San Francisco Construction Projects

Project Objective

The goal of the Envista Mapping App is to map the City of San Francisco's Envista construction projects using data from the City's Open Data portal.

How to Interact with This Map

This map uses a clustering algorithm which shows a single symbol (an orange, yellow or green circle) to represent multiple data points (a.k.a. markers). The number inside the circle tells how many data points/markers the circle represents. If you zoom in or click on one of the circles, the map will expand to show more circles and markers.

To access information on a single construction project, click on the colored marker for that project and a popup will display showing pertinent details.

The marker colors denote the project's status:

• Red = Started
• Dark Blue = Committed
• Purple = Planned
• Cyan = Completed

Future Improvements

• Since the map takes a few seconds to load, add a spinning animation during this loading period.
• Consider using a base map that is visually simpler; perhaps a dark map (like Mapbox's dark base map) or a light, grey-scale map (OpenStreetMap Black and White, CartoDB, etc.)
• Possibly add a data viewing panel on the right side of the map similar to how the LA Street Wize site displays data as opposed to the current popups when a user clicks on a point in the map.
• Improve overall site layout, possibly adopt a similar layout to the LA Street Wise site.
• Provide more ways to look at the data by allowing users to:
  • query on a given time period and/or make it clearer which projects have started (red markers), which are upcoming (blue and purple markers) and which have been completed (cyan markers)
  • see the data by project class (gas, sewer, water, electric, transit, pedestrian safety, storm drain, etc. )
  • see the data by project owner (PG&E, SF Public Utilities Commission, SF Municipal Transportation Agency, AT&T, etc.)
  • query by address
