Hi

I used FLIR VUE PRO R with 3DR solo  
Unfortunately pictures do not have GPS information but it’s okay I don’t need geoinfo

I tried to mapping with Pix4d and got results like this

I want to get orthomosaic or index map with thermal information

I got some tif files but these files are black and white

Sorry I can not upload ‘tif’ file

What can i do for get orthomosaic or index map file with thermal information like tiff, RJPG…etc

Hi Kim,

Could you please upload one orthomosaic (tif, tfw and prj files) on our [OneDrive](https://pix4d365-my.sharepoint.com/:f:/g/personal/teodora_enache_pix4d_com/EhNqJrBqhXRKsw24klMfJs0BIa0Fn4w04S7_gBrLk6LuMA?e=cXrBqq)? I want to take a closer look.

Best,  
Teodora

Hi Kim,

These files (even DSM or any large tif file generated) will look black and white when you open with a windows viewer. They are floating point files that cannot be read by standard Image Viewers because they cannot interpret its values. You need to open it with QGIS/ArcGIS. The reflectance map and the index maps you get for thermal have temperature values in each pixel. QGIS is open source and free.
