Flood Insurance Studies · digitized

The data inside FEMA flood studies, finally usable.

FEMA Flood Insurance Studies hold the numbers floodplain work depends on — flood profiles, discharge tables, base flood elevations — locked inside scanned PDFs. FISExplorer reads them back out: ask questions with cited answers, pull tables, and lift coordinates straight off a flood profile by clicking the curve.

01 · READ

OCR on scans

Scanned, decades-old studies turned into searchable, machine-readable text.

02 · ASK

Cited answers

Ask in plain language. Every answer links to the exact page it came from.

03 · EXTRACT

Tables out

Discharge and floodway data tables rebuilt as clean, downloadable data.

04 · DIGITIZE

Profiles to points

Click along a flood profile to lift station–elevation coordinates to scale.

How it works

From a locked PDF to data you can work with.

A study moves through four stages. Each one turns a piece of the document — text, tables, plots — back into something you can search, cite, or download.

STAGE 01

Page capture

Every page is imaged and assessed — text or scan — so the right reader is used on each.

STAGE 02

Text & OCR

Modern OCR pulls clean text from scans, then it's indexed for grounded, cited search.

STAGE 03

Table rebuild

Discharge and floodway tables are reconstructed into structured, exportable form.

STAGE 04

Profile digitizing

Flood profile plots are placed on their real axes so any point reads as station and elevation.

Access

Reading is free. Taking the data with you is the paid part.

Explore any digitized study, ask questions, and read cited pages at no cost. When you need the numbers in your own workflow — exported tables, digitized profile data — that's where it's paid.

Early access

Request a study, free for now.

Tell us the community or county you need, and we'll digitize that study and send you access — usually within a day or two. It's free while we're getting started; we'd rather you see the work than pay for it yet.

No charge during early access · we'll only email you about your request
