Your vendor list, ranked by the hazards each site sits in.
Supply Chain Hazard Mapping screens every supplier site once a year for flood plain, wildfire fuel load, landslide terrain and storm surge exposure from high-resolution imagery4, and hands back a numbered register you can take to renewal.

Where the flood-zone spreadsheet runs out
The vendor list comes over from procurement and you need a hazard column on it before renewal. So each address gets looked up against a flood zone map and the result is pasted in. Some of those addresses are head offices, and some are a unit in a park where the building you care about is at the far end of the lot.
Wildfire and landslide are either blank or a separate job nobody has started. The sheet goes into the committee pack, and someone asks which sites are actually in the worst spot and why. You have a column of designations and no way to show your work.
The renewal-cycle screen, step by step
| Step | The spreadsheet | With Supply Chain Hazard Mapping |
|---|---|---|
| 01Fixing the site list | You take the vendor export and work out which address is the plant and which is a registered office. | You send the site list and we screen each site at its boundary, flagging any entry we cannot place on the ground. |
| Still yours: Knowing which suppliers matter to you and which sites are critical. | ||
| 02Which hazards get checked | Flood zone gets looked up. Wildfire and landslide get done where someone has time, which is often nowhere. | Every site is screened against all four: flood plain, wildfire fuel load, landslide terrain and storm surge. |
| 03Reading the site, not the address | The lookup is made at the address point and says what the map says for that point. | The call is made against current imagery and terrain around the site boundary, so the lot is looked at.4 |
| 04Ranking | You sort by the flood zone column and apply judgement to the rest. | Each entry carries an exposure tier by hazard, and the register is ranked by it, so the sites in harm's way sit at the top.5 |
| Still yours: Deciding which tier needs action, and weighing it against spend and how critical the supplier is. | ||
| 05Showing your work | A cell reading "Zone X" and a PDF that was current when someone downloaded it. | A basis note on each entry says which imagery and terrain layer supported the call. |
| 06Quiet sites | A site with nothing flagged looks the same as a site nobody checked. | A site with no signal is entered as "no exposure identified" for that hazard. It is never left off. |
What the register holds
- 3.1Register entry
Ranked entries
One numbered entry per site with its hazard type(s) and exposure tier, in rank order. This replaces the ranking and the hazard column in the sheet, and is where the renewal conversation starts.
Row: Ranking - 3.2Summary page
Portfolio view
How many sites fall into each hazard category, so concentration is visible at a glance when the risk committee asks. It follows from the ranking step.
Row: Ranking - 3.3Per-entry note
Basis notes
The imagery and terrain layer behind each call. This is the answer to "why is this one a high tier", and replaces the flood zone designation sitting alone in a cell.
Row: Showing your work
Pilot, start to register
You supply the site list and we return the register. The pilot is a defined set of sites, so you can see an entry built before you commit the whole footprint.
The site list
Send the supplier sites for the pilot, with whatever location detail you have. Tell us which ones are critical.
Imagery and terrain
We pull current high-resolution imagery and terrain context for each site.
The hazard screen
Each site is checked against flood plain, wildfire fuel load, landslide terrain and storm surge. A cloud-affected pass waits for the next usable one before the entry is finalised.
The register
You get numbered entries ranked by exposure tier, the portfolio view and the basis notes.
Limits
It is a screen
This is an imagery and terrain screen. It is not a certified hazard assessment, an engineering report or an insurance survey, and it should not be filed as one.
Annual, not continuous
The register is one screen per site per year. It does not watch for new hazards between screens. A site added mid-cycle can be added on request.
Clouds
Optical imagery needs a usable pass. Cloud over a site delays its entry until the next clear one.
Resolution floor
At 0.5–2 m a pixel is roughly two to six and a half feet across. Lots, buildings, vegetation patches and slopes show up. A single culvert, a loading dock set below grade or a drainage detail does not, and the register makes no claim about them.
Tiers are classes
An exposure tier is a class. It gives no probability, no loss estimate and no confidence percentage.
What imagery can't see
Storm surge and flood plain calls lean on terrain, and conditions underground or inside a building are not visible from above. Those stay with a site survey.
Who it's for
Switch if
- You are a risk manager or procurement lead with a vendor list and no ranked view of physical hazard
- Your committee asks why a site is rated as it is and you need a basis to show
- You want wildfire and landslide in the same register as flood
Stay with the spreadsheet if
- You need a certified assessment or an insurer-accepted survey
- You need continuous or real-time monitoring of your sites
- You need engineering-level detail on a single critical facility
Questions before a pilot
Is this a certified hazard assessment?
No. It is a screen built from imagery and terrain. It does not replace an engineering or insurance report.
Does this replace the flood zone lookup?
It replaces the spreadsheet as the ranking. If your insurer or lender wants the flood zone designation, you still supply it.
How do we check it against what we know?
Pick a handful of sites you already know well and compare our entries with what you know of the ground. Include some you expect to come out quiet.
How current is annual?
One screen per site per year. A site added mid-cycle can be added on request.
Does cloud cover matter?
Yes. A cloud-affected pass is retried on the next usable one before the entry is finalised.
What about sites with no visible hazard signal?
They are entered as "no exposure identified" for that hazard. They are not left off.
What do we send and what comes back?
You send the site list. You get the numbered register, the portfolio view and the basis notes.
Will it open in our risk tool?
The register comes as a spreadsheet or CSV and a PDF. We do not write into your procurement or risk systems.
Who owns the imagery and the register?
Ownership and licence terms are agreed in writing when the pilot starts. If your legal team needs them earlier, ask.
How is it bought?
Tell us the size of the list and we will scope a pilot to it. Terms are agreed when the pilot is scoped.
Get your footprint ranked.
Send a pilot set of supplier sites. We will show you what an entry looks like for each.
