Parallax

The instruments Parallax builds for the work.

Parallax builds its own instruments for counter-archiving: six small applications, each sharpened for one part of the method. Five are the working tools. The sixth, Casebook, is the case file that holds an investigation together.

They share one language, so a place fixed in one is the same object a witness stands beside in another. Each runs entirely in the browser, on your own machine, with nothing uploaded.

01The instruments

Five for the work, one for the case.

Each tool does one kind of work well; together they read an image, a testimony, and a landscape as evidence.
/ 01

Sightlines

Where and when

Places photographs and video in space and time, then crosses the sightlines of several images until multiple views of one place fix its position. The instrument for reconstructing a single incident or site.

  • Resection by crossing sightlines
  • Terrain, sun, and shadow
  • A shared, synchronized timeline
/ 02

Atlas

The image complex

Draws many images of one place, object, or event into a single relational field: a montage plate, a graph of how the pictures relate, a map of where each was taken, and deep-zoom close looking.

  • Montage plate and relation graph
  • Camera positions on a map
  • Deep-zoom close reading
/ 03

Situated Testimony

Witness, placed

Anchors a spoken account to a 3D model and a map, statement by statement, so a witness's words sit in the space they describe. Where a document is missing, placed testimony stands in its stead.

  • Testimony bound to a 3D scene
  • Statements anchored in place
  • Sovereignty over the account
/ 04

Verification

Source criticism

A workbench for testing whether an image is what it claims to be: the claim, the checks against it, and a reasoned verdict, with tools for locating and dating a picture from its own content.

  • Claim, checks, and verdict
  • Inverse chronolocation
  • Pixel-level forensics
/ 05

Groundtruth

From orbit

Compares satellite imagery of one place across time to measure what changed on the ground: vegetation, burn, and built fabric, read date against date.

  • Live Sentinel and Landsat retrieval
  • Vegetation and burn indices
  • Change measured between dates
/ 06

Casebook

The case file

The sixth binds the other five. It gathers their finished work into one investigation, on a shared map, timeline, and register of findings, and publishes the whole as a single page.

  • One map, timeline, and findings register
  • Each source bound by its hash
  • One consent-cleared dossier

How they fit together. Each working tool exports its findings in the same format. Casebook reads those exports, lays them on one map and timeline, and can also open a fresh piece of work in any tool already filled in with what the case knows. An investigation moves from a single instrument to a whole case, and out again as one publishable account.
