Welcome to the United States Geological Survey, or USGS for short! The USGS is responsible for providing scientific data about natural hazards, the health of our ecosystems and environment; and the impacts of climate and land-use change. Their scientists develop new methods and tools to supply timely, relevant, and useful information about the Earth and its processes. As a new hire, I will be helping them out with an exciting new project!
The USGS is interested in building a new set of tools that will allow them visualize their earthquake data. They collect a massive amount of data from all over the world each day, but they lack a meaningful way of displaying it. Their hope is that being able to visualize their data will allow them to better educate the public and other government organizations (and hopefully secure more funding..) on issues facing our planet.
-
Create a new repository called
leaflet-challenge. Visit my Github io!! Leaflet-Challenge Github io -
Created a directory for the Leaflet challenge, using the folder names to correspond to the challenges: Level 1 and Level 2.
-
This homeworks utilizes both html and Javascript as main files to run for analysis.
- Leaflet
- GeoJSON
- Map obects
- Tile layers
- Choropleth
- Config.js
- CSS
- HTML
- Javascript
My first task: visualize an earthquake data set.
CHALLENGE COMPLETE!!
1. Get the data set from USGS site
- Visited the USGS GeoJSON Feed page and pick the past 7 Days data set to visualize the last earthquake.
- Used the URL of this JSON to pull in the data for my visualization.
-
Importing & Visualizing the Data
Create a map using Leaflet that plots all of the earthquakes from your data set based on their longitude and latitude.
-
Data markers reflect the magnitude of the earthquake in their size and color.
-
Earthquakes with higher magnitudes appear larger and darker in color.
-
Included popups that provide additional information about the earthquake when a marker is clicked.
-
Created a legend that will provide context.
-
Satellite Overlay
The USGS wants you to plot a second data set on a map to illustrate the relationship between tectonic plates and seismic activity. I need to pull in a second data set and visualize it along side your original set of data.
Found Data on tectonic plates at https://github.com/fraxen/tectonicplates.
Steps:
-
Plot a second data set on my map.
-
Added a number of base maps to choose from as well as separate out our two different data sets into overlays that can be turned on and off independently.
-
Added layer controls to my map for Overlays and choose buttons for Earthquakes and Tectonics plates locations.
Grayscale Overlay
Outdoors Overlay
CHALLENGE COMPLETE!!
Final product will be assessed on the following metrics:
-
Completion of assigned tasks
-
Visual appearance
-
Professionalism
