[OSGeo-Discuss] Crowdfunding campaign to add native support for Vector Tiles in QGIS

[Saber Razmjooei]

Hi all,

We have started a crowdfunding campaign to add native support for vector
tiles in QGIS:
https://www.lutraconsulting.co.uk/crowdfunding/vectortile-qgis/

For more technical details, see:
https://github.com/qgis/QGIS-Enhancement-Proposals/issues/162

If we exceed the goal of our campaign, we will also like to add creation of
tiles directly in QGIS.

Please help spread the word or funding the campaign.

Kind regards
Saber

Re: [OSGeo-Discuss] TIN file formats

Hi Pierre,

Apologies for the late response.

The link was updated. If your TIN is small, you can use MDAL to read it. An
example of such data (ESRI ADF TIN) can be found here:
https://github.com/lutraconsulting/MDAL/blob/master/mdal/frmts/mdal_esri_tin.cpp

With MDAL/QGIS, you can also display vectoral data (e.g. slope direction in
http://files.carlsonsw.com/mirror/manuals/Carlson_2014/source/Site_Road_Design/Surface/Triangulate_amp_Contour/08tri_contour9.PNG
).

Hope this helps.

Kind regards
Saber

Hi Pierre,
Very interesting! We are trying to create a generic TIN reader/writer for
open source applications:
https://github.com/lutraconsulting/MDAL/

MDAL already supports a number of TIN/mesh formats and it is integrated
with QGIS.

It would be good to join efforts.

Kind regards,
Saber
