    <p>I am attempting to create a raster based on input from another raster. If a raster value is equal to a number included in a set() than I want it to be 1, else 0</p> <p>I've attempted the following:</p> <pre><code> ConfusedRaster = arcpy.Con(inraster in repeatSet, 1, 0) </code></pre> <p>and</p> <pre><code> ConfusedRaster = arcpy.Con(inraster, 1, 0, "inraster in repeatSet") </code></pre> <p>Neither of these work. I believe they don't work because the where clause only accepts Map Algebra expressions: <a href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z00000005000000.htm" rel="nofollow">ArcGIS Help</a></p> <p>There are two other ways I can think of doing this. One being converting it to a NumPyArray and working with that. The other is looping through the set and creating a raster object for each value in the set. After the loop has finished merge them.</p> <p>Does anyone have any suggestions or comments on how to go about this?</p> <p>Thank you</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
