I want to use UAV to get digital elevation model for geomorphological researching and, while trying finding suitable UAV with reasonable price, I found out DJI Phantom 3. More over, I found it very cheap. So, with additional programming, is it possible to get digital elevation model with DJI Phantom 3 Pro?

I am curious if this consumer UAV can be used to capture imagery for further processing to stitch seamless imagery and to use as input into stereo/photogrametry software to create reasonably accurate 3D point clouds in order to create surface models.   I have no experience with flying these crafts but am interested in obtaining one to add some extra perspective to my .  At the same time I would like to be able to try capturing aerial imagery and extrapolating DEM for small 3D models and site plans if possible.   Can anyone share their experiences with this or the previous models using the default camera?

I have been trying to teach myself QGIS by using this forum and others to help. Most of my questions can be answered by downloading plugins that are available through 3rd party repositories but for some reason I am not able to connect with these. Anyone have any ideas why this is the case?

I am looking to host lidar data on my own server and give clients the ability to view that data through a web browser as a 3D point cloud (file would be in .las format or equivalent), possibly with the ability to measure features.   Does anyone know of an easy to implement piece of software that can do this?  I am not nessecarily looking for open source, and I would prefer something plug and play because I am not a programmer.

I'm wondering if there's any addons or online libraries of materials I can download. I've found one called , but then discovered it was from 2008 and thought by now something like that might already be integrated into Blender.

How can I make a plane always look at camera? Like in old videogames, like Doom or Wolfenstein, this kind of software used static images that always looked at the camera, is this possible to make on Blender Cycles?

How can I get more digits in the user interface for modeling.  Of course we can scale up the scene always, but that is just annoying, I like to work in millimeters for example which is possible with the Metric settings in blender, but the UI only shows floating point up to 3 digits?  Is there any way of improving this? Especially the scale in the transform property tab only shows 3 digits, that's annoying :-)

Is there a way to use other computers that are sitting idle on my network to render my images?   From google, I've found , however it appears that is designed to let everyone use your hardware, in exchange for using theirs. Also, there is no guarantee to how soon your project will start rendering.   I have a bunch of servers sitting around that were bit coin mining. Is there a way to use them for blender?

When you fly through your Blender 3D world, you can fly through things. However, sometimes I fly through objects, and before I even get close to them, the objects start cutting off(visually). See image:    How can I stop Blender from doing this? Or at least make it do so, when I get closer to the object?  There are some camera angles that I can't get because Blender cuts away the object in my view/cam

Trying to do some golf course layouts in 2.73a. Would like to use topo elevation info. Currently have grayscale .jpg of site - top view. How do I get this into Blender as a "lumpy" plane?

When taking landscape photos, I often struggle with dynamic range. I have either a burned out skies or landscapes are too dark.  Now I'm reading  that some cameras can take 3 pictures with different exposures, and combine them automatically to one image with higher dynamic range.   So my question is, which cameras have this feature?

I want to try to make a simple 3D map for a small area (10 square miles) with some housing, some roads and some vegetation on it. My geodata is as follows:    shapes with houses/roads/vegetation.  LIDAR point cloud data over the area (can easily be built to a dem). georeferenced aerial image.   Any idea where to start to bundle these geodata together and make a neat looking 3D map?

Is there any way to get blender to render on systems without a GUI?  Over the network on systems with a GUI?  I know of a service that will let you buy virtual servers that are charged by the hour, not the month, allowing to purchase extra performance on demand very cheaply!  The question itself is OS-agnostic, but in this case you can essentially respond in a any OS you would like.

I am seeking closure with this question guys.  I am aware of various sources of free elevation data ~30+ m, and I have been searching for higher resolution FREE data for a while now. This already exists somewhat (), but may have changed since a year.  I'm afraid I may know the answer already, but to put an end to my misery and false hope:  What is the highest resolution, freely available (outside of academic institutions), elevation data covering the ENTIRE UK? - is 10 m available?

So I made a 3d model of a sword, and when I try to render it, the program automatically smooths everything out.   Basically, I looked around online, and made sure everything smoothing related discussed there was turned off, and they all were, what should I do?

I was wondering how you would go about putting a 3D object into a photograph so that portions of the image are:   In front of, or Behind the model.   For example, a photo taken from the roadside with a tree in the foreground.  I want to show a 3D model of a car in the photo on the road but a section of it is not visible because it is obscured by the tree.  Is this possible? If so, how can you do it?  Thanks in advance.

I used to download 1/3 arcsecond elevation geotiffs from extract.cr.usgs.gov using web services.  But a few days ago, that stopped working, probably because USGS reorganized their site.  I tried emailing USGS and haven't heard back yet.    I could, of course, manually download states or degree tiles using the seamless server, but I want to do it programmatically so that users of my trip planner can get elevation data for their region without human intervention.  And SRTM isn't high enough resolution for bicycle/wheelchair trip planning.  Any ideas?

I'm looking for aerial LiDAR or terrestrial laser scanner data in laz or las format preferably from an FTP site.   Does anyone know which countries have that data available to the public?   From my research it doesn't seem to be easy to come by.
