A brief history of the digital map

Nice consise history of mapping from his lecture "The Ubiquitous Digital Map" by Gary Gale, Director of Global Ccommunity Programs, HERE.

1906 Earthquake & Present Day Photo Mashup

Shawn Clover recently released part 2 of his “1906 + Today: The Earthquake Blend” series which is a mashup of 1906 earthquake aftermath photos in San Francisco with present day photos at the same location. The photos are blended creating a seamless image of the past superimposed on the present.

View part 1 of the series here from 2010 and part 2 of the series here from 2012.

Tim De Chant explains why you should be excited about vector-based maps in iOS 6

Former kellylabber Tim De Chant has a nice piece on the upcoming apple mapping software for mobile devices:

Apple announced today that it’s revamping the Maps application on iOS devices—iPhone, iPad, iPod touch—introducing a lot of showy new features like turn-by-turn directions and 3D flyovers. While those make for sexy commercials, they won’t be as impactful as the switch from raster- to vector-based map data. If you’re not sure why you should be excited about the change—and you should be—read on.

Check out his blog post here.

Jonathan Crowe (formerly of The Map Room, now of "My Correct Views on Everything") has a comprehensive post on the subject here.

Apple mobile mapping software? coming soon!

We mac users are all a-twitter about the news of an impending Apple mapping software. Here is a sample from NPR:

There's been speculation for months that Apple will try to elbow Google's popular Maps app aside on the iPhone and unveil its own map app, and some of the best evidence yet comes from Tuesday's Wall Street Journal.  The paper looked into the reasons for the impending switch and the broader implications it would have for the smartphone market.  The article continues...

The new software is rumored to be leaner, meaner, and packing a rad 3D visualization capability. It will be unveiled as soon as next week at the annual Apple developer conference in San Francisco.

The structure of a city via Twitter

From Mashable Tech.

Check out this gorgeous visualization of NY City's tweetopolis from Oakland-based programmer Eric Fischer.

He plots out the motion of New Yorkers using public tweets on Twitter with geotags from May 2011 until January.

The project lays out around 10,000 geotagged tweets and 30,000 point-to-point trips in cities like New York City to plot the flow of people in terms of favored paths. In his map of NYC, seen above, there is a huge ink blot lining Broadway; as we’ve long suspected, it looks like the busy avenue is the backbone of the city.

Using a base map from OpenStreetMap, he drew out transit paths using Tweets. Movements are indicated on the geolocation of a Tweet, with an individual’s start point marked with one geotagged Tweet and ending with the next geotagged Tweet. This is what creates a mass of traffic routes.

Similar viz of the east bay“If you just draw lines from the beginning to the ending of each trip, you get a big mess, so the challenge is to come up with more plausible routes in between,” Fischer told Mashable. “That is where the 10,000 individual geotags come in, the most plausible routes are ones that pass closely through places that other people have been known to go.”

Fischer used Dijkstra’s Algorithm to calculate what exactly to map out. For those of who haven’t thought about math since high school algebra, that’s an equation that maps out the shortest path between two points on a graph. For this project, the equation pointed to the relevant paths to map out a city’s most dense corridors.

This might be of use for our mobility project with our space.

Wall-E was right, in 3D this time

As a follow-up to the post from last year from NASA showing a nice 2D visualization of the earth's satellites, here posted is a new 3D video visualization of their locations viewed in Google Earth. Why do we never see these critters in our imagery? By Analytic graphics inc. and gearthblog.com

Transit & Trails: Go hiking without a car in the Bay Area

Ryan Branciforte at the Bay Area Open Space Council reports on their new web tool: Transit and Trails. The new interactive website identifies more than 500 trailheads and 150 campgrounds in our region’s 1.2 million acres of preserved lands. Just enter your starting location at Transit and Trails’ Google Maps-powered site, and select the radius. Once you’ve picked your ideal trail from the results, Transit and Trails will open a new link in 511 Transit Trip Planner, where you’ll find a detailed trip itinerary, complete with a map, transit times, fares, and walking directions to and from the transit stop. Very cool.

Some favorite ecology-related mashups

From Ken-ichi Ueda and friends: iNaturalist.org.

• Where you can record what you see in nature, meet other nature lovers, and learn about the natural world. Colorful, well-designed and useful, this site is a must for all you explorers of the natural world, or those of you who just ponder the wildlife in your backyard.

From GreenInfo Network and CalLands:

• The new California Protected Areas Database (CPAD 1.3) has just been released in geodatabase and shape file formats, and is available through google maps overlay here.

From UC Davis' Road Ecology Center and the Information Center for the Environment: California Roadkill Observation System.

• You can report roadkills you observe anywhere in the state, helping all of us to understand the causes of roadkill and how we can reduce the conflict between animals and vehicles. Roadkill is a major cause of mortality for many animals in California, but designing appropriate management responses takes political support, money, and knowledge of where and how to act. Roadkill data are an important part of that equation and we invite you, our expert colleagues, to join us in collecting these data on a public site.

From my lab: the OakMapper.

• OakMapper is designed to let users explore the locations of confirmed P. ramorum sites, and contribute to our database by reporting trees that might have the disease. And it is now mobile! Speaking of mobile:

From Imperial College London: EpiCollect.

• A mobile phone application will help professional and "citizen" scientists collect and analyse data from "in the field", anywhere in the world. The EpiCollect software collates data from certain mobiles - on topics such as disease spread or the occurrence of rare species - in a web-based database. Uses Android. The BBC article.

OakMapper has gone mobile!

Not be mistaken with OatsMapper.com (mapping Hall and Oats reunion concerts), the OakMapper has gone mobile!

If you have an iPhone with OS 3.0, you can now download and install the mobile version of OakMapper on iTune's App Store for free. The mobile version of OakMapper allows you to do the same thing as the web version: view submitted Sudden Oak Death cases and report a SOD occurrence. However, the OakMapper makes those two actions much easier by taking advantage of the GPS unit onboard the iPhone. The GPS coordinates provided by the iPhone will allow you to quickly report an SOD case and will allow you to find out all the submitted SODs within a 20 miles radius around you. We hope that the ease of reporting SOD cases using the OakMapper iPhone application will encourage more submissions from the general public who own an iPhone. 

New Interface for the Manhatta Project. Check it.

We talked about this before here; and the Manhatta project has a nice new interface for exploring the 1609 map of the island of Manhatta(n), block by block, through time.  I love this project! The combination of mashup, history, design and art are breathtaking.  (And our own Tim Bean worked on reconstructing the early topography! - see his comment below.) Go Fullscreen on your 30"-monitor. I dare you.

“The goal of the Mannahatta Project has never been to return Manhattan to its primeval state. The goal of the project is discover something new about a place we all know so well, whether we live in New York or see it on television, and, through that discovery, to alter our way of life. New York does not lack for dystopian visions of the future…. But what is the vision of the future that works? Might it lie in Mannahatta, the green heart of New York, and with a new start to history, a few hours before Hudson arrived that sunny afternoon four hundred years ago?”
