I'm looking for a library to draw some network map over OSM or Google Maps
Something like v-network-graph. Perhaps someone will suggest a suitable library. Preferably - for Vue :)

I have a number of lat/lng coordinates that I would like to show 3D images for.
Google Earth API seems to have been closed, so does anyone know if another API I can use?
The coordinates I have are for cities all over the world.
Thanks!
If want to display data on a 3D globe then CesiumJS is your best alternative to Google Earth API. Cesium is an open-source geospatial visualization JavaScript library for creating web-based 3D globe applications. It requires no browser plugins and is cross-platform and cross-device. Cesium uses WebGL for graphic rendering which has been adopted by all major web browsers.
See the online demos to get a sense of what it can do:
https://cesiumjs.org/demos.html
There is an online "Sandcastle" application that has a gallery of code examples and runs the code in the web-browser. You can also change the code on-the-fly and re-run with your changes to test out using the Cesium API.

If you have experience using Google Earth API then there are a number of tutorials and examples showing how to migrate to Cesium:

I need to create a digital map with GPS and routing support for a local tour trail project.
I've got the drawing of the map which looks like the following.
Constraints:
I cannot use Google Map.
I need to support GPS.
I need to show route.
What I think I need to do:
Collect Latitude and Longitude of all the routes in the map?
Collect distance of all routes and intersections
Collect road information
Use A* algorithm to find shortest path
What else do you think I need to do? It will be a small map with 2km radius.
I'd need more specifics to be really helpful here, but to get you started, I'd recommend that you check out following...
QGIS for digitizing your map
PostgreSQL + PostGIS for storing your geospatial data
OpenLayers or Leaflet if you need to publish the map online
You can import GPS data into QGIS (and other systems) using the GPS Exchange Format (.gpx extension).
I need a help about how to get skeleton data from my modified Depth Image using KinectSDK.
I have two Kinect. And I can get the DepthImage from both of them. I transform the two Depth Image into a 3D-coordinate and combine them together by using OpenGL. Finally, I reproject the 3D scene and get a new DepthImage. (The resolution is also 640*480, and the FPS of my new DepthImage is about 20FPS)
Now, I want to get the skeleton from this new DepthImage by using KinectSDK.
Anyone can help me about this?
Thanks
This picture is my flow path:
Does Miscrosoft Kinect SDK provide any API that I can input detph image then return skeleton?
No.
I tried to find some libraries (not made by Microsoft) to accomplish this task, but it is not simple at all.
Try to follow this discussion on ResearchGate, there are some useful links (such as databases or early stage projects) from where you can start if you want to develop your library and share it with us.
I was hoping to do something similar, feed post-processed depth image back to Kinect for skeleton segmentation, but unfortunately there doesn't seem to be a way of doing this with existing API.
Why would you reconstruct a skeleton based upon your 3d depth data ?
The kinect Sdk can record a skeleton directly without such reconstruction.
And one camera is enough to record a skeleton.
if you use the kinect v2, then out of my head i can track 3 or 4 skeletons or so.
kinect provides basically 3 streams, rgb video, depth, skeleton.
I've been working with augmented reality API's lately but haven't been able to achieve irregular shape detection, namely the hand. I want to be able to detect hand shapes through the video/camera and execute code based on hand signs. Does anything like this already exist?
Did you have a look at OpenCV?
These are some of the links I found just using Google: Face Detection using OpenCV, Vision For Robots
I'm looking APIs to get some geographical information. Particularly, I'm interested in GIS layers that depict some semantics like roads, vegetation, buildings. If there is an API to get the type of vegetation, it'd be awesome.
Thanks.
I am not exactly sure what you mean. But if you are looking to download GIS data, I recommend using Quantum GIS (open source - http://qgis.org/). Then use the OpenLayers or OpenStreetMap plugin to download data such as roads, buildings, and possibly vegetation. It is going to depend on how much information exists on that area.
