suitable locations for new gas stations in mankato,...
TRANSCRIPT
Data
Collected data from MNDOT(Traffic data), TIGER(Road network), MNGEO (Elevation data), MN Geospatial Commons (Land Use data)
Aerial analysis to find the current gas stations in Mankato, used google docs to geo code the addresses into a layer.
Clipped all data to only include the urban area around Mankato.
Methodology
Reclassify data to favor ideal conditions for a new gas station. Use reclassified data to find optimal locations for Gas stations based
on proximity to major roads and distance from competition.
Use weighted overlay to assign different values to different conditions.
Find the best spots to build
Traffic Data
This was actually done outside the model then I ran a Euclidean distance on just the busiest 1/3 of ofstreets
Heavy Truck TrafficDid the same thing with the trucks and only took the top 1/3rd again to be used for the Euclidean distance
Land use Data
You cant just build a gas station anywhere you want.I cut out the landuses that were restricted to new buildings, like open water and already built-up areas.
FindingsUsing the Con tool I extracted only the two highest classes of suitability (left) and the highest bracket (right)
Findings
After using the Con tool to pull out only the highest ranked areas I converted them into vector data for better visualization and analysis.
Findings
Using only the highest ranked bracket I narrowed it down further by looking at the base map and hand deleting areas that are not suitable due to old data.
Findings
Remember this map from earlier? All 4 of the most ideal locations are further than three quarters of a mile from any competition, on stable ground (no slope), close to main roads, and sitting on Land that is buildable.

Past Inspections
Paper Inspection Forms – 10 forms. Storage – File and/or Scanned
Not easily mapped.
Difficult to search or query
Stormwater Inspection Goals
Provide a Mobile Solution for Stormwater Inspections Needs:
To be Accessible in various platforms.
Easily symbolized and mapped.
Ability to query data.
Provide Reports.
Collector for ArcGIS
Sufficient Option
Edit our Feature Services (related tables)
The inspection tables can be mapped easily through spatial views.
Easily searchable.
Collector for ArcGIS
Downside of Collector App: Collector Table window small &
Inspection Tables are Lengthy. The combination can make entering information difficult.
Needs a Customized Report Option. Python Reportlab.
ArcGIS Pro Map Seires.
Survey123 for ArcGIS
Survey123 is Multiple Platform Support.
User friendly. The forms are large viewable forms on tablets, phones, and pc’s.
Customizable Smart Forms. Pre-populate forms. Hide fields if they are irrelevant. Pass data to the survey form.
Inspections can be Easily mapped in filters or spatial views. Searchable
Built-in reports that can be customized.
Survey123 for ArcGIS
Hosted Feature Layer in ArcGIS Online We have multiple Surveys Forms 10 Stormwater
Point for each survey record. Stacked Points Points can have Inaccurate
Locations
Difficult to quickly view the latest inspections / current status.
Began Using Survey123 before the ability to use ArcServer Feature Services.

Great Outdoors: Tech Stack
• Apache Solr (Search)
• Material Design (CSS, styling)
• Angular (JS Framework)
• Leaflet (Mapping Library)
• Gitlab (code versioning and issue management)
• OSM basemap (self-hosted & styled)
• ArcGIS Server (poly, line overlays)

Great Outdoors: Data Maintenance
• Each “steward” (DNR, Met Council, Greater Minnesota Regional Parks & Trails Commission) has a secure data maintenance site through AGOL
• Can add, remove, modify, add photos, etc
• Everything goes through extract, transfer, load (ETL) overnight and shows up in the app the next day
• Questions?

Local Update of Census Addresses (LUCA)
• MnGeo submitting for counties that declined or not registered
• Working with cities within counties that might not be covered
• Will share knowledge as best as we can (can’t share the Census data)
• Brent Lund (PM), plus two Student Workers
