GPS Navigation Survey
TeleNav is holding a survey to find out what users think the good, bad, and potential are of GPS navigation apps. The survey is only page with questions asking users which GPS navigation apps they use and what they like about it. Telenav is also looking to understand what future capabilities users are looking for in their GPS navigation apps. Those that submit completed surveys are eligible to win one of five $50 Visa gift cards. In addition, Telenav is looking to bring together a small focus group in the San Francisco and Seattle areas to brainstorm. Take the survey: Smartphone Navigation App Questionnaire. The survey period ends at midnight on October 19, 2012.
UC Berekely faculty member Darin Jensen is heading an effort he refers to as Guerilla Cartography. Food: An Atlas, is a Kickstarter funding project described by Jensens as "a cooperatively-created, crowd-sourced and crowd-funded project of guerrilla cartography and publishing." Over the past five months, Jensen and his team have collected over sixty maps focsuing on food production, food distribution,food security and cuisine. Examples of maps curated for this atlas are the changes in the agrarian landscape in Los Angeles, worldwide croplands, and taco trucks in East Oakland. There is also a special children's section created by UK’s Geography Collective. A call for maps was sent out in June of 2012 and since then food related maps and inforgraphics have been submitted.
The project is described as a no-profit effort, meaning that all the work has been donated and any proceeds from the sale of the atlas will be donated to a food related organization. The Kickstarter project is seeking to raise $20,000 in order to print 1,000 atlases and 100 special editions for sale. The goal date for sending the completed atlas to the publisher is November 15, 2012.
A peek at some of the map selections for Food: An Atlas: Historic Agrarian Landscape, Backyard Farm Project, Almond Trade, Farmers' Markets Accessibility, Food Resiliency.
Calculating Population Density
The U.S. Census tackles changes in population density in urban areas between 2000 and 2010 in its report "Patterns of Metropolitan and Micropolitan Population Change: 20oo to 2010". Simply diving the total population by the total area is can be a misleading method of quantifying the population density of cities in the United States. The spread of population across an urban area is rarely homogenous. Richard Florida of Atlantic takes a look at the population density calculation methodologies the U.S. Census used to analyze what he refers to as concentrated density which uses population-weighted density.
Google Introduces Map Tracks and Geolocation APIs
Google has introduced two new map APIs for developers: Map Tracks and Geolocation. Both APIs are aimed at businesses that have in-motion resources they need to track such as a fleet of vehicles or employees who travel. From Google's post:
- Google Maps Tracks API allows an organization to build applications that can store, display and analyze GPS data on a map. The API is built on top of Google’s reliable cloud infrastructure and offers specialized features such as geo-fencing.
- Google Maps Geolocation API enables an application or device to determine its own location without the use of GPS by looking up the locations of nearby wifi access points and cell towers. By limiting GPS usage, a device can save battery life and work indoors or in remote areas.
The Map Tracks API incorporates geofencing
which companies can use to receive notifications when certain geographic boundaries are cross, for example when a delivery truck goes outside of its predetermined service area. Both APIs are available for purchase from Google.
Esri Acquires Geoloqi
Location-based technology startup Geoloqi has been acquired by Esri. Amber Case, the CEO of Geoloqi, will become the director of Esri's R&D Center will which take over Geoloqi's headquarters in Portland, Oregon. Geoloqi which was founded in 2010 and started with $350,000 in seed money and is a platform that provides location-based capabilities for developers to add to their apps. VentureBeat has a nice human-side perspective on why Amber Case chose to sell to Esri.
A GIS based geo-social network is getting set to launch in beta called Footpixel: We are creating a geo-social network that will give you access to anything you want to know about any location, live as it happens. When Footpixel is launched, no corner of the world will be left untouched. Enter your email to receive an invite when it launches.
