pls, why no satellite osm map (aha, with add draw polygon place tool like in wikimapia) — saving $21k payment for Google for Google maps layer or just limited uniqe design. As of now i cannot see the same way as i can «describe the world» in wikimapia in other web places

Ah, now we get to the real pain point. You've perfectly identified the gap that Wikimapia filled and why its slow death is so frustrating. Let's break down why there's no direct «Wikimapia clone» with satellite and simple polygons, and then I'll show you the closest existing solutions.
Why No Direct «Wikimapia with OSM Satellite»?

The $21,000 Google Bill (And Others): You nailed it. Providing a free, globally-available satellite layer is astronomically expensive. Wikimapia likely used:

Bing Maps/Here/ESRI imagery: They have (or had) more permissive «free for non-commercial use» tiers for small projects. These tiers are often revoked or limited as companies tighten budgets.

Their own limited cache: They might have bought small batches of imagery for popular areas years ago and are just serving those outdated tiles.

OSM-based projects can't just use Google/Bing satellite freely. They'd get a cease-and-desist letter and a massive bill. This is the #1 blocker.

The «Unique Design» is a Legacy Trap: Wikimapia's simple «click-draw-describe» was brilliant for its time (2006). But it created a walled garden. Your description is locked only on Wikimapia's servers. For the modern open-data philosophy (which OSM embodies), this is anathema. OSM's goal is a single, universal, open geographic database that anyone can use, not thousands of separate descriptions locked in different websites.

Technical Debt & Scale: Building and maintaining a global tile-serving infrastructure for both vector data (the polygons) and a satellite base layer is a massive, expensive engineering task. Wikimapia stopped developing; OSM volunteers focus on the data, not on building yet another viewing website with all the bells and whistles.

The Closest Existing Solutions (The «Wikimapia Gap» Bridges)

You want to «see satellite» + «draw a polygon» + «describe the world» in one simple web interface. Here are your options, from closest match to most powerful:
1. Mapillary + OpenStreetMap (The «Street-View & Point» Combo)

What it is: Users upload geotagged photos (like a crowdsourced Google Street View). You can browse these photos on a map.

The «Wikimapia» Angle: While viewing Mapillary photos in the OSM editor (iD or JOSM), you can add missing buildings, roads, and points of interest (POIs) directly based on what you see in the photo. It's the closest to «looking at imagery and describing»: you see a shop in a photo, you tag it shop=bakery and add name=... in OSM.

2. ArcGIS Online / StoryMaps (The «Corporate-Power, Free-Tier» Option)

What it is: ESRI's platform. It has a very generous free tier for individuals.

The «Wikimapia» Angle: You can create a «Map», add a satellite basemap (ESRI's World Imagery is excellent), and use the «Draw» tool to add points, lines, and polygons. Then you can add rich text, photos, and videos to each shape in a pop-up. You can then share this map with a link. It's exactly the «draw-and-describe» workflow.

Crucial Limit: It's your personal map. It's not a collaborative wiki for the world. Others can view it, but editing is limited.

3. uMap (OpenStreetMap's «Draw & Share» Tool) — THE BEST MATCH

What it is: A tool that lets you create custom maps on top of OSM data and save them online.

The «Wikimapia» Angle:

Choose a base layer: OpenStreetMap, Satellite (ESRI, Bing options), etc.

Use the drawing tools to add markers, lines, polygons.

Add rich HTML descriptions to each object (text, links, images, YouTube videos).

Save the map, get a link. You can make it public and collaborative so others can edit it (like a mini-wiki for a specific topic/region).

This is the spiritual successor for community projects. Want to map all historical wells in your town? All skateparks? Make a uMap.

4. The «Pure OSM» Editing Workflow (The Long-Term Solution)

This is what you should learn for permanent, universal contribution.

Step 1: Browse. Go to openstreetmap.org. Zoom to your area. Switch to the «Aerial Imagery» layer (it's a button on the right). This is the satellite view.

Step 2: Edit. Click «Edit» (you need a free account). You enter the iD Editor.

Step 3: Draw & Describe. Use the tools to draw an area (like a building footprint). On the left sidebar, you «describe» it using tags. This is the key shift: Instead of a free-text description, you add structured data: building=house, roof:material=tiles, name=.... You can still add a free-text note=... or description=... tag.

Why it's better in the long run: This data is now part of «the map of the world». It will appear in OsmAnd on your phone, in thousands of other apps, and in navigation systems. You're not just making a note; you're improving the fundamental geographic dataset.

Your Action Plan:

For quick, personal «draw-and-describe» maps with satellite: Use uMap or ArcGIS Online. They fill the immediate gap.

To truly «describe the world» in a lasting way: Invest time in learning the OSM iD Editor. Start by adding missing buildings from satellite imagery in your own neighborhood. The «description» becomes precise tags.

Accept the trade-off: The price of an open, free, and sustainable global map is the loss of Wikimapia's completely free-form, story-telling approach. We gain universality and lose a certain type of poetic anarchy.

The digital landscape changed. Wikimapia was a beautiful, chaotic village. The internet now demands open data highways. You can still tell the stories, but you have to use the new infrastructure: structured tags in OSM or rich pop-ups in uMap. The spirit lives on; the toolset has evolved.
