Upload raster SRTM tile fails with GDAL error. STEPS:

login to webgis as admin
create resource/raster layer http://mujigae400.nextgis.com/resource/0/create?cls=raster_layer
CRS = EPSG:3857
file is RGB .tif
Create resource fails with message: "Errors found during data validation on server. Correct error and try again. Error message: GDAL library was unable to open the file."

--> tried both .tif unzipped and zipped. See attachment n21_e110_1arc_v3_TIF.zip

Your raster has only 1 band, 3 or 4 are required (see. http://docs.nextgis.com/docs_ngweb/source/layers.html#raster-layer)

To get compatible raster you can create it in QGIS like follow:

Open raster in QGIS
Select render type "Singelband pseudocolor"
Save as selecting output mode "rendered image"

Also you can use NextGIS connect plugin: https://plugins.qgis.org/plugins/nextgis_connect/

Димитрий:

That worked.

I have created several raster resources for this project: http://mujigae400.nextgis.com/resource/1/display

Now I am trying to create a raster and getting the message: "Could not load file! Try again"

The file size is 1.01GB. Is there a size limit on file upload?

Here is the raster file on dropbox: https://www.dropbox.com/s/kve8iwi8xyzcx5a/SRTM_Guangxi_mosaic_IMAGE.tif?dl=0

Большое спасибо.

Yes, there is a limit. You can't upload files bigger than 500Mb on free plan

Maxim:

http://mujigae400.nextgis.com/resource/1/display

We are interested in developing the site above to automate:

user upload of CSV point file
perform operations (interpolation, raster calculation) to find inundation depth
display inundation results.

Does NextGIS also offer development services of this type?
