Extract Multi Values to Points Error: 000546

RussellNasrallah1 · ‎01-07-2019

Hello All,
I am trying to project raster elevations onto transects of points from 2-3 different DEMs which I will provide the details to below. The issue I'm having is I keep getting the following error:

I have tried removing DEMs until the tool will run and its effective only on the 20121011__clip.tif DEM.
Things I have tried:
I have attempted to reproject my point shapefile, and all 3 DEMS into the same XY coordinate systems, but I am still running into the same issue. This may be perhaps due to my shotty ArcGIS work causing me troubles I can't identify, but I've checked out all the obvious things I might be able to fix. I would love to get this tool to run with all 3 DEMs, but only the 20121011... DEM and the fmp... DEM.

Let me know if additional information is required!

checking the coordinate system is one thing, but... actually looking at each layer's properties to ensure that the extents make sense and actually overlap is more useful. If can identify cases where 'points' that appear to overlap on a map actually don't because one or more coordinate systems have been 'defined' and not 'projected.

Worth a check before you start Defining and Projecting without a plan

I'm not entirely certain what you mean by checking a coordinate system is 'defined' as well as 'projected'. I will try and look into this more!

Coordinate systems and projects are something I always struggle with when working with GIS data, so its no surprise that they're giving me trouble now.

Hi Russell,

Define Projection and Project gave me endless headaches when I started too! To further clarify, we "define" a projection when the spatial reference of a dataset is unknown or undefined (or sometimes if it's incorrect). You can tell if your data has an unknown or undefined because there's a warning that pops up when you add the data to a map telling you so. You can also tell by right-clicking on the dataset and looking at the properties. It'll say "Unknown" instead of having a spatial reference defined. Or if it's incorrect, your data will show up in the wrong place!

There's a tool for defining the spatial reference of a dataset called "Define Projection" or the spatial reference can be defined through the properties. Rasters are always a little different, so there's some documentation on how to handle them as well:

Define Projection—Help | ArcGIS Desktop

Defining or modifying a raster's coordinate system—Help | ArcGIS Desktop

Raster coordinate systems—Help | ArcGIS Desktop

If we want to actually change the spatial reference of a dataset (i.e. it already had a spatial reference, we just need to change it), we use the Project tool for shapefiles and feature classes and Project Raster tool for rasters:

Project—Help | ArcGIS Desktop

Project Raster—Help | ArcGIS Desktop

Here's a really great blog that goes through the difference between defining a projection and projecting:

ArcGIS Projections: Define Projection and Project

Hopefully that helps for this project and for future endeavors!

And then there is the visual guide

Hi Russell, what version of ArcGIS software are you using? Earlier there was a bug of this tool when multiple input dataset have different coordinate system. But from your description, you've tried re-project all data to same spatial reference.

Can you contact me at wying@esri.com to have detail discussion? It would be better that if you can provide the data,which will help for investigating.I want to help narrow down the issue and also offer work round if necessary.

Actually, we've re-engineered the tool in recent build, hopefully your problem is solved if is truly a bug.
