Issues we always face…
GPS Accuracy
How to connect field data attributes to the GPS dataPaper? Computer in the field?
Equipment – what do we buy?
Smartphones and Tablets are great – but how do you get the data off of them?
Geotagged photos are great – but where’s the tag?Where you’re standing? The object that is focused on?
Do we store photos on a server or with the actual data?
Need for WIFI or Cell serviceThis translates to $$
GPS Accuracy
The Game Changer
ESRI Collector App’s ability to go off-lineNo need for wifi or cell connection
Allowed us to use the cheaper Android tablets to allow students to collect field data
Including photos!
Allowed students to use their own devices to collect field data
Some hurdles…
Users must be part of and AGO organization
Users must also be part of a GROUP within the organization
Need for intimate understanding of ArcGIS Online
Users must know what Collector is capable of and how it is best used
Setting it up requires knowledge of geodatabasesDomains
Attachments
Must understand proper options when publishing data as a service for use in collector
In order to offline and have a basemap – you have to know WHERE TO FIND THE OFFLINE BASEMAPS
Some hurdles…
Users must be part of and AGO organization
Users must also be part of a GROUP within the organization
Need for intimate understanding of ArcGIS Online
All students had to be added to the University AGO organization
They were then added into a group for our class so they could view the class maps
Students were introduced to ArcGIS Online and its functionality through an exercise using premade data
Based off of the Fall 2012 ArcUser article “A Workflow for Creating and Sharing Maps” by Keith Mann
Some hurdles…
Users must know what Collector is capable of and how it is best used
Students had to download the app
Course instructor created testing data that students simply had to download through Collector to use
Some hurdles…
Setting it up requires knowledge of geodatabasesDomains
Attachments
Students had already learned about geodatabases, domains, and attachments through a week-long module and lab assignment
Some hurdles…
Must understand proper options when publishing data as a service for use in collector
Students were given detailed instructions on how to create their feature class data, publish their data and map
Some hurdles…
In order to offline and have a basemap – you have to know WHERE TO FIND THE OFFLINE BASEMAPS
Students were given instructions and the url link for the offline basemaps
But LOTS of successes!!!
Beyond the Classroom….
Lava flow core collection in Mexico
Parking spot inventory on campus
Shoreline trash data collection
Bike rack inventory on campus
Fourth grade science week activity
Lava Flow Core Collection
Project needed to give researchers access to a geoferenced map with historic lava flow data
Needed to include their location on the map
Needed to be on a device
Needed to be offline
Lava Flow Core Collection
PhD student digitized historic lava flows into geodatabase feature classes from georeferenced images
GDB was published as a service
Web map was created with sync capability for Collector
Lava Flow Core Collection
Lava Flow Core Collection
Lessons learned:Visiblity settings within ArcGIS online matter – A LOT!
Adding the offline basemap as a BASEMAP is important
Parking Spot Inventory on Campus
Client project for Advanced GIS students – Miami University Police Department and Parking Services were the clients
Clients needed a database of all parking spots on campus
Database needed to include XY location
Picture of any signage (with condition of signage)
Type of parking (red, yellow, handicap, etc)
Parking Spot Inventory on Campus
Students were tasked with testing various field data collection methods
Parking Spot Inventory on Campus
Lessons learned:Accuracy of different devices varies
Turning OFF WIFI helps with more accurate locations
Device GPS just isn’t accurate enough for this type of project
Ability to use Collector would have greatly increased the production efficiency for this project
Shoreline Trash Data Collection
Client project for Advanced GIS students
Client desired a digital method for collecting location of and type of trash along shorelines
Students created a Collector Application and dealt with privacy settings for individual collectors
Shoreline Trash Data Collection
Students had to develop a database schema for the collected data (based off of paper shoreline data collection sheets)
They then published and tested the app
Shoreline Trash Data Collection
Lessons Learned:Map must be downloaded the device prior to site visit
If GPS isn’t working well, can manually plot points
Data security can be managed
Students are REALLY creative
Bike Rack Inventory on Campus
Graduate Student initiated project for Office of Sustainability
Student had been in the Advanced GIS class and knew tablets and collector could help!
Bike Rack Inventory on Campus
Anna used Android tablets from the Dept of Geography
Collected location, condition, and image
Bike Rack Inventory on Campus
Lessons learned:The weather will affect your data collection
You can’t count on all devices working properly
The sharing options on both the data and the web map must be set properly for the end product to be seen by the intended audience
Elementary STEM Fun!
Talawanda Science Week – 4th grade activity
By now they have visited me to 1. Play with Google Earth
2. Use GPS units to collect waypoints
3. Learn about cardinal directions
I wanted to take advantage of mobile technology (tablets) that they all use at home to do “scientific” data collection
The result: What is this mysterious bird that we keep finding signs of in Cook Field?
Students were given tablets to go off and collect data
There were “feathers” and “eggs” to locate and tree ages to estimate
At the end they were asked about what inferences they could make about this mysterious bird
What did they infer?
Orange and Blue birds like to live near each other
Purple and Yellow birds like to live near each other
Green birds are loners
Green, blue, and purple birds tend to live in trees close to where they lay their eggs
Yellow and orange birds lay their eggs relatively far from their nests in trees
Blue and Orange birds tend to prefer younger trees to make their nests
Elementary STEM Fun!
Lessons learned:Kids love to play with technology – pass out the tablets AFTER you have explained what they will be using them for
Some tablets will cease to work – roll with it
Some kids will hate this activity – make them do it anyway
Some kids are awesome data collectors…others are not
• VS
YOU (the professional) will learn A TON by setting up & deploying this project
So what’s next?
The Trimble R1 GNSS ReceiverCan be used with Android and Apple phones and tablets
It should increase our positional accuracy so the Collector App can be used for detailed data collection in the field
