[Released] GIS Terrain Loader

Powerful GIS Tools for Unity Engine​

GIS Terrain Loader is Runtime-Editor plugin that gives you the ability to import geographic data directly into Unity Engine, designed to load not only Real World Terrains data but also any supported customized terrain data exported from any GIS applications or external terrain generators (GlobalMapper, QGIS ,WorldMachin, ArcGIS ,SAS.Planet..etc).

GIS Terrain Loader create terrains basing on loading (Raster-Vector-DEM) data that makes importing and modifying large quantities of data fast and easy.

With GIS Terrain Loader you can:

- Import Digital Terrain Model (DTM) data to create accurate Landscapes.

- Import GIS vector lines to create 3D objects like a roads, buildings, trees and more...

- Import Raster (Textures) data to add texture to Unity terrains.


GIS Terrain Loader Support :

Current version v2.3

 

Can the loaded terrain be edit by Unity's Terrain Tools?

 

Hi July

Yes, Once terrain is generated it can be edited by Unity, this tools work with new terrain system.

For more Info please watch the video tutorial .

 

I purchased!

It seems can't run in 2019.2.

So I watched your video and run in 2018.3, but I got problems.

I can't generate terrain like video with your asset and my own.

The terrain seems to be very large, I can't see them all.

Do you have tutorial documents? I want to know how to set the parameters

 

I got Terrain Dimentions like this with your desert asset

 

we will soon update the asset to work with unity 2019.
we are testing the asset on the same unity version that you are using we hope fixing that soon .

 

Probleme solved please read your inbox.

 

GIS Terrain Loader Updated to v1.2 :

- Added support for Unity 2019.1 and Unity 2019.2
- Fixing some bugs happening with Unity 2018.3.
- Editor GUI improved.
- New : Added the ability to smooth Terrain surface and Terrain Heighs
this option used on hight heightmap resolutions .

 

when can I get this updated package? The ability to smooth Terrain is useful!

 

Package is on reviewing by unity asset store.

Yes ,if you try to load terrain with heightmap resolution > loaded file resolution you will have result as its shown on the first picture (top/ left)
using smoothe operation help to have clean terrain surface without box shape appearing.

 

GIS Terrain Loader Updated to v1.3

- Added support for OSM Vector Data (Tree + Grass).

 

Hi, i am interested in purchasing, however, its hard to tell if it does some features that i'm wanting so maybe you could answer before I buy.

So just to clarify, does the current asset (on the asset store) do the following?

Load terrain elevation and textures at runtime?

Is it 1 texture per terrain or 4?

Can you also elaborate on the OSM vector data for trees.

Lastly can you advise on any alternative software from Global Mapper than can export FLT and imagery that isn't $549!

Thanks

 

Hi there

This asset work on editor and at runtime.

At runtime you can load terrains and textures from your hard disk.

By using globalmapper you will be able to split your large texture into small tiles (4x4 - 5×8 16x16...etc).

GIS terrain Loader detect the number of tiles in texture folder and split your large terrain in to small unity terrain.


By exporting OSM data file and past it into VectorData folder GIS Terrain Loader will be able to generate Grass and trees, (we are working to add this option to runtime ).

You can use any prefab for grass and trees, Package already contain some prefabs.

This asset designed to use any software able to export texture and DTM files as FLT format.
Globalmapper is the best to use this asset.
But we can add support for other extensions like ASCII or RAW files if we are in need of that.

Thanks

 

My big

Thank you, I think this is great and a near perfect solution for my project. My only is issue managing to actually get a hold of the imagery and elevation data in a organised format without having to buy software for £500+. You see I want my users to be able to add their own terrains to my project, so not everyone (including me) will want to spend £500+ on gloabalmapper. Is there any other solution, I have tried looking for other softwares that export FLT and there doesnt seem to be many?

Plus, if different user acquire data from different softwares how is it organised when loaded into your asset. As in, how does the GIS Terrain Loader know the location of the data?

Thanks
Andy

 

Hi againe

Please watch tutorial videos to understand how this asset works.

GIS terrain Loader is an integration offline tools so he could not download data from online sources.
He is developped after many requesting of GloablMapper " saying : how to export terrains from Globalmapper to Unity Engine (Editor and Runtime) "

Globalmapper has a lot of data sources including premium data.

You can use GlobalMapper for 30 days to test how it works.

Thats a good idea may be we will include online sources for GIS Terrain Loader in the future.

 

Ahh ok, so this asset is suited mainly for globalmapper?

I would purchase your asset if i had globalmapper or other software that could output the FLT files.

I will have to do some more research.

Thanks

 

Let us more time

Let us more time maybe GIS Terrain Loader will support more DTM files like (ASCI,bt,raw...etc).

 

Ok thank you, look forward to it.

 

Some users ask if GIS Terrain Loader can load terrains from free GIS software because Globalmapper is expensive.

So we would tell all users that GIS terrain Loader will soon load terrains from QGIS.

QGIS is free software.

 

New Update v1.4 For GIS Terrain Loader :

- GIS Terrain Loader can load terrains from (QGIS && SAS.Planet).

- Added support for Terragen files ("*.Ter") and GeoTiff files ("*.Tif").

- OSM Vector loader added to Runtime GIS Terrain Loader.

 

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

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:

Code (CSharp):

1. Couldn't convert Terrain file:
2. UnityEngine.Debug:Log(Object)
3. GISTech.GISTerrainLoader.ProjectionReader:LoadJsonData() (at Assets/GIS Tech/GIS Terrain Loader/Scripts/GISTerrainLoaderRuntime/GISTerrainLoaderGeoRef/GeoRefConversion.cs:406)

(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

 

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".

I'm thinking of buying GIS Terrain Loader plugin. I know that it can generate roads from OSM data. Will the plugin generate buildings from OSM data?

 

Hi there,

GTL actually generate roads,Grass and trees from OSM Vector data.

we are working on it, GIS terrain loader 2.0 will also support building.

 

I'm not sure if I buy the plugin now or wait for V2.0. I was not happy with another plugin that generates roads and buildings from OSM data.

 

Hi there, if you only need buildings and roads you can use another.
Just Take your time to think about needs of your project and which asset that will realy help you.

As the 2.0 not released yet, you can give me some idea about what do you want exactly in your project maybe i can customize a part of the GTL asset for you. (New version need at least 10 days)

 

I wish to create a driving game in a city. Think GTA. The other plugin is very slow in generating buildings, roads, and terrains. I tried generating in groups of 4X4 terrains but the edges of terrains in one group don't match those in another group.

 

Hi there
Take a look on BuildR Procedural Building Generator asset.

 

I don't have $150 for BuildR Procedural Building Generator asset.

 

I would like to ask, why is this and where is the problem
