My data isn't being downloaded as a zip folder, only as a .tif, any help on this matter?

[@joshuayoung1935]

so basically these DEM are available for U.S. only?

[@DonBoyes]

Yes, as they are provided by the U.S. Geological Survey. There may be similar services for other countries - for example there is one for Canada kzbin.info/www/bejne/mperf5qepq2Xjqs

@@DonBoyes How about Cambodia? Where Could I download DEM?

[@DonBoyes]

@@DK_4x4 I don't know have any experience working Cambodian DEMs, but I did a quick search online and found this video that might help: kzbin.info/www/bejne/gJOqYpxsiNGch5I

I watched this tutorial and I noticed that the File Format you used isn't available on the TNM. All that is available is a GEOTiff. I am able to bring it in to ArcMap, but it won't let me clip the tiff. Do I need to convert it into polygon first and then back to raster?

[@DonBoyes]

I find it's best to work with rasters in a geodatabase - instructions can be found hereL desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/importing-a-raster-dataset-into-a-geodatabase.htm

[@zuhrasrabony43]

Great! But how can I download DEM for Bangladesh :'(

[@uavabl1747]

Great

[@ronzaelias7909]

Can I use the same file in PCSWMM?

[@DonBoyes]

Sorry, I'm not familiar with PCSWMM but if it accepts standard file formats, then probably.

[@samfuchs314]

can't find any dem data.

TNM Download (v2.0) Doesn"t show me squat. No selection, now download cart. Nada. Crap, non-intuitive interface that says "Do a search" under products. Great! I've defined my area of interest with a bounding box, polygon...whatever. Nothing shows in the product tab. Useless.
