Data Format Requirement
Non-tiled OBJ Data Format (required)
- Export a single obj model and corresponding mtl material and texture files.
- Compress the obj model, mtl material files and relevant texture files into a zip file.
- Log in altizure.com, click Create -> Third-party Model ->Photogrammetric Model->Create, upload the
.zipfile package for conversion.
Q: What to do when the zip archive is too large to upload, or the conversion process prompts "zip file error"?
A: You can use the 7zip or other tools to perform volume compression. Divide a large compression package into files of about 200 Mbyte each and then upload all these files to the project.
Q: How to assign the geographical coordinates?
A: Adding a metadata.xml file to the archive file with coordinate information description. Usually the metadata file is placed at the root of the archive directory and its file format is as below.
<?xml version="1.0" encoding="utf-8"?> <ModelMetadata version="1"> <!--Spatial Reference System Only ENU coordinate system can be supported. The two numbers after the ENU are the latitude and precision of the ENU coordinate system origin.--> <SRS>ENU:22.64434,114.06046</SRS> <!--Origin in Spatial Reference System The origin coordinates of uploaded model in the ENU coordinate system.--> <SRSOrigin>0,0,0</SRSOrigin> </ModelMetadata>
