The issue is that the global data is at too low a resolution (x, y pixel size). Either work with a different data set, or reprocess your data. Reprocessing will not improve data accuracy - this is limited by the source, but you can improve the visual display of the data. Convert your data from raster to point, and then use Interpolation tools (ie: kriging or idw) to create a new raster, but set the cell size to a much smaller value. The interpolation will smooth the transition between the points. You can also set the display of the resulting raster to "bilinear interpolation" to smooth it further. Best Regards, Jim ...

The -1 value is due to a null value. Check the data and insure that all entries hold a valid value in the field being used to designate the line. Best Regards, Jim ... View more

What is your "fixed" goal? To delete the records without points? to add geometry to the records without points, so they can be posted on a map, or something else? Regards, Jim ... View more

Symbol rotation IS indeed available in the Basic level license, regardless of the functionality matrix. Basic license is what I am working with, and I have the ability to rotate symbols based on a field. Something else is impacting the rotation of your data. Regards, Jim ... View more

symbol rotation based on a field is supported in the basic license. I am uncertain what you mean by "arithmetic" - are you calculating the rotation? This may be the issue. Regards, Jim ... View more

Looking at the Census Tract polygon data, and the spreadsheet from USDA, You should perform a join based on attributes using the FIPS column of the Census Tract data, and the CensusTract column of the spreadsheet. At this point, the spreadsheet data is associated with the polygon data, and can be used for symbology or analysis. Best Regards, Jim ... View more

Thanks, Robert. It is helpful to know I have not overlooked the obvious.... Again. Best Regards, Jim ... View more

It is possible that there is a problem with the geometry of the polygon layer. Run Data Management Tools >> Features >> Repair Geometry, and see if that eliminates this issue. Best Regards, Jim ... View more

Apologies for being vague. Perhaps the screenshot will help - I did not change from RGB. I changed the "Display Background Value" entry only. Regards, Jim [ATTACH=CONFIG]31734[/ATTACH] ... View more

For best results, you should set the extent to clip the rasters as close as possible to the edge of the data, then under the symbology tab for the layer, set the background color (these are RGB) to R = 255 G=255 B=255 and use the color = null (the default). I suggest altering the extent, because it appears there is a black line framing the white border. ... View more

No misunderstanding. I wasn't aware you were working with multiple types. Could you cluster by groves? Otherwise, it seems that you will have to divide by hand and visual interpretation. Or am I missing something that allows you to determine tree type / crown radius in an automated fashion? Regards, Jim ... View more

Perhaps convert the polygons to raster, with the cellsize set to your normal circle radius. Convert this from raster to points, and you have points inside the polygon representing each tree crown. Best Regards, Jim ... View more

Kurt, simply turn off the drop shadow under the frame properties. Regards, Jim ... View more

You are trying to contour 30m data at 2m intervals. This is a bad idea. You are trying to extract data / information that is not there. That said, you could add a field and calculate the length of each line, and then set a definition query that removes lines below a reasonable length. Regards, Jim ... View more
