This week I explored the Delaware County Ohio GIS Data Hub and reviewed the available datasets under the “All Files” section. After reading through the data summaries, I downloaded the Parcel, Street Centerline, Hydrology, and Township Boundary shapefiles. I extracted the files and added them into ArcGIS Pro so I could look through the attribute tables and better understand what information is attached to each layer.
The Parcel layer is the most detailed dataset. It includes property boundaries across Delaware County and contains a large amount of attribute information, such as parcel identification numbers, ownership details, and land use classifications listed in the “class” field. This dataset will be especially useful for spatial selection and land-based analysis.
The Street Centerline layer shows the county’s road network, including road names and classifications. This will help provide reference on maps and will also be useful for buffering and proximity analysis.
The Hydrology layer includes streams and other water features throughout the county, which will support environmental and spatial relationship analysis. The Township Boundary layer defines township limits and will allow me to focus analysis within a specific administrative area.
For my final project, I plan to focus on Concept 3 (“What’s Inside?”) and Concept 4 (“What’s Nearby?”). These concepts will allow me to examine how parcels relate to township boundaries and water features, as well as analyze proximity to roads and streams using buffers. Overall, these datasets provide a strong foundation for meaningful spatial analysis in Delaware County.
