Check this out, they have samples on the "try now page". No limits on size, LiDAR and other xyz data types in the web browser, with no plugins and polished WebRTC collaboration. This company has been privately virtualizing substations for big energy companies building this software out for over three years, and then they added this LiDAR steaming service ...

Using OpenStreetMap you can compute the building height through some tags on buidings. As you can see there is an extrusion in Bucharest (and whole world) in this 3D simulation: http://demo.f4map.com/#lat=44.4379244&lon=26.1004697&zoom=18. Note that the accuracy of the height of buildings is random and some buildings does not have height relative ...

The very first thing you need is a slope raster, which is created from a DEM - see 8.3.3 here. To solve the first part of your problem, the average slope, you need a zonal statistics tool. This provides statistics of one raster's cell values based on areas defined by polygons or cells of constant value in another raster. There is a QGIS Zonal Statistics ...

The best way to calculate several statistics for your raster layer is to use Focal Statistics from Spatial Analyst provided by ArcGIS!

Answer to question 1: it is possibly appropriate, and there are alternatives, and some of them have been implemented rather recently in gstat, see this vignette. Q 2: there is a function zerodist in sp; if the collocated data have different time stemps, it should not be a problem if you do proper ST kriging. Q 3: if gstat is informed that coordinates are ...

Maybe you could rely on osm2x3d project. Demo here: http://web.osm2x3d.net The main feature is to convert osm xml data to x3d format (3D scene graph). Also using x3dom js library, it allows to render the result natively in a web browser.

While looking for a similar device to determine birds position in flight, I found the TruPulse 360. This laser range finder gives you the information you need and it stores it directly on a computer. But as it's quite expensive and regarding birds probably only works for 500 m I am going to try the Solmeta Geotagger.

The QGIS threejs plugin is able to turn OSM data into 3D: http://www.cartografia.cl/beta/index.php/home/sig/891-generar-edificaciones-en-3d-a-partir-de-un-shapefile-con-qgis Another chance is povray: http://wiki.openstreetmap.org/wiki/User:Maxbe/Relief_mit_POVray http://blog.openstreetmap.de/blog/2012/01/wochennotiz-nr-80/ You might need Google translate ...

I suggest my new project: osm2x3d. My code is c++. It transforms osm data (xml) to x3D data (xml).

And here how to make it 3d; you should create a field with a name "Elevation" and then calculate the values of the elevation or contour data to this field. After you have this data (shape or whatelse) just use "export to cad" tool on ArcToolbox. You will reach to the 3d dwg data. If you don't have "elevation" field on your shape file you can never get the ...

What sort of transformation options are available to you depends on whether the LiDAR data in question was collected by a terrestrial (fixed position) scanner or some sort of mobile or airborne platform. If it was collected terrestrially, the answer also depends on whether the data you are speaking of was collected from one scan or multiple scans. Below I ...
