Pocket Fiche — Community Parcel Selection Guide

What is this?

This is a parcel selection map for Pocket Fiche, an ultra high resolution slide made of 500×500 pixel parcels. After the campaign ends, this patchwork of images will get etched onto golden fiches at a resolution of 1μm per pixel.

Each backer of Pocket Fiche will get to claim a 500 x 500 pixel area on the golden slide. This giant patchwork of 1000 images will be etched into every Pocket Fiche and distributed widely.

If you end up canceling your pledge or downgrading to Pocket Field, your parcel will be released for others to claim.

Rules

Each parcel is exactly 500×500 px.
Images are displayed as 1-bit black/white. Uploads with more colors are flatened.
Transparent pixels are treated as white.

Using the Map

Navigation

Scroll or pinch to zoom. Drag to pan.

Editing Your Parcel

Hover your claimed parcel to see actions.
Upload a 500×500 image; non-bitmap images are automatically dithered to black/white.
You can re-upload anytime to update the parcel.
Use Unclaim to free it (be sure, this releases it for others).

Multiple Parcels

If your account has multiple parcel slots, you can claim more than one. Your parcels list appears in the top-left panel of the main map. Click an address there to jump to it.

Address Labels

Each parcel shows its address (e.g. A:1) at the bottom-left and is not editable and will appear on the final golden slide (for navigation purposes). Addresses are column letters + row number.

Tip: If you don’t see hover actions, zoom in to level ≥ 0 and make sure the parcel is inside the circular region.

Create a 500×500 Black–White Bitmap

To get the cleanest result, start and finish in black/white. If you upload a grayscale or color image, the server will dither it to 1-bit. When the golden slide is made, black pixels will be dark (gold pixls blocking light) while white pixels will appear bright (letting light through).

Troubleshooting

I can’t claim a parcel

Make sure you’re signed in.
Only backers of Pocket Fiche will received a login.
Stay inside the circular region; parcels outside aren’t claimable.

I can’t zoom out to see the whole slide

Yup.

My image looks “dotty”

That’s dithering. Uploading pure black/white artwork avoids extra dots.
