ArcGIS Help claims that it is possible to perform multi-line statements in the raster calculator but I have not been able to do so http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Building_complex_statements/00p60000000p000000/ I'm wondering if this is a case of false advertising or if I'm missing something? My multi-line statement is relatively simple although I'm planning on eventually making it more complicated t1 = Raster(r"forest.tif") t2 = Raster(r"forest.tif") * 2 t1 + t2 -Tom Dilts ... View more

A tool that could create evenly spaced points and/or perpendicular lines would be useful.  This is something that I'd guess 90% of GIS users would use at some point or another. ... View more

My models with map algebra no longer appear to work in v10.  Is there an easy way to migrate them?  Re-writing them from scratch is going to consume a lot ot time.  Is there some sort of syntax like SOMA(.....) that I can use to make it realize that it is in map algebra syntax rather than python? ...

I recently got error 010067 when running a model in model builder (MB).  I enabled background geoprocessing in MB and the tool worked.  I also tried running the tool from ArcToolbox both in the foreground and the background.  The background worked and foreground didn't.  Has anyone else experienced such this strange behavior?  Any thoughts on how to fix things? ...

I've got a hydrology web service that I'm using in a web application (ArcGIS server).  The labels look terrible in my web application but fine elsewhere.  They appear as if they have some sort black background and they look kind of bold.  I'm wondering what is going on.  This problem is most evident with time new roman font with italics.  Is this some sort of anti-aliasing problem? ...

The spatial statistics toolbox could be improved by adding logistic regression and possibly other types of regression (such as autoregressive models for incorporating autocorrelation).  The OLS and logistic regression tools could also be improved if they were allowed to sample from a raster, run the regression, and then automatically generate a map algebra statement to create predictive maps using raster data.  Raster data tends to be more useful for many people in the natural resources fields, biology, and geology because natural phenomenon tend to vary continuously while people in the social sciences tend to be served by socio-economic data that is collected at the point level or summarized into discrete polygons.  The spatial statistics toolbox therefore caters to social scientists but expanding it to rasters would help accomodate the needs of a larger community. ...

Make the summary statistics geoprocessing tool easier to use.  If I've got one hundred fields that I want summarized I currently have to go in and add each one individually and specify the summary statistic to use.  This is too onerous so I tend to export my tables to excel for this step.  Other geoprocessing tools have the ability to add/remove all fields.  I'd also like to have the ability to highlight a block of fields and set their summary statistic automatically for all of the highlighted fields. ...

Hi all, My mosaic dataset created on computer A will not display on computer B because the drives are mapped differently.  Is there a way that I can re-direct it after the fact or do I have to start over?  In hindsight I realize that I should have mapped as UNC, but hindsight is always 20/20, right? ...
