Resolved this now. After trying different isolation, it turns out that the file format ECW is the culprit. I suspect our ArcMap version is too old to catch up with the ECW format. I used JPG and did not work. Had to use GeoTIFF images to create the mosaic and publish the WMS. This resolved this. Thanks everyone who has responded.

Where do you work and what is your role? Hi, I'm Thiru (aka Thirumurugan, if you want a long, Tamil name!), currently working as a GIS Consultant contracting for a local government authority in sunny Queensland, Australia. My current role involves publishing web services and administering ArcSDE to deliver optimal performance to Staff and Public. What GIS success have you had this year and what product did you use? My big success so far this year has been migrating our weed mapping staff to use AGOL on iPads so they can finish their mapping workflow digitally. Last year, they have been meddling with paper maps, notepads and calling / traveling to Office to check maps on the Desktop. Many more teams lined up to convert their workflows using AGOL and ArcGIS Desktop 🙂 What is your expertise (GIS related or not), and how can that help the community? My expertise is Writing to reach masses through blog posts. I guess I would be sharing my tips and tricks with you all (and expect to learn from your posts too!). Favourite Location -37.871829, 175.682564 (alright, alright, My favourite place on Earth is the Hobbiton village (Lord of the Rings movie set), New Zealand. Haven't visited but would love to.

Thanks Jonathan. Checked the overviews folder permissions. Looks good. Checked the arcgiscache folder where the tile cache are stored. Looks good. Here is the link to the 2017 map service which display checkered boxes at scale larger than 1:6770 ArcGIS JavaScript API: ImageryBaseMapsEarthCover/AerialMap_2017_SCC Here is the link to the Street Base Map service that has cache from the location.

The air photo supplier said none of the other customers had any issue in publishing the ECW air photos.

Thanks Jayanta. I am trying with JPEG2000 format (as we speak) to rule out the file format issue. I published another service with ECW just yesterday and it was good. I have contacted the air photo data supplier to see if there are any errors/issues related to this particular data set.

thanks for the write-up.

I am trying to publish a mosaic dataset containing air photo / imagery tiles in ECW format as a WMS. The WMS appears fine at smaller scales (regional scale), but it fails to show air photo tiles at larger scales (street level). At larger scales, only black and white checkered boxes fill the screen. The mosaic dataset looks fine at all scales in ArcMap. Analysed the mosaic and no errors or warnings. It appears that the overviews are not generating well (see the attached images). At street level, when I use "i" tool on the mosaic, I get only image no "Ov_xxx_xxxxx.ti" as I get at regional levels. I have done different iterations to eliminate the variables that might contribute to the issue. The ECW format is same as the previous year, I created the mosaic data set for 2016 and 2015 air photos and they are working very good. I have created a subset of 3 air photo tiles to repeat the tile cache creation process, the tiles turn into checkered boxes at 1:6770. Published the mosaic (right-click on it) as an image service and the result is same. The disk space is plenty on the file server and I have moved the files to a different file server. The issue is being looked at by ESRI Support (Australia) but I thought I may get some answers if posted in this forum. Has anyone have experienced this issue before? Thanks in advance for your help.

Thanks Melita for your practical advice. I was thinking about representing the Earth's surface as close to the reality as possible on our screens so when we measure a piece of land on the map, it equates exactly to the real-world measurement on Earth. Now, I remember I came across this proposed Discrete Global Grid System http://geoawesomeness.com/discrete-global-grid-system-dggs-new-reference-system/ which gets implemented, we might do away with all the different map projections.

As I was explaining to someone the concept of map projections (i.e., the act of projecting the earth sphere on to a flat sphere), I wondered this myself. Considering now that devices are able to capture and represent the 3D shape of the Earth more accurately, how relevant is the map projections relevant. The map projections could be used only when printing maps on to a flat paper. Keen to hear from others. Thanks, Thiru

Resolved this by following ESRI Support's advice of increasing the Server's RAM 8 GB and SQL Maximum memory to 4 GB. We had performance issues with another SDE server and by increasing the RAM from 16 to 64 GB, it made a big difference.

We had similar issue and found that our SDE database was locked out by a 'compress/index SDE' scheduled task. After terminating the hanging task, the SDE database was fine to accept user data submissions.

ArcMap users are getting the following error "Error: The app domain with specified version id (%d) was unloaded due to memory pressure and could not be found" and the draw performance is terrible. Our Environment: Virtual Machine Windows 2012 R2 with 5GB memory Standard Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: ) (Hypervisor) Microsoft SQL Server 2014 (SP2-CU7) (KB4032541) - 12.0.5556.0 (X64) (max memory set at 2 GB). Geodatabase version is 10.4.1 and matches ArcSDE version. User is using ArcMap 10.4.1.5686 Draw performance is terrible, geometry can take up to 5-10mins to draw. It started happening since last week. Previously there was no issue. Number of feature classes remain the same. No changes were applied to the server. Users are getting the AppDomain unload error popups. We do not publish web service from the server. Welcome any idea or work around to this. Thanks in advance.

Thanks Anthony, looks like I could use your logic. Christopher, the bigger ones are non-overlapping polygons. If the residual is one big polygon that doesn't make the 1 km by 1 km size, then it is fine. If there are many fragments that could make a combined total of more than a 1 km by 1 km grid I would like to have it split it subsequently. Thanks, Chris. The dice tool works only with ArcINFO. We don't have it. I wish I had the ArcEditor licens that has the Parcel Fabric tool..**sigh** Gday Yes there is a way. I would use the 'fishnet' tool to make the grid. Can't immediately help with the coding, but I would use the following process. # determine extent of your irregular polygon # create fishnet within that extent with your 1km parameters # clip fishnet polygon to the extent of your irregular polygon # union the clipped fishnet and your irregular polygon # clean up any unwanted fields Good luck!

Hi fellow members, I would like to split an irregular polygon into smaller uniform sized polygons i.e dividing a land parcel into many 1sqkm rectangular polygons and leaving the residual polygon as it is. Is there a script or function that can accomplish this task. I only have ArcGIS Basic and do not have a Parcel Editor extension or anything. Thanks in advance for pointing me in the right direction.

Hi, I would like to zoom to features and export the map data frame into JPEGs with world files. I have created an Index Grid shapefile that covers my area of interest. All I need to to is go through each row/record in the shapefile, zoom to extent and export the data frame as JPEG with worldfile. I am new to python programming. I have composed a python script (thanks to fellow members), but it is not working. import arcpy from arcpy import env from arcpy import mapping env.workspace = r"C:\temp\python" mxd = mapping.MapDocument(r"C:\Temp\Sample.mxd") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] for lyr in arcpy.mapping.ListLayers(mxd): lyr.visible = True fc = r"C:\Temp\Grid.shp" count = str(arcpy.GetCount_management(fc)) x = 0 while x < int(count) + 1: rows = arcpy.SearchCursor(fc, "FID = " + str(x)) for row in rows: df.zoomToSelectedFeatures() df.extent = lyr.getSelectedExtent() arcpy.RefreshActiveView() mapping.ExportToJPEG(mxd, r"C:\Temp\Map_" + str(x) + ".jpg", df, df_export_width=3004, df_export_height=2125, world_file=True) print('Exported image',x, 'of', count) x += 1 print("MXD to JPEGs Export successful") print("Thank you!") I would really appreciate your help in correcting this.
