I have created my map in Tableau, with on it some locations (buildings) of interest. However, with the standard satellite background map, it is not really possible to see the (roofs of) buildings in full detail.
How can I get more detailed satellite maps as my background?

I wouldn't ask if I had not searched a way for the whole day - so my problem is, that i have multiple raster files (>300) that show different flooding of cells in each iteration step (so not strictly a time series, but close). I want to display the results on a hillshade (that remains the same) of every raster and export it to a png. My goal is to animate them using one layout in ArcGIS Pro, where only the active raster layer should change on every export and then animate the exported png files to one GIF or video file!
How is this possible in ArcGIS Pro 2.8?? Or QGIS?
ArcGIS Pro Animation tools are not working for this scenario (because I dont have feature classes and/or time series data) and QGIS seems to only work with change of extents in Atlas (or time series with time data as well). In ArcMap there used to be a tool called Group Animation, which does exactly what i want to do ...
Any ideas? Maybe a python script? Any hints on that?
Very appreciated!

I have tried out the ArcGIS Pro Animation tools which apparently need time series data or feature classes (which I dont have). QGIS Atlas also seems to only work with varying the extent of the image on every iteration...
I'm looking for sample code, or getting started to perform a "green screen" with the latest Azure Kinect DK.
How should I proceed to build and display a color stream with ONLY body area ?
Is it possible to avoid using body stream ? Because it require a stronger (NVidia computer)
We just published the new Green screen code sample as part of our GitHub open source repo microsoft/Azure-Kinect-Sensor-SDK.
You can find more information at green screen example
If you have any questions about the code, you can open GitHub issue.
I just received my Azure Kinect device recently and have not yet tried a few things I am interested in so this reply comes not from direct experience, however sample code and the SDK's indicate there may be a viable approach.
You can always try to implement traditional color-recognition algorithms, but if your usage scenario allows it, you can use data from the depth camera to filter only data within a depth range, with the "green screen" being out of range. You can then correlate pixels from the depth camera to the RGB image data to pick out data from the color stream that is within a certain depth range. Also, the background does not have to be a real green screen, but rather just has to be outside of the filtered depth range.
This approach allows you to use the sensor SDK, not requiring the body tracking SDK and its associated GPU requirements.
I am using Cesium, and I would like to make a 3d city representation.
I would like to retrieve a .json of the current location I am from OpenStreetMap.
I have the position and the altitude of where I am.
The problem is that I do not understand/can't find from which url source I can retrieve buildings ID and their relative height for a defined tileset position in openstreetmap
I found a lot of exemple on internet and lib that do this, but I need to do it from source, and I do not quite know how.
Basically, how does for exemple this : https://osmbuildings.org/ get the data from
OSM has the data that's necessary to set up such a service, but the various providers use different formats as there's not really a clear standard yet (unlike with 2D raster and, arguably, vector maps). For use with Cesium, you probably want Cesium 3D Tiles.
Cesium is offering their own building layer based on OSM data, called Cesium OSM Buildings (no relationship with OSM Buildings), on their Cesium Ion platform. It does not fully support the OSM data model at this point, but the Cesium integration is obviously well done.
I'm not sure what OSM Buildings is currently using, but it does not seem to be the same as Cesium's 3D Tiles. Some older info on GitHub mentions using GeoJSON, but looking at the network traffic, it now seems to be using Mapbox Vector tiles, which is not a format specialized for 3D data, but rather a general-purpose solution for transmitting OSM data (and other data sources) as tiled vector maps. On osmbuildings.org/data, they mention that they are willing to provide data in other formats for commercial customers, though, if that's an option for you.
Finally, some people have experimented with providing OSM for Cesium using open source software (see e.g. the osm-cesium-3d-tiles and osm2cesium repos). This might be a starting point for setting up your own service if you're willing to go down that path, but it's definitely not a complete and polished solution at this point.
I am creating simple application for altering an image projected by projector.
I would like that projected image to be different than the desktop.
Consider simple example. My application would take a print-screen and add some bitmap to it. Than it will displayed on the projector. While original image on notebook monitor is the same, the projected image will contain this added bitmap.
I am using GDI for altering image the image in C++/CLI, and Windows Forms.
You just create two windows, and position one such that it's on the secondary display, and one such that it's on the primary display. There's nothing "magical" about the second monitor you have to mess with.
I'll add to what Billy said, and provide information that you should use Screens collection for that. It will give you exact coordinates of each screen that is available on the system.

I've been asked to create a stand-alone site/app that's not connected to the web (all on a local server).
One part of it is to have a map of a natural reserve with a bunch of links that will show footpaths, different animals habitat areas, visitor centres and such.
So there's a map (static picture) and when you click on it some overlay goes on top of it.
At least that's the way I see it now.
I've looked here: http://www.carto.net/williams/yosemite/ but it just looks mucho ugly.
Getting Maps Premium is not an option as it's not that cheap. And the reason they don't want to use Maps/Earth free API is because internet connection is still very slow there (sattelite internet only and when optic cable will be hooked up nobody knows).
Looking for some recommendations as to how to proceed there. Drawing paths/areas on the picture of the maps seems extremely insufficient and time consuming.
I'd need some way to use coordinates to automatically draw areas and lines over the map (and then somehow export that as a graphis file (or SVG) that'll be layered on top of original map simply using ajax.
Will ARCGIS pro edition be the way to go or should I start learning SVG. Do you know some good SVG books/tutorials (as related to mapping)? Maybe there's some other way around altogether...
They do have detailed maps of the area in ARCGIS (whatever format they are in I don't know yet).
Just looking for some ideas, any help will be appreciated. Thanks in advance.
Do you know GeoServer? More or less all-in-one, compatible with different types of datasets, widely customisable.
Starting from "raw" SVG and write the whole thing yourself will probably be prohibitively time consuming.
If you have very little data (say less than 50 geometries) that is fixed, you could also use OpenLayers without any backend server.
For the data you could use a OpenLayers.Layer.Image if your (overlay-) map consists of a small raster image. For vector data, you can use OpenLayers.Layer.Text or a OpenLayers.Layer.Vecor together with protocols OpenLayers.Layer.KML or .JSON.
You can click through the current release examples.
I admit that this is not an easy task for a beginner, but it's fun hacking the maps together.
