Hi @DanPatterson , I was hoping you could help me on this problem again. Using the Lowest Position tool, if one of the rasters has a cell with "No Data" it returns the output cell with no data. Is there a way for it to choose the lowest value available from the input rasters rather than the cell of the no data value?

Thank you that worked! 🙂 Is there a way of knowing which raster dataset was selected for the minimum used. I am having trouble with the classification for the symbology.

I am calculating the Newmark displacement (ground failure) for my local area. I calculate this in various percentiles (1, 10, 30, 50, 70, 90, and 99) creating multiple raster layers that overlap. Some cells will have multiple values because of the different percentiles. I am needing the minimum value within each cell out of the raster layers and to create a singer raster file if possible. Can someone help me with a tool or way to achieve this outcome? Thanks in advance!

Hello All, I have land cover data that I will be using in a landslide susceptibility map using logistic regression. The authors of the land cover data have already added pixel values for the different vegetation types. The susceptibility model that I am following has different coefficients for each type of vegetation. I am not sure how to specifically calculate for each vegetation type because there all within the Land Cover raster. I also have lithology data that I will be using as a proxy for rock strength and was wondering how I would go about adding that value to each pixel for its respective category. Any advice would be much appreciated.

Hi Dan, Just gave this a try and was able to convert to .tif ext but still ran into the issue with projecting the raster to WGS_1984_UTM_Zone_11N and getting the empty geometry error. So in the process of attempting a work around by setting my data frame to WGS_1984_UTM_Zone_11N and then Exporting the raster and saving it in that projection. I noticed the Extent changed from (-180.0000, 90.0000, 180.0000, -90.0000) to (nan, nan, nan, nan,), when I changed the spatial reference. I've attached screen shots if that helps. I am assuming this might be the reason I am running into this error. Any advice? Best, Toni

Hi Everyone, I downloaded the data for the Global Lithological Map (GLiM) Data base. I projected the raster in its native projection of Eckert IV (World) per Hartmann and Moosdorf, 2012; and I need to project the raster into WGS_1984_UTM_Zone_11N and also change the cell size to 250. I keep getting this error. I am not sure how to go about correcting this error. When I downloaded the data the file name has an extension glim_wgs84_0point5.txt.asc and I thought converting the ACSII to ESRI Grid would help but that didn't work. I tried repairing the geometry but the file isn't available for me to select. I am stuck and not sure what to do. Help me! Raster Data: http://dx.doi.org/10.1594/PANGAEA.78853
