![]() ![]() ![]() ![]() Stretched exhibits your reported bug and "Unique Values" just doesn't show anything. Use Classified - The Classified symbology method seems to display both NoData types properly (i.e.e as the same thing) so use that if possible and you don't want to alter the data. Some other tool may be able to re-render it while keeping the data as 32bit floats. Stack Exchange network consists of 182 Q&A communities including Stack Overflow. On the downside this converts it to 8 bit data (0-255). First time install and use for QGIS, running windows 7 In QGIS browser or through project>open I can not see any raster files/data, only vector data is shown. If you don't tick the use-renderer your new file will have the same issues. ![]() However, there are a couple of possible workarounds:Įxport the data - If you export the data being sure to "use renderer" it will start working correctly. The number of pixels identified depends on the size of your Pixel Inspector window. It is similar to the Identify tool however, it will display an array of pixel values instead of a single pixel value. I have absolutely no idea whats happening in the data (but my guess would be that there are two different "noData" values being used behind the scenes, one may be "null" the other "-9999" for instance) but would be interested to know, maybe someone else can enlighten us. The Pixel Inspector tool is used to view the pixel values of your raster dataset when displayed in ArcMap. You're right in that ArcGIS shows two different types of NoData even though the attributes both show the same thing. Thank you.There's definitely something very funky going on with that file/data. I am still learning how to use ArcGIS and could really use the help. If I'm not providing enough detail please* let me know. However, I only wanted to value column to join, not the objectID and count columns - and I have to figure out how to correctly join all 6 rasters (min elevation, max elevation, mean elevation, min slope, max slope, and mean slope). However, when I tried to join the slope/elevation raster attributes (also note that I only want to join the elevation/slope number from the elevation/slope attribute table) I got this: You'll notice that the last three columns on the right are the ones that I joined. You may want to use an existing raster catalog as a template if you have created additional fields in it that you want to have in your new raster catalog. Optionally, choose a template raster catalog on which to base your new raster catalog. If you load the raster catalog into ArcMap you can right click-> data-> export footprint, as a shape file or feature class. Then right click and load (if the rasters are just sitting in a folder then 'load from workspace'. I looked around online and on youtube and found that I could use the INT tool to create an attribute table for the elevation/slope rasters. Right-click a geodatabase and click New > Raster Catalog. In ArcCatalog you can create a raster catalog in a. It may or may not look different.in your case, there was a consistent transformation of coordinates so that would not alter the shape of the file, but differences in the location relative to the central meridian in their respective coordinates systems. PolyGeo at 3:13 I'm having the same issue. Can the raster dataset be opened and displayed in any other raster packages Maybe it is corrupt. Perhaps expand on your question by telling us what ArcGIS version and image format you are using. I attached a picture to show you - the attribute button is greyed out. Open a new data frame, move the projected file to it. 1 I'm assuming that you have tried Zoom to Make Visible from the layer context menu. However, when I try to join the slope/elevation data I can't because it looks like they don't have an attribute table. My thought was that I could then join that slope/elevation raster data into another raster. To be more specific, I created min, max, and mean slope/elevation raster data with the zonal statistics tool. I am working on an ArcGIS desktop project and am trying to join raster data that I created using the zonal statistics tool to a another raster. ![]()
