Plan corridors and inventory assets in the field
Transportation, transit, and logistics planners spend their days reconciling road centerlines, right-of-way limits, asset inventories, and field condition notes that live in separate CAD files, agency portals, and clipboards. Smart Site Plan puts the TIGER road network, parcels and ROW, your imported route and asset data, and field condition surveys on one map so a corridor study or an asset inventory runs in days.

Real Transportation work over Polk County, NC, captured in the product
The old way
A corridor study starts by pulling the centerline file from one drive, the ROW limits from recorded plats, the asset inventory from a spreadsheet, and the condition notes from last month's clipboard. Stitching those into one picture takes weeks, and the field data is stale by the time an alignment is drawn.
With Smart Site Plan
Map every corridor, ROW, and asset on one platform
The data, already on the map
Drawn from 20 million open datasets, one click each. No agency portal hunting, no format wrangling.

How Transportation work gets done
End to end, in the browser, on one map.
Corridor alignment study
- 1. Open Data
Add Census TIGER roads, parcels with right-of-way, recorded easements, and NHD stream crossings scoped to the corridor.
- 2. Import
Load the existing centerline and utility files reprojected from State Plane to WGS84 to anchor the study to as-built geometry.
- 3. Draw
Draw two or three candidate alignments with live length readouts and offset the ROW setback along each.
- 4. Measure
Measure corridor length, stream-crossing distances, and the area of each affected parcel to size the takings.
- 5. Share
Send the steering committee a share link to the alternatives.
District asset condition inventory
- 1. Import
Load the sign, signal, and culvert inventory from CSV or Shapefile, up to 50,000 features on a single layer.
- 2. Forms
Open a condition survey form at each asset to score pavement, retroreflectivity, or structure rating in the field.
- 3. Photos
Attach geotagged photos pinned to the exact asset so the defect is documented at its coordinate.
- 4. GPS
Track the crew's route so every surveyed segment is logged and gaps in coverage are obvious.
- 5. Export
Export the scored inventory to GeoJSON or, on Pro, CSV to feed the agency's pavement or asset management system.
Logistics routing and stop review
- 1. Open Data
Add the TIGER road network and Census demographics across the service territory.
- 2. Import
Bring in delivery stops and depot locations from a CSV of addresses and coordinates.
- 3. Smart Query
Filter stops by volume, window, or zone to find the segments that drive the most cost.
- 4. Style
Color stops and route segments by load or service tier so the heavy corridors read at a glance.
- 5. Share
Send dispatch a view-only link to the flagged stops so the planner and dispatch work from the same map.
What you can do
Build the corridor base map from the road network
Add Census TIGER roads scoped to the study area, then drop parcels and right-of-way boundaries underneath to see where the alignment sits against private ownership. Layer FEMA NFHL flood zones and NHD stream crossings so you flag every drainage and floodplain constraint before the alignment is fixed.
Import route and asset inventories you already have
Bring in centerlines, sign and signal inventories, culverts, transit stops, or pavement segments from Shapefile, DXF, GeoPackage, GeoJSON, CSV, or GPX, and we reproject from State Plane, UTM, or any EPSG code to WGS84 on the way in. Up to 50,000 features per layer means a full district asset inventory loads onto one map without thinning it down.
Draw alignments and measure corridor length
Draw candidate centerlines, station-to-station segments, and setback offsets with a live length readout as you go, so each alternative carries its own running mileage. Measure corridor length, crossing distances, and parcel takings directly on the map rather than scaling them off a PDF.
Capture field condition surveys on any device
Send crews out with custom Forms to score pavement, sign retroreflectivity, guardrail, or stop condition, with GPS logging the route and geotagged Photos pinned to the exact asset. Drafts fill offline in a dead zone and submit on reconnect, so a windshield survey comes back as map-ready data, not a clipboard to retype.
The capabilities Transportation teams lean on
TIGER roads & ROW
The Census TIGER road network, parcels, and right-of-way boundaries load straight onto the map so an alignment sits against real ownership from the first sketch.
Condition surveys & GPS
Crews score assets in custom forms with GPS and geotagged photos, and drafts submit on reconnect, so a windshield survey returns as map-ready data instead of a clipboard.
Corridor length & takings
Draw alignments and measure corridor length, crossing distances, and parcel areas with live readouts, so each alternative carries its own mileage and takings without scaling off a PDF.
Asset import & handoff
Bring centerlines and asset inventories in from Shapefile, DXF, or CSV reprojected to WGS84, then export scored data to GeoJSON or CSV on Pro for the agency's asset management system.
In practice
A planner studies a Salt Lake County corridor and inventories its assets
A corridor planner in Salt Lake County, Utah, has two weeks to compare alignments for a widening project and inventory the signs along the existing route. The study adds Census TIGER roads, parcels with right-of-way, and NHD stream crossings, plus the as-built centerline imported from the Utah Central State Plane zone, and two alternatives are drawn with live length and parcel-area readouts to size the takings. A crew then runs a sign-condition form, with GPS tracking the route and geotagged photos pinned to each post, and the survey comes back the same afternoon as map-ready data for the agency's asset system.
What changes
- Build a corridor base map from TIGER roads, parcels, and ROW without weeks of stitching CAD files
- Turn a windshield survey into map-ready condition data with no clipboard to retype
- Carry running mileage and parcel takings on every alignment alternative as you draw it
- Hand committees and asset systems clean shared maps and exports instead of a stack of PDFs
Transportation, answered
Yes. Import Shapefile, DXF, GeoPackage, GeoJSON, CSV, or GPX and we reproject from State Plane, UTM, or any EPSG code to WGS84 on the way in, with up to 50,000 features per layer so a full district inventory loads onto one map.
