comment How to extract Z data from a point layer
I have never had an issue with this process. An alternative is to use GME (Geospatial Modeling Environment) spatialecology.com/gme and use the isectpntrst tool

comment How to create a TIN from UAV images or Google Earth images
No, the joining of images will only give you a mosaic (single image for visual...pretty picture). You need to have a software (PhotoSynth or SimActive) that can make a point cloud from multiple images). I suggest you continue looking online at options. There are some pages dedicated to this process. I have seen someone put up a full workflow using a SenseFly UAV.

comment How to use Google Maps projection with GeoDjango/PostGIS
Well that is no the purpose of the website. It was created as a reference, not a tool to answer specific questions related to technology or software products.

Check out spatialreferencing.org it has the projections and Moore information about them. It is a good resource to use

You may want to look at using EPSG:3857. This is a standard projection for webmaps. If you look at the projection of Google Maps from Open Layers (in QGIS), this is the projection that is used.

What settings did you is? What projection is the data in? I have had issues in the past with data in a geographic projection
