How to convert XYZ data to multiple raster DEMs in batch mode using ERDAS IMAGINE 2015?

I've found tutorial: http://community.hexagongeospatial.com/t5/ERDAS-IMAGINE-Q-A/HOW-TO-convert-XYZ-data-to-multiple-rast...

but it is dedicated for version 2016. Unfortunately, when I used version 2015 and I open window Select Batch Files, format XYZ is unavailable (in both tabs: File and  Multiple File Selection).

Do You know any solution in ERDAS 2015?

Dear GODGIK_1,

Same solution works for IMAGINE 2015. If you can't see your XYZ files, place an asterisk (*) in File name row. Click Enter.

Then select XYZ files you want to process. 

The selection pattern on Multiple File Selection tab you need to specify manually (e.g. D:/*.xyz).

Thank You for reply @mvardovs

I have one more question:

How should I prepare batch file if I want to convert XYZ files (for example 1.xyz, 2.xyz, 3.xyz) to raster ( respectively convert_1.img, convert_2.img, convert_3.img) ?

Hello CODGIK_1,

In the batch file I've created there is a line for Output1 variable. $(Input1.pathright) $(Input1.root)_convert.img part will do the automatic naming for the output IMG file. If you have 1.xyz, so in an example provided the output IMG file will be 1_convert.img . If you want to change it to convert_1.img, so you should place "convert_" at the beginning. See below:

/*

** IMAGINE Version 16.0 Batch Commands File

*/

variable Input1 User;

variable Output1 Auto "d:/output/convert_$(Input1.root).img" Delete_Before;

dtmsplitprocess -single d:/input/test.dfp '$(Input1)' '$(Output1)' -even 1 1 -overlap 0 -meter 'DTM Split'

Note: I've removed $(Input1.pathright) here just in case if you would want to open XYZ files from different directories. (there is also an article for this issue Incorrect Output Paths)

Hello @mvardovs

Thanks for reply.

I have last question:

I prepare surface using Terrain Prep Tool. I add *.xyz file, next Process-->Surface-->Rasterization

I sign Output DEM, set cell size (1m) and I click Cancel button in the Surface DTM dialog.

I save Terrain Prep Tool project file (*.dfp).

I prepare Batch Command file (*.bcf):

/*
** IMAGINE Version 15.0 Batch Commands File
*/
variable Input1 User;
variable Output1 Auto "e:/temp/wynik/convert_$(Input1.root).img" Delete_Before;
dtmmergeprocess -single e:/temp/tptp.dfp '$(Input1)' '$(Output1)' -temp temp 0 -meter 'Terrain Processing'

I load the Batch Command File (*.bcf) in the Batch Command Editor.

ERDAS IMAGINE > File tab > Batch > Open Batch Command file.

I click the Add Files button to add all of the XYZ files to be processed.

I create a Batch List file(*.bls):

Input1 Output1

d:/temp2/test.xyz ""

d:/temp2/testv2014.xyz ""

I click the Run Now button to begin the batch process, but it does not work, what can be wrong?
