HI, I purchased the latest version of GIS Terrain Loader. i’m working with QGIS + SAS and followed the tutorial on how to generate the texture file tiles, DEM and preview file. I’m missing the process for generating the terrain in Unity as i dont have an .flt file. if i generate the terrain from the DEM through the Terrain loader it doesnt read the texture tiles…
how do i load into unity?
Hello
thanks for purchasing GIS terrain Loader.
To solve your problem you must select texture source (on GIS TL GUI)… from (globalmapper or from SAS.planet).
If you are using QGIS or youd ont have .flt you can use .TIFF as DEM file.
Please check your demo scene and your example files to see how files must be ordred.
We hope this will be helpful, if you find any issues recontact us.
worked 
thanks!
If you find it useful please rate and review in unity asset store.
You can request at any time for more features.

Hello,
I purchased GIS Terrain Loader and I have a few questions :
- Is it possible tu use an other elevation data source than SRTM30 Data ? I work on a SIG project and we have our own LiDAR data that i would like to use rather than SRTM30
- Is it possible to use a different coordinate system ? My SIG project is using EPSG:2154 Lambert93 … do I have to translate all the data in EPSG:4326 WGS84 or is it a way to run GIS Loader with Lambert93 datas ?
- Is there a terrain dimension limit ?
- Is there a resolution limit ?
Thanks for your work
Hi there
Thanks for purchasing GTL
1- for Lidar files please send to me a link of your elevation file we will try to add support for it.
2- let me know which GIS application are you using.
3- actually GTL support Geographic coordinates system maybe we can add support for lambert 93.
4-terrian dimensions limited by the amount of data are you using. Huge terrain consume more memory. To solve that we must add terrain streaming system ( in the future version) .
5- you can use terrain terrain resolution t x4096
GIS Terrain Loader Updated to v1.6
Released date : Jun 15, 2020
Updates :
/////////// DEM Support ///////////////////////////////////////////////////////////

- GIS Terrain Loader can load DEM Files type of (Las and Tiff) projected in (UTM and Lembert) than re-project them to Geographic(Lat/Lon).
/////////// General changes ////////////////////////////////////////////////////////
- New GUI Style for Editor tools.
- TextureSource Removed and Replaced by auto-Source Detection via Json File contains sources formats located in Resources folder.
- Terrains dimension can now loaded automatically or set manually for all DEM files.

Lidar To Unity Tutorial
Hi, using your included terrain DEM assets (e.g., Assets/GIS Tech/GIS Terrain Loader/Resources/GIS Terrains/SAS.Planet/Island/Island.tif) as well as arbitrary DEMs generated in QGIS as Uint16 GeoTiffs (per your great tutorial video), I get the following errors, from a clean install of your package into Unity 2019.3.15, running the Runtime Demo Scene:
Couldn't convert Terrain file:
UnityEngine.Debug:Log(Object)

(and then several more subsequent errors as the GeoTiff loader c# tries to continue).
edit2: the editor script produces precisely the same error (when trying to load the included terrain file Assets/GIS Tech/GIS Terrain Loader/Resources/GIS Terrains/Globalmapper/TIFF/Tiff_Int16Bit/Geographic(LatLon)/TIFF.tif), ruling out the runtime demo question.
Is this problem from:
- using 2019.3
- using the example GeoTiffs
- using the runtime demo on the example tif
- something else I’m missing?
Thanks for rapidly expanding this asset’s input filetypes list recently!
Ops
Sorry if that errors happen in unity 2019.3.5.
GTL not tested yet on that version but it works well in unity 2018, 2019.1 and 2019.2 .
Thanks for trying GTL on unity 2019.3.
Please let me test it on that version to know the source of that errors.
Best regards
Hi LoganPark
We tested the asset on Unity 2019.4.15.1f and 2019.3.15 it works well without any issues (generating terrains in editor or runtime).
Please tel me more about your system (windows-OS).
Try to use another unity version if its possible.
Check if unity has permission to read files from external sources.
Can you tell me why the TIF file I loaded can’t display normally
![6198034–679990–ZS)$U4{]D%14XRI7QZ3R.png|541x365
I have some problems with this asset. Lots of errors are still showing. I tried may times but still not working. Help me please!
Morning
Sorry if that errors happend, GTL not tested yet Unity 2019.4.
Give me some time to update the asset and fix all errors with your unity that versions.
Issues source :
scripts located on that folder " Scripts\GISTerrainLoaderRuntime\GISTerrainLoaderImageEffects"
1 - Maybe scriptes not working with unity 2019.4
2- it seems that you already have those scripts in your StandaAsset Folder
Quick Solution :
Try to delete effect folders that already in your project
Assets/NatureStarterKit/Standard Assets/Effects/ImageEffects/Scriptes;
or Delete GTL effect scriptes in :
" Scripts\GISTerrainLoaderRuntime\GISTerrainLoaderImageEffects"
i hope this can solve your problem
best regards
I solved it
Where was your issue?
Hi again GTL tested in Unity 2019.4.7, it works without any problem so :
Try to delete effect folders that already in your project
Assets/NatureStarterKit/Standard Assets/Effects/ImageEffects/Scriptes;
or Delete GTL effect scriptes in :
" Scripts\GISTerrainLoaderRuntime\GISTerrainLoaderImageEffects".
