Using Python, how do I apply a unit conversion function chain to each individual raster based on source units? I'd like all units to be in Meters. I have a mosaic dataset containing elevation rasters with mixed source units: feet and meters. I'd like to : 1) iterate through the mosaic dataset, 2) check the units of each raster, 3) if the raster has source units feet, then apply a unit conversion function chain (ft to m). Rasters with source unit Meters do not need a function chain. Thanks!

I see. Pretty simple. Thanks!

Thanks. But, it is not always that simple... I want my code to fire only once. I have a couple callbacks when the event occurs. So... I need to wait until the callbacks are finished or, I was thinking, use the nifty on.once dojo functionality. I'm still not clear how to invoke it's magic. None of the following works: on.once(...); on(...).once(); handle.once();

If so, can someone provide example code? Thanks!

Some additional random info... Years ago, combining features into less features would help with performance. Maybe not so much these days... not sure. I'm just trying a couple things. Contours are for display only. These are two foot for the whole US. For the most part, being processed per county and stored in a FGDB per county. Served as one contour map service. The MXD has a lot of feature classes; one per county. This may present a problem at some point...?...? I have one county whereby the clip keeps crashing. I'm trying to clip off contours outside the county boundary whereby the DEMs overlapped across county lines somewhat. I thought maybe combining the features would also help with the clip operation. Cheers, Jerry

I have a contours feature class. It has many features. I'd like to make one feature so it draws faster. How can I do this via Python? Thanks!

How do I georeference an ASCII file into an ArcGIS JS Web API map? I know the extent and spatial reference. I'd like to render the symbology as a red to yellow to green color ramp. Thanks! // create and add the layer var mil = new MapImageLayer(); map.addLayer(mil); // create an add the actual image var mi = new MapImage({ 'extent': { 'xmin': -8864908, 'ymin': 3885443, 'xmax': -8762763, 'ymax': 3976997}, 'href': 'http://il.water.usgs.gov/_ags60fb0c9554ef42a58e7024d8464a2ecb.png' }); mil.addImage(mi);

https://community.esri.com/ideas/10513 How do I export an ASCII to PNG with symbology? I need to create a PNG with color ramp from an ASCII to be georeferenced in an ArcGIS JS web app. How do I do this? I was going to create a GP Service to create the PNG, but it appears I cannot do this with Python? What would be the alternative? ArcObjects C# GP Service? Thanks!

I have an ArcGIS Server installation. I want to host the 'generate' service with my ArcGIS Server instance so I am not relying on ArcGIS Online. Can I do this? If I cannot do this, are there any problems with continuing to use this service for free? Thanks!

Using arcpy, how do I identify the intersecting rasters within a mosaic dataset from a polygon? Thanks!

THANKS!

Thanks. I was messing around with the parameters. This is a mistake. I get the same error when adding {overlap_type}: arcpy.SelectLayerByLocation_management('sections_lyr', 'INTERSECT', row[1])

The fill is always black for me. The color property does not appear to change the color, i.e. STYLE_VERTICAL. Always black. Is this a known issue? Thanks!
