Who: Code for BTV & Vermont Center for Geographic Information
What: Free Geographic Tech Talk for Burlington's General Public
When: Friday, September 29, 6pm (5 PM at ArtsRiot for Geobeers, followed by...Tech Talk at BHW)
Where: At Big Heavy World, inside the SEABA Center at 404 Pine Street, Burlington (Map: https://goo.gl/maps/qksaxeaB7tA2 )
This event is an opportunity to get together with Geogeeks AND the public to share how cool geospatial technology really is. Meetup at ArtsRiot next door at 5 PM and then we will head over to the GeoTech Talk at Big Heavy World (how appropriate!). Bring your friends who don't understand what you do!
Drones, helicopters, and planes are shooting lasers at the earth. Why? Satellites are staring down at us from space all day, and all night. What do they see, and how is it being used? Friends and neighbors are working for the city using their phones and tablets with GPS devices to collect all sorts of details about the city around you. What does the city use it for? Does it affect your taxes or how long a fire truck takes to reach your house? Are your photo posts on Yelp, Facebook, Twitter, or Instagram helping your community, or just changing the ads you see in your web browsing? If we take the lasers, the satellites, and the phone GPS data, and mash it together onto a map, what things can we see and do?
Are you just plain curious about place-based information (i.e., geo-spatial data)?
Please join Code for BTV, and the Vermont Center for Geographic Information, at 6pm on September 29th, for this free public discussion on what geographic data systems are, how they are used around you every day, and why it might matter to you. The event is being held at Code for BTV’s home base, Big Heavy World inside the SEABA Center at 404 Pine Street in Burlington. RSVP for the event at https://www.meetup.com/CodeForBTV/ The venue is handicapped accessible.
This will be both a presentation, and a free form discussion on the topic of geographic data and the systems involved in collecting, managing, and using it. It’s all geared toward the general public that knows absolutely nothing about geographic data. The presentations will teach from a high level general perspective how these systems work, and then show you the myriad of ways that they are used to help you, record you, influence you, and provide you with world understanding that would be otherwise unattainable. The presentations will be fun, lightweight, and visually exciting.

Description of Problem
- VT Open Geodata Portal (Portal): Use this procedure if you downloaded the imagery via the Portal. NOTE: By default, the Portal’s “Tiled Data Download Tool” will only give users the *.jp2 file, meaning you won’t have any *.aux or *.aux.xml files to worry about. However, if you bypassed this interactive selection tool and “bulk downloaded” directly from the web folder then you’ll need to follow these procedures (assumes Windows OS).
Browse to the folder where you downloaded the files.
Sort on the “type” column.
Carefully Select and Delete all *.aux and *.jp2.aux.xml
Repeat for all 2016 orthoimagery datasets (e.g. 30cm, 15cm, black & white, color).
- Offline Data Product: If you ordered an offline product containing the 2016 imagery
Browse to .\VIL\IMAGERY\VTORTHO\0_3M\CLRIR\2016\COMP
Sort on the “type” column.
Carefully Select and Delete all *.aux and *.jp2.aux.xml
Repeat for these folders.\VIL\IMAGERY\VTORTHO\0_3M\PAN\2016\COMP.\VIL\IMAGERY\VTORTHO\0_15M\CLRIR\2016\COMP.\VIL\IMAGERY\VTORTHO\0_15M\PAN\2016\COMP

VCGI periodically assesses its suite of Web Map Services to determine if modifications are needed. We analyze usage statistics to identify "low-use" and "high-use" services, and then target adjustments accordingly. These adjustments include a range of things such as configuration changes to improve service performance OR adjustments to low-use services to reduce their standing load on the server. In some cases we may choose to retire services.
So what is changing? Based on our most recent assessment (7/21/2017) VCGI will be making the following changes to our suite of Web Map Services. The services designated for "retirement" will be supported for the next 90 days (retired on 10/31/2017). Services designated for "replacement" will also be supported for the next 90 days, but user should begin migrating their applications over to the replacement services as-soon-as-possible. All services noted in this notice are available via this REST endpoint (http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services).
Some Low-Use Services to be Retired on 10/31/2017
EGC_services/MAP_VCGI_ALLIMAGERY_SP_NOCACHE_v3 (are being replaced by new services noted below)
EGC_services/MAP_VCGI_ALLIMAGERY_WM_NOCACHE_v3 (are being replaced by new services noted below)
Some High-Use Services to be Replaced on 10/31/2017 (replacement services are already available for porting)
EGC_services/MAP_VCGI_ALLIMAGERY_SP_NOCACHE_v3 will be retired and replaced by the following (note: the original service layer IDs have been kept the same)
EGC_services/MAP_VCGI_ALLIMAGERY_WM_NOCACHE_v3 will be retired and replaced by the following (note: the original service layer IDs have been kept the same)

VCGI has begun to explore the possibilities of Power BI, Microsoft's "business intelligence" data modeling and visualization tool.
In this simple example, VCGI downloaded the location of Vermont owned or leased buildings from the VT Open Geodata Portal. The option to download in "spreadsheet" format was chosen, which provided a CSV file. The CSV file was pulled into Power BI Desktop and used to create the donut chart and map shown below.
The chart depicts the number of buildings owned and/or leased by specific State of Vermont agencies or departments. Clicking on one of the sections on the donut chart will "filter" the map to the towns where particular agencies/departments have buildings.
We are just getting our feet wet. We anticpate doing more as we explore the potential of business intelligence tools to enhance data visualization, data exploration, and data-driven decision making.
