My two test shapefiles both have .prj files associated with them. One is simply geographic - GCS_WGS_1984 - and the other is WGS_1984_Web_Mercator_Auxiliary_Sphere (which matches the projection of my basemap).

My app allows a user to choose a shapefile from their computer to load on top of a pre-selected basemap - currently just an ArcGIS Online map service added as a ArcGISDynamicMapServiceLayer. I'm using a FeatureLayer to store the shapefile. What is the best way to determine if the shapefile is of the same spatial reference as the basemap? My goal is to send a message to the user when their shapefile projection doesn't match the basemap's projection to let them know that the layer will not be added to the map. I can't seem to retrieve the shapefile's spatial reference though when using the "getSpatialReference()" method, even after adding the FeatureLayer to the map. I have tried this with a shapefile that matches the basemap projection, and with a shapefile that doesn't match the basemap projection...the value of the FeatureLayer spatial reference is always null. The following code: map.getLayers().add(featureLayer); System.out.println("Map projection is now: " + map.getSpatialReference()); System.out.println("Layer projection is now: " + featureLayer.getSpatialReference()); System.out.println("Basemap projection is now: " + basemap.getSpatialReference()); ...just prints this output: Map projection is now: SpatialReference [mWKID=102100, mWKT=PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere"... Layer projection is now: null Basemap projection is now: SpatialReference [mWKID=102100, mWKT=PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere"... I'm just starting to learn the Java API so any help would be appreciated. I haven't found any good examples yet of how to deal with this situation.

I do like the idea of having separate tools for Goto and then Buffer, so I'll probably go with this idea. My problem is that I'd like to utilize the Goto XY tool that's in ArcMap in my web app, but haven't found a way of doing this yet. I do not have any code, because I hate to say...I'm not a coder and wouldn't even know where to begin to code this thing from scratch. Was hoping there was a tool I could take advantage of, or even a javascript widget I could call, or a python script...or anything that already exists that would make this easier. I mean, when other people are creating web apps, how are they inserting a Goto XY function? Don't want to reinvent the wheel here if there is something out of the box I should be using. Hi Marie, Do you have a source script or .exe for the GoToXY? If so, then use that to create a script tool and use the script tool in a model. Read up on it here and here. Barbara

Is there a way to utilize the Goto XY tool within a model/toolbox? I'm trying to create a web app that will allow the user to input/goto a coordinate and then create a buffer around that point. I simply cannot find a way to "Goto XY" in a model thus far...still looking tho...

Running Arc Desktop 10sp2. Seeing same (no) result when I run LOS manually between two points - when my data frame is projected. As soon as I turn the data frame back to GCS 1984 and run the LOS again the line appears! Very interesting...

Peter..thanks for the advice. We have since uninstalled Image Server and started using Mosaic Datasets, and have had no problems since.

‎12-20-2011

Not sure what to try next, but I've created a mosaic dataset in Arc 10 and loaded SID imagery. I've built it with and without overviews. I've built the footprints both normally and radiometrically, and THEN rebuild overviews. I've defined the nodata for this dataset and ended up corrupting it. Looking for ideas on how to get rid of the blasted white space around my imagery so that it's not blocking the imagery underneath...would like this to be a nice seamless dataset that I can serve up eventually. Any ideas?

Coming with no knowledge of the pixel values contained in JPGs, the trick I always use with my imagery is to set the black or white background pixel values (255 or 0 in some cases) to transparent thru the Symbology "Display Backgroup Value" properties. Goto Customize and add in the "Pixel Inspector" to see what the values of your border are. If they are NoData, then you can also set this to transparent thru the same properties above.

Does this exist? I've only found notes for installing/configuring the API on IIS...which is not translating nicely for me unfortunately...being the n00b that I am to web server setup.

Hey Eric - Let me take this a bit further and say that I only want to select the pixels within my AOI which is a very small subset of the original world wide dataset. I have a shapefile of the boundary that I'd love to use as input to a tool, but I have not yet found a tool that will take a polygon vector as input for a selection on raster pixels. Once I have my AOI pixels selected I would like to create a new raster, complete with the original values (not binary).

‎11-09-2011

Wow Patrick...that worked...Thanks! Now I wonder why a raster clip doesn't automagically do this for me? I don't know why I would ever want the attributes of the parent raster in my clip...especially when I go to change symbologies. Should I open this as a bug?

‎11-09-2011

I'm working with a large elevation raster (range of let's say 930m-2500m elevation), so I'm first clipping out my area of interest to a new raster. Upon examination of the new clipped raster the "High" "Low" values are representative of the clipped area (let's say 1300m-1500m), but when I go to set the Symbology to Classified the breaks are representative of the original dataset and not the clipped data. When I open the attribute table, I also see the entire range of the parent dataset represented, instead of just seeing records for the clipped raster. I've even recalcuated statistics for the clip, and it doesn't update the attribute table. How do I get an attribute table that only represents the clipped raster, and not the parent raster? Using ArcGIS 10 sp 2.

‎11-09-2011

Ok...this seems like it should be a very basic function to me...but I have a raster (DEM with elevation values) and I would like to select all the pixels with an elevation of 1500-1600 meters and show them as a different color, or even create a new raster with just those pixels. How can I do this without converting this to a vector first? Using Arc 10 sp2.

‎11-09-2011

Funny you should mention this...I am also having the same problem with most of my services. I reboot my server regularly and then have to manually restart EVERY map/image service I have created...except for the Cached world map services ESRI provides on the AGS installation media. I've looked at the Config files to see if there was any difference in the Startup sections, but there is not. At this point, I really wish there was a batch "start all services" tool within Catalog that I could run, but I haven't found that yet either. Running AGS 10 on a Windows 2003 Server.

‎09-21-2011

Well I tried going in and changing all of the Image Server services to run as our domain SOC account, as this is the account we created for Server administration so that it could see the data on our share drive, but the Image services will not start up using this account...they will only start using the Local account. Server logs aren't showing any errors at all...Image Server log just says the same thing the error says...
