01 the starting point
BIG PARKING LOTS. MANUAL DISCOVERY.
PILLAR sells solar carports into large German parking assets. Finding candidates meant stitching OpenStreetMap exports, area filters and gut feel — slow, inconsistent and impossible to refresh weekly at scale.
02 what we built
A WEEKLY PARKING ENGINE WITH SCORING.
An automation pipeline ingests German parking lots, applies area and carport signals, scores priority and publishes refreshed maps the sales team can filter — on a weekly cadence.
-
01
INGEST
OpenStreetMap parking assets merged into a master dataset.
-
02
FILTER & SCORE
Keep lots from 5,000 m² up, score sales priority, flag carport potential.
-
03
REFRESH
Weekly refresh of the prospect map for the sales team.

04 the footnote
SALES STARTS
WITH A MAP.
Instead of analysts rebuilding parking lists by hand, the team opens a refreshed prospect map: 40,594 large lots and 6,456 high-priority rows, ready for field planning without inventing pipeline numbers we have not measured.

FOR B2B TEAMS SELLING ON GEO DATA.
High-ticket field sales where the first bottleneck is finding the right locations — not writing outreach yet.
- You need a living map, not a one-off CSV dump
- Priority scoring beats scrolling OpenStreetMap by hand

07 asked about this case
Where does the parking data come from?
OpenStreetMap parking polygons, cleaned and merged into one Germany-wide master map with weekly refreshes.
Did you measure outreach or revenue from this map?
No — this case covers the research system and map metrics only. We do not publish pipeline € we have not audited.
What makes a row high priority?
A composite priority score of 80+ on top of the 5,000 m² filter — 6,456 rows in the 13 Jul 2026 snapshot.
How often is the map refreshed?
Weekly. Sales always opens a dated snapshot, not a stale export.
