Getting Started
Step by step guide
The following guide will help you understand, Step-by-step the best practices of how to work with the Map Colonies 3D Catalog and how to consume mapping products in a dynamic way (materials might be changed or added)
Flow diagram
Query CSW catalog (Step 1)
Query 3D CSW catalog service to find item(s) according to desired filter example are here
Filter should be based on 3D profile
Example query based on mc:classification profile field

info
Authentication must be integrated in order to communicate with 3D Tile and Catalog services.
See the principles here
Get layer URI (Step 2)
In the Response, look for
Extract link for desired 3D model
<mc:links scheme="**3DTiles" name="">
http://3d-model-server.com/path-to-tileset.json
</mc:links>
info
You need to save <mc:links> element value as MODEL_URL, which is a layer consumption URL.
Get terrain provider URI (Step 2.1, optional)
In the Response, look for
Extract link for terrain provider
<mc:links scheme="TERRAIN_QMESH" name="srtm100">
http://tiles.com/terrains/srtm100/layer.json
</mc:links>
info
You need to save <mc:links> element value as TERRAIN_URL, which is a terrain provider consumption URL.
Step 3
Construct Client side Layer
Now, after you got all product metadata that you need by querying our Catalog and MapProxy capabilities, lets actually use it in order to display it in real map viewer / application (clients).
warning
Below examples are based on Pseudo code, you will have to adapt it in your own application to make it work.
Cesium
info
The minimum required version for cesium is v84.
// **Optional** add to Cesium terrain provider in order to clamp 3d models to the ground
viewer.terrainProvider = new Cesium.TerrainProvider({
url: new Cesium.Resource({
url: "<TERRAIN_URL>",
queryParameters: {
"token": "<token>",
},
}),
});
...
...
// Add 3d model to the scene
const tileset = viewer.scene.primitives.add(
new Cesium.Cesium3DTileset({
url: new Cesium.Resource({
url: "<MODEL_URL>",
queryParameters: {
"token": "<token>",
},
}),
})
);
...
Replace <MODEL_URL> with the URL link that you got from Step 2.
Replace <TERRAIN_URL> with the URL link that you got from Step 2.1 (optional).
Replace <token> with the token you have.
