From the ground to the cloud: forest monitoring in Hutan Aceh

April 7th, 2015 by Yaw Anokwa

Hutan Aceh is the endangered home of tigers, elephants, orangutans and rhinos. EIA International and local activists from Koalisi Peduli Hutan Aceh (KPHA) protect this home by documenting forest crimes with Open Data Kit. The geo-tagged forms, rich with photos, provide the evidence needed to save habitat.

EIA has a great post on the Hutan Aceh project, and the video below does a great job explaining the project. Visit hutan-aceh.com to view images from the ground.

Finding and fixing vacant properties through crowdsourced data collection

March 26th, 2015 by Waylon Brunette

Shantanu Singh is the founder of Vacant Voices, an organization committed to solving the problem of abandoned homes in America's neighborhoods. In this guest post on Nafundi's blog, Shantanu explains how Vacant Voices uses ODK to collect and deliver crowd-sourced neighborhood data to community organizations who can make a difference. The full blog post is available here.

An excerpt of Shantanu blog post:

Vacant properties are an important issue that needs an urgent solution. A 2015 report concluded that 1 out of 4 foreclosures in the United States are vacant. The actual number at the end of January 2015 was over 142,000. The number is alarming when you consider the contagion and deleterious impact caused by vacant homes. Research has established that these blight-causing properties reduce property values, increase crime rates, and worsen physical and emotional health.

At Vacant Voices, we wanted to develop a tool to help these communities. One that would allow residents to collect data (e.g., a GPS tag for the location, a standardized description, and an optional image) of problem properties. The collection could be spontaneous or scheduled. Community-sourced data that we could deliver to decision makers was our goal.

Through prior experience, we understood municipal categorization of vacant properties to be technical and not uniform across the country – in short, not user friendly. At the same time, we knew geographic information systems (GIS) and government data already existed (the statistics above were extrapolated from federal and local data). However, these systems can be hard for communities to find, can be complicated to use, and use old data that may not even be relevant for the specific need.

To collect and analyze data sourced from the community, we needed a better way. After a lot of research, we came across ODK. It seemed too good to be true. In front of us, there was a solution, one that not only provided a checklist interface, it also organized the data into a database (no data entry!), and you could visualize the spatial relationship of properties on a map, along with performing analytics useful to decision makers. Now we could standardize the definition of a vacant home, in a rubric that eliminated subjectivity.

URGENT ACTION REQUIRED by April 19th

March 31st, 2015 by Mitchell Sundt

"Sign in with Google" for ODK Aggregate will cease to function beginning April 20th.

ACTIONS REQUIRED:


ODK Aggregate 1.4.5: provide all users that have been accessing the webserver via "Sign in with Google" (e.g., Gmail account) with an ODK Aggregate username and password (you must specify an initial password) to use instead of their Google credentials after April 19th.

Be sure to Save Changes to apply these changes!


ODK Aggregate 1.4.4 and earlier: create an ODK Aggregate username and grant it Site Admin permissions and an initial password. Use this username instead of the Google account specified in the installer when administering the system after April 19th.

As described in the 1.4.5 action section, above, define ODK Aggregate usernames and passwords for all users of your website.

Be sure to Save Changes to apply these changes!

Consider upgrading to 1.4.5 to prevent the accidental deletion of this "super-user" username (and the resulting inaccessibility of your server) ( see AggregateReleaseNotes for upgrade steps).
