Error 010092: Invalid output extent

[JW6]

Hello,

I am trying to create a Kernel Density estimation map to turn several data points into smooth colors.  This is my first attempt at
creating this kind of advanced map, and I'm running into some issues.

My underlying data consists of Latitude and Longitude points, which I have displayed correctly by converting to XY data using
GCS_WGS_1984 as the coordinate system.  However, whenever I try to convert that XY data using the Kernel Density tool, I always get ERROR 010092: Invalid output extent.

I've tried the default values, lots of other numbers as the output value, and I specified the coordinate system in the Environment
section.  As I mentioned, this is my first try doing this type of map, so I have a feeling the fix is something easy that I'm just not
seeing.  I did test this using an existing layer I have (Cities), and it worked with no issues, even with the default output value.


Any and all guidance will be more than appreciated!!!

Kernel density depends on area and distance, which are not appropriately measured in geographic coordinates. The first thing you should do at this point is project your points into a new coordinate system that will reasonably preserve both area and distance.

If you start by projecting your data, it's possible your other problems will solve themselves.

Thanks for the response!

Do you have any resources for projecting Lat/Long into another coordinate system?  As I said, I'm a total novice at this, and I'm not entirely sure where to begin.

You can project on the fly by changing the output coordinate system by pushing the  Environments button in any tool dialog -- but with raster tools it often makes sense to just project the inputs first to make it easier.

I found the answer - turns out I had too much data in my file.

I created a CSV with ONLY Lat/Long points, KDE worked fine.  Now I just need to fiddle with the resolution, and I should be golden.


Thanks for all your help!

This suggestion fixed the issues I was having with the tool. My input point field had A LOT of fields. I removed all but the value that was used as the Z input and it worked.

The issue I was having is the tool would run for part of the spline distance and stop. It was not a cell x cell count issue. 

Thanks!

Greetings All,

I can't say that I am having the same luck.

Starting with the GCS_WGS_1984 is what my X, Y coordinates are in.

I need a step by step follow up in (if possible) how to do a transformation here. I am struggling on what what to put in my output coordinates.

I have selected Output coordinate system as specified below. I just do not know what to select from that point on.

I have experimented with a variety of options, but I cannot seem to get it to work. I keep getting the same error above.

Cheers,

J

Here is the help with an example here:

Display these points as XY events, use the Project tool to project the points the same coordinate system as your raster, and all should be golden.

Raster processing is generally much easier if you have everything in the same coordinate system - extents don't easily project on the fly as features. You can   project on the fly, but you have to be very careful with the geoprocessing settings for Output coordinate system and extent. It's often easier just to project the data first.

I think you may have misunderstood my question. I have no problem displaying the data in X, Y coordinates on the map. I just have no clue how to get these points to work with Density Kernel. I was told it was because they were in geo coordinates and they needed to be in projections.
