For the last couple of years, the Evangelical Lutheran Church in America (ELCA) has been planning to bring 30,000 youth from all over the country to Detroit for three days of service projects. (You may have heard about the "Skittle Factory Explosion.") The ELCA reached out to community organizations throughout Detroit to set up the projects.
In anticipation of the gathering, Focus: HOPE created the event's most ambitious project, ultimately employing 10,000 volunteers each day in an array of cleanup, board-up, mowing, and gardening projects in their 100 block revitalization area.
Check out this video to learn how project director Jerrell Harris worked with colleagues and community members to use Loveland's survey app and data from the Motor City Mapping project (the citywide survey built on Loveland's Site Control technology) in creating maps, workplans, and strategies to effectively deploy resources.
And... if you'd like to try out the technology yourself, head over to SITE CONTROL and take a look! We've got a great little video there to walk you through how you can make your own maps using Site Control.

A Farewell to Street View
At LOVELAND Technologies we love Google Street View. Really, so much, it's all love.
More than just an unprecedented way to drop in on almost any street corner in the country to see what's happening (as if that wasn't enough), Street View is a massive, and largely untapped, collection of street-level property data.
I use Street View extensively on my Tumblr, GooBing Detroit, to document the decline of Detroit property since the financial crisis. Street View's Time Machine feature, which allows you to go back and see Street View imagery for every year Google has driven a city offers an incredible near-past archeology of cities around the country.
Post-financial crisis, property decline in Detroit, captured by Google Street View Time Machine
So we are sad to say that when you click on a parcel in LOVELAND, you will no longer see an image of the property as captured by Google Street View. But do not fear -- we would never leave you imageless. As of today, when you click a parcel on LOVELAND, you will see the property as captured by Microsoft Bing's Bird's Eye oblique aerial imagery, along with the ability to rotate around the property:
But, before I get into that, some background on the departure from Google.
LOVELAND's base map comes from Open Street Map, and our map tiles are hosted on MapBox. We've spent years developing the system that supports LOVELAND's national parcel mapping, and the prospect of migrating to Google so we could continue using Street View was simply not feasible.
So we spent most of the last month trying to reach the right person at Google to whom we could explain our situation. We felt that our mission to put every parcel of property in the country online, each augmented by a Street View image, the data and imagery available for free, was worth the exception that the word "generally" in section 10.1.1(g) seemed to imply existed. We were more than willing to pay the Maps API for Work subscription price to include imagery in our paid service, Site Control.
Despite the valiant efforts of a number of current and former Google employees, we never seemed to reach the right person. It's understandable -- Google has 50,000 employees, and we're a tiny mapping company in Detroit -- I'm sure they have more pressing matters to address. Still, it would have been nice to have the chance to make the case for Street View in LOVELAND on the merits of our work and mission.
However, LOVELAND continues to use Street View in our Great American Parcel Survey project -- an effort to survey every property in the country using Street View imagery. We think this use of Street View is ok because the Survey app is entirely Google Maps based. Hopefully as the project grows we'll have something that shows Google our ability to use and explore Street View in new and unprecedented ways. Note that when you click a parcel in LOVELAND, you can click "Survey this Property" to open the property in the Great American Parcel Survey, see the Street View imagery, and survey the property:
A Bird's Eye Solution
In some ways Bird's Eye offers benefits over Street View:
Greater Parcel Image Accuracy
The Street View API often returns an image that is a parcel or two off from the one you've clicked on LOVELAND (an issue we seek to rectify through the Great American Parcel Survey, which actually lets you refine Google's API endpoint for a given parcel). With Bird's Eye imagery, we can outline the parcel you've clicked in the aerial image, so you know you're looking at the right place.
Ability to Rotate Around Property
When you hover over an aerial image on LOVELAND, you'll see rotate icons appear on the screen. Click those to see the property from each of the four angles Bird's Eye captures imagery.
The Future of Street View and Loveland
We're happy with Bing's Bird's Eye imagery, and for the channel it opens with Microsoft. We think Bird's Eye offers interesting new angles and insights on properties in LOVELAND, and we're glad that, should the opportunity open up to do more with Street View in the future, we know how to navigate both imagery sources, all towards the end of continuing to provide the public the best system in existence for understanding the parcel fabric that makes up our country.
We hope you enjoy exploring LOVELAND obliquely :-)

In June of 2010, the town of Millbury, Ohio was hit by an EF-4 tornado that killed seven and left over 50 buildings destroyed. As one of thousands of volunteers who helped with the cleanup, I saw firsthand the incredible damage caused by the tornado, and also the incredible efforts of first responders to bring order to a chaotic situation. Police, Fire, and EMS worked long days and nights to identify homes, help the residents, and coordinate cleanup efforts. The experience left a very deep impression on me.
Lake High School, destroyed in the Millbury 2010 tornado
One of the guiding principles at Loveland has been how we can take parcel data and use it to improve accessibility to data. After the April 2015 earthquake in Nepal, we started to look into how parcel data and surveying could be used in disaster relief situations. First responders often lack basic information about structures damaged by storms or earthquakes, making it difficult to accurately assess damage. How could our survey technology and methodology be used to improve disaster response?
On June 22nd, 2015, a large complex of thunderstorms moved across the midwestern United States, spawning 27 tornadoes, six of which touched down in Michigan. At about 2:30PM, an EF-1 tornado touched down about 3 miles west / northwest of Portland, MI, a small city of around 3,800 people, and cut across the city, severely damaging homes, businesses, and churches.
Drone footage of the tornado damage
The first images from the city were stark and haunting: roofs ripped off of churches, collapsed houses, huge trees snapped in half or uprooted. Fortunately, only two people were injured, and there were no fatalities. The National Weather Service estimated wind speeds of up to 100 MPH.
As with the Millbury tornado five years prior, our first instinct was to help. To that end, we began planning a survey of the tornado damage in Portland, with the goal of making this information available at no cost to first responders, academics, and the general public.
The first step was determining the scope of the damage and what parts of the city would need to be surveyed. As the parcel-hunting team worked to secure the parcel map of Portland, we considered our survey options. Ultimately we decided against going immediately to Portland unless we could get authorization from a local agency, otherwise we might end up obstructing recovery efforts. Four days after the tornado, we drove to Portland to conduct a preliminary survey to establish the rough geographic boundaries of the damage and what types of damage we would need to survey.
Using the information collected, we were able to draw an outline of where the tornado damage was located. Out of the 1,574 parcels in the city, about 500 were located in the path of the tornado. These would be the properties to survey. The parcel team contacted Ionia County and got the parcel shape file for Portland. With this uploaded to Site Control, we could now set up a survey area and questions.
The survey area.
For the purposes of this survey we used the standard question set with a few additional questions to quantify specific types of damage - whether a structure had been damaged, how badly, condition of the roof and windows, and if trees had been damaged.
Nine days after the tornado, we sent a crew of eight surveyors out to survey over 500 parcels in and around the path of damage left by the tornado. Teams of two surveyors fanned out across the city and surveyed all of the properties within a specific zone, taking pictures of each property, talking to residents, and looking for visible damage. This information was logged with wireless tablets using the Loveland app. It took about six hours to survey 500 parcels.
What the surveyors found was damage ranging from broken tree branches to structures that had totally collapsed. Of the 505 properties surveyed, 225 properties had tornado damage of some sort.
156 out of 207 structures had suffered some structural damage.

The severity of damage was concentrated along a thin corridor through the damage path. Buildings just outside the this path suffered minor or no damage.
The level of tree damage was fairly consistent with structure damage severity. Properties that had uprooted trees suffered the worst structural damage, although some properties on the periphery with especially tall trees escaped major damage.
Portland has a lot of old growth trees, many of which were snapped at the trunk or completely uprooted.

What we learned
Based on survey results, we found 156 structures damaged in and around the path of the tornado. Damage followed a fairly concentrated path, through which trees were uprooted and houses sustained severe damage. In other areas though the tornado seemed to have “skipped” over houses or streets, leaving them relatively undamaged - most notably on the west bank of the Grand River.
There were limitations to the survey that make qualifying the accuracy of the data collected difficult. Not all structure damage was visible from the outside, as we found with some properties where the owners were able to give us more detailed accounts.
The amount of time between the tornado and the survey - nine days - meant that much of the damage, especially tree damage, was already cleaned up by the time that surveyors got there. A more accurate picture of the damage would have been gained had we surveyed just a few days after the tornado, however, our presiding concern was that we not interfere with recovery efforts and give the residents of Portland some time to decompress.
The experience we gained through this survey led to us making some changes to how we approach natural disasters and the questions we ask. Specific questions about roofing and tree condition can provide useful information about wind speed. Future surveys will use more detailed questions, and also work with local residents to survey and upload real time information via the Loveland mobile map.

Knight Lab's Toolkit
One of my favorite toolkits of late comes from Northwestern University's Knight Lab. I made use of their image comparison tool, Juxtapose, in an earlier post looking at change over time in a Detroit neighborhood.
This time around I wanted to try out StoryMap -- the Knight Lab's fabulous contribution to displaying a series of events on a map supported by video, photography, social media, and text. For a subject matter to explore, I thought I'd take a look at a week's worth of structure damaging fires in Detroit.
Surveyors working on Motor City Mapping keep close tabs on every structure damaging fire in Detroit -- each is surveyed usually within a day of the fire. The city is especially vulnerable to structure damaging fires -- arson in Detroit is a well known and persistent problem.
Telling this story is challenging. Conveying the scale of damage across the size of the city, the challenges faced by the Detroit Fire Department... Detroit's Motor City Muckraker has taken on the task of documenting each of the city's fires, and while StoryMap wouldn't be ideal for presenting thousands of fires, it is perfect for presenting a slice of time that is indicative of the whole. In the map above you'll see 53 structure fires over seven days in Detroit. Typically Detroit averages 14 fires / day, the week above is around 8 / day.
As I started building my StoryMap I realized I was following a very repetitive process -- saving the image, titling the photo with the address, copy & pasting the notes. My colleague, Mike Evans, saw what I was doing and said, "Hey stop that, I bet we can publish automatically from Site Control."
Site Control is LOVELAND's (coming soon) software that gives you access to all the parcels and data that we present publicly, but in your own private LOVELAND universe. You can develop your own survey questions, pipe in data from open data portals, build and color code parcel maps, and build queries of the information in your maps.
Once you've done all that in Site Control, we want to give you options if you want to share and publish your maps. Of course Site Control maps are embeddable, or shareable in read-only formats, but now, you can also publish a Site Control map to StoryMap. That's what you see above. Thanks to some deft and thoughtful work by Mike, you can select data and photography in Site Control that you want published, and your StoryMap will generate with the selected content.
Even better, if you publish a StoryMap via Site Control and then continue surveying property in the Site Control map you've connected to your StoryMap, the new imagery and information will pipe into your StoryMap automagically.
We're still working on some things -- like making sure the progression through the story map matches the chronology of data in your Site Control map -- but this little proof of concept was too interesting not to share. More to come!
