Scan Your Trash vs Geoid Altimeter

Scan Your Trash is a citizen science app that invites you to take part in building the future of recycling. With a simple scan of your plastic packaging, you’re helping scientists train machine learning models to recognize and sort waste more accurately. Plastic waste is everywhere, and it’s complex. Even though reducing and reusing plastic is essential, recycling remains an important part of the solution, especially for the mountains of plastic already in circulation. While much of the sorting process is already automated, parts of it still require manual intervention, especially at the beginning and end. Our goal is to support this process with robots that can automatically recognize different types of plastic. But in order to train these systems, we need a lot of diverse data. That’s where you come in. How It Works 1. Grab a piece of plastic packaging — a bottle, a wrapper, a container. 2. Scan it using your smartphone camera by following the simple instructions in the app. 3. Enter the recycling code if available (usually found inside the recycling symbol). 4. Upload your scan to contribute it to our dataset. Each video helps us build a better, more diverse training set for machine learning. Scan Your Trash is part of a research initiative called RecycleBot, which combines lab data, conveyor belt scans from industrial facilities, and real-world contributions like yours. Together, this data helps us train AI systems that can work in real sorting plants. We believe in transparency and collaboration. That’s why the code of this app and the anonymized dataset it generates will be made open and accessible to researchers, engineers, and anyone interested in solving the global waste problem. Trash-Data should be shared.

Geoid Altimeter is an elevation tracking tool built for field professionals. It applies high-precision geoid models to your smartphone's GPS ellipsoidal height to display a practical "orthometric height" (elevation above mean sea level). Try all features completely free for the first 30 days. Experience the convenience directly on your smartphone. [ Key Features ] - Orthometric Height (H = h − N): Converts the raw GPS ellipsoidal height using national or global geoid models. - High-Resolution Elevation (DEM): Reads terrain elevation for your current location or any pinned point — no need to physically stand there. - Pin & Address Search: Drop a pin or search an address to check the elevation anywhere on the map. - Favorites & CSV Export: Save sites with custom names and export all values (h, N, H, DEM) as CSV. - Model Comparison: View your local model alongside the global EGM96 reference. - One-Tap Copy, Screenshot Share, Transparent Satellite/OSM Overlay, and Compass. [ Supported High-Precision Regions ] Geoid models (orthometric height correction): Japan (Geoid 2024 / GSI), United States (GEOID18 / NOAA-NGS), Canada (CGG2013a / NRCan), New Zealand (NZGeoid2016 / LINZ), Switzerland (CHGeo2004 / swisstopo). High-resolution elevation (DEM): Japan (GSI, 5 m laser mesh), United States (USGS 3DEP), Switzerland (swisstopo), France (IGN RGE ALTI, 1 m). For every other country and region, the app provides seamless worldwide coverage using the global EGM96 geoid and global terrain-elevation data. [ New in 1.4.0 ] - Works beyond coverage: pre-load the national geoid model around you, and elevations stay on that model when the network goes. - Always says which model answered — the national service live, a value saved nearby, or the global EGM96 standing in. - Stand-still averaging: hold still and get a mean with its spread, instead of a single fix that scatters by metres. - Antenna height: set the pole length or how high you hold the phone, and it is subtracted from every GNSS height. - Height difference and grade (% and 1:n) between two saved points, a one-page PDF elevation record, and NGVD29 readings for US drawings levelled before NAVD88.
