days compared to Los Angeles, which has the largest range of 28.10°F.
Austin also has the highest mean maximum temperature over the period, indicating that not only is the daily high temperature relatively consistent, but also it just plain hot in Austin in June. Seattle has the lowest daily high temperatures of the six cities considered, which is not surprising given the generally cloudier and rainier climate of the Pacific Northwest, even in June.
This project invovled classifying remotely-sensed near-infrared imagery to quantify land loss due to Hurricane Irene.
Technologies Used: ENVI and ArcGIS
Data Sources: Google Earth and the North Carolina Department of Transportation (NCDOT)
Overview & Contextual Map
This study used remotely-sensed near-infrared aerial imagery to ultimately measure Hurricane Irene's changes in vegetation, water and land areas on Hatteras Island, NC.
The map to the left shows Hatteras Island, North Carolina, highlighting two areas - Pea Island and Rodanthe - where Hurricane Irene washed out sections of Highway 12 on August 27, 2011 disconnecting the island from the rest of the Outer Banks and mainland. Hatteras Island was accessible only by ferry boat until a temporary bridge was installed on October 10, 2011.
Satellite Photograph - Before Hurricane Irene
Left is a Google Earth satellite image of the Pea Island area of Hatteras Island before Irene hit on August 27, 2011. The road is shown in grey. The Atlantic Ocean is to the right (or east), the Pamlico Sound is to the left (or west) in this image.
Satellite Photograph - After Hurricane Irene
This Google Earth satellite image of the Pea Island area taken after Irene hit shows a new inlet that connects the Sound and the Atlantic. As Irene moved northward, it passed over Pamilico Sound which ultimately caused floodwaters to flow from the Sound-side of the island toward the Atlantic side washing out Highway 12 in several locations.
Near-Infrared Aerial Image of Hatteras Island, NC
Left is a remotely sensed aerial image taken via airplane on August 2, 2011 of the Pea Island area of Hatteras Island before Irene hit on August 27, 2011. The highway is shown in bright red and green vegetation is shown in a maroonish red color.
Classification of Land and Water Types Before Hurricane Irene Hit
Since the goal of this study was to quantify changes in water and land areas as a result of Hurricane Irene, my approach involved classifying both the before and after near-infrared images, then determining which areas changed classes between the two images.
This classification image shows the Pea Island area before the hurricane hit. Water from Pamlico Sound is colored cyan, vegetation is dark blue, the road is green, sand is red, a mixture of sand and vegetation is pinkish-grey and the Atlantic Ocean waters are bright pink and yellow - the bright pink showing the swash zone where the waves are breaking and the water is turbid and full of suspended sediment.
