BikeOut is a tool to show you what’s accessible by lane/other facility cycling, vs regular direct routes. It shows how the current cycle infrastructure brings some places closer, or how there are islands of difficult-to-access places now made accessible by new links. 

Here’s a demo: 

Red shows the fastest route (within 1 mile for d/town Bk, 8 mins for Union Sq). Green shows the same time/distance for the safest routes..

Thump thump. There’s a lot of data out there. Right now, someone sent a geolocated tweet from over the road. Thump thump. And you’re sitting in a tax block that has three DOB violations, one outstanding road surface issue and an unresolved request for a bike rack. Thump thump. Someone upstairs in your building is photographing local stores and putting them on twitter, and just last week a volunteer group came by and uploaded details of your street trees to a webmap. Thump thump.

The Happening City map keeps an ear open for new data, all the time. As geographic information gets published, the Happening City absorbs it. Each update or new source is a mini heartbeat, and collectively the pulses of new information show what’s happening around you.

Zoom out, and the map really becomes informative. Each time new data is released, the map updates all five mile grid cells covered by that information. Compare places to get a sense of the scale of open data that we’re generating. If content generating, open places are liveable, find the hotspots on the map and move there. Keep zooming, and the grid resolution becomes coarser. You’re looking at the pulse of cities, regions, society, humanity.

Thousands of data layers go into the Happening City map, from federal datasets to local crowdsourced info. It’s a dynamic artwork, and an essential tool to measure the vibrancy of cities and regions. Wizzy algorithms plus some whizzier humans keep the inventory up to date and wise to the latest feeds and downloads. Everything gets republished as a data feed — we’re smart enough to avoid including that in the aggregation, could lead to a black hole.

Noteworthy turns your precious Moleskines, Muji notebooks and Staples pads into tagged, indexed graphics on your desktop, iPhone and iPad. Combine the beauty and flexibility of a paper notebook with a intuitive and powerful digital book editor.

Ever wished you could look something up in an old notebook? Are you carrying two full notebooks, just in case you need to refer back? How easily can you find those initial sketches from a couple of months ago? Have you ever backed up those notes?

How Noteworthy turns your old notebooks into essential reference materials:

1. Sign up on the Noteworthy website. Print off the mailing label, and drop your notebook into the mail. Buy a three notebook deal for the best rate. We’ll even send you a fresh notebook.
2. The Noteworthy team scan the notebook, and alert you by email. This process takes a few days, but it’s worth the wait.
3. Go online to browse the notebook pages in crisp high-resolution images. Tag any page section with keywords - maybe a project number, or client.
4. Download the Noteworthy app to your mobile device, and browse your notebooks anywhere. Search, tag, share, forward as pdf to email.

The notebook pages aren’t just images, they’re like a hypertext-enabled super version of your printed notebook. Noteworthy’s cursive script recognition identifies and tags of titles and dates. It detects and tags changes in pen or density of text, helping you divide the notebook into logical chunks. And images are extracted from pages, making it easy to find that critical chart or diagram.

Noteworthy isn’t the end for your filled-up notebooks. It’s the beginning. Keep annotating. Make links to other pages, add tags, link to external documents or embed the pages in other places.  Noteworthy remembers these layers of data and presents them on the page, alongside your original scribbles.

Meanwhile, carry on taking notes in your current notebook. It’ll become Noteworthy soon enough.

WhereItGoes.org shows your personal sewage and stormwater overflow infrastructure. In a heavy rainstorm, sewage and stormwater mix and discharge into local waterways at CSOs (Combined Sewage Overflows).

WhereItGoes.org estimates the flow of stormwater and sewage for any address you provide. Factoring in rainfall, elevation and information about city-wide infrastructure, interactive maps show you the most likely CSOs serving your block.

Change location on the map, and see the CSO mapping change. Click a CSO to read more about it, upload your photos and leave comments. Add a CSO to your watch list, and get alerts via email, SMS or social media when an overflow is imminent.

(For more on CSOs in NYC, check out Storm Water Infrastructure Matters.)

Community Supported Agriculture is sprouting up in many cities - over 100 groups are offering vegetable shares in NYC this year, up from 70 last year. Most are run on a volunteer basis.

CSAmazing is a hosted web management system for CSAs, taking care of the most common tasks, including payment, registration and volunteer coordination.With CSAmazing, volunteers spend less time working on admin, have an easier time delegating and can help the CSA group grow together as a community.

Common CSA tasks managed by CSAmazing include:

• easy sign-up for new members, including waiting lists once all slots are taken
• flexible payment options - thanks to generous support from non-profit food organizations in NYC, online payments via CSAmazing have no fees.
• cost calculators allow CSA organizers to forecast income and costs over the season, and share this info with the farmer
• email and social messaging tools to communicate with members and other CSA volunteers
• volunteer shift management - flexible re-scheduling, reminders and nagging emails make the process of staffing the CS pick-ups very smooth
• farmer communication, including details of vegetables each week
• tools to share data with other CSA organizers, to support local food efforts and build on experiences from other schemes
• a flexible, modular system, with optional extras including recipe databases, photo sharing and community food mapping

Getting a CSAmazing portal is simply a matter of registering with the main CSAmazing site, and filling out some info about the CSA. A custom domain is automatically set up, like this: crownheights.csamazing.org. With some simple customization though the admin interface, costs, shift times and other essential info can be entered.

Development of CSAmazing is open source, with a tiny team of developers supported by small contributions from participating CSAs and generous assistance from food-related foundations. Using a hosted solution means that backups, upgrades and security updates are taken care of. And since the underlying system beneath CSAmazing is a widely-used content management system and database, the foundations are solid.

The site is optimized to be undemanding. It runs smoothly on mobile devices and also older hardware and older browsers - helping CSAs reach a wide audience across the spectrum. The mobile version of the site even allows volunteer coordinators to check off shifts and edit schedules directly at the pick-up location.

Do you run a CSA? Say goodbye to miscellaneous google docs, long email chains and binders of volunteer shift coordination - sign up for CSAmazing today.

Introducing View Finder, a web tool for evaluating the visual impact of new transmission corridors.

Placing power transmission lines across the landscape is a necessary to transmit energy from source to destination. Until we get a breakthrough in efficiency, distributed and localized generation, new transmission corridors will be needed.

Choosing where to put corridors is contentious and drawn-out - for example, see the well-documented campaign against new corridors in Virginia run by the Piedmont Environmental Council. Reviews take a long time, and require data, expert analysis, public and stakeholder consultation. What if new tools could help make the processes more effective?

Here are two such tools:

• View Finder. A visibility analysis for the entire US, running in your browser. Discussed below.
• Path Finder. A collaborative platform for contributing, assessing and commenting on corridor options.

These two tools alone don’t resolve all the challenges around corridor placement, but they represent small building blocks towards more inclusive and open processes.

What is View Finder?

View Finder uses freely-available datasets to calculate what can be seen from a particular location. While detailed viewshed analysis is expensive and slow, View Finder provides a rough sketch of the same information in seconds, right in your web browser.

From your browser, click a point on a map, or draw a path to represent a transmission corridor (shown green in the screenshot below). View Finder overlays two colors: blue, showing locations that can’t see the point or corridor, and pink for locations that can.

Pre-set options relevant to transmission corridors allow you to specify the height of the pylons. Taller corridor infrastructure increases the size of the possible viewing area.

Vegetation cover data are used to calculate summer and winter views, where the corridor is located in or near a deciduous forest.

The ground cover also affects how likely you are to see the corridor from each location - forest gets in the way more than scrubland, for example.

After tweaking the settings, share, save or print the viewshed.

Behind the scenes, View Finder uses the National Elevation Dataset, and the National Land Cover Dataset. Both are stored in Amazon Elastic Block Storage, and called as needed by a GRASS GIS script running in Amazon Elastic Cloud Compute to calculate the visibility for the current location. Map tiles showing the view shed are generated on the fly by Mapnik and stored for re-use.

View Finder is an integral part of Path Finder - to be covered in a follow-up post.

Once the Open Neighborhoods Project is set up, the collaborative neighborhoods will form the basis for a fair re-districting of electoral boundaries. Rather than a few people determining how votes are accumulated, the same tools that support complex online collaboration for neighborhoods will be used to openly and fairly correct distortions in how we elect our reps.

Districts can be determined by a combination of commonly-held local boundaries, and geography. We have the tools: social media, versioning, open geographic standards, an engaged development crowd. Other nations have independent commissions to determine districts - but nothing open and crowd-sourced. There’s a lot of prior art in this area, most of it in the ‘dark arts’ category. Too bad.

This is the first Census year where a people’s redistricting is possible. Could be amazing. Let’s fix this embarrassment.

UPDATE: As well as prior art, there’s active art happening right now along the same lines at Redistricting the Nation. It’s hopefully obvious that none of the ideas on here are original research - just tossing out some sketch thoughts, rather than trying to give a state of the art with all due diligence. Turning on comments here soon so it’ll be easier to add other existing examples.

The Open Neighborhoods Project is an independent, crowd-sourced repository of neighborhood boundaries for the US. Three parts:

• a web map for anyone to contribute their neighborhood boundary
• tools to review and agglomerate different neighborhood outlines into commonly-accepted boundaries
• a data repository of current and previous neighborhood boundaries for download and re-use, forming a People’s Atlas of neighborhoods

Why

Only people who live in a neighborhood are able to define its geographic extent. But neighborhoods are the ideal data frame for many activities – local government, map making, planning initiatives, journalism, electoral districts, statistical comparisons, hyper-local news, agglomerations of geo-located data, etc. Most people seeking to describe a neighborhood are ill-informed to define its boundary. Centralized attempts to define neighborhoods will always fail.

A People’s Atlas of neighborhoods is possible, now: the web-based mapping tools are ready. The open process precedents for reviewing neighborhoods are ready. The data exchange standards are ready.

The published neighborhoods will form a foundation for relevant local action. Imagine mapping city-wide data using districts that were relevant to their residents. Imagine making statistical comparisons between areas that respected local definitions of place. Imagine re-drawing electoral districts from a base of non-partial local boundaries. Imagine your hyper-local news actually reflecting the place you live in. Imagine historians reviewing the changes in neighborhoods over time.

#1 The mapper

The Open Neighborhoods Project website is built around an open source, standards compliant web map. Any visitor to the website can register, adjust the map to show their area, and draw a boundary. This boundary can be named, and saved.

Optionally, the boundary can be constrained to snap to existing local boundaries, such as Census Blocks, county line, etc.

#2 Tools for analysis and review

Learning from open source software projects, the process for storing, reviewing and analyzing the neighborhood data is completely transparent. Individual boundaries can be recalled, or all boundaries overlapping a particular area. Comments can be attached to particular boundaries, and reviewed when inspecting a map.

A toolkit allows visitors to review all boundaries for a particular neighborhood, and select from present interpretations that dynamically processes the lines into a common boundary. Different methods of interpretation give different results.

Decisions about which interpretation to use as the “published” boundaries are made through open discussions via mailing lists, with guidance from an advisory committee of cartographers and demographic data experts.

#3 Data streams

The neighborhood boundaries are offered as dynamic feeds in all modern formats.

Users can download the neighborhoods into any map tool, including Google Earth, and other GIS platforms.

Feeds allow direct integration into other software tools. News sites can adjust their news coverage as borders are changed. Analysis built with census data on the neighborhoods will update to reflect the changed consensus of a boundary location.

Historic review allows anyone to inspect a boundary at any point in time.
