Tom - According to the "How Raster Calculator works", the tool is designed for single-line algebraic expressions.  The old 9.3 "Multi-Output Map Algebra" GP tool would do the syntax (somewhat) that you're looking for.  You can implement the multi-line expression within a Python Window if you wish, but here's the syntax I used in the Raster Calculator to get the desired output. OutRas= Raster("Viewshed") + (Raster("Elevation") * 2) Define your output raster and you've got output. Hope this helps! Regards, Robert LeClair Esri-Denver ... View more

Roland - I would consider using a Mosaic Dataset to reference your original raster datasets.  You can order the Mosaic to control overlap so as to avoid the black pixels you're seeing.  To learn more about MD - please visit http://resources.arcgis.com/en/help/main/10.1/index.html#//009t00000037000000 Good luck!

Wade (et. al.), Following up on this older thread, did you receive any insight on how to accomplish a balanced cut/fill workflow.  I have a student interested in this workflow.  Please advise. Thx, Robert LeClair Esri-Denver ... View more

Allen, One way is to go to http://www.arcgis.com and towards the bottom click the "Map" hyperlink to the right of "Maps for Personal Use" Good luck! Robert LeClair Esri-Denver ... View more

Hi Cassie - This is more an issue with the shapefile itself.  Please refer to the following doc for resolution - http://support.esri.com/en/knowledgebase/techarticles/detail/39474 Hope this helps! Robert LeClair Esri-Denver ... View more

First, you would have to have ArcInfo Workstation installed on your PC.  Then you would need to start the Arc program at Start -> ArcInfo Workstation -> Arc.  This will start the "old" command line environment that I "cut" my teeth on back in 1992. From the help doc: converts a set of ARC/INFO coverages into a set of U.S. Bureau of Census TIGER/Line files. ARCTIGER <out_tiger_file_prefix> <in_arc_cover> {in_point_cover} {in_landmark_cover} Arguments <out_tiger_file_prefix> - the file name prefix for files to be written.  File names will include the prefix concatenated with the record type identifier.  The file prefix may include a directory pathname. <in_line_cover> - the name of the input line coverage containing all the basic line features and attribute data. {in_point_cover} - the coverage containing the point features  representing polygon label points for <in_line_coverage>.  The same input coverage may be specified for both <in_line_cover> and {in_point_cover} arguments. {in_landmark_cover} - the coverage containing the landmark point features. Notes ARCTIGER is intended to be used in conjunction with the TIGERARC command and expects the input coverages to have coordinates expressed in degrees and decimal fractions of a degree of latitude and longitude.  Each INFO data file must have the same items and item definitions generated by the TIGERARC command. The <in_line_cover> and <in_line_cover>.ACODE are the minimum input and files type 1 and 2 are the minimum output generated by the ARCTIGER command. Up to 10 output files will be created depending on the input coverages and the associated data files used in the conversion. A File type 3 is not created by ARCTIGER.  Attributes from INFO data file <in_line_cover>.TYPE3 will not be used in the conversion. Good luck! Robert ... View more

There is a command in ArcInfo Workstation called arctiger that will convert an ArcInfo coverage to a TIGER file.  It requires an ArcInfo license to work though.  If you have the license, then you could export the shapefile to a coverage, then use Arc Command Line to run the arctiger command. Hope this helps! Robert LeClair Esri-Denver ... View more

Zoe - It sounds like NIM068712.  To resolve this, create an unmanaged raster catalog and then export the raster catalog to a new raster. Good luck! Robert LeClair Esri-Denver ... View more

Yes, this is the default behavior... ... View more

It can come into play if you check the Unsplit Lines parameter in the DISSOVLE GP tool.  By doing so, lines are only dissolved when two lines have an end vertex in common. Regards, Robert LeClair Esri-Denver ... View more
