TOPIC: ED50 D.E.M. - D.E.M. HEADER FORMAT

ED50 D.E.M. - D.E.M. HEADER FORMAT 10 years 5 months ago #29

Hi

Does RAMMS work with ED50 D.E.M.s?

and if so can the header of the ASCII file be as the following:

NCOLS 1001
NROWS 1001
CELLSIZE 2.000
XLLCENTER 390080.419
YLLCENTER 5088199.374
NODATA_VALUE -9999.000
3105.501 3107.261 3108.271 3110.361 3113.601 3115.201 3115.431 3115.021 3116.041 3116.351 3116.431 3117.101 3119.751 3122.311 3124.281 3127.121 3129.881 3132.191 3134.371 3136.691 3138.511 3140.101

?

If not may You suggest me the easiest way to convert the format shown above in a format readable for RAMMS?

Thanks for the interest You will show.

Dear Maurizio

In the manual (4.2.1, p. 25) you see the format supported by RAMMS. It's also important (at the moment) that the order of the header lines are as shown in the manual and below. We use

XLLCORNER and YLLCORNER

and NOT XLLCENTER and YLLCENTER !

I will do some work there for the next RAMMS update, in order that there are fewer problems with DEM formats.

Header of supported ESRI ASCII file:

NCOLS 680
NROWS 560
XLLCORNER 625501.25
YLLCORNER 108298.75
CELLSIZE 2.50000
NODATA_value -9999
2342.230 2341.110 2340.210 2338.910 2337.230 2334.940 2331.990 2328.650 2326.420 2324.410 2322.790 2320.170 2317.700 2315.200 240 1757.770 1755.160 1751.940 1747.480

Hope this helps.....greetings

Marc
