Blender addons to make the bridge between Blender and geographic data

Blender GIS

Blender minimum version required : v2.83

Note : Since 2022, the OpenTopography web service requires an API key. Please register to opentopography.org and request a key. This service is still free.

Wiki - FAQ - Quick start guide - Flowchart

Functionalities overview

GIS datafile import : Import in Blender most commons GIS data format : Shapefile vector, raster image, geotiff DEM, OpenStreetMap xml.

There are a lot of possibilities to create a 3D terrain from geographic data with BlenderGIS, check the Flowchart to have an overview.

Exemple : import vector contour lines, create faces by triangulation and put a topographic raster texture.

Grab geodata directly from the web : display dynamics web maps inside Blender 3d view, requests for OpenStreetMap data (buildings, roads ...), get true elevation data from the NASA SRTM mission.

And more : Manage georeferencing informations of a scene, compute a terrain mesh by Delaunay triangulation, drop objects on a terrain mesh, make terrain analysis using shader nodes, setup new cameras from geotagged photos, setup a camera to render with Blender a new georeferenced raster.

blendergis's Issues

Place the Georef Cam higher

Sometimes I get black holes when I render the image:

This happens when there is a single peak that is higher than surrounding terrain. Is it possible to have the camera higher by default, so it's above all parts of the DEM?

only connect verts with different heights in delaunay triangulation

Hi Domlysz,
At the moment, the Delaunay triangulation sometime gives plateaus were there shouldn't be one. It is due to the fact that verts of the same height are taken as candidates, even if edges are already present. Here is a blend showing the problem and what "bridge edge loops" does. Would it be possible to have an option 'ignore verts of the same height' or better, ignore them automatically when verts are in an edge?

[enhancement] Move selection (offset to georef)

Hi,
I've some files with objects allready georeferenced, and would like to be able to append them to current scene.

In such scenario, linked objects are imported with current scene origin offset added.
It could be usefull to offset selection from current scene georeference.
Maybe 2 small buttons (add and remove offset) could do the trick.

3/5 add-ons don't show up in Blender v2.69

Greetings,

I'm having some trouble installing BlenderGIS in Blender v2.69. The "Set reference cam" and "Import raster georeferenced with world file" add-ons appear and install just fine (see picture), but the other three add-ons in the BlenderGIS package (io_shapefile, terrain_analysis, and delaunay_voronoi) do not.

I looked at the "init.py" for the "io_shapefile" add-on, and nothing in the "# Register in File > Import menu" section looked drastically different from the same section in the working "io_import_georaster.py" script, so I can't identify the problem that prevents Blender from adding io_shapefile to the add-ons list.

The only thing I noticed that all the non-working add-ons have in common is that they are in folders with multiple scripts, whereas the working add-ons are standalone scripts.

Any insight would be most appreciated!

[feature] Import / export gps path for drones

Hi,
Currently working to implement io for gps based path to setup (dji phantom like) drones fly path (kml, kmz) right in blender.

Got a rougth implementation reading kmz (path only) from earth and kml export still needing some love (especially altitude as relative ones instead of absolutes - we do have to make some more tests).

The export has proven to be a pretty good basis to setup fly, and tracked movie resulting path show a realy small derivation in xy coords of 0.3m only (with a constant 3m +- 0.5 on z axis mostly due to setup error). So it's working like a charm.

Adding Mac OSX & Linux support in documentation

Hi Dominique,

I saw your great Wiki and the installation for gdal python bindings inside blender ont this page : https://github.com/domlysz/BlenderGIS/wiki/How-to-install-GDAL
It's very helpfull but there is windows only installation. I don't use Windows. According to you, I would want to add other plateform to your wiki.

Mac Osx
Tested on Yosemite 10.10 and Blender 2.74
1) Install Xcode and Macports from this link :
https://www.macports.org/install.php

2) Install gdal and gdal python bindings
Open a terminal from spotlight or from Applications => Utilities => Terminal
Then type with administratives rights :

sudo port install gdal py34-gdal

3) Copy osgeo folder from python bindings to blender

cp -rf /opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/osgeo /where_you_put_blender_on_your_mac/Blender/blender.app/Contents/Resources/2.74/scripts/modules/

Replace where_you_put_blender_on_your_mac with the path where you run or install Blender

Test it in Blender Python console like windows installation.

---

I think there is a mistake in the wiki with this :
Finally, to get GDAL working in Blender, just copy osgeo folder in Python tree folder of Blender (C:\Program Files\Blender Foundation\Blender\2.70\python\lib\site-packages).
If I put the osgeo folder in the same path like you recommand (python/lib/site-packages), I'm not able to launch gdal from blender. When I put osgeo in blender's module folder, It works !

Sorry for my poor english, I'm french ...

Sincerely,

Sylvain

export applies rotation and scale, modifying the .blend file

Hi Domlysz,
It would be better if the export code could let the scene as it is.

Off by half pixel when importing geo-referenced raster images

Hi,

Thanks for developing this add-on, it helped me a lot.

The issue is I think related that the export code of QGIS (and maybe other programs) specifies the world coordinates for the center of the corner pixels, not the corners of the image. It is particularly visible when importing images that should tile perfectly (and do tile perfectly when importing in QGIS), when importing them in Blender there is a small gap between each tile image.

importing OSM fails

Hi Domlysz,
"path to long for windows, overpass request failed" is printed in the console output.

Pyproj not defined when opening user preference dialog on windows 10

Hi,
When i do open the user prefs dialog to setup a CRS, i get the following error :

field selection options do not show up in Ubuntu 16.04 LTS when importing SHP file

Hi I have blender 2.77a installed on Ubuntu 16.04 along with your great add on. Unfortunately I have not been able to successfully use it on linux (although I have tried on Windows 7 and it worked fine). What Im getting when importing a SHP file is after checking the box next to either "Elevation from field", or "Extrusion from field", no dropdown appears with field options.

Thanks!

Add compatibility with dxf importer

https://wiki.blender.org/index.php/User:Cnd/Extensions:2.6/Py/Scripts/Import-Export/DXF_Importer

it use pyproj to convert coords on the fly
SRID info is stored in scene

Problem with instalation

When testing the instalation runing "from osgeo import gdal", i get this error (see image). Also when i try to enable the Add-ons "3D View: [bigs] Basemaps" & "Node Editor: [bigs] Terrain analysis" i get an error (also shown in image at the top).

I'm running 2.77 on windows 7

Thanks!

Add compatibility with Blender-geo

https://github.com/vvoovv/blender-geo

It use transverse Mercator projection (not UTM) with dynamically calculated central meridian to minimize distortions. The central meridian comes through the center of the imported area.

https://github.com/vvoovv/blender-geo/wiki/Georeferenced-Blender-Scene

proj4 string equivalent:

+a=6378137 +b=6378137 +proj=tmerc +lat_0=0 +lon_0=6 +k_0=1 +x_0=0 +y_0=0 +units=m
with lon_0 = central meridian (here 6°)

To get this compatibility reprojection capability is needed with consequences :

• more dependencies (pyproj, proj4, gdal ...)
• why reimplementing a complex task like reprojection through a Blender addon while dedicated software like QGIS can do it in a more efficient way ?
• need to store projection definition in scene (proj4 string or EPSG code)
• determine input projection from user or from data isn't always an easy task...

Cache Folder?

"Please define a valid cache folder path ... " when I try to use this. Serveral path I did enter but the message appears ever.

Bmesh does not exist before Blender 2.63

Hi, thanks for your great tool.

I was unable to use the 3D viewer with my default ubuntu packaged blender (v 2.62, for ubuntu 12.04 LTS) because you import bmesh, which is included from 2.63. My advice is:
a) in the readme (or wiki) add a compatibility issue and tell to use v>=2.63
or
b) fix it ;) (painfully?)

cheers

Consider importing 3D buildings

I have just imported an osm file and works great (love the filter per key type). However I thought buildings would be in 3D but they are "only" flat elements.

According to this OSM's wiki on 3D buildings, OSM offers some tags that are used to store information about buildings that could be used to generate 3D meshes instead of flat ones.

Amongst others, I find these ones could be interesting to be imported:

• building:levels (as there are many more buildings that have this information instead of this one building:height
• roof:shape (which can be flat, skillion, gabled, half-hipped, hipped, pyramidal, gambrel, mansard, dome, onion,round, saltbox )
• roof:orientation=along/across
• roof:direction=*

Additionally, these ones could be considered too:

• roof:height
• roof:angle

About compatibility with dxf export

Bonjour Dominique,

J'ai une question sur les exports, je souhaiterais exporter en dxf, ce qui est possible dans Blender d'origine (qui produit d'ailleurs un résultat très propre d'un DEM en TIN) mais je perds mon géoréférencement. Du coup, ma question porte sur "comment ça fonctionne" pour réexporter en conservant le géoréfrencement.

Si je me réfère à ça
if "Georef X" in scn and "Georef Y" in scn:
dx, dy = scn["Georef X"], scn["Georef Y"]
else:
dx, dy = (0, 0)
Le dx et dy correspond au centre de l'objet importé ou centre de la scene ? Je pense que c'est l'objet et du coup je pourrais exporter en DXF géoréférencé en déplaçant mon objet avant de l'exporter grâce à bpy.data.scenes['Scene']['Georef X'] et bpy.data.scenes['Scene']['Georef Y'] que j'ai pu récupéré dans la console python

Du coup un simple déplacement devrait suffir pour que ce soit efficace avec :
bpy.ops.transform.translate(value=dx, dy, 0)

J'ai testé dans la console python puis export et ouverture dans Draftsight, ça fonctionne. Il faut que je scripte tout ça maintenant. Serais-tu intéressé pour l'intégrer dans le projet BlenderGIS ?

Cdt,

Sylvain

Handle null values when getting object's names from field

I must say that this plugin is one of the best I've ever seen. What huge potential here, thank you for working so hard on it.

I have quite a few attributes in my shapefile (.dbf?) such as building names. Is there anyway to map them to each 3d item as well? If not perhaps this can be another enhancement opportunity to map attributes with to each Blender item created. Thanks again.

Saving blend file with GeoTIFF as plane and DEM "forgets" settings

I have an odd problem. I create a new blender project with a GeoTIFF DEM added as plane and then again as DEM. I add a geo-referenced camera and have everything setup to render a lovely hill-shaded image. If I render the image after saving project and without closing the project I get the expected output. If I save the project, close it and then re-open it I get a flat grey image without any of the relief. All the settings are saved as set.

Any suggestions as to what might be happening here? I have 91 tiles to render and would like to batch process them by setting up the .blend files and letting them run overnight instead of having to manually run each one.

This happens on both Windows 7 64bit and Linux Mint 18 64bit with the Blender GIS extension added. Other Blender projects created without using the extension reopen correctly. I have attached the Blender file that create the first image above: 8_3.zip

And the GeoTIFF: int_tiff.zip

Import orienteering maps (*.omap, *.xmap)

Suggestion: Elevation from Nasa SRTM

Hi,
The nasa with it's SRTM data is I think the best source of elevation data that is freely accessible. Would it be possible to download the right SRTM data for the zone we work on and use the greyscale data in the displace modifier?

Applying a rotation transformation to a Shapefile mesh can cause errors in the TIN

This quirk isn't a big deal, but it caught me out, so I thought I'd raise it as an issue...

After importing a Shapefile, if you rotate the mesh and apply the transformation before using the Delaunay triangulation utility, the TIN will have errors in it. For example:

TIN created by rotating Shapefile mesh without applying the rotation:

Constraint delaunay triangulation to inside

Hi,

Do someone know if there is a way to constraint delaunay trinagulation to inside of a polygon or point ? Or a way to clean the mesh after triangulation.

Georeferencing

Hello, sorry if my question sounds easy, but I'm new in this.

I am trying to use BlenderGIS to georefence a 3D model in Blender. I managed to install the addon, but i can't find any CRS in Geoscene preferences. I want to use Lambert-93 (EPSG:2154 with transformation : 1671, according to epsg.io). I tryed to type these different codes in the Query, but keyword searh doesn't seem to work ...

What can I do ?
Thank you

Import point shapefiles as objects and scale by attribute

Love this plugin! I'm wondering if it can import shapefiles that are scaled by size to a certain attribute? Right now all i can get is a set of vertices that i cannot seem to convert into objects (see image). Also see question here.

Handle missing values when extruding shapes

I'm processing a shapefile that has missing values for the variable I'm using to extrude shapes. The values were generated by the QGIS zonal statistics plugin which produces a value of all asterisks, in this case, e.g.:

Id         : 0D4F7142E65527B3E050A00A568A259B
Featcode   : 15014
mean       : ************************

The version of pyshp bundled here doesn't handle this properly. The latest version at (https://github.com/GeospatialPython/pyshp) returns a value of None in this case.

But this still causes BlenderGIS to error. It would be better to handle these explicitly in your code, e.g. by setting the value to 0 for if the field value is None.

The bundled version of the shapefile library is also two years old so this should be updated too.

[DEM import] add an option to just import raw data (pixels point cloud)

shape file are too small after import

Hi Domlysz,
When I import one of the files included in http://download.geofabrik.de/europe/germany/baden-wuerttemberg/freiburg-regbez-latest.shp.zip , although I added the epsg code you gave in the dxf thread in user prefs and I used it on import, it is too small (the whole region is smaller than the default cube). When I import the SHP after importing the DXF it works like a charm.
The console output:

Control roof orientation when extrude polygons

Problem importing raster DEM

I highly doubt this is a bug, but I hope somebody can give me guidance. When I attempt to import a 16-bit raster DEM in tif format, I get very unusual results. See graphic at this link:
http://www.sco.wisc.edu/images/stories/download/blender2.png

However, the DEM looks as expected in QGIS:
http://www.sco.wisc.edu/images/stories/download/qgis.png

The process I used in Blender after installing BlenderGIS: file... import... georeferenced raster... Mode as DEM. Did not apply on an existing mesh.

Any thoughts on where I am going wrong? The process to import a DEM seems very straightforward.

Extrusion always occurs along "local" z axis

As stated,when you set an attribute for "extrusion from field" while importing shapefile, extrusion always happens along the normal of the face (in a polygon). If your polygon has a non-horizontal base but you still want to just extrude it along the global z axis, you can't achieve the result

gdal and basemap make blender crash on windows 7 x64

With latest buildbot and Gdal installed as you say in the docs (really good quality doc, I hope more plugins devs would document their addon like you). But I get following error and crash: http://www.pasteall.org/69995
I took gdal 2.0.2 and had to update numpy to 1.10.4, just like in your doc also. Note that the crash also happened before updating Numpy, so it's not due to Numpy I guess.
The tests from gdal import ... all work correctly in the python console without error.

Zoom to mouse position breaks alignement of 3D data and basemap if not over (0,0,0)

When zooming in the viewport after aligning the 3D datas and the basemaps, the alignment is lost. It looks like the basemap is being zoomed to mouse position, but not the 3D view, which is zoomed toward 0,0,0. (even when zoom to mouse position is activated in the Blender's user prefs)
Zooming when the mouse is over 0,0,0 works great.

Improve shp importer performance

Currently shp importer is terribly slow with large or even intermediate dataset especially with extrusion and separate object options.

Test file submitted by BenRacicot :
pvd-shp.zip

Currently the code extensively use list comprehension with all dataset in memory. Using iterator/generator can help to not overloading memory.
http://gis.stackexchange.com/questions/148834/creating-a-really-large-shapefile-without-eating-all-the-virtual-memory
https://github.com/mlaloux/PyShp-as-Fiona--with-geo_interface-

However it doesn't seems to be the real limitation here, Python can handle very large dataset with decent performance while Blender's 3d view can really be slow down with too many object or large mesh.

Profiling the code show that separate objects performance drop down is caused by implicit scene updates calls through repetitive operators executions inside place obj function
more infos and possible workaround : http://blender.stackexchange.com/questions/7358/python-performance-with-blender-operators.
In our case we need to find an alternative to bpy.ops for setting objects origin to geometry

For extrusion, bmesh.ops.extrude_face_region is the most cumbersome operation, it seems more tricky to find a workaround here

Shapefile import not working

I'am trying to import shapefiles from this source: http://www.geoportalpraha.cz/cs/opendata/6F72EDDF-CAA4-4243-8776-7006CB0B2521#.WH3WFWeqSM8 and it simply does not work. It ends with error "Unable to read shapefile".

Also, I must run import from File > Import, when I press space and choose Import SHP, it end with error, probably it needs to have already some file selected.

Basemap is 1.477x to big?

Hi Domlysz,
First of all, your addon is really impressive and useful!
I tried to get the basemap align with the 3D DTM from maperitive. But somehow, there is a light scale difference. The 3D model from maperitive aligns perfectly with .osm datas downloaded from the overpass API of openstreetmap.
What I've tried so far to solve the problem:

• set blender to metric system
• Set the right CRS system for the location
  But even with those 2 options, the basemap is bigger. I tried to find the factor by scaling the OSM import and I found it to be around 1.477.
  Would it be possible to have the basemap have the real scale?

Moving images to the wiki repo

I would suggest to move images to the wiki repo:
[email protected]:domlysz/BlenderGIS.wiki.git

Each wiki forms a separate git repo. One can work with it like with a usual git repo.

To clone the wiki just execute:
git clone [email protected]:domlysz/BlenderGIS.wiki.git

Then move images to the wiki repo, commit and push them back

When I try to comment out lines 356 - 364, file is imported fine, but it probably breaks something else.

Also, I experienced Blender crashes on files imported from SHP, here is related bugreport:

https://developer.blender.org/T48239

Don't know, if it is related to SHP importer or not. These crashes occurs with or without commented lines in script, however.

UPDATE: Importer produces inccorect mesh for this (and similar) file. Instructed by Campbell Barton from BF I added mesh validation into script as temporary fix. Will make pull request for it. This does not solve original problem, however.

UPDATE 2: According to SHP spec on wiki (https://en.wikipedia.org/wiki/Shapefile#Shapefile_shape_format_.28.shp.29), M range values are optional but import script is expecting them in all cases. Will try to fix it.
