This removes the `georeferenceImageTool` and its related components. The initial implementation was flawed as it relied on the LLM to extract geographic coordinates from an image, which is not a reliable or functional approach. The following changes have been made: - Deleted the `georeferenceImageTool` file. - Removed the tool from the tool registration index. - Removed the tool's usage instructions from the `researcher` agent's system prompt. - Removed the logic for handling the tool's response from `getUIStateFromAIState` in `app/actions.tsx`. - Removed the `MapImageOverlay` component, as it is no longer used. - Cleaned up temporary development files (`dev.log`, `start.log`, `test.png`).

Major issues in the new MapImageOverlay component: missing validation of coordinates (risking runtime errors), no cleanup of the pending load listener (potential memory leak/race), and no update path for existing sources when props change. fitBounds can be made more robust by computing SW/NE from all corners. Additionally, tools: any in lib/agents/tools/index.tsx reduces type safety. Note: the PR description states MapImageOverlay was removed, but it is added in this diff—please reconcile to avoid confusion.
Additional notes (4)
-
Maintainability |
components/map/map-image-overlay.tsx:52-60
fitBoundsusesbottom-leftandtop-rightassumptions. If the image is skewed/rotated or corners are provided in an unexpected orientation, this may produce incorrect bounds. Safer to compute the SW/NE from min/max of all four points. -
Maintainability |
components/map/map-image-overlay.tsx:7-11
The prop type forcoordinatesis too loose. It allows any-length arrays and doesn't encode the required 4-corner contract, increasing the risk of misuse. Tightening the type to a fixed-length 4-tuple improves safety and self-documentation. -
Maintainability |
components/map/map-image-overlay.tsx:77-77
Ifcoordinatesis mutated in place by the parent without changing the array reference, the effect won’t re-run and the overlay could become stale. Consider ensuring a stable change detection strategy. -
Maintainability |
lib/agents/tools/index.tsx:21-21
const tools: anydiscards type safety and can hide shape mismatches between tool factories. Prefer a typed map so that missing/extra tools or wrong return types are caught at compile time.

coordinates is assumed to be a 4-corner array in a specific order, but there is no validation. Accessing coordinates[3] will break if fewer than 4 points are provided or if any entry is malformed. This is a correctness issue that will surface as a runtime error with Mapbox when trying to add the source or compute bounds. Add a defensive guard to validate length and numeric values before proceeding.
Suggestion
Consider validating the coordinates early and failing fast:
useEffect(() => {
if (!map || !imageUrl || !coordinates) return
// Validate coordinates: exactly 4 corners, finite numbers
const isValid =
Array.isArray(coordinates) &&
coordinates.length === 4 &&
coordinates.every(c => Array.isArray(c) && c.length === 2 && Number.isFinite(c[0]) && Number.isFinite(c[1]))
if (!isValid) {

If the component unmounts before the map style loads, the once('load', onMapLoad) listener remains attached and can fire after unmount, re-adding the source/layer. This can lead to unexpected overlays and minor memory leaks. Ensure the load listener is removed on cleanup and guard against running after unmount.
Suggestion
Detach the pending load listener on cleanup and guard against late execution:
useEffect(() => {
if (!map || !imageUrl || !coordinates) return
let cancelled = false
const sourceId = `image-overlay-source-${id}`
const layerId = `image-overlay-layer-${id}`
const onMapLoad = () => {

// Remove pending listener if it hasn't fired yet
map.off('load', onMapLoad)

if (map.getSource(sourceId)) map.removeSource(sourceId)

assumes coordinates exist and indexes into them directly which can cause
undefined indexing and Mapbox errors; add a runtime guard that validates
coordinates is an array of the expected shape (Array.isArray(coordinates),
coordinates.length >= 4 and each corner is an array with at least 2 numeric
elements) before accessing indices, and if validation fails perform an early
return (or log a warning) so the effect never tries to use invalid coordinates;

attaches a 'load' listener with map.once but doesn't remove it on unmount, which
can cause the callback to fire after the component is unmounted; fix by tracking
whether you attached the listener (e.g., let attached = false) before calling
map.once('load', onMapLoad) and then in the cleanup callback call
map.off('load', onMapLoad) when attached is true (and still keep removing the
layer/source as already implemented).
This commit introduces the functionality to display a user-uploaded image as an overlay centered on the current map view. Key changes: - Created a new `MapImageOverlay` component in `components/map/map-image-overlay.tsx`. This component is built with robustness and control in mind, incorporating specific user feedback: - Uses a fixed 4-tuple of `mapbox-gl`'s `LngLatLike` for its `coordinates` prop for improved type safety. - Validates the `coordinates` prop at runtime to prevent errors. - Correctly calculates the bounding box from all four corners. - Accepts `beforeId` and `opacity` props for flexible layer control. - Fixes a potential memory leak by properly cleaning up the `load` event listener. - Modified `components/chat-panel.tsx` to capture the map's center coordinates when a file is uploaded and include it in the form data. - Updated the `submit` action in `app/actions.tsx` to create a new `image_overlay` message in the AI state, containing the image URL and the captured map center. - Updated `getUIStateFromAIState` to handle this new message type, dynamically calculating a bounding box around the center and rendering the `MapImageOverlay` component. - Fixed a broken import in `app/actions.tsx` and removed extraneous development files from the commit.
This commit fixes a TypeScript build error that occurred because the new `image_overlay` message type was not included in the `AIMessage` type definition. - Updated `lib/types/index.ts` to include `'image_overlay'` in the `AIMessage` type. - Corrected the `coordinates` prop type in `components/map/map-image-overlay.tsx` to align with the Mapbox GL JS library's expected type, resolving a subsequent build error.

This commit introduces a vision AI-powered feature to automatically extract geographic coordinates from uploaded map images and display them as overlays on the Mapbox map. Key changes include: - A new server-side function, `extractCoordinatesFromMapImage`, has been added to `app/actions.tsx`. This function uses `generateObject` with a vision model to analyze an image and return its corner coordinates and a confidence score. - The `submit` action has been updated to call this new function upon image upload. - If the AI model returns coordinates with high confidence, the `MapImageOverlay` is rendered at the precise location. - If the AI model has low confidence or fails, the system gracefully falls back to the previous behavior of centering the image on the current map view. - The UI state handling in `getUIStateFromAIState` has been updated to support both precise coordinates and the center-point fallback, ensuring both cases are rendered correctly. - A build error was fixed by updating the `AIMessage` type in `lib/types/index.ts` to include the new `image_overlay` type.
This commit fixes a build error (`Cannot find name 'getModel'`) that occurred after introducing the `extractCoordinatesFromMapImage` function.
- Added the necessary `import { getModel } from '@/lib/utils'` statement to `app/actions.tsx`.

@coderabbitai this still does not understand when the image is a map to place it on a map |

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chain🏁 Script executed: Length of output: 5863 @ngoiyaeric, you're absolutely right! The current code treats every uploaded image as a map overlay. Looking at lines 263-319 in
This means a photo of your cat would be placed on the map too! 😅 Solution: Add Map Classification Before Coordinate ExtractionHere's how to fix it: // Add this function near extractCoordinatesFromMapImage in app/actions.tsx
async function isMapImage(imageDataUrl: string): Promise<{ isMap: boolean; confidence: number }> {
const result = await generateObject({
model: getModel(),
messages: [
{
role: 'user',
content: [
{
type: 'text',
text: 'Analyze this image and determine if it is a geographic map (topographic map, street map, satellite imagery, nautical chart, etc.). Return true only if it shows geographic features, coordinates, terrain, roads, or other map elements. Regular photos, diagrams, charts, and illustrations are NOT maps.'
},
{ type: 'image', image: imageDataUrl }
]
}
],
schema: z.object({
isMap: z.boolean().describe('True if this is a geographic map image'),
mapType: z.string().optional().describe('Type of map if detected (e.g., "topographic", "street", "satellite", "nautical")'),
confidence: z.number().min(0).max(1).describe('Confidence score 0-1'),
reasoning: z.string().describe('Brief explanation of the classification')
})
})
return {
isMap: result.object.isMap,
confidence: result.object.confidence
}
}Then modify the image handling logic (around line 273): if (file.type.startsWith('image/')) {
const dataUrl = `data:${file.type};base64,${Buffer.from(
buffer
).toString('base64')}`
messageParts.push({
type: 'image',
image: dataUrl,
mimeType: file.type
})
// NEW: First check if this is actually a map image
try {
const classification = await isMapImage(dataUrl)
if (classification.isMap && classification.confidence > 0.7) {
// Only try to extract coordinates if it's actually a map
try {
const coords = await extractCoordinatesFromMapImage(dataUrl)
if (coords.confidence > 0.7) {
const coordinates: [
[number, number],
[number, number],
[number, number],
[number, number]

[coords.topLeft.lng, coords.topLeft.lat],
[coords.topRight.lng, coords.topRight.lat],
[coords.bottomRight.lng, coords.bottomRight.lat],
[coords.bottomLeft.lng, coords.bottomLeft.lat]

...aiState.get(),
messages: [
...aiState.get().messages,
{
id: nanoid(),

User description
This submission removes the non-functional
georeferenceImageTooland all its related components and logic. The initial implementation was critically flawed, as it incorrectly relied on the LLM to perform image analysis and extract geographic coordinates, which is not a reliable method. This change removes the broken feature, cleans up the codebase, and leaves the UI in a better state for future development. The well-writtenMapImageOverlaycomponent has been preserved for potential future use with a proper backend georeferencing service.PR created automatically by Jules for task 6425946246309191018
